    Wi-Fi Alliance polishes HaLow for IoT connectivity

    January 6th, 2016

    The Wi-Fi Alliance is extending its support for the internet of things (IoT) market with a new brand name for products incorporating low power, long range IEEE 802.11ah technology. “Wi-Fi HaLow extends Wi-Fi into the 900 MHz band, enabling the low power connectivity necessary for applications including sensors and wearables,” the organization says. “Wi-Fi HaLow will enable a variety of new power-efficient use cases in the smart home, connected car, and digital healthcare, as well as industrial, retail, agriculture, and smart city environments.”

    Pay and display goes NFC

    November 21st, 2013

    Parking and transportation ticketing equipment supplier IEM is to bring NFC payments to an initial 1,000 solar powered ‘pay and display’ parking ticket machines in France, using UIC’s UIC680 low power payments module. Motorists will be able to pay for parking with a range of contactless cards or their NFC phone. Presto Pay NFC will then be gradually added to around 5,000 machines in other European countries, IEM’s Phillipe Menaud told NFC World.

    Advantages of the QCA1990 include support for smaller and cheaper NFC antennas, ultra-low power consumption, a small footprint and integration with a wide range of mobile phone processors, Qualcomm’s Neeraj Bhatia has told NFC World. More

    Circuit offers NFC security boost

    July 24th, 2012

    A memristor-based circuit that spits out a steady stream of true random numbers could hold the key to enhanced security in NFC transactions, reports IEEE Spectrum. The tiny circuit, invented by engineers at the National Tsing Hua University (NTHU) in Taiwan, offers the prospect of using small low power devices to generate true random numbers — something that is difficult to do using today’s digital circuits, which typically produce numbers that aren’t completely random, the publication explains.
