the serial interface across the cellular network to IP-based protocols, so that sensing,
mechanical, and control devices can report to Internet computers.
For those who only need quick and reliable Internet access, the gateway is ready to use
right out of the box. For users with more complex requirements, the gateway offers both
Web-based, SNMP and Command Line Interface configuration tools.
By uniting three networking media—Ethernet, serial, and cellular—the gateway can provide
Internet access to embedded products that are difficult to network with conventional wired
solutions. Equipment that generates Ethernet or serial data can communicate with
computers on the Internet by making a data connection to the cellular service provider. The
gateway does not interpret serial data, thereby eliminating the need to modify legacy
products to allow them to leverage its features.
Cellular access standards
The Cellular Gateway comes in three different models; identified in the table below. Different
cellular service providers employ different access standards for carrying data over the
cellular network. Your choice of gateway depends on the service provider you have chosen.
The CGW101 and CGW102 contain an internal radio.
The CGW103 requires an additional PCMCIA/PC Card that can be either GPRS or CDMA
1.x. The list of supported PC Cards are shown in the CGW103 row.
Installation depends on the model and is covered in
