Algoritmo Cisco RRM - Potência

Algoritmo de Coverage Hole: Usado para aumentar a potência do AP.

Client SNR Cutoff = (AP transmit power) – 17 (Constante) – (Coverage threshold - Padrão 12)

AP Transmit Power para 2.4Ghz

Level 1 = 20

Level 2 = 17

Level 3 = 14

Level 4 = 11

Level 5 = 9

Level 6 = 6

Level 7 = 3

Level 8 = 0

Algoritmo de Transmit Power Control: Usado para reduzir a potência do AP. Todo AP começa a transmitir na potência máxima quando retirado da caixa.

1) Existem 3 APs com mais de -70dbm?

2) (Tx_Max) + ([Transmit Power Level Threshold] – (Terceira menor potência dos APs Vizinhos)).

Para 2.4Ghz TX_MAX = 20

Para 5.0Ghz TX_MAX = 17

3) Se o valor for maior que 6db, a potência é reduzida um nível, ou seja, em 3db.
