Q:What is a repeater for?
It completes the connection of the physical circuit, amplifies the attenuated signal and remains the same as the original data. In general, both ends of the repeater are connected to the same media, but some repeaters can also do the switching of different media. In theory, the use of repeaters is unlimited, and the network can therefore be indefinitely extended. In fact, this is impossible, because the network standards are specific to the delay range of the signal, the repeater can only work effectively within this set of regulations, otherwise it will cause network failure.
Q:Can Tengda F6 repeaters be controlled by mobile phones?
The repeater is the most simple and inexpensive networking equipment under the LAN environment to extend the network distance, the operation of OSI in physical layer, the repeater has a regenerative amplifier function for the signal on the line, to extend the LAN segment length (only for connecting the same LAN segment).
Q:Request WiFi repeater settings, I do not know the other router's model and password, but I know the WiFi password!
The first step is to find the brand model of the other router. The second step is to buy a router that is compatible with each other's router, and basically compatible with the same brand. The third part is setting up.
Q:How does the relay set up the connection WiFi?
Use the new address to log on the route, open its wireless, set up and wireless bridging routers like the channel, SSID, password type, password and other data, turn off its DHCP and tick WDS,Then fill in or scan the broadcast name of the higher level wireless router and other data.Almost. For these basic steps, don't forget to save the settings.
Q:What does a network node mean? What does a repeater do?. Generally speaking, thank you
The devices that have your own network address are network nodes, such as your company's workstations, servers, your home router, and fax machines.
Q:Speed issues on wireless repeaters
If you want to expand the coverage, it is recommended not to use repeaters, buy two new wireless routers, set as main route WIFI name, the same as encryption, password, not the same frequency (1, 6, 11 recommended three completely nonoverlapping bands), close DHCP server (the main route have a DHCP server), the main route LAN port is connected with a new route LAN (not WAN). This will not cause interference or seamless roaming between the 3 routes, and the device will automatically switch the signal strong.
Q:The repeater connects to the wireless network of the left neighbor's home, showing the wireless channel -1, and even the wireless network on the right side shows the wireless channel -6. What does that mean?
General wireless devices operating at around 2.4G, and in this sphere is divided into 13 sections, namely 13 channel, 1 channel center frequency is 2.412G, the effective bandwidth is 20M, the actual 22M, wherein 2M is isolated from the channel bandwidth, 1 to 13, in order to superposition. Wireless devices can be artificially set up in these 13 frequency ranges.
Q:What is the difference between an amplifier and a repeater?
Amplifier: one of the most familiar and most commonly used audio processing circuits is common operational amplifiers. The general can be regarded as a simple operational amplifier with a signal output port (Out) high gain direct coupling voltage and in-phase and antiphase two high impedance input terminal of the amplifying unit, thus making in-phase and antiphase and differential amplifier using operational amplifier
Q:What brand of network repeaters is best?
Many of the major brands in China are of good quality.Shopping also takes into account your network and the number of users you use and connect to your environment.
Q:The greater the power, the better the ability of the WiFi repeater to receive the signal?
The sensitivity of the receiver generally has a limit, or the maximum reception sensitivity is a constant, and the reception capacity is limited by the sensitivity constant. It does not change as the power of the transmitter increases or decreases. It has nothing to do with the transmitted power. They are two different devices. It can only be said that the greater the power, the stronger the received signal.
