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
DH-PFM88X max transmission distance can reach 5km, max transmission rate can reach 300Mbps,
and it also has excellent long-distance transmission performance, Its long-distance transmission
and high performance can meet the users’ demand of high bandwidth and long-distance
communication.
3. Integrated Watchdog
DH-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 DH-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
5.8G frequency band is relatively less. 5.8G device will be more susceptible to interference when
the use of 5.8G device is very extensive. However, DH-PFM88X products increased support for
5.8G nearby frequency, which will make the working frequency expand to 4920MHz-6100MHz.
Because the interference of some frequencies is very little, the client working in these frequencies
and performance of access point are better than other frequencies. DH-PFM88X’s support for
