How to prevent interference from wireless routers

- Aug 02, 2018-

With the development of technology, the wireless routers in Shenzhen will judge according to the location of the client. Only the clients in the overlapping areas of the two APs will start balancing and let their clients access the APs with light load. This greatly reduces the mutual interference. .

1. Packet rate adjustment is to dynamically calculate the rate at which each packet is sent. Whenever a packet is sent or retransmitted, the client considers the signal strength and historical transmission information of the client. The appropriate transmission rate.

2. When the transmission fails, different rate adjustment algorithms can be used according to different environments. In a high-density environment, packet transmission failure is generally caused by packet collision. When a very low transmission packet is used, it will only result in transmission. The length of the air interface of the packet becomes longer, and the scope of the impact is larger, resulting in a more likely conflict, causing other APs to further reduce the transmission rate, so that the entire network is in a low performance state. Only high-rate retransmission is adopted, and even if the multiple transmissions are unsuccessful, the upper layer retransmission mechanism can be utilized, and finally the availability of the upper layer application is not affected.

3. The purpose of packet-by-packet power control and RRM dynamically adjusting AP power is to reduce interference between intra-frequency APs. When sending each packet, H3CAP adjusts the transmit power of the current packet according to the RF status of the client. The packet-by-packet power control minimizes the range of signal transmission effects and also ensures the coverage of the AP.
