WiFi

Understanding

The internal WiFi module has FCC modular approval and may only be used with one of the GE MDS

approved antennas (see 802.11 WiFi Module Specifications below). The WiFi antenna is connected to the

reverse-SMA connector on the unit’s front panel. Only these antennas may be used. The WiFi module can

be configured to operate as an 802.11b/g/n Access Point or Station. The operational mode and frequency

can be configured through the user interface.

The specifications for the 2.4 GHz WiFi module are as follows:

• Protocol: IEEE 802.11b/g/n OFDM 6 to 54Mbps, CCK 1 to 11Mbps

• Frequency Range: 2400 to 2500 MHz

• Maximum Transmit Power: 18 dBm (Default is 15 dBm)

• Permissible Antennas:

- GE MDS 97-4278A36

- GE MDS 97-4278A34

- GE MDS 97-4278A35

• FCC: Part 15C

• FCC ID: VRA-SG9011028

• WiFi Antenna Connector: Female Reverse SMA

The unit supports the following WiFi security modes:

None (should be used only to test connectivity)

WPA2 + CCMP/AES Encryption – This mode should be used if all client devices support WPA2/CCMP.

Encryption + TKIP Encryption – This mode should be used if there is mix of both legacy client devices

that only support WPA/TKIP and newer devices that support WPA2/CCMP.

Also, WPA and WPA2 can be configured further in following modes:

•

Personal – This uses pre-shared keys (passphrases) configured on the MCR and client devices.

•

Enterprise – This supports EAP-TLS based authentication of client devices (configured with certif-

icates/keys) via RADIUS.

The default SSID is based on the unit's serial number, and takes the form of:

GEMDS_<SERNUM> (the serial

number is printed on the chassis sticker). The default password for WiFi operation is

GEMDS_ORBIT.
