Restructuring Bluetooth for mobile useThe trend of integrating Bluetooth as a key component in cellphones is nothing new. Most handset makers today list Bluetooth as one of the most product salient points.
More countries are rolling out legislation to enforce drivers to use handsfree kits or headsets. Bluetooth presents the ideal wire-free solution to this. Hence, more and more handsets must include Bluetooth technology. Wearing a Bluetooth headset while walking around town is increasingly acceptable—this is boosting Bluetooth’s attach rate in phones. The attach rate continues to increase year on year, with more headsets supplied in the box (”bundling”), and with mobile handsets helping operators and handset vendors differentiate their products.
While the trends of integrating Bluetooth and other technologies (mobile TV, FM and GPS) continue to put phone manufacturers under increasing pressure, certain design pressures remain constant. Users will not tolerate large handsets, compromised performance, and shortened battery life due to power-hungry technologies. These present a tough design challenge for the handset maker. In turn, the handset maker is forced to demand the best from its component suppliers. This article looks at the steps that Bluetooth chip vendors are taking to address these issues.
