Q:WIFI how does the repeater amplify the amplified signal?
Like repeaters in old Ethernet, repeaters in old token ring networks have the same principle: signal reduction and amplification.As long as the signal is generated by electricity, whether wired or wireless or waves will have an attenuation and distortion, attenuation is due to the distance from the distortion of interference, attenuation is inevitable, the distortion can be avoided or improved.
Q:What's the function of repeaters in fire fighting engineering?
When the faulty part of the bus is repaired, the isolator can work itself back, and the isolated part is re incorporated into the system. The relay module is installed at the front end of each branch circuit of the two bus circuit and will be automatically disconnected when the branch circuit is short circuited.
Q:How can wireless AP (trunking) be used to connect wireless routers that shut down SSID broadcasts?
Either switch on the radio or use the cable. So far the repeaters on the market are like this!
Q:How can there be a walkie talkie in the absence of walkie talkies and repeaters? 30KM. My friend succeeded and didn't know how to set it up.
At present the intercom far more than 10 km far or in no obstacles or ideal conditions can have, you said thirty KM theory is not possible, unless he is using a digital radio base station into the network, then the conditional can interphone, there may be he cheated on you he used the relay station did not say with you,
Q:The role of field bus PROFIBUS DP/FMS isolation repeater is also discussed
As far as DP is concerned, a repeater must be added every 32 DP devices according to specifications. The relay acts as follows1, photoelectric isolation signal, 2, can change the topology (if necessary, can produce a tree branch) 3, cut and cut terminal resistance4, to enhance the signal, optimize the waveform and extend the communication distance
Q:How is the EDUP2930 repeater relay mode set up?
In addition, consider the following installation techniques:1. install the relay first in a very good signal position. In order for repeaters to work properly, doing so can greatly reduce the problem.2. upgrade the firmware of the repeater. Before the installation process, check that your repeater has the latest firmware version.3. configure the IP address. Make sure that the address of the repeater is unique and that it belongs to the IP address range that the wireless network connection can confirm. In most cases, the default IP address can be used, but you need to check the existing access point to confirm it.4. configure SSID. To set it exactly the same as the SSID on the existing network. If this step is not made, the repeater will never work unless the repeater fails, and it automatically scans the neighboring access points, automatically configuring this configuration for the user.5. configure radio frequency channels. The user needs to set up radio frequency on the repeater so that it matches the settings on the existing access point. This is similar to that of SSID. If the channel is set differently from the access point, the repeater will not work properly.
Q:How can I use a wireless repeater where there is no power?
Where there is no power supply, if the wireless repeater is 12V, it can be powered directly by the 12V battery.
Q:Repeater! Plug in, mobile phone search can not signal why?
First of all, you need to see if your repeater is on the phone, and you can search anywhere from one to two cells to stabilize your router's WiFi signals
Q:How does the jCG wireless router set up the Q5 repeater?
Set the main router (legend is FAST brand):1, enter the router management page, set the LAN port IP:192.168.1.1 (keep the default settings);2, DHCP service settings: enabled (must be enabled);3, SSID number: WIFI user name, can be changed to remember, the default is. Bridge router to scan, select the number;Channel: 6 (1 or 11). The bridge should be consistent with this channel from the router;Start wireless function: tick;Turn on SSID radio: tick;Account No. WDS: no tick;4, wireless security settings: select WPA-PSK/WPA2-PSK;Authentication type; automatic;Encryption algorithm: automatic;PSK password: WIFI password, these 4 settings must be consistent with those from the router;5, save, restart the router.
Q:What is the difference in functionality between the hub and the repeater?
The hub (Hub) is a form of repeaters, the difference lies in the hub can provide multi port services, also known as multi port repeater. The physical layer of the hub in the OSI/RM
