In our most recent Embedded Market Survey 38% of respondents said they use wireless in their designs - this has been the same level for the last three years. Is there a reason it is not growing? While over 50% of those including it use WiFi which is steadily growing the biggest growth is inclusion of Bluetooth. What are you using and are ther any new protocols which should have a big future in embedded designs?

802.15.4 use is probably going to increase in embedded products due to the need to communicate with smart meters and appliances in the smart grid.

RFID, specifically NFC (13.56MHz near field) and UHF (couple of bands in the 868MHz to 928MHz range) is moving from the product ID and asset management area into more general use. The bump-and-exchange functions in some of the newer smart phones is an example of NFC. Wide adoption is still hampered by the need for a tranceiver IC (called a Reader). Wonder when the micro companies will embedd this? The digital is not more complex than a UART or USB I/F. Maybe the transmitter silicon requires too much space?
