请问一下有谁知道IEEE802.11的a b g这三种标准有那些显着的不同吗?
我外国朋友写的
看不懂拉!....>_<
1.In high speed or heavy usage environments
802.11b is quickly being replaced by a new standard
802.11g, which uses the same 2.4GHz radio band,
but at 54Mbps, is almost five times faster.
The third wireless network standard is 802.11a,
which also runs at 54Mbps,
but operates in the less-crowded 5GHz radio band.
2.802.11a: The IEEE standard that governs the deployment of 5GHz OFDM systems.
It specifies the implementation of the physical layer for wireless UNII b.
802.11b:An international IEEE standard for WLAN networks,
operating at 2.4GHz and providing a maximum data transfer rate of 11Mbps.
802.11g: A proposed standard that describes a wireless networking method for
a WLAN that operates in the 2.4GHz radio band
It transfers data at up to 54 Mbps.

1F：推 cfleu:速度以及使用频带,接下来就是调变的方式 58.99.57.8 06/15
2F：→ cfleu:g是为了让a与b下的产物,可以向下相容b 58.99.57.8 06/15
