Save Time and Money with Secured Wireless Connections Worldwide Produced by: Westermo Teleindustri AB Photo: IStockphoto BildN, Västerås, Sweden Illustrations: Visual Information Sweden AB Eskilstuna, Sweden Printed by: Eskilstuna Offset AB Sweden 2007 Specifications are subject to change without notice due to continuous product development and improvement. The ability to create remote connections to equipment can provide companies great savings both in time and money.
The GSM-series: The natural choice for reliable GSM applications in harsh environments Westermo GSM-modems allow all kinds of serial equipment to communicate anywhere within the coverage of a GSM radio base transceiver station.

GSM (Global System for Mobile communication) Connection time between GSM modems is 4 – 8 seconds (using the V.110 protocol). GSM makes the wireless transfer of voice/text/images between different types of equipment possible, but only within the coverage area of a network operator's base transceiver station. It is possible to use GDW-11 / GD-01 on different operators networks and between different countries (Roaming).

The area covered by a base station is called a cell. The entire GSM network is organised with cells of varying sizes. A cell can cover areas with a radius of 200 metre (656 ft) up to areas with a radius of ~30 km (18.64 mi). This depends on where the base station is D2 located and the surrounding environment.
Circuit Switched Data A CSD connection makes it possible to transfer serial data at speeds from 300 bit/s up to 14.4 kbit/s depending on network providers. The table on the right side shows the available speeds and protocols. Data communication can be set up for transparent or non-transparent data transfer. RLP (Radio Link Protocol) is used in non-transparent transfer; this is an error corrected GSM protocol. This protocol creates a more reliable transfer, but also generates delays in the transfer.
GPRS GPRS is an extension of GSM network where packet switching data traffic is supported. With GPRS each channel that is not busy with call traffic is available for packet switching data traffic. Packets from several different users can be mixed within the same channel, which results in efficient sharing of available network resources. GPRS permits even higher transfer rates as it uses several time slots for the transfer. In theory rates of up to 115.
The problem occurs when a unit, for example, a computer wants to communicate with peripheral equipment and the computer generates the connections. No one knows the IP-address that the computer should connect to, GPRS as these are assigned dynamically. The same problem occurs when two devices need to communicate and none of them are master. The modem cannot initiate IP-communication, as it does not know which IP-address will be assigned.
Antennas A whip antenna is the most common example of a monopole antenna, an antenna with a single driven element and a ground plane. The whip antenna radiate equally in all directions in a horizontal plane, although they have a conical blind zone directly above them. A whip antenna is not to be recommended in public installations. It could be more suitable to mount a more discreet antenna, which is not so easy to break or to be vandalised (Low profile).
