Cirronet SEM2410 Industrial Ethernet Bridge

The SEM2410 is the latest in high speed/long range wireless networking products from
CIRRONET, the established leader in spread spectrum wireless products since 1987. The SEM products are
designed to provide high speed wireless connectivity between ethernet devices. Typical uses include
ethernet bridging, SCADA networks, PLC networking and other industrial automation or
data collection applications.

For example, the SEM2410 can function as a high speed bridge between two ethernet networks.
SEM products can also provide wireless connectivity between an ethernet base station and multiple ethernet remote modems. Highly complex networks can be achieved using repeaters to extend range and coverage.
SEM products utilize CIRRONET’s third generation proprietary frequency hopping technology.
SEM products offer extraordinary data throughput combined with outstanding range, coverage, and link reliability.
The SEM2410 offers 230 Kbps of real data throughput, either point-to-point, or multi-point. The SEM2420 doubles that to
a total of 460 Kbps total throughput, four times the rate of typical RS-232 modems.Both products ensure errorless data via CRC error
checking and ARQ (automatic retransmission of errored packets). The SEM products can operate easily in extended range
applications - the FCC allows up to 400W EIRP for 2.4 GHz pointpoint radio links (see 2.4 GHz versus 900 MHz).
