Incorporating wireless into your electronic product doesn’t have to be a daunting task, that is if you choose to use a rf data module instead of reinventing the wheel by making everything yourself. When going with a module, everything is taken care of, including all the complex wireless frequency modulation, tuning, filtering, amplifying, and decoding. There are many companies out there that specialize in creating wireless IO modules, so not reinventing the wheel means using one of their wireless products that’s been tested and used many for many existing applications. Doing so will save you a lot of hassle, time, and even cost. When making a selection for a wireless module, think about using a wireless transceiver module that include serial and analog and digital communication pins. There are many modules available, but keep in mind that not all modules are created equal. If you’re running on batteries, be sure to select a module that uses Zigbee. If you’re unfamiliar, Zigbee is a protocol that uses very low power for low bandwidth data transmission, but latencies can also be very quick.

Also, select a wireless transceiver chip that uses either DSSS or FHSS. DSSS refers to direct sequence which locks in on one channel, while the FHSS refers to frequency hopping. Both methods have their advantages, but when you reach the high-end modules they will typically use both methods. Using both DSSS combined with FHSS will offer several benefits, including lower power use, increased reliability, and less prone to radio interference. Selecting an off the shelf module will make your design easier, more powerful, and you won’t have to reinvent what’s been done well for so many years.
