What is a wireless repeater and what is the optimal way to use it?
You can use a wireless repeater such as the FRITZ!WLAN Repeater to increase the range of your wireless network. The wireless repeater is connected to the wireless network of a wireless router, such as the FRITZ!Box, and then it makes its own additional wireless network available; wireless devices connected to it can then access your home network. Thus, the signal of the existing wireless network is not amplified by the wireless repeater, it is repeated.
To achieve optimal results when increasing the range, you should consider the existing infrastructure when choosing the wireless repeater and observe a few principles when positioning it. In this guide, we give you advice on selecting the perfect wireless repeater for your home network.
Can I use all wireless repeaters with my wireless router?
Pure wireless repeaters like the FRITZ!WLAN Repeater use the "Universal Repeater Mode" procedure and behave like conventional wireless devices towards wireless routers. This means that you can use this type of wireless repeater with all conventional wireless routers.
Some wireless routers can also be used as wireless repeaters. However, wireless routers usually use manufacturer-specific methods, which is why they often can only be used as wireless repeaters with routers from the same manufacturer.
Can I use more than one wireless repeater?
Yes, it is possible to use more than one wireless repeater. They can either be connected directly with the wireless router to increase the range in different directions, or they can be connected with each other (wireless cascading ) to increase the range in a particular direction. All current FRITZ! products with wireless capacities can be cascaded as Mesh repeaters in the FRITZ!Box's Mesh.
Does a wireless repeater reduce the wireless speed?
This is not always the case. With most wireless repeaters, the bandwidth for wireless devices is halved because they only have a single transmitter and receiver unit (radio), which means that it cannot simultaneously send and receive. For example, while the wireless repeater receives a data package from a wireless device, it cannot forward it directly to the wireless router; instead, it must wait until the wireless device has finished transmitting the data package to the wireless repeater.
This is different with wireless repeaters with two radios, for example the FRITZ!WLAN Repeater 1750E. When used with a wireless router that also has two radios, for example the FRITZ!Box 7590, data can always be transmitted without waiting if crossband repeating is used.
What is crossband repeating and how does it work?
Crossband repeating is a procedure where the wireless repeater and wireless router are connected over one particular frequency band, but wireless devices are connected with the wireless repeater's other frequency band.
For example, if a wireless device is connected to a wireless repeater via the 5 GHz frequency band, then the wireless repeater uses the 2.4 GHz frequency band for the connection to the wireless router. There is no loss of speed because each frequency band uses its own transmitter and receiver unit, and data packets can therefore be forwarded continuously.
The FRITZ!WLAN Repeater takes it even a step further; in addition to the crossband repeating procedure, it can flexibly select the frequency band for the connection between the wireless repeater and wireless router; this way the best setting is automatically selected for the current transmission situation.
Where should I position a wireless repeater?
If the repeater is connected to the wireless router over wireless LAN, it must be located within the range of the wireless network so that both of the wireless networks overlap. Since the wireless repeater is connected with the wireless router's wireless network, it must be placed where the quality of the router's wireless signal is good. If the wireless router and wireless repeater also use the same wireless settings, wireless devices can register with the wireless network with the best signal strength, with virtually no interruptions. Switching between both wireless networks is called roaming.
An optimal location for the repeater is somewhere where there are as few obstacles as possible between it, the wireless router, and other wireless devices. Especially metallic objects or objects containing water, for example radiators, refrigerators, or even houseplants, significantly reduce the quality of the wireless signal. A wireless repeater should also be placed away from other transmitters such as microwaves, baby monitors, wireless speakers, or Bluetooth devices. FRITZ!App WLAN allows you to easily find the ideal location for wireless repeaters.
Many wireless repeaters also have a LAN port, for example the FRITZ!WLAN Repeater 1750E, that allows you to also position the wireless repeater outside the wireless router's wireless range. This way, wireless devices can gain wireless access to your home network even at a great distance from the wireless router. For the connection between the wireless repeater and wireless router, you can either use a LAN cable up to 100 meters in length, or you can also use powerline adapters, such as FRITZ!Powerline.
