Which option will allow the maximum 2.4 GHz channel usage for a survey and voice deployment in the ETSI domain?
A. 1,6,11
B. 1,5,9,13
C. 1,6,9,14
D. 1,6,11,14
Which option will allow the maximum 2.4 GHz channel usage for a survey and voice deployment in the ETSI domain?
considering maximum channel usage it would be 1,5,9,13
The answer is A because the question references voice. If not, then it would be B.
Therefore, it is common in the ETSI domain to see deployments using OFDM (“pure 802.11g,” and not 802.11b/g), using channels 1, 5, 9, and 13. This configuration allows for four “almost-adjacent” channels in the same space, and therefore allows for more clients in the same physical space. The downside is twofold:
Although this deployment is acceptable for data networks, the rise of the noise floor renders this type of configuration unacceptable for VoWLAN deployments, where one concern is to maintain a high SNR, even at the cell edge.
A is correct
Consider that the majority of the world agrees on 1,6,11 and most radios will default to this channel plan – in such a case if you have selected 1,5,9,13 any radio using the standard channels will interfere with at least one – in most cases 2 of your channels – We do not recommend it for these reasons.
A) Correct
it could be B
B in the ETSI
