anti-interference ability of device wireless transmission. PFM88X series wireless device owns following
advantages compared with other brand products:
1. Integrated Technology
PFM88X with built-in operating system integrated TDMA, which effectively solved the problem of
hidden node which bothers large-scale point-to-multipoint WLAN. Operating system adopts
advanced rate control algorithm which can quickly adapt to channel quality change and at the same
time keep the rate stable as much as possible. It is suitable for long-distance wireless transmission
and solved the problem of long-distance point-to-point access, which makes more access number
and rate distribution more average, which is fit for the application of operator and wireless
monitoring field.
2. Long Transmission Distance, High Throughput Rate
PFM88X max transmission distance can reach 5km, max transmission rate can reach 300Mbps,
and it also has excellent long-distance transmission performance, its throughput rate can reach
40Mbps at 3km and 30Mbps at 5km respectively. Its long-distance transmission and high
performance can meet the
users’ demand of high bandwidth and long-distance communication.
3. Integrated Watchdog
PFM88X integrated hardware watchdog which monitors system operation all the time. Once the
system works abnormally, watchdog will reset the system and make it restart, which effectively
guarantees the stability of PFM88X.
4. Ping Watchdog Function Real-time Detect Link
Ping Watchdog function can detect if the link works normally, it will help to restart the device when
malfunction occurs to the link, which guarantees stability of the link.
5. A great number of frequencies provided to users
Currently most wireless products are working in standard 802.115.8G frequency, but the standard
