Wireless Transceiver Modules

Before the birth of wireless transceiver modules, a designer may choose to use RF integrated circuits (chips or chipsets). As the finished desgins have to also pass rigid regulatory testing for distribution around the world, this task is tedious and long. This could take months or even years of a series of rejection and reworking until the product passed is approved.

Wireless transceiver (transmitter/receiver) modules are a faster time-to-market alternate to chip or chipsets that allow designers at all levels of RF experiece to combine a comprehensive wireless system into their products. Numerous of these transceiver modules are fabricated as a drop-in solution where designers make a fitting pin-out on their processor board and provide serial data to the appropriate pins. There are also modules that offer the easiest integration which allow the designer to send raw UART data into the module and expect the same data out on the receiving end of the wireless network.

Since wireless transceiver modules are approved by FCC and other regulatory agencies, designers using FCC approved modules bypass further testing for their wireless products, allowing quickest time-to-market alternative. Pre-approved modules by ETSI and other regulatory bodies allow the designers to deploy their products around the world with minimal additional approvals. This makes transceiver modules a standard option for designers in this fast-paced world of wireless information.

There are numerous fiber optic suppliers that offer a line of wireless transceiver modules that meet many of the performance and ease of use requirements of FCC. integrating these wireless data communicatioin solutions is as easy as transmitting information from a common port, communicating at a short or long range while utilizing low power and maintaining high levels of interference rejection over multiple kinds of networks.

Wireless transceiver modules are designed for different purposes. One kind is a frequency-hopping spread spectrum transceiver module that uses a simple UART interface to communicate with the host system. Some use a proprietary filtering technology to provide interference immunity, including 70 dB of cell phone and pager rejection.

There are still different kinds of transceiver modules that support more port types and meet the standard industry requirements specified by FCC and other regulatory bodies. Along with the different kinds are different brands like Cisco XENPAK and HP SFP to suit your preference. The bottom line is wireless transceiver modules offer a reliable, robust wireless method to transmit serial data, whatever kind or brand of transceiver module it may be.
