Wireless LAN Specification List
IEEE802.11a
Item
Specification
Conforming standard
IEEE802.11a
Communication modes
54/48/36/24/18/12/9/6 (Mbps mode)*1
Modulation method
OFDM mode
Wireless channels
36ch, 40ch, 44ch, 48ch, 52ch, 56ch, 60ch, 64ch, 100ch, 104ch, 108ch,
112ch, 116ch, 120ch, 124ch, 128ch, 132ch, 136ch, 140ch (passive
scanning)*2
Frequency band
5GHz band (5.15 to 5.35GHz, 5.47 to 5.725GHz)
*1:
These communication modes are based on the theoretical communication rate in the standard
and thus do not match effective rates. Such factors as connected devices, radiowave
environment, surrounding obstacles, installation environment, usage status and used OS,
applications and software may affect communication rate and distance.
*2:
It may take much time to connect US40a to a passive scanning channel.
IEEE802.11b/g
Item
Specification
Conforming standard
IEEE802.11g, IEEE802.11b
Communication mode
IEEE802.11g mode: 54/48/36/24/18/12/9/6 (Mbps mode)*1
IEEE802.11b mode: 11/5.5/2/1 (Mbps mode)*1
Modulation method
OFDM method (in 54/48/36/24/18/12/9/6 Mbps modes)
DS-SS method (in 11/5.5/2/1 Mbps modes)
Wireless channels
1 to 11ch (active scanning)
12ch, 13ch (passive scanning)*2
Frequency band
2.4GHz band (2.4 to 2.4835GHz)
*1: These communication modes are based on the theoretical communication rate in the standard
and thus do not match effective rates. Such factors as connected devices, radiowave environment,
surrounding obstacles, installation environment, usage status and used OS, applications and
software may affect communication rate and distance.
*2: It may take much time to connect US40a to a passive scanning channel.
