Product Overview
DH-PFM881 is a powerful WIFI Bridge/AP/CPE device, which allows WIFI access
and video/audio/data transmission device, enables long-range, fast speed and
robust wireless connections. Integrated with the XTrans technology, DH-PFM881
has the advantages of long-distance, high-throughput, and Strong
anti-interference.
XTrans technologies include TDMA, 5M/10M/20M/40MHz bandwidth, intelligent
rate control, Auto ACK Time-Out Adjust and so on. TDMA technology solves the
problems of hidden-node problem in the 802.11 network. 5M/10M/20M/40MHz
bandwidth can be flexibly configured by the uses in different working scenario to
achieve the best link quality. Intelligent rate control algorithm can be adapted to
quick channel quality variations automatically, thus stabilizing the wireless
throughput. ACK Time-Out Auto Adjust can automatically detect the distances of
the DH-PFM881 devices, and thus adjust the wireless parameters to achieve the
best wireless link quality.
The best transmission range and max speed of DH-PFM881 can be as high as
15Km and 300Mbps, making it suitable for many applications of WIFI Bridge/CPE,
especially have advantages for point-to-multi-point communication.
1.1
Product Advantages
The DH-PFM881 has the industrial leading technology, owing the performance
capability of a wireless base station with only a small form factor, furthermore, it
has very attractive low cost.
DH-PFM881 has the following advantages compared to the competitors:
1.
Embedded TDMA technology
DH-PFM881 devices is embedded with TDMA technology, including TDMA,
5/10/20/40MHz bandwidth, intelligent rate control, Auto ACK Time-out adjust.
They make the device have longer transmission distance, higher throughput and
better point-to-multi-point performance.
2.
Longer transmission distance, higher throughput
The longest transmission distance of DH-PFM881 can be as far as 15 km, and the
max throughput can be 300Mbps. It can satisfy the needs of most of the
applications.
