为了进一步节约电量,在OFDM调制方式下,当传输速率达到此调制方式的最大值时尝试降低发射功率,即APC(Automatic Power Control)。目前11a/g 54 Mbps不支持APC,仅11n mcs7支持。即在11n mcs7下会尝试将功率直接降为0dBm,如果能维持per和Qos(服务质量),功率稳定在0dBm;如果PER恶化,则恢复NV中设置的发射功率...
19、IEEE 802.11n 有多少种速率? IEEE 802.11n使用 OFDM 调制方式,可以调制方式和符号速率搭配,定义 0 ~ 31 个MCS索引,每个 MCS 索引都有一个数据传输速率。 数据传输速率根据信道带宽和保护间隔( GI )的组合,在每个 MCS 中有四种模式。 使用20MHz 的信道带宽叫做HT20 模式,使用 40MHz 的信道带宽叫做HT40 ...
