BlinkSight & imec indoor GPS single-chip a first
BlinkSight, a fabless semiconductor company in real-time location systems (RTLS), has released the first single-chip "˜indoor GPS' solution for RTLS and wireless sensor network (WSN) applications.
Based on ultra-low power impulse radio technology by imec and Holst Centre, the new chip delivers real-time information to track and trace people and objects in indoor environments. Its unique combination of high accuracy, long range and low power consumption is ideal for both business and consumer applications.
"The real-time location business is emerging and the global market for connected devices is growing at tremendous speed," says BlinkSight CMO Guus Frericks. "Adding highly accurate indoor capabilities to connected devices such as smartphones paves the way for a broad range of game changing consumer applications across "˜Internet of Things' segments like smart homes, offices and retail."
BlinkSight's innovative system solution uses the ultra-low power "˜impulse-radio' (IR) developed by imec and Holst Centre which enables real-time 3D location information that is accurate to within 10 cm.
The device combines digital processing elements and sophisticated analogue radio functionality in a single chip, enabling superior performance at a low cost of ownership. It can operate in both the 3.1-4.8 GHz and 6-10 GHz bands for use around the world and seamless co-existence with other wireless technologies.
What's more, with an operating voltage range of 1.5 to 3.6 V, the new device is ideal for battery-powered applications. Together with its small form factor and low power consumption, this makes it suitable for integration into tags, wireless sensors, base stations and mobile devices. A base station equipped with BlinkSight's technology could track and trace thousands of fast moving tags in real time. In addition the tags are interactive and capable of sending dynamic data (e.g. temperature).
"Our solution is easy to install and thanks to the collaboration with imec we've been able to bring a working solution to market very fast," says BlinkSight CEO and founder Stéphane Mutz. "A lot of effort went into minimising power consumption, and we expect to have tags powered by energy harvesting available soon. We aim to bring a complete turnkey system to market and want to work with industry leaders to bring accurate indoor GPS capabilities to connected devices."
"Imec was a pioneer of impulse radio and the first to demonstrate an integrated impulse radio prototype. We are thrilled that BlinkSight is now successfully bringing the technology to market," says Harmke de Groot, Program Director Ultra-Low Power Wireless and DSP at Holst Centre/imec.
Fabricated using standard 90 nm RF-CMOS, the chip is manufactured at TSMC in Taiwan.
The device incorporates an embedded software programmable ultra low power 128 bit vector DSP ( less than 16 pJ / cycle). The range has a greater than 60m Line of Sight and over 20m No Line of Sight. The 3D positioning accuracy is better than 10cm and the device is claimed to operate for over 5 years using a standard coin battery.
