Thingstream, based in Bournemouth UK, claims to be able to provide IoT connectivity in 190 countries using the MQTT protocol over the networks of 600 mobile network operator partners.
The company says it has been operating in relative stealth mode to date but has had an impressive first half of the year, with a number of new customers now integrating its IoT technology and it is scaling up of operations across the globe.
Thingstream “leverages the low power messaging capability already built into existing global GSM networks utilising MQTT-SN via USSD, making it secure (no IP address) and providing predictable low costs.”
USSD (Unstructured Supplementary Service Data) is a real-time messaging protocol for GSM cellular networks. Messages can up to 182 alphanumeric characters long and two-way exchange of data is possible.
