Low-power GPS for IoT

Low-power GPS for IoT

The Internet of Things (IoT) continues its rapid roll-out across much of the globe. Geolocation and indoor positioning have become among the IoT’s most-used features. NextWave demos low-power GPS for IoT at Mobile World Congress.

The forecast says that by 2020, 5 billion devices will rely on geodata to support a wide variety of applications. With the proliferation of the Internet of Things (IoT) devices out there, the challenges still remain. IoT devices require small batteries that can supply power for 10 years or more. And current GPS solutions are particularly power hungry. In addition, GPS fails to operate reliably indoors or in dense urban environments.

The main barriers for accurate 4G-based positioning have been,

  • Inaccurate antenna databases
  • Non-synchronized networks
  • Distortions due to NonLine-of-Sight (NLOS)
  • Radio propagation
  • High power consumption.

Inexpensive GPS

With traditional GPS solutions not suitable for inexpensive, battery-powered IoT devices, that’s where Nestwave SAS comes in. The Paris-based startup has developed a geolocation solution that reduces power by more than 10X, eliminates dedicated geo-positioning chips, and improves dense urban and indoor coverage. It holds 10 patent applications.

Nestwave has developed an ultra-low power, advanced GNSS solution for use in internet of things (IoT) applications.

The software-based GNSS solution allows modem customers to add accurate position-based services to their modem platforms.

When integrated with an IoT modem such as NB-IoT, Cat M1, LoRa or Sigfox, the solution offers low-cost geolocation for emerging applications such as asset tracking, smart factories, and smart cities, without the need for an external GNSS chip.

From the CEO’s desk

“After several years of development and based on a number of key signal processing breakthroughs, we believe Nestwave is well-positioned to provide a best-in-class solution for low-power IoT applications where position awareness is key,” said Rabih Chrabieh, Nestwave CEO. “We are excited to demonstrate our GPS solution, in collaboration with Cadence by leveraging their Tensilica Fusion F1 DSP platform at MWC this year.”

“The Fusion F1 DSP is gaining traction with customers as a platform for low-cost, power-sensitive IoT communications standards like NB-IoT,” said Gerard Andrews, director of marketing for Tensilica products at Cadence.

It requires a single processor core that is proficient at both DSP and control-code workloads.

The Fusion F1 DSP excel at “always-on” processing, including wake-on-voice and sensor fusion applications. It has a highly configurable architecture.

Additionally, the Fusion F1 DSP instruction-set architecture is very efficient at running narrowband wireless communications standards like BLE, Thread, Zigbee, 802.11ah, NB-IoT, and GNSS.
