Wireless Digital or Analog I/O Cable Replacement
Electronics designers sometimes decide they need wireless digital or analog I/O, and then need to decide between using available modules or design a wireless system from scratch with filters, modulators, and oscillators. There are many crucial factors to consider before making the decision, and one must be aware of the challenges in these designs, and the strict regulatory approvals required.
Complex engineering tasks such as circuit board layout and impedance matching are very important, which will be challenging even for experienced electrical engineers. Not only are the challenges technical, but governmental certifications can take many months to pass, which inevitably delay the product to market. A wireless I/O modem can bring many advantages to both engineers and companies over designing a system from scratch. Wireless modules allow companies to reach the market more quickly, and reduce frustration and cost for engineers. Wireless modules usually incorporate all the complex software or firmware to maintain data integrity, such as checksums and error handling, as well as high frequency board design.
The general idea for using wireless modules is to reduce design frustration and allow companies to focus on other aspects of the new product. Some wireless modules offer simple drop-in networking where users can replace existing cables or wires with ease. These modules can transfer analog, digital, or even wireless serial signals. The best wireless modems 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 regulatory certified, allowing engineers to bypass further testing for their wireless design. All of these benefits can allow the product to incorporate the power of wireless without the complex understanding or frustration of reinventing the wheel.
