Hybrid phone network offers Wi-Fi calls

Smartphones let you do almost everything over Wi-Fi, so why do we still have to use up cellular minutes when making a call? That’s the thinking behind Republic Wireless, a new hybrid phone network that lets you seamlessly make calls using any available Wi-Fi hotspot, falling back to the regular cellular network when you move out of Wi-Fi range. The company ...

‘Transition away from quartz oscillators has begun’ – IDT

Integrated Device Technology is claiming a breakthrough in accuracy for CMOS oscillators with its first device to show ±50 ppm frequency accuracy. The chip firm sees a move away from traditional quartz crystal-based timing circuits driven by the search for power reduction CMOS-based devices can offer power and cost savings in replacing traditional quartz crystal-based oscillators. “The transition away from quartz-based oscillators has begun,” said Fred Zust, ...

EM Microelectronic, the chip arm of Swatch, has announced the Bluetooth V4.0 qualification of its EM9301 0.8V transceiver. The IC is a single-mode master/slave controller providing Bluetooth low energy function from the radio up to the host controller interface (HCI), optimised for low voltage and low energy systems such as wireless sensors, remote controls and monitoring. “With operating supply voltage ...

Wireless network measures your breathing

It’s not easy sleeping with tubes up your nose, but when doctors want to monitor a person’s breathing they have few other choices. A new wireless system promises to do away with intrusive medical technology – but instead it might end up being used as a surveillance tool to track people’s movements and activities behind closed doors. While testing some ...
