CW9163E is limited to 15db max transmit power of UNII-1 channel while cw9162e is not.

Regulatory Domain is SRRC.

On most Regulatory Domains the higher channels allow higher transmit power.

Thanks for your reply.  I understand this regulatory restrict for transmit power base on channels .But why for the same channel ,9162 can run higher power thans 9163 ?

@EricZ the maximum power includes the antenna gain.  What antennas are you using with the CW1963E?  You need to compare their gain with the CW9162 integrated ones.

CW9162:

Antenna

Integrated omni-directional antennas  2.4 GHz: Peak gain 4 dBi, internal antenna, omnidirectional in azimuth 5 GHz: Peak gain 5 dBi, internal antenna, omnidirectional in azimuth 6 GHz: Peak gain 5 dBi, internal antenna, omnidirectional in azimuth

CW9163E options:

Antennas

CW-ANT-O1-NS-00 Omnidirectional Dipole Self-Identifying Antenna with N-Type Connectors 2.4GHz: Peak gain 4 dBi, omnidirectional in azimuth 5GHz: Peak gain 8 dBi, omnidirectional in azimuth 6GHz: Peak gain 8 dBi, omnidirectional in azimuth One antenna per pack.  Four antennas are required to fully populate all ports. CW-ANT-D1-NS-00 4-Port Directional Patch Self-Identifying Antenna with N-Type Connectors 2.4 GHz: Peak gain 8 dBi, directional antenna, (75x30) 5 GHz: Peak gain 9 dBi, directional antenna, (60x30) 6 GHz: Peak gain 9 dBi, directional antenna, (72x27)   CW-ANT-GPS2-S-00 Active GNSS/GPS Antenna with RP-SMA Connector Optional GNSS/GPS external antenna L1/L5 frequency bands Integrated mounting bracket for wall or pole mounting 10ft cable with RP-SMA connector

[cmr · Accepted solution]

Therefore for the 5GHz band, the CW9163E max power should be 3dBm lower when using the omnidirectional antennas.  I can confirm through testing that the max power with the directional antenna is lower as expected.

The power indicated in the screenshots you shared is the transmit power in the radio without including the antenna gain.  Your CW9163e likely has the dipole antennas installed which have a 8 dBi gain.  The internal CW9162i antenna have a gain of 5 dBi gain.

We are using CW-ANT-O1-NS for CW9163E ,that makes sense for me. I really appreciated your detailed explaination .
