Dahua 5.8GHz Wireless AP/CPE User Manual
- 3 -
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, 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. PFM88X
’s support for non-standard
frequency reduced the interference from outside wireless products and effectively improved the
throughput rate of PFM88X, which will meet users
’ demand for high bandwidth.
Attention:
Please confirm if it conforms to local laws and regulations and radio management
regulations before using these non-standard frequency bands.
6. Adapt to complex working environment
PFM88X can work in complex environment, working temperature is between -30
℃
and 70
℃
,
working humidity is between 5
％
and 95
％
. PFM88X can still maintain high throughput rate if it
works in thunderstorm, high temperature high humidity, low temperature low humidity and other
severe weather conditions for a long time.
