Introduction to relay technology,Universal Wireless WiFi Range Extender

It is feasible to expand the scope of 802.11 network by using repeater technology. In fact, the IEEE 802.11 protocol has clearly defined several modes to support relay. For example, a wireless distributed system (WDS) allows an access point not only to connect with another access point on a wireless link, but also to provide services for 802.11 devices at the same time. If the bandwidth has little to do with the application, it has the greatest flexibility if 802.11b is used to expand the range. If the serving user and two-way transmission are using the same wireless communication channel, the available bandwidth has been substantially reduced by half.
In fact, in the network, the wireless repeater can be simply and narrowly referred to as the wireless AP.internet boosters

AP is the abbreviation of access point (wireless access node). It is equivalent to the hub or switch in wired network. However, it is a hub with wireless signal transmission function. It can provide a conversation intersection for multiple wireless Internet devices. Wireless AP is a name with a wide meaning. It not only includes a simple wireless access point (wireless AP), but also a general term for wireless routers and other devices. However, in order to distinguish these two types of devices, we generally call devices with AP function as wireless AP and APS with router function as wireless router.
Simply put, AP is the extension line, repeater and amplifier in wireless network. Play a role in strengthening the signal and extending the distance.

Under what circumstances is bandwidth distortion? Wi-Fi boosters?

The repeater can expand the coverage of 802.11 network, but we should pay attention to several problems. One thing to note is that the repeater must receive and forward frames on the same channel, which means that your bandwidth is actually divided into two halves. Although range is more important than bandwidth, the transmission rate of long-distance clients will be as low as 1Mbps. Due to the overhead of 802.11, only about half of the bandwidth can be used for data transmission. Because of the repeater, the bandwidth is divided into two halves again, especially when multiple users share the same channel, so you will encounter the problem of bandwidth.

Another problem to note is that some repeaters have only one omni-directional antenna, while some access points (which can enter repeater mode) have two antenna diversity. If you want to use a higher gain antenna to expand the range, use a multi-channel omni-directional antenna instead of a directional antenna anyway. When using the diversity antenna system, only one antenna can work at a time. Therefore, when the transmission is busy, it will not transmit in the opposite direction, resulting in interference and retransmission problems. Generally speaking, the effect of using multi-channel repeaters is not good. In short, the longer the wireless path, the higher the probability of failure.

As for which 802.11 standard is most suitable, even if the 802.11a frequency spectrum has fewer congestion problems than 802.11b/g, I also consider 802.11b/g because it has longer transmission distance, more fierce market competition and more equipment choices.
