WiFi STANDARDS
802.11a
802.11b
802.11g
802.11n
802.11ac


DATA RATES
Data rates vary with modulation types.
802.11b: 1, 2, 5.5, 11 Mbps
 2.4 GHz.
802.11g: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54 Mbps
 2.4 GHz. Can revert to 1, 2, 5.5, and 11 Mbps using DSSS and CCK.
802.11a: 6, 9, 12, 18, 24, 36, 48, 54 Mbps
 5GHz, 12 non-overlapping channels.
802.11n: 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps
 2.4 GHz or 5 GHz
 OFDM using multiple-input/multiple-output (MIMO) and channel bonding (CB)
 Mode		Maximum rate		Antenna transmit/receive
 1x1 20 MHz	72.2 Mbps		1 TX 1 RX	
 1x1 40 Mhz	150 Mbps		1 TX 1 RX	
 2x2 20 MHz	144.4 Mbps		2 TX 2 RX	
 2x2 40 MHz	300 Mbps		2 TX 2 RX	
 3x3 20 MHz	216.7 Mbps		3 TX 3 RX	
 3x3 40 MHz	450 Mbps		3 TX 3 RX
 To run at maximum speed Wireless-N routers and network adapters must be linked
 and running in CB mode which uses two adjacent channels to double wireless
 link bandwidth compared to 802.11b/g. CB is not enabled as default because
 it increases risk of interference due to increased spectrum and power.

WPA-PSK [TKIP] may only operate at "Up to 54Mbps" rate, not N rate.
Netgear recommends you use WPA2-PSK [AES] to get full N rate support.

POWER LEVELS
Definition: dBm means dB relative to 1 milliwatt. So 0 dBm = 1 mW
30 dBm (1 W) 
27 dBm (500 mW) 
22 dBm (160 mW)
10 dBm (10 mW)
7 dBm (5 mW)
4 dBm (2.5 mW)
1 dBm (1.25 mW) 
0 dBm (1 mW)
