Altair shows first NB-IoT at 450MHz using connected tractors

By Nick Flaherty www.flaherty.co.uk

Altair Semiconductor has shown the first implementation of LTE CAT-M/NB-IoT running at 450MHz, giving lower power and longer range.
The ALT1250 chipset is powering the Asiatelco LM66 IoT module, which provides LTE connectivity for a range of connected devices, and has been developed to provide agricultural solutions for large-scale farming in Brazil.

Operating on the 450 MHz LTE spectrum and using Ericsson's LTE eNBs, Altair's cellular IoT chipset enables agricultural companies using smart sensors and connected tractors applications to optimize farming practices. The solution uses location tracking, driver behaviour monitoring, and fuel consumption optimization.
“Altair is looking to revolutionize cellular IoT connectivity across Brazil. The solution was field tested and demonstrated the potential of 450 MHz’s frequency reach in agriculture use cases. It will certainly enable an exciting range of transformative applications in rural areas”, said Paulo Bernardocki, Head of Solutions Radio, Ericsson LATAM South.

Altair's highly integrated dual-mode cellular IoT chipset, ALT1250, is the only available CAT-M and NB-IoT solution trialed to run on 450 MHz. The chipset supports Global LTE bands within a single hardware design and supports both satellite and cellular positioning tracking. The Altair-powered LM66 modules are capable of connecting and delivering data over the LTE450 network as well.

"There's a global trend resulting in a significant amount of 450 MHz spectrum being re-allocated for new use cases on LTE450 networks, as legacy 2G and 3G networks are being retired," said Igor Tovberg, Altair's Director of Product Marketing. "450 MHz is ideal for agricultural IoT applications, providing superior network coverage essential for the wide and often remote farming locations that exist in Brazil."

Altair is part of the Sony Group following its acquisition in early 2016.
