Texas Instruments has again been ranked at the top of the latest Vendor Matrix released by ABI Research.

Ember and Oki Semiconductor claimed the second and third spots in the company's most recent evaluation of worldwide IEEE 802.15.4 wireless sensor network IC vendors.

The Vendor Matrix is an analytical tool developed by ABI Research to provide a clear understanding of vendors' positions in specific markets.

ABI Research evaluates vendors on the basis of Innovation and Implementation by selecting multiple criteria related to product/company characteristics that serve as proxies for the vendors' performance in these two areas. Upon evaluation, vendors are assigned numerical scores that are aggregated and analyzed to provide overall rankings of each vendor on the Innovation and Implementation axes.

Specific to the evaluation of IEEE 802.15.4 IC vendors, relevant criteria included: whether the vendor had an SoC product offering, date of first product release, current product generation, transmit and receive power, receive sensitivity, and public/private status of vendor.
