If you are an OEM or product designer you know that in any given design there can be hundreds of critical engineering decisions that need to be made. For example, I want to add wireless to my product and have a smart phone interface.
How do I add wireless connectivity?
What are the tradeoffs?
Should I use Wifi or Bluetooth or BLE Smart or NFC?
What silicon do I use, Microchip, NXP, Cypress, Bluegiga?
Where do I start?
First ask some questions:
What is the use case you are trying to achieve? ..this tells you Wifi Bluetooth etc
What are your annual volumes? ..this tells you chip down or module
What is my critical path to market and missed opportunity costs in delaying?
