RF Modem I/O Module for RS232 Wireless
Wireless design can be very challenging. When creating a wireless RF modem engineers have to choose between going with an off-the shelf module solution or if they should design the system from scratch using modulators, filters, and amplifiers. It’s important that engineers know that designing a proprietary solution involves many complex steps, and systems must be certified by the FCC or ESTI in Europe. Since high frequencies behave differently in the Ghz range, impedance matching is very important and will be difficult even for experienced 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 module can offer many benefits over designing a system with low-level components and attempting to pass regulatory approvals. Wireless modules offer much faster time to market, and allow designers to incorporate wireless into their products with ease. Wireless modules integrate both the complex wireless radio hardware and the software to ensure a reliable system. The thought behind these modules is to get rid of the frustration with complex wireless development, and allow the designer concentrate on more important aspects for launching a fresh product. Some radio modules are even designed to be simple drop in solutions that can easily replace existing wired installations. These modules can wirelessly transmit digital, analog, or even serial data signals. Most wireless i/o modules will require no configuration and work right out of the box. These wireless modules are called wireless cable replacements and can be treated as a regular wire. These wireless modules are usually already FCC and ESTI approved, and allow designers to bypass further testing for their wireless design. There are many more benefits that wireless modules can provide, but most importantly modules for rs232 wireless open a door to new applications that could not be developed before.
