Korea Telecom demonstrates LTE cat one for smart meters
December 15, 2015
Korea Telecom has demonstrated smart meter connectivity using ultra-low power LTE connectivity using technology from Israel-based chipset company Altair Semiconductor.
At last month’s KT Internet of Small Things event in South Korea, KT showed how Altair’s FourGee-1160 category one chipset could provide ultra-low power LTE connectivity for three IoT use cases.
“This Korea Telecom and Altair Semiconductor demonstration is designed to show how mature LTE cat one is, and to illustrate several typical use cases – among the many – that this IoT connectivity technology enables,” said Byungkyun Kim, vice president at Korea Telecom. “We partnered with Altair as they have the only cat-one chipset platform that is able to meet our aggressive power and feature requirements. We are looking forward to expanding the strategic collaboration with Altair as this technology commercialises.”
Claimed to be the first chipset designed and optimised exclusively for LTE cat-one operation, it features ultra-low power consumption, support for various typical host and peripheral interfaces, an embedded power management unit and a flexible application layer with hardware-based security. The chipset has been adopted by numerous M2M and IoT module and device makers and is expected to ship commercially by the end of this year.
“The versatility of the FourGee-1160’s architecture allows it to be used for a wide range of applications, such as these three that KT demonstrated at the event,” said Eran Eshed, co-founder of Altair. “At the same time, the common denominator is ultra-low power consumption, which today only Altair can offer in a cat-one chipset. Smart gas or water meters, for example, require up to a ten-year battery to make good business sense. The 1160 was built for exactly these kinds of applications.”
One unique feature of the chipset is power-save mode (PSM), which enables terminals to enter a deep-sleep mode for long periods of time after notifying the base station. This reduces significantly the amount of power associated with frequent communications requests normally sent by the base station. PSM is a crucial element of many IoT and M2M applications, including smart metering, smart city and telematics.
