Communications: Collaborative Efforts Let Wi-Fi Chip Tag-Team With CDMA Or WCDMA

A collaboration between Atheros and Qualcomm will produce a low-power, high-performance chip set for cellular and wireless LAN-capable handsets and PDAs. Mobile devices based on the forthcoming chip sets will support CDMA and WCDMA technologies as well as 802.11g or 802.11a/g wireless LANs. Atheros will work to ensure the interoperability of its highly integrated single-chip Radio-on-Chip for Mobile (ROCm) with the MSM6550 CDMA2000 or MSM6280 WCDMA chip sets from Qualcomm. The combined chip sets will let cellphone manufacturers create phones that can seamlessly switch between cellular and Wi-Fi networks to minimize connection charges and provide better data connectivity. Samples of the chip sets are expected late in the second quarter.
