Land Observations Networks Modems and Sims - Re-tender

Description

We operate a network of around 300 automatic weather stations (AWS), mostly in the UK, but also a small number overseas. The weather observation data collected at these sites is collated on a logger at site and then communicated every minute to our central cloud based system in real time. Some sites have mains power, some operate on a 50W solar panel. The majority of sites have 4G connectivity, but there are a subset that only have 2G connectivity at present. We are looking for a supplier to provide a communications solution to allow for the real time transfer of our land surface observation data to our central cloud based collection system every minute in real time.
