8 Experts on Overcoming Challenges of RF Solution Design 15 are in the world, due to the increasing number of wireless devices in a given frequency band. The easiest way to address many of these challenges is to use a wireless module. Wireless modules are often ready-made, functional, complete RF transceivers that require only connections to the antenna, power, ground, and data. Organizations that are not conversant with RF technology or do not have an RF engineering team may prefer to use a wireless module. Another advantage of wireless modules and chips is that many manufacturers provide a development kit that supports several module types. These kits often come with a common microcontroller on a board and an example program so that you can get started quickly, saving software development time. Many wireless modules today come pre-certified for many countries and regions, allowing the developer of the product to skip costly certification testing and inherit the certification that comes with the wireless module. In addition to wireless modules, highly integrated wireless chips are also available for designers who want to design their own basic RF hardware. These integrated circuits generally need power, ground, data, and antenna connections within your own printed circuit board (PCB) design. They will be controlled via your own application within a microcontroller on your PCB. Alternatively, many wireless chips are integrated into a system-on-chip (SoC) that includes the RF section and a microcontroller in one package. You simply put the chip on the board and it performs all the processing, control, and RF functions. When using wireless modules, you must make a few important decisions. First, you must select the right frequency for your application. The frequency you choose depends on factors such as range requirements, data, and where the device will be operating. Second, you must decide whether you want licensed or license-free operations. Finally, for some products, component longevity is an important consideration.
