Wireless Remote Control Using Simple Wireless Modules



Consumers want to go wireless and eliminate the clutter on their desks and equipment, but this means that many manufacturing engineers need to learn how the wireless world works. This often requires engineers to learn about all the fancy wireless protocols, complex RF propagation, and wireless standards. Some developers create their own proprietary wireless solutions, but it's not an easy task and there are many obstacles to consider. For example, wireless designs will certainly require in-depth RF knowledge for PCB design, routing, and impedance matching. The firmware can also be a challenging area as the designer must learn in-depth knowledge of the protocol stack to maintain inter-polarity with other systems, as well as reliability and maintaining data integrity. This usually requires a large team of engineers to design and manufacture the product. All of these tasks add development cost, and most importantly, delays the time the product can make it to market. Most designers would prefer to reduce product cost and release early.

If you wanted to leverage what the best wireless designers in the industry have made you could simply find a vendor that manufactures awireless adc module. For easy development, one of the best solutions is a wireless data transmission modulewhich will make interfacing with other signals really simple. Many high quality wireless modules allow circuit designers to use common interfaces like analog, digital, or serial I/O. Designers are familiar with these interfaces which makes development straight-forward. The signals are sampled on one wireless node and then regenerated at the other wireless node. Most high quality modules also use complex modulation techniques to avoid interference, and include the algorithms needed to ensure proper data integrity. This makes the system simple and transparent, working like a standard wired bus. More important than anything else, using awireless I/O modulesmeans that users can go wireless without the complex wireless design or certification.
