The speed of individual LTE networks depends mainly on how many frequency bands each operator has. However, there is also a very effective way to speed up current 4G networks without having to buy a licence for new frequencies. Nokia, Qualcomm and one of the American operators have just shown that LAA technology, referred to here, allows you to download data with 1.45 Gbps speed.

Mobile network operators are constantly looking for new solutions that increase the efficiency of using their frequencies. The current situation prevents them from buying new channels, which would speed up the existing LTE networks. That is why telecommunications company engineers came up with the idea of ​​unlicensed band management for the 4G network. The 5 GHz band used by Wi-Fi networks will be at first glance. For this purpose, LAA (Licensed Assisted Access) technology has been developed, which allows aggregation of licensed LTE bands with unlicensed 5 GHz band. Such solutions have been discussed for a long time. Everyone is wondering how it will work in practice.

Nokia, Qualcomm and Verizon showed that LAA is a chance for ultra-fast LTE

The tests of this technology have been carried out in one of the American cities. Nokia has provided a base station that uses LAA technology. Qualcomm has prepared a smartphone (and more specifically a test mobile device) equipped with the Snapdragon X24 modem. However, the American operator Verizon has made its network available. It is worth mentioning here that the tests were carried out in the so-called the field with the use used by the operator’s customers. The maximum download speed was 1.45 Gbps. This is a very good result.

LTE LAA

The operator connected new LAA modules to the base station, which previously served only 2 licensed LTE bands. During the test, up to 6 carriers were aggregated, with 2 of them coming from previously used bands, and the remaining 4 working in the unlicensed 5 GHz band. Satisfactory test results show that this type of solution can work despite nearby Wi-Fi networks. Access pointy is the biggest “enemy” of LAA, because their work reduces the efficiency of the new solution. LAA base stations are designed in such a way that they do not interfere with Wi-Fi networks using the same frequencies.
