1.2.1 Features
•
ADB model allows 700/800 MHz automatic band and bandwidth switching capability during
roaming.
•
Parallel Decode™ (PD) technology featuring dual receivers for added decode sensitivity in multi-
path and fading environments.
•
Native IP mobile model having “Stateless Data Compression” and “Protocol Reduction”, that
works with TCP/IP and UDP, uses standard 10/100 BaseT Ethernet RJ-45, and automatic MDIX
to get the most efficient use of user available bandwidth without requiring a dedicated server or
gateway. It acts as a router, interfaces with any Ethernet device or Native TCP/IP application, and
has two RS-232 ports that can be configured as terminal servers. Using an in-car hub or switch
makes adding other peripherals, such as a camera, possible.
•
Sophisticated DSP-based modem design provides added system performance, fewer retries and
more effective throughput.

•
Built as a one-piece integrated design in a rugged die-cast aluminum chassis.
•
GeminiG3 units automatically adapt to the speed of the base station for maximum network
flexibility.
•
Built–in, up to 32 channels, synthesized half-duplex operating transceiver with automatic
channel selection for improved roaming capabilities
•
AES 128-bit encryption ensures that both data and network remain secure.
•
Internal 12-channel WAAS capable GPS receiver. Out-of-band (OOB) signaling enables
transmission of GPS reports with no effect on system throughput. AAVL enables periodic
OOB reports based on time or distance.
•
Embedded Web server provides browser access for status and configuration of network pa-
rameters. Additionally, for ease of maintenance or upgrades, all unit firmware can be re-
programmed over-the-air.
•
Diagnostics combined with the Dataradio optional SNMP-based Network Management Sys-
tem (NMS) package, gives network administrators a proactive tool to collect and analyze di-
agnostic information.
