Let's return the time back to 2008, Intel released a new low-power processor family, named Atom, the Chinese name is Atom, domestic players gave it a more familiar name - Astro Boy. This also blew the clarion call of Intel officially entering the mobile processor. Since then, Intel has developed a large number of related model processors and provided a large amount of subsidies to manufacturers. Due to Intel's shortcomings in mobile phone signal baseband, mobile phone manufacturers that use Atom processors were paralyzed; however, generous subsidies have attracted a large number of small vendors, plus Microsoft’s support for touch screens from WIN8 and the small screens. System license fee reduction, which makes a large number of relatively cheap windows or Windows Android dual system in a large number of the market, and because it can run all x86 version of the windows and .exe program, making people for the sale of the computer high above the The price quickly pulled down to 499 yuan or even lower. The label of Atom is just the limelight. Everybody thinks that intel is relying on Bluestar's strongest semiconductor technology to punch Apple in the foot and end the mobile computer era.
However, the unpredictable changes in the industry, after eight years of hard work and heavy investment, intel announced in 2016 that it will withdraw from the mobile device market, and will stop updating Atom series chips, and gradually reduce production capacity until the next frame.
Therefore, as the flagship model of the last Atom processor x7 8750 may be the last Astro Boy Prince model we can see. Therefore, this article's protagonist Taipower Tbook 16 Power is equipped with a piece of this processor, and manufacturers configure it with a huge memory of 8gb, in the same price as luxury. Well, Astro Boy's last ripple, I took it. Let's take a look at what kind of experience Tbook 16 Power can give us.
Before opening the box or first look at the configuration and positioning of this product, see the picture
The processor is the x7 8750 we said, the last Astro Boy flagship model, we will evaluate the performance later. But the price is not a cheap processor. The models currently on the market that carry this model generally cost more than 2,000 yuan. The flagship status cannot be lost.
As an old player who grew up with Astro Boy along the way, I experienced 2gb memory + win8, and I have to say that every use is a disaster. 4gb memory can be said to be a smooth use of the basic conditions of the win board, and Tbook 16 Power exception will be 8gb memory down to 2000 this price, it seems that Taipower this time to achieve the ultimate price, you know how much memory after boom7.
As for 64gb storage, to be honest, if it is a Windows system, it is fully enough, because atom does not support ssd and can only use emmc to store. This speed is not much different from that of tf card. I'm not as good as inserting cards to save costs. But since it is win+android dual system, 64gb storage space is certainly a bit stretched. But with cost control, cutting a knife here is inevitable.
The screen promotion mentioned is a 11.6-inch Full HD IPS screen, which can be considered as a non-full-fitting large gray screen. In fact, the material of the screen I think is the time when the so-called wall plate is the most falling price, because the non-full-fitted screen Compared with full-fit screens, the difference in visual perception is really too great.
Other details We talked about in detail in the out of the box, but for several large parts, Taipower's Tbook 16power is very cost-effective, it can be said that in the same price range rarely rivals, so we will be very vigilant in the following article Looking for the possibility of shrinking on other parts, if the shrinking part is not harmless, then the Tbook 16power will be a conscience board, and if it shrinks to the key part, this product may be a failed product. We will wait and see.
To unpack SF, there are two boxes for the Aunt's delivery. They are the main body of the Tbook 16power tablet and the matching magnetic keyboard. The packaging is quite simple, but the simpler I am, the more I like, because if the cost is controlled on the packaging, it will be able to effectively put the effective cost on the machine itself.
Unpacking, the same content, simple, except for the buffer layer consisting of paper shell foam, accessories only charger and type-c charging line.
Aside from these components that are sacrificed to control costs, let's take a look at the ontology. The appearance of Tbook 16power makes people think of a product. Yes, it is the appearance of the Surface Pro generation and the second generation. The style of the border with the fish outside the screen is really making people return to the Tablet PC 3 years ago. Aesthetics, in today's tablet PCs with 16:9 screen design should be rare, and so wide frame also lacks some sense of design.
Let's take a look at the interface settings on the side. The power button and the volume button are placed on the top left; there are two speaker openings on the right; on the left, there are almost all the interfaces integrated; the TF card slots are from top to bottom. miniDP port, mic, DC charging port, USB type-c, full size USB3.0 and 3.5mm headphone jack; and there is only one bayonet and contacts for the magnetic keyboard. From the interface, Tbook16 power can be described as sincere, comparable to many notebook products.
The design on the back is also very simple. The metal back panel is ground to a matte pattern. Although the support of the stepless adjustment is not as reliable as the Surface, it can be stably supported on the flat plate at most angles. The position of the rear camera is not directly behind, presumably to avoid certain components, but it is somewhat uncomfortable for obsessive-compulsive disorder.
Finally, let's take a look at the extra packaging of the magnetic keyboard. Although the packaging is as simple as ever, the keyboard's workmanship and feel are really good. Nothing inferior to Surface's keyboard accessories. It's just this color that I really can't appreciate. Both black and blue are better than the current mix and match style.
Look at the effect, and compare it with the tablet and laptop in my hands. You can see that if you compare the matebook, which is the ultimate light-weight two-in-one tablet, the Tbook16 power is bloated anyway; but we also have to Seeing that the rich interface provided by Tbook16 power is matebook, there is only one type-c interface that can be compared. The comparison of orthodox laptop products, Tbook16 power can be said to be very small, but because of the use of a metal body, Tbook16 power in weight is not much advantage, want to hold as a tablet to use must have a pair of unicorn arm can not be .
In general, the Tbook16 power is not colorful in appearance design. Although we can see solid materials and rich interfaces, the heavy body and generous frame still weaken the overall sense of technology. Between the easy-to-use and good-looking, Taipower undoubtedly focused on the front of the machine.
Whether you are a computer hardware or a light user, I believe all are very curious about the performance of this section of the tablet, after all, the last Astro Boy x8750 is also the focus of its propaganda, without a word, let's run it.
First and foremost, it is the score of entertainment masters. The latest version of Master Lu has greatly adjusted the selection criteria for CPU scores. Overall, the strong points are higher and the weaker points are lower. Running down the most intuitive experience is the graphic weakness, when running Lu master test demo full 10 frames below, and do not say that my big milk 1070 full 300 + frame, even the mini body with 860m alpha Can run around 170 frames. Judging from the results of running the results, it is basically expected that any desktop platform using standard voltage equipment will not be compared, and on mobile platforms, it is also in a relatively weak situation.
The unexpected point is that we mentioned earlier that the screen is a non-full-fit screen, and the device information shows that this is a 11.6-inch Full HD screen from Panasonic. Although the specific information of this screen cannot be found either in the search engine or in the screen library network, the brightness or color reproduction of the screen is above the pass level during use. I thought the screen would be a serious point of shrinking, but the performance is indeed acceptable and worthy of recognition.
Certainly a lot of people are curious, Core m devices can also be fanless, but also widely used in two-in-one devices, but the price is much higher than the atom, then how much difference in performance? ? The same comparison with matebook to see it, my hand this is the lowest version, the processor uses the core m 6y30, and z8750 is a generation of products, respectively, the core m family is the weakest and the atom family strongest, run under the contest It. From the results, it can be seen that regardless of whether Lu is a master or a pi, the core m leads the team with a high advantage. It seems that Intel’s gap between the two products is still quite large.
(Matebook m3 version running results)
However, in addition to running large programs and games that really affect the atom experience or its lack of support for SSDs, the mere support of emmc is the biggest ban on inspiring Astro Boy. From Master Lu's hard disk score you can see the difference, but with the AS ssd benchmark can not complete the running points, had to choose other software, Tbook16 power performance can be described as poor, or even worse than the HDD results, compared to other ssd in my hands The equipment is really low. This has severely affected the speed of program opening and response in daily use. It is believed that everyone who has experienced mechanical hard disk swapping can experience it.
Of course, if we want to use the PC industry standard to measure a 2in1 tablet with a price of 2k, it would be too harsh. We will return to our daily experience. Office software I do not think too much testing is certainly smooth, mainly focused on testing the video playback capabilities, I have tried 1080p, 4k 8bit samples, and 10bit samples, the decoder for perfect decoding. From the video playback is basically a pass.
For 2in1 tablet, the game is definitely a necessary and indispensable test item. Firstly, it tests the running conditions of mainstream online games. It wants to simply test three sets of Tencent. Unfortunately, the League of Legends and DNF are too large for the client to install smoothly. It seems that if you want to completely play on your computer, you must not release Android to free up hard disk space. The CF is small and smoothly installed. The frame rate under low configuration is also relatively smooth. It can be seen that the mainstream online game for everyone can not wait to play, the last Astro Boy can be playable, although for God-level people in the hands of people can be described as sniffing hard to swallow, but we are all from poor students Come on, there is a very big difference between yes and no.
The tradition of unit price testing is GTA5. Given that I bought the PS4 version, plus the space available, this is not a test. It's easy to test the independent games like Isaac and Famine in the steam. Smooth operation. The test time is not much and there is no situation of overheat and down-clocking. This may be due to the better heat dissipation of the metal backplane on the one hand, and it is due to the lunar month of the winter.
In addition, as the win board must mention as a butter board, do not play butter for many years, try the old game on the hard disk, the magic make the night performance is gorgeous, high requirements on the system resources; Hua Jing does not know how many generations it has come out. There are 2 generations on the hard disk to try the 2nd generation, because H scenes have a lot of animations and eat hardware; Lance as the most strategic game, pull the most strategic never Eating performance. Comprehensive test of the pressure scene, Tbook16 power can run smoothly, it seems that these pediatric butter can no longer be troubled Astro Boy tablet.
To say that there is a win board, whether it is ipad or Android tablet can not be compared to the application, it must be a ship woman, what? Did you say there is an Android client now? It's not a matter of not being able to run poi. It's a disrepair! I'm actually saying that I've been taking a pit for a long time and I'm also taking this opportunity to look at the old wives. Flash is currently regarded as a cancer in the industry by families including adobe, the parent company. It is said that no matter how much system resources can be eaten, it is by no means fictitious. When the Fleet Collection is operated, it is relatively smooth in the homeport, but in battle interfaces, especially It is the case that the air raid screen is a screen that exists in the last generation of 2g memory. The basic situation has not appeared yet. I think that in 2014, I can use the miix 2g memory to open the winter games of the year. It seems that no matter what the game is. Optimization or hardware advancement is not fast.
With the x86 architecture starting to support Android systems, many domestic tablet manufacturers tend to come with a free Android dual system. Of course, why don't you give away, Tbook16 power is also preloaded with Android dual system, and at the time of boot After entering windows, you can switch to Android system with one key, which is very convenient.
The random Android version is very similar to Google's native system, and comes with goapps, which runs smoothly. However, if you use it horizontally, the 16:9 tapefish resolution plus the taskbar and virtual buttons, the visual space Will be further cuts. It is also worth noting that the external magnetic keyboard is not available on Android.
Don't talk nonsense, run and score it, and the old rules and security Bunny plus Geekbench4, running points are as follows. It is roughly equivalent to the level of the Qualcomm Snapdragon 810, which is a lot lower than the scores of other mobile phones and tablet devices on hand. This is somewhat beyond my expectation. It is called the last Astro Boy. Your nuclear fusion furnace has only this ability. Is it a good one hundred thousand horsepower?
(left iPad pro, top right s7e, bottom iphone6s)
Let's take a look at the compatibility of the Android-based games. The compatibility of the early x86 version of Android was poor, and many 3D games could not be run. What happened to the current situation? We have chosen the most popular king of glory and testing procedures. Dietitians to test. The test results showed that no matter which of the above games can run smoothly, but the level of fluency is still good. Compared with the mobile phones in my hands, neither the number of frames nor the actual experience is too much. As an Android tablet, it is absolutely absolute. qualified.
Due to shortage of vacation time and lack of tools, coupled with logistical delays, I am sorry I cannot disassemble the machine to experience the heat dissipation and scalability. So these days I made a complete experience of Tbook16 power with a basic user rather than a hardware player. I do not like the name of the domestic flat-panel "family boards" because they are all officially registered companies. Official customers such as intel and other components are also officially registered in the Ministry of Industry and Information, and they are in the formal e-commerce platform. With the physical store sales, the word "walled" is nonsense. However, for consumers, there has never been a good thing in the heavens to drop pies. The reason why domestic flat-panels can achieve such a low price to accompany the high-performance originals is that, apart from the subsidies mentioned above by the component manufacturers, only Using the public model to reduce the design, even reducing the number of indicators that are not easily seen in the publicity to achieve profits. For example, on the Tbook16 power, we can see that its network card selection is that it does not support 5G networks. This basically condemns the death penalty of the game stream, and it also puts an end to the possibility of running a large-scale game on a tablet with poor performance. In addition, compared with the design of first-tier manufacturers, whether it is the iPad Pro that has been on the market for more than a year, or the Huawei matebook that has been involved in the 2in1 tablet field, the Tbook16 power is aesthetically pleasing to the outside world. It's very difficult to be called a product that people can't put it down, and it may be a problem to solve it.
However, it is not difficult for us to see the astigmatism point that this product manager, who is bound by price, wants to distribute with dancing, such as the introduction of 8gb memory in this price range, more and more programs are currently eating memory. 4gb memory has been popularized to the era of mobile phones, this measure can effectively improve the user's multi-tasking capabilities without worrying about the delay caused by the explosion of memory. The simultaneous mounting of the TF card slot, the full-size USB 3.0 interface and the type-c interface has greatly improved the usability of the product and is an essential part of its ability to become a productivity product. The magnetic keyboard and stylus (although I did not try it out) support the suspicion of replicating the surface, but it is harmless and good for the consumer.
But when it comes to the shortcomings, it is brought by the industry and big companies. Intel is nicknamed the toothpaste factory. Because of its rare rivals, the desktop processor has a large amount of new products that can improve by 5% to 10% each year. Make money, but in the mobile processor products still upgrade at this pace is no wonder that finally lost the field, in the ARM architecture single-core capability has been comparable to the core m era, still on the performance of the atom toothpaste, castration ssd, leaving him It can only be the coldness of the market.
In general, Tbook16 power is a product with a high degree of completion, but lacks a bright spot. Although manufacturers are very hard to create new ideas and highlights, it is still difficult to hide the performance of the last Astro Boy. For young people, if you don’t have a tablet, no laptop, no desktop, or even a cell phone that is lagging behind, this device will give you great satisfaction. It can satisfy almost all of you at a low price. Think of it, you can run most of the games on most platforms on the market, wrapping up your multimedia entertainment needs. But as long as you have already gathered these endless stream of digital products and just want to seek new things, this type of all-around and unrefined product will certainly not be able to enter your eyes. I think this is the reason why such product evaluations are so fragmented.
Tbook16 power
Advantages: 8gb large-capacity memory, complete interface, solid workmanship, cost-effective
Disadvantages: heavy, weak performance, low value
1. What wireless network
Wireless network, as the name suggests, is a way to build a network without relying on network cables, which is mainly achieved by using wireless communication technology. There are two main ways of wireless network (such as 4G, 3G or GPRS) and wireless local area network (WiFi) through mobile communication networks.
2, What wireless bridge
Wireless bridge, as the name suggests, is the bridge of wireless network, which uses wireless transmission to achieve a communication bridge between two or more networks. In addition to having the basic characteristics of a wired bridge, a wireless bridge works in the 2.4G or 5.8G wireless license-free frequency band, making it easier to deploy than other wired network equipment.
From the function to understand the wireless bridge, it can be used to connect two or more independent network segments, these independent network segments are usually located in different buildings, hundreds of meters to tens of kilometers apart, can be widely used in the interconnection between different buildings.
At the same time, according to different protocols, wireless Bridges can be divided into 802.11b, 802.11g and 802.11n in the 2.4GHz band and 802.11a and 802.11n wireless Bridges in the 5.8GHz band.
3, the meaning of wireless bridge 2.4G and 5.8G
2.4G Bridge:
The advantages are low frequency, large wavelength and strong diffraction ability. Simply put, the propagation performance is good, and the propagation path is slightly shielded. Then there is the relatively low cost.
The disadvantage is that there are many devices using the 2.4G band, and the electromagnetic wave signal emitted by the bridge is easily interfered with the signal emitted by other devices, resulting in a decrease in transmission quality. Moreover, it is limited by the transmission bandwidth of the 2.4GHz band itself, which generally does not exceed 300Mbps
5.8G Bridge:
The advantages are high frequency, relatively pure channel, and large transmission bandwidth. The transmission bandwidth starts at 433Mbps and can easily reach more than 1Gbps. It is suitable for scenarios that require high data transmission.
The disadvantage is that the frequency is high, the signal wavelength is short, the penetration is poor, and there can be no shelter during the propagation. The cost of 5.8G equipment is higher than 2.4G, and it is still in the popularization stage.
Wireless bridge transmission system is usually composed of two or more wireless devices, due to the two-way transmission of data, each device needs to have the ability to send and receive wireless signals.
4, the working principle of wireless bridge
The working principle of the wireless bridge is that the bridge uses the air as a medium to transmit signals, which is simply that one end of the bridge converts the signal in the network cable into a wireless electromagnetic wave signal and transmits it to the air in a directional manner. The bridge at the other end does the opposite, picking up radio electromagnetic signals in the air and converting them into wired signals.
The wireless electromagnetic wave signal can be transmitted by air as the transmission medium, which can solve many problems of difficult construction of wired deployment: such as highways, rivers, mountain streams, or road hardening, and wired deployment and construction difficulties.
Wireless bridge networking has obvious advantages, and can achieve point-to-point or point-to-multipoint network connections at distances of up to 50 kilometers, and data transmission speeds of up to 108Mbps. Effectively solve the problem of network connectivity in the interval, as long as the wireless signal coverage area, the client can easily access the network, the fusion system, without any wiring, the wireless terminal can achieve zero configuration access, so it is very easy to carry out network maintenance and expansion.
Bridges are generally used in the following scenarios: wireless data acquisition, monitoring data transmission (outdoor and elevator), outdoor wireless coverage, outdoor remote wireless bridging, private ISP wireless broadband, unmanned monitoring station data return, etc.
5. How to choose the right bridge
Wireless bridge is a wireless monitoring and transmission equipment commonly used in the field of wireless monitoring, although it is a wireless device like wireless AP and Wireless Router, but it does not need to build wifi coverage, but is used to wireless transmission of video data. Like the switch in wired monitoring, the wireless bridge is an important transmission equipment in wireless monitoring, which is widely used in the two major fields of outdoor surveillance video transmission and elevator surveillance video transmission.
There are many kinds of wireless Bridges on the market, so how to choose a bridge that suits your needs? We will answer your questions from the following aspects.
â‘ Transmission distance
Wireless monitoring projects need to transmit the distance is not the same, wireless bridge transmission distance there are many kinds, some transmission 1~3 km, some transmission 3~5 km, some transmission 5~10 km, some transmission more than 20 km, must be determined according to the monitoring of the transmission distance, as far as possible the maximum transmission distance of the bridge is greater than the monitoring transmission distance, Because rain, fog, snow and other weather in the actual application environment will cause the transmission performance of the bridge to decline, the project construction should reserve sufficient performance margin.
â‘¡ Transmission bandwidth
There are many kinds of transmission rates of wireless bridge, such as 150Mbps, 3000Mbps, 450Mbps, 600Mbps, 900Mbps, etc., which rate to choose can be determined according to wireless monitoring requirements. What users actually need to consider is the transmission performance of the bridge over a specific distance, rather than the theoretical bandwidth data. For example, the theoretical transmission bandwidth of the IP-COM AP625 bridge is 433Mbps, and the actual point-to-point transmission bandwidth can reach 200Mbps at a distance of 2 kilometers, with 25 200W cameras without pressure.
â‘¢ Operating frequency
There are two main operating frequencies of wireless Bridges, 2.4G and 5.8G, and the characteristics of the two Bridges are different. In general, 2.4G wireless bridge is the current mainstream frequency band, good compatibility, good diffraction ability, but the anti-interference is relatively poor, especially in the urban area is vulnerable to wireless signal interference transmitted by other WiFi devices. The 5.8G channel is relatively pure, the anti-interference ability is better, the transmission distance is long, but the diffraction ability is poor.
Urban, downtown, long-distance transmission, camera stream is large, 2.4G interference is more, choose 5.8G wireless bridge. Others such as the transmission distance is relatively close, relatively remote, and the same frequency interference is less, etc. 2.4G wireless bridge is used
â‘£ antenna
Antenna is an important part of wireless bridge, used to transmit and receive wireless signals, no antenna, wireless bridge can not achieve communication. There are many types of antennas, including omnidirectional antennas and directional antennas. Omnidirectional antenna is used for short-range coverage and transmission, and directional antenna should be selected for long-distance bridge. The larger the gain of antenna, the better the performance of wireless bridge.
⑤ Power supply mode
The working environment of the wireless bridge usually involves some complex outdoor environments, such as forests, ports, tunnels, reservoirs and other places, so the power supply is a more troublesome problem. Choosing a wireless bridge that supports POE cable power supply can solve this problem well. IP-COM bridge all support PoE injector power supply, power supply distance up to 60 meters.
â‘¥ Protection level
The wireless bridge works outdoors, the environment is changeable, such as rain, rain and snow, high temperature, etc., the first requirement is waterproof, dustproof, heat resistance, and condensation resistance. For a qualified wireless bridge, these "qualities" are a must.
⑦ Pairing method
At present, there are three mainstream bridge pairing methods: key pairing, dip code pairing, automatic pairing. In terms of the simplicity of engineering applications, especially for projects that install dozens or hundreds of network Bridges at a time, automatic pairing is undoubtedly the best choice. IP-COM network bridge supports the automatic pairing of two network Bridges when they are powered on in the factory state, greatly reducing the workload.
6, wireless bridge installation requirements
Wireless bridge is an important transmission equipment in wireless monitoring, which is widely used in outdoor surveillance video transmission and elevator surveillance video transmission. In addition to selecting the right wireless bridge, we also need the bridge equipment to give full play to its performance advantages after installation to assist users in the project. Therefore, for some installation requirements and precautions of wireless bridge, we should pay more attention to avoid various problems in the later stage.
â‘ Installation height
In the process of wireless transmission, obstacles such as trees, buildings and large reinforced buildings will weaken and block wireless signals. In order to improve the wireless transmission performance and prevent signal damage and weak signal, the user should try to ensure that there are no obstacles in the transmission route of the wireless bridge during installation, and meet the transmission conditions that the two ends can see each other.
Both ends can not be simply understood as point-to-point visibility, which means that there can be no obstacles or potential obstacles in the Fresnel zone (radio wave terminology) in which the antenna is propagated. The main RF energy between the antennas is transmitted in this area, so the transmitting antenna must be high enough above the obstacle to maintain a line of sight path between it and the receiving antenna in order for the communication link to work properly.
â‘¡ Angle and signal debugging
Since the quality of the wireless bridge signal is directly related to the bandwidth and stability of the link, it is necessary to further debug the wireless bridge signal after the installation is completed (the signal strength can be adjusted by adjusting the direction of the antenna on both sides, the pitch Angle, etc.). The signal strength can be checked according to the signal status indicator of the bridge device (three lights, three signals are best, two are average, and one is poor) or the software. Detailed installation procedure for outdoor wireless aps
â‘¢ Requirements for lightning rod
When the wireless bridge is installed in the field, if there are no tall buildings or lightning rod protection nearby, lightning protection measures need to be considered, usually using lightning rod, generally installed in the urban area or surrounded by lightning rod protection, can not be set separately.
It can be seen from the characteristics of the lightning rod that the lightning rod is a lightning source, and the lightning rod will discharge in the grounding path when it is hit by lightning. Therefore, the lightning rod and the protected equipment need to be insulated, otherwise the lightning rod will have a lightning effect on other equipment when discharging. Due to the tip discharge characteristics of the lightning rod, it is easier to cause lightning discharge than the general equipment, so if the lightning rod cannot be isolated from the protected equipment, it will increase the probability of lightning strikes of other equipment. Therefore, the lightning rod grounding must be separate from the device grounding and cannot share the same grounding.

Register an account and you can publish business information on more than 10 platforms for permanent display. Colleagues are on the move, you must not forget oh.
â‘£ Power supply requirements
The normal input voltage of the PoE power module of the bridge ranges from 100V to 240V and the output voltage ranges from 24V to 48V. If the voltage is lower than or higher than this voltage, the normal operation of the device is affected or the PoE power module is damaged. In view of the unstable and high voltage field power supply, it is necessary to design a PoE power supply solution (such as regulated power supply and UPS power supply) that ADAPTS to the working voltage.
Because the bridge is a precision electronic equipment, it has high requirements for power supply, and is vulnerable to the impact and influence of other power supply equipment, so the power supply of the bridge should be separated from other high-power equipment such as pumping units, oil pumps, etc. When taking power at the same location, UPS, regulated power supply or isolation transformer should be installed to filter out the influence and interference on the power supply when the high-power motor is working.
When the PoE module is used to power the bridge through the network cable, the recommended distance is not more than 60 meters. When this distance is exceeded, it is recommended to move the transmission line near the bridge to meet the recommended power supply distance.
⑤ Device grounding requirements
The wireless bridge should be grounded. If the device is not grounded, the device may run abnormally or be damaged. The grounding resistance of the device should be less than 4 ohms, and the grounding cannot be shared with the lightning rod or strong current line. If PoE power is used, the ground cable also needs to be grounded. Users can ground a Class 5 (or higher) shielded network cable with a ground cable and a PoE adapter to effectively prevent static electricity and lightning strikes. The ground cable and ground point should be waterproof using waterproof tape and waterproof cement according to the waterproof requirements to prevent the ground point from being exposed to the air for a long time, which may cause oxidation or rust.
7, wireless bridge erection method
There are four common wireless bridge transmission modes, the distribution is point-to-point, point-to-multipoint, relay, reflection, here the first monitoring combined with pictures for you to briefly introduce the characteristics of these four wireless transmission modes.
â‘ point-to-point transmission
Point-to-point transmission mode is the simplest transmission mode, that is, we often say PTP, to a single device transmission, and then received by a single device, one-to-one transmission and reception is simple and direct. Point-to-point transmission mode of wireless bridge is often used in the case that the transmission distance is long, or the monitoring point is widely distributed, and point-to-multipoint transmission cannot be achieved.
â‘¡ Point-to-multipoint transmission
The point-to-multipoint transmission mode is developed based on the point-to-point transmission mode, which is often represented as a receiving end to multiple transmitting ends, and is often used for the situation where the transmission distance is relatively close, there are more monitoring points and the distribution is dense.
â‘¢ Relay transmission
The relay transmission mode is because the transmitting end and the receiving end can not avoid the barrier blocking the microwave signal, so the transfer equipment is added in the middle, so that the microwave signal is smoothly transmitted to the receiving end through the transfer equipment, this mode is due to increase the transfer equipment and increase the equipment cost investment, so it is generally not used when unnecessary.
â‘£ Reflection transmission
Reflection transmission is microwave transmission with the help of objects outside the transmission device, such as the transmitting end and the receiving end can not be seen, but there is a large building or a mountain with smooth rock walls in the middle, so that you can adjust the Angle of the equipment, through the building or mountain to reflect microwave signals for wireless communication.
