When looking at Wi-Fi modules in the market, there are really three types of methodologies that users can classify or position. There is the transceiver-only module, which is typical to something that is found in a cellphone. There is a host microprocessor as well as a separate transceiver which requires designers have hardware and software expertise at the TCP/IP level. At the other end of the spectrum, there is the WiFi and custom application where the end product has everything onboard. There is no external microcontroller. In that case, the microcontroller obviously must have full, open capabilities to be able to customize the software. Again, designers have to have some knowledge of and capabilities with the stacks and the APIs. ST's approach falls in the middle. They provide a transceiver plus stack type of a module. So on the module there is the full, embedded Wi-Fi/TCP/IP layer for a stack, which allows designers to not require the engineer—it does not require any Wi-Fi expertise or any RF expertise for that matter. It has the best tradeoff when it comes to time to market and the ease of design-in for the customer. This allows for the best balance for a wide range of customer applications, allowing scalability with an external microcontroller.
