Advancing a Wireless World Using Wireless RS232 Modules
July 25th, 2010 by admin
Growth in the rf telemetry field is expanding quickly, yet many electronics designers aren’t sure how to port their existing system to wireless. This can be a big step for engineers since it requires learning about common wireless standards and protocols, and about complex RF propagation. Some developers may decide to create their own proprietary wireless protocols, but it can be very challenging and there are many factors to consider. For example, wireless designs often require complex RF knowledge for PCB design such as impedance matching for high frequency design. On top of that, engineers need to know about the software for their own protocol which will maintain reliability and not interfere with other wireless systems. More often than not, you’ll need a big team of engineers to design, test, certify, and manufacture the product. This leads to higher development cost, as well as delayed time to market. Most designers would prefer to release as early as possible and keep costs low.
The alternative to creating your own solution is to take advantage of one of the many vendors that manufacture wireless I/O modules. For easy development, one of the best solutions is a wireless data acquisition module which makes connecting other signals from your system really easy. The best wireless modules will allow the designer to use common interfaces to speak with the modules, including direct analog or digital I/O. All designers of circuits are familiar with these interfaces which makes development easy. The analog, digital, and serial I/O are sampled at one wireless rs232 modules and then regenerated on another. Most high quality modules also use complex modulation techniques to avoid interference, and include the algorithms needed to ensure proper data integrity. This makes wireless transparent, so that the designer doesn’t have to worry about how the data gets across. Best of all, going with a wireless i/o modules means that users can go wireless without the complex wireless design or certification.
