Hi everyone!
I have a small question, when
comparing two transceiver chips, I read something
about Adjacent channel power (ACP). Can anyone tell
me what Adjacent channel power means?
And
for a good performance, is it beter to have a high
or low ACP??
Tranks!
Enno.

Greetings Mr. Enno: As the name suggests,
adjacent channel power is the amount of power a
transmitter allows to "bleed" into the channel just
above and below it. Lower ACPs are always better,
because it means you are not as likely to interfere
with a co-existing system trying to operate in the
same frequency space. Here is an illustration
that uses co-existence of Zigbee with WiFi. Bluetooth
could also be added to the picture because like
ZigBee, it uses a frequency-hopping spread spectrum
scheme.
