Long Battery Life Driven by Ultra Low Power Transceiver in Wireless Headset

12/10/2002 - The most important issue in wireless consumer products is battery life; ideally all portable products would have a long battery life so that charging the product is kept to a minimum. The new ultra low-power wireless headset from Atoz utilizes XEMICS' ultra low power technology to provide a wireless headset solution giving complete freedom of movement for up to 100 hours of use between charges.

Explaining why they chose XEMICS ICs, Phil Chen from Atoz said "The key point is XEMICS has ultra low power technology as well as mature know-how in transceiver techniques. So we think it's the best solution for long battery life, to have a XEMICS' transceiver in our product". XEMICS' Ultra low power consumption transceiver helps ensure that the Atoz wireless headset doesn't need a special battery, additionally saving money.

Phil Chen also commented on the good sales and marketing support as well as the technical support available from XEMICS, "who can provide some helpful design services especially in RF design/RF consultation".

The Atoz EZPhone wireless headset is compatible with all kinds of mobile phones, with consistently good audio quality. Long talk time and standby time are ensured through the headsets ultra low power consumption.

The EZPhone Wireless Headset incorporates XEMICS' XE1201A ultra low power RF transceiver. The design was derived from the XM1201A reference module for the RF front-end design and includes a 16bit microcontroller, an ADC, a DAC, amplifiers and power regulators. A perceived full duplex audio link between the cell phone and the ear piece covers a distance of 3 to 5 meter for an average current consumption during operation of 12mA measured at 3.6V.

With a talk time of 5 hours and a standby time of up to 100 hours the EZPhone takes full advantage of the XE1201A's low power functionality. The dongle base and the headset are assigned a unique ID as a pair to provide a secure communication link.

Atoz Communication, was established in 1984, as a specialized designer and manufacturer of professional laptop computers. Due to the popularity of wireless communications and fast widespread of consumer electronic products, Atoz moved from pure IT business to wireless communication 2 years ago. In order to keep state-of-the-art R&D capability and develop next-generation products, Atoz established R&D centres in Europe, China, and Taiwan. Through strategic alliances and technology exchanges with some leading companies, Atoz vision is to become one of the leading companies in wireless communication innovation. www.atoz.com.tw
