Bluetooth and market trends in mesh networking
Bluetooth and market trends in mesh networking

“Bluetooth Mesh is big,” says Lee Ratliff, Principal Analyst for Connectivity and IoT at IHS (www.ihs.com). “Mesh is important because it addresses some of the weaknesses of Bluetooth. You can [theoretically] extend the range by a km or more just by hopping from node to node. Obviously that goes a long way towards correcting what has always been a weakness of Bluetooth, which is range.”

Single-core, low-footprint NB-IoT design challenges
Single-core, low-footprint NB-IoT design challenges

Following a big industry debate about the impact of the Internet of Things on existing networks and LTE compatibility, a narrowband IoT (NB-IoT) standard (or Cat-NB or Cat-M2) was published in June 2016. The new standard allows for more than 200,000 devices in a cell, and coverage has been improved by 20 dB compared to general packet radio service (GPRS) reference, allowing low-power battery-operated devices to be reached, for instance, in a remote basement or behind walls.

The effectiveness of OTA has been proven in applications like mobile phones that receive new features and fix bugs through periodic upgrades and the relatively new OTA firmware upgrade feature with Bluetooth Low Energy (BLE) has brought this same ability to the Internet of Things.

From competition to coopetition – Standards groups work toward unifying IoT with dotdot

In essence, the dotdot language can be seen as an extension of the ZigBee Cluster Library (ZCL) specification used to issue commands across ZigBee 3.0’s interoperable application layer. In addition to the application layer remaining slim, however, dotdot has also been made compatible with other networks to allow for communication across disparate transports.

Executive Outlook

A look at NB-IoT and LP-WAN from the top

The low-power, wide-area networking (LP-WAN) market is beginning to take form, with technologies such as LoRa, Sigfox, and LTE Cat-NB1 (formerly NarrowBand-IoT (NB-IoT)) looking to fill the void left by sunsetting 2G networks that connected a variety of Industrial Internet of Things devices. While this sector promises to be a significant contributor to the number of overall IoT connections in coming years thanks to the comparatively low cost of the enabling network technologies, exactly which of these will emerge as viable large-scale solutions remains to be seen.

Leveraging the range of Sub-1 GHz technology to connect ultra-low power sensors to the cloud

There are so many wireless technologies one could use to connect sensor networks to the cloud. It becomes much more difficult to connect these networks to the cloud when you need longer range than just a few tens of meters or in the use case where networks contain hundreds of sensors.
