DESCRIPTION
ME4―2409
ME4 with (1) 2.4 GHz 802.11g and (1) 4.9 GHz 802.11a radio modules.
ME4―2450
ME4 with (1) 2.4 GHz 802.11g and (1) 5 GHz 802.11a radio modules.
ME4―2450R
ME4 with (1) 2.4 GHz 802.11n and (1) 5 GHz 802.11n radio modules.
ME4―5050S
ME4 with (2) 2.4 GHz 802.11g radio modules.
ME4―2449
ME4 with (1) 2.4 GHz 802.11g and (1) 900 MHz 802.11g radio modules.
ME4―2424
ME4 with (2) 5 GHz 802.11n radio modules.
Custom radio configurations are available upon request. May include a mix of licensed, military or unlicensed frequencies.
802.11g and 802.11a radio modules use one antenna port per module. 802.11n radio modules use two antenna ports per module in multiple-input
and multiple-output (MIMO) mode.
For 802.11n modules, the Max. RF Transmit Power specification is for the combined power output of the two antenna ports.
