environment. Users can detect the following steps to make sure the max possible connection rate is
obtained.
(1) The location of wireless access point
Try to adjust the location and direction of wireless access point.
(2) Wireless channel
The interference could be obviously improved if you use other communication channel;
(3) Wireless interference
Other devices may also cause interference, so try to shut off other devices and check if the situation is
improved. Users also can shield the devices which cause interference or adjust the position.
4. The signal intensity is too low.
(1) It is not visible between CPE and AP due to bigger blocks.
(2) The surface plate of CPE doesn
’t face AP directly; the vertical angle between AP and CPE is not
suitable.
(3) CPE is installed on the window, which may cause interference.
(4) The distance between AP and CPE is too far.
5. Why is the signal intensity high but the throughput capacity low?
Reasons:
(1) Too much interference or multipath interference.
(2) Something is wrong with the device Ethernet port.
6. Frequent packet loss, serious packet loss with several devices in the same area, it will be
better when communication channel is changed.
Same frequency interference will be caused if several PFM88X are used in the same area without
separate the channels of two devices. Users are recommended to separate the frequencies of them so
as not to make the communication channels overlapped. It is recommended to make the frequency
