Proving the Business Case for the Internet of Things

HMS connects remote assets through NB-IoT and Cat-M1

Swedish communications firm HMS Networks has announced the Anybus Wireless Bolt IoT, which enables cellular-based internet connectivity for assets in the field using the LTE-based NB-IoT and Cat-M1 networks.
 
Companies are looking to connect remotely located assets for remote monitoring and control over the internet. However, many times there is no local infrastructure available to connect such assets to the internet in a traditional way.
 
The Anybus Wireless Bolt IoT targets this by providing cellular-based internet connectivity over NB-IoT and Cat-M1 for remote assets that are otherwise hard to reach and connect.
 
Wireless Bolt IoT includes all elements needed to get stationary or mobile assets online over a cellular connection. Packaged in the Bolt format for on-asset M50 hole mounting, it has an IP66 or IP67 housing with UL Nema 4X certificate for outdoor mounting, an integrated cellular antenna with a modem, a microcontroller and firewall. 
 
A built-in Ethernet port is used to connect to a corresponding Ethernet port on the asset. The configuration is done via a built-in web server or by sending Rest commands via the Ethernet port. After this, it will transfer data transparently from the asset to the cellular internet connection using TCP and UDP based protocols.
 
Power over Ethernet (PoE) is supported, but power can also be supplied via separate terminals. 
 
On the cellular link, it communicates using NB-IoT and Cat-M1 with 2G (GPRS and Edge) fallback, which enables deployment almost anywhere in the world.
 
These LTE standards are so-called LP-Wan technologies (low power wide area network) suitable for IoT use cases that typically require low power consumption, low bandwidth (25 to 300kbit/s), good geographical coverage and a low connectivity cost per asset.
 
An onboard SIM-card slot enables connection to any operator network worldwide. Private enterprise networking of assets is also supported using cellular private APN networks.
 
Wireless Bolt IoT is suitable for battery-driven assets not connected to the electric grid, such as electronic road signs, traffic metering stations and water level measuring stations. Its low-power mode enters a low-power state when data are not being transferred, which means the size of the battery or power supply can be kept small.
 
HMS develops and manufactures products under the Anybus, Ixxat and Ewon brands. Communications for building automation are offered through its Intesis subsidiary. Development and manufacturing take place at the headquarters in Halmstad, Sweden, and in Ravensburg, Nivelles, Igualada and Wetzlar. Local sales and support are handled by branch offices in Germany, USA, Japan, China, Singapore, Italy, France, Switzerland, Spain, India, UK, Sweden, Finland, South Korea and UAE, as well as through a worldwide network of distributors and partners.
 
HMS employs more than 600 people and reported sales of SEK1366m in 2018.
