During the 8th Annual International IC-China Conference & Exhibition (IIC-China) in 2003, technical experts from Texas Instruments and Philips Semiconductors communicated through their respective solutions to solve Bluetooth and WLAN coexistence interference problems. Since then, other companies have been trying to solve this issue. And with the growing number of applications supporting Bluetooth and WLAN, it is crucial to remove all interference in Bluetooth and WLAN's coexistence environment.

At this year's IIC-China event in Shanghai, Philips showcased its Bluetooth and WLAN coexistence schemes.

"Previously, Bluetooth and WLAN coexisted in different and separate devices such as notebooks and Bluetooth earphones," said Zhuang Shao-Yang, Philips' consumer and multimedia application marketing business manager for Asia. "But with the increase of WLAN cellphones, it is important to figure out the coexistence interference in Bluetooth and WLAN chips packaged in the same device."

Philips disclosed that they used four data lines to connect Bluetooth and WLAN chips based on packet transformation arbitration (PTA) rules so as to accomplish advanced frequency hopping (AFH) file PTA.

In-Stat senior analyst Brian O' Rourke commented, "We predict that by 2008, up to 58 percent of sold mobile phones will include a Bluetooth connection. It is essential for Bluetooth and WLAN to live together in next generation mobile handset."
