We live in a time of change. Rare is the day when we don't hear terms like 5G, IoT, communications networks or digital dividend. From Atelei, we want to shed some light on a sea of acronyms and communications concepts.
Today's networks could be classified as follows: las who enter the world of the Internet of Things (IoT) and those who do not. This way you could separate between 2G / 3G / 4G and 5G / NB-IoT / LTE-M.
Today, there is a growing demand for communication frequencies for the consolidation of new wireless services as evidenced, among others, by mobile communication systems, digital terrestrial television broadcasting networks or various broadband wireless access systems. In addition to this growing demand for frequencies not all of them have the same characteristics, which results in different coverage capabilities or different noise and interference properties. Also the different types of packages (voice, audio, data, video) require specific frequency bands.
All these characteristics mean that until now certain frequencies have been considered particularly suitable for providing specific services, including sometimes inevitable conflicts between different services competing for the same band.
As a result of the 5G auction, the bands and frequencies occupied by some DTT channels, in particular the channels that used the highest part, have had to be moved to the lower part of their assignment spectrum in order to free up the spectrum they occupied in the 694-790 MHz band that some 5G bands will use from this year.
2G and 3G networks will be phased out in favour of 5G deployment (although 2G and 3G networks remain essential for IoT and M2M devices due to their lower cost and lower cost per megabyte compared to 4G modules and reliable global coverage). In this sense, and as an example, Vodafone has already announced the shutdown of 3G throughout Europe between 2020 and 2021, while Deutsche Telekom has plans to shut down in 2020. However, none of them, not even Telefonica, have made public the plans for the switch-off of 2G.
The 5G network will bring a series of improvements, among which are major battery life of devices that use it, coverage extension and support for one million devices per square kilometer.
Currently there are 94 commercial launches of IoT mobile networks in 50 marketsThe number of mobile operators is growing month by month, thanks to the support of 98 operators, 2,100 developers and 1,300 companies that promote the Mobile IoT initiative of the GSMA operators' association. More than a hundred modules are commercially available that work with the NB-IoT and LTE-M standards supported by the Mobile IoT initiative and 47 IoT laboratories are operating in 21 countries. Many governments are looking to the NB-IoT network to carry out digital transformation of their countries and thereby improve communications and ensure more efficient installations.
At Atelei, we have been preparing for some time for the change that will come in the next few years with the deployment of these new communications frequencies. We have "under our belt" the latest generation devices that already make reliable use of the recently deployed NB-IoT bands and we are already working with the 5G standard.
