1 Product Overview
DH-PFM88X series device is a device with unique built-in TDMA wireless technology, which
integrates industry-leading core technology and has the features of long distance transmission, high
throughput rate and strong anti-interference.
TDMA，20M/40MHz bandwidth flexible configuration, rate control, ACK overtime auto adjustment
and etc. TDMA effectively solved the problem of hidden node which bothers large-scale
point-to-multipoint WLAN. 20M/40MHz bandwidth flexible configuration achieved a balance between
scarce wireless bandwidth resource and complex working scenario. Advanced rate control algorithm can
quickly adapt to channel quality change and at the same time keep the rate stable as much as possible.
Auto ACK-Timeout Adjust technology can auto detect the distance between access point and client;
adjust wireless parameter to optimize the device performance.
DH-PFM880 max transmission distance can reach 5km, max transmission rate can reach 300Mbps,
and it also has excellent long-distance transmission performance, It can be used as wireless bridge
between point-to-point and point-to-multipoint remote access, and a base station AP for WI-FI wireless
coverage.
