Aaxeon Technologies has released their newest model in their Airolinx line of Industrial Wireless products. The APN-300N model builds upon their APN-200(802.11b/g) and APN-200A (802.11a/b/g) models, and includes the 802.11n Wi-Fi standard to provide up to 300 Mbps throughput.
IEEE 802.11n builds on to the previous 802.11 standards by adding multiple-input multiple-output (MIMO) and 40 MHz channels to the physical (PHY) layer, and frame aggregation to the MAC layer.
MIMO is a technology which uses multiple antennas to coherently resolve more information than is possible using a single antenna. Two benefits this technology delivers to the 802.11n Wi-Fi standard are antenna diversity and spatial multiplexing. The APN-300N model has a MIMO radio with two antennas, and is therefore able to support the 2T2R technology (2 Transmit, 2 Receive).
The APN-300N supports both the 2.4GHz and 5GHz band, selectable via the web interface. It will also contain an independent radio option where the customer can use the 5GHz radio for a backhaul and the 2.4GHz radio for a local connection.
The APN-300N supports the advanced security of WEP / WPA/ WPA-PSK (TKIP, AES) / WPA2 / WPA2-PSK (TKIP, AES) / 802.1x / RADIUS. Like the APN-200, the unit has two LAN ports that allow the unit to operate as a two port switch. Additionally, it supports STP and has a standard operating temperature of range of -10C to 60C.
Aaxeon will also offer an extended temperature model that has an operating range of -35C to 75C. The APN-300N will be available to ship in Q3 of 2012.
