With more and more phone users switching to DSL or cable networks and using mobile phones instead of landline phones, there is a growing scarcity of fixed telephone lines that are compatible with conventional analogue modems. To  remedy this situation, eDevice has developed the WireX machine-to-machine wireless communication converter, which it claims is the first mass-market communication converter for machine-to-machine links. According to eDevice, installation is easy and users with a data volume of 1 MB per month can reduce their communication costs by more than 50% by switching from a dedicated phone line to WireX.

 

The WireX converter allows legacy equipment with embedded analogue modems to be communicate using a mobile telephone network (GSM or GPRS) instead of the conventional telephone system. It is designed for to be installed directly by the end user and does not require any changes to the existing legacy device; the user only needs to disconnect the phone cable from the wall and plug it into the WireX adapter. The data previously transferred over the phone link is then automatically transmitted over a GSM or GPRS network using phone line emulation.

 

In the home environment, WireX can be used with various types of existing devices equipped with analogue modems, including remote patient monitors, telecardiology monitors, alarm and security systems, and TV set-top boxes. In a SOHO or small business environment, it can be used to convert point-of-sale equipment, energy metering systems, and security and access control devices to wireless communication.

The Radiocrafts RC1180-KNX RF transceiver module is a compact surface-mount, high performance wireless communication module with embedded KNX RF protocol complying with the KNX-RF (Konnex over RF) standard of the KNX Association. The module has a UART interface for serial communication and configuration. It is pre-certified for operation under the European radio regulations for license-free use and measures only 12.7 x 25.4 x 3.3 mm with shielding. When used with a quarter-wave antenna, a line-of-sight range of 500 to 600 metres can be achieved. Operating in the 868 MHz frequency band, the RC1180-KNX meets the KNX specification and supports S, A and E modes. The physical layer complies with the relevant parts of the EN 50090 (ISO/IEC 14543-3) standard. KNX is the only open international standard for home and building control. The RC1180-KNF module can be used in smart home, building automation and building management systems, HVAC systems, automatic meter applications, and twisted-pair KNX gateways. The embedded protocol supports KNX-RF 1.1 and KNX Ready and can be used with unidirectional and bidirectional devices as well as battery operated systems.

The module supports bind of up to 64 other KNX-RF devices and uses
