In in the present day’s world, steady connectivity appears like an on a regular basis given. However delivering it’s removed from easy. Uninterrupted constant community protection has traditionally been, and nonetheless is, arduous to realize. Mobile and wi-fi networks include explicit limitations, providing fragmented connectivity and use throughout gadgets. Energy effectivity makes this problem much more tough as gadgets require a constantly lively connection.

“Uninterrupted constant community protection has traditionally been, and nonetheless is, arduous to realize.”

To resolve this problem of world connectivity, we got down to take a look at LTE CAT-1 as a brand new resolution. Our purpose was to check steady robust connectivity even within the remotest of areas the place the expertise infrastructure considerably lags behind the developed world and connectivity is low. The query we requested ourselves was, may we bridge this huge hole and supply dependable web entry even within the areas with the weakest connectivity infrastructure?

The Check

We live-tested a number of monitoring gadgets throughout Europe and Africa. An airplane carried a number of SODAQ-manufactured gadgets with the NINA/LENA collection of U-blox, powered by Monogoto connectivity. Every monitoring machine confirmed the route traveled and reported from every touchdown location. The journey lined 10 international locations, starting in Europe, following the Nile River by way of Egypt and Sudan, and persevering with in direction of the east African coastal area of Tanzania earlier than heading additional south to Mozambique, Malawi, Zimbabwe, Botswana, and eventually South Africa.

On the Cell World Congress 2018, it was highlighted that LTE-M and NB-IoT, each low-power wide-area community radio communication applied sciences for linked gadgets, couldn’t resolve the connectivity problem in international locations with restricted IoT capabilities. It will take years to deploy these applied sciences because of the resource-intensive work required for roaming contracts with a number of suppliers. This will likely contribute to the rationale why chip and module distributors have famous that gross sales of LPWAN modules didn’t meet authentic estimations.


LTE CAT-1 is a ubiquitous expertise utilized by smartphones everywhere in the world and we believed it may supply low-cost and low-power world connectivity. CAT-1 expertise has been in improvement for years and its potential to revolutionize world connectivity has been lengthy anticipated. Units with LTE (Lengthy-Time period Evolution) expertise are able to reaching larger knowledge switch speeds in comparison with older generations like 2G or 3G.

As a result of it’s appropriate with older community applied sciences equivalent to 2G and 3G, even international locations with outdated infrastructure can leverage their current 2G and 3G networks. Plus, the give attention to wider protection permits community suppliers to increase their providers to distant or rural areas that will not have had entry to mobile connectivity earlier than.

International Connectivity Is Attainable

We realized that true world connectivity could possibly be achieved. Our key takeaway is that CAT-1 is effectively positioned to supply steady world protection even within the remotest of areas – it has the good thing about being extremely environment friendly, and needing low energy utilization, with out the draw back of CAT-M or NB-IoT protection limitations.
