OPERATING CHANNELS
Channel availability depends on local country regulations. Wireless LAN system administrator must choose correct country
of operation. Channels are then automatically configured to comply with specified country’s regulations.
OPERATING RANGE
IEEE 802.11a:
up to 50 meters (164 ft) transmit and receive
IEEE 802.11b/g
up to 100 meters (328 ft) transmit and receive
DIVERSITY ANTENNAS
Two external dual-band 2.4-2.48/5.15-5.825 GHz, 2dBi omni-directional antennas
Additional optional antennas are also available on the 3750
Two internal (integrated) dual-band 2.4-
2.48/5.15-5.825 GHz, 2dBi
omnidirectional antennas
TRANSMIT POWER SETTINGS
Power settings for the US, in accordance with FCC regulations, are shown first below. In Europe, the Middle East, and
many other countries the output power level is further restricted and these limits are shown between the {} symbols. The
product will not exceed these output limits whenever such regulatory restrictions apply.
