Sigfox, a startup based near Toulouse, France, hopes to raise more than $70 million to build a national network in the US for the Internet of Things. SigFox picked the Bay Area to demonstrate their IoT wireless network that promises to link anything to the Internet, from smoke detectors to dog collars and bicycle locks.
Sigfox will cover the San Francisco peninsula, from its urban tip to Silicon Valley, some 40 miles to the south. It will use the unlicensed 915-megahertz spectrum to provide connectivity. Sigfox hopes to close funding early next year. Sigfox technology already covers the whole of France, most of the Netherlands, and parts of Russia and Spain.
They now cover 420,000 square miles in Europe with ranges that run from a couple of kilometers for underground water meters to 500 km for connected billboards run by Clear Channel.
Four companies now make Sigfox base stations using 800-900MHz transceivers. The base stations can run for 5-20 years on batteries, but are limited to data rates of 100-600 bits/second, sending a maximum of 140, 12-byte messages a day and receiving no more than four eight-byte messages a day. Sigfox charges operators a subscription rate of $1-16 a year per node based on volume. That’s a fraction of the $1-2/day a cellular link would cost, said Castonguay of Machina Research.
It also has an unnamed partner with whom it hopes to put base stations on satellites for a future IoT network with global coverage.
Around the world cities are beginning to deploy a diversity of M2M sensors to improve the efficiency of transport, lighting, irrigation and refuse collection.
The upcoming .11ah standard, using the 900 MHz band, is expected to cover many home uses at 10-20 Mbits/s. It will also help WiFi vendors extend into large building networks supporting up to 8,000 connections. Chips are expected to hit the market starting in 2015. NEC is the first company to deploy the new oneM2M service layer standard in a live smart city control center.
The Sigfox standard is proprietary. Competitors include the Z-Wave Alliance, a consortium of leading companies in the home technology space and operates in the sub-1GHz band. It supports data rates up to 100kbps, with AES125 encryption, IPV6, and multi-channel operation. Z-Wave utilizes a mesh network architecture, and can begin with a single controllable device and a controller. Additional devices can be added at any time.
Intel, Broadcom, Samsung, Dell, Atmel and others have joined forces to launch the Open Interconnect Consortium. The intention of the OIC is to create specifications for interoperability. It will encapsulate various wireless standards to enable secure device discovery and connectivity across different devices.
Apple and Google, two of the biggest players in the Internet of Things market, may go their own way.
Google acquired smart thermostat company Nest for $3.2 billion and WiFi-enabled camera company Dropcam for $555 million. Google also announced it partnered with Mercedes-Benz, Whirlpool and light bulb maker LIFX to integrate their products with Google’s Nest.
Meanwhile, Apple announced a smart home framework called HomeKit, which can be used for controlling connected devices inside of a user’s home. Apple’s connected car infotainment system is called CarPlay.
IDC expects the installed base of the Internet of Things will be approximately 212 billion “things” globally by 2020. This is expected to include 30.1 billion installed “connected (autonomous) things” in 2020.
