Thanks to a combination of STMicroelectronics and iSuppli for this one which takes account of the new look to the market since ST and NXP pooled their wireless chip operations into a $3 billion revenue joint venture taking the No.3 slot in the wireless industry's rankings. That deal is expected to close in Q308. Assuming it does, here, with their market shares of the total market, are the wireless chip company rankings:
Qualcomm 22
TI 18
ST-NXP 14
Mediatek/ADI 6
Infineon/Agere 5.5
Freescale 5
Broadcom 2.4
