iPod uses 2,4 GHz transceivers

16 May 2007 Telecoms, Datacoms, Wireless, IoT

Swiss consumer electronics specialist Zicplay has specified a pair of ultra-low power Nordic Semiconductor nRF24L01 transceivers for each of its EWOO iPod wireless remote control and docking stations.

The 60 gram, shirt pocket-sized EWOO includes a large 1,8" LCD screen, intuitive circular navigation and scroll wheel, and access to all the menu, song, artist and playlist (etc) functionality and organisation that is on the iPod itself.

The EWOO comprises a dock that can house and charge both the EWOO and any iPod via a Dock Connector plus the actual remote controller. An optional USB dongle further allows users to remotely control an iTunes library on their computer. At the back of the dock is an analog and digital (optical) audio line out plus a video line out (S-video) for users to connect to their home AV equipment and/or computer.

The wireless control is based on a matched pair of nRF24L01 ultra-low power 2 Mbps, 2,4 GHz proprietary transceivers - one in the remote and one in the iPod docking unit. These underpin the 2-way radio communications required for accessing a live iTunes library's content and menu structure stored on the user's iPod or computer.

"Although we did consider using standard 2,4 GHz technologies - including Bluetooth, ZigBee and Wi-Fi - none matched the Nordic's proprietary solution for power consumption, bandwidth and overall implementation cost," stated Alexandre Colot, CTO at Zicplay. "The nRF24L01 consumes about three times less than the power consumed by the 'low power' LCD screen in our application and the nRF24L01 also absorbs so much of the RF design complexity that it requires only a low cost 8-bit MCU to support it. This has all helped us to build a high value handset that weighs just 60 grams, yet will still run for up to 10 days between recharges."
