NOTE:
Auto-negotiation of data throughput and Ethernet operating speed depend on the connected device
being set to auto-negotiate as well.
5.4 ANTENNASFORCONNECTIONTO900‐MHzMODULES
Like the 2.4-, 5.2-, 5.4-, and 5.7-GHz module, the 900-MHz connectorized module has
◦ the same housing.
◦ a covered Ethernet port.
◦ a utility port for alignment headset, sync cable to CMM2, or override plug.
The 900-MHz AP or SM is available either
◦ as a connectorized unit with a 16-inch (approximately 40-cm) cable with a male
N-type connector for connection to the antenna.
◦ with an integrated horizontally-polarized antenna in a different form factor.
5.4.1 CertifiedConnectorizedFlatPanelAntennas
Last Mile Gear has certified four connectorized flat panel antenna options. Last Mile Gear
resells one of these, whose attributes include
• gain—10 dBi
• dimensions—8.8 x 8.1 x 1.6 inches (22.4 x 20.6 x 4.06 cm)
• weight—1.2 lbs (0.54 kg)
