Growth in the wireless electronics 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 engineers might desire to roll their own wireless solution, but be warned that it’s a tough task and their will be lots of things to consider. Good examples of challenges that are faced include high frequency PCB design, routing, and impedance matching. Another challenge involves the firmware which is necessary for the protocol communication stack, as well as algorithms to maintain data integrity and system reliability. To accomplish this, it often requires teams of engineers to design, manufacture, test, and certify the product. This means higher development cost, and increased time before the product hits the market. Companies would prefer to integrate wireless into their products at low cost and as quickly as possible.

Instead of creating your own wireless solution from scratch, the alternative is to find a company that manufactures a wireless RF module. For quick wireless development at reduced cost, one of the best routes is to use a wireless data transmission module which makes signal interfacing simple. Wireless modules allow designers to use common interfaces like analog, digital, or serial as signal inputs and outputs. Development with these common interfaces is easy since many engineers already know them well. The signals are sampled on one wireless node and then regenerated at the other wireless node. Most of the high-end wireless modules will use FHSS or DSSS modulation techniques to avoid interference and data integrity. This allows the designer to treat the wireless link like a regular wire. Most importantly, using a wireless analog modules means that companies can incorporate wireless into existing products quickly and effectively.
