Wireless Modem Transceiver Module for RS232
Friday, September 3rd, 2010When going for a wireless modem system companies must determine whether to manufacture a proprietary radio, or use an off the shelf solution. Designing a wireless system from scratch should be a careful decision, as it requires many complex steps and government certification. PCB design for high frequencies can be very difficult, and for important designs it should only be undertaken by experienced engineers. Aside from challenges with design, companies must certify proprietary wireless systems with the FCC which can take months to years.
A transceiver module can provide several other benefits of designing a wireless system from scratch. Wireless modules allow companies to finish a wireless product much more quickly, and at a much lower cost. Wireless modules integrate both the complex wireless radio hardware and the software to ensure a reliable system. The general principle of these modules is to reduce the frustration with complex wireless development, allowing companies to focus on the bottom line for a new product. Some transceiver modules are even designed to be simple drop in solutions that can easily replace existing wired installations. These modules can wirelessly transmit digital, analog, or even serial data signals. Many wireless rs232 modules don’t need any programming or configuration and work straight out of the box. These transceivers are usually called wireless cable replacement solutions and can be used like a standard wire. These wireless modules are often already FCC and ESTI certified, allowing engineers to bypass further testing for their wireless design. All of these advantages reduce frustration, cost, and time in developing new wireless products.
