Press release: Nokia announces that it can upgrade 5 million 4G transmitters to 5G with a software update, Mobile operators could thus save several billions of dollars.
Nokia launched software that enables mobile operators to migrate 4G transmitters manufactured by the OEM to 5G. The Finnish telecommunications equipment manufacturer ensures that this technology does not require any site visits or equipment replacement. The Finnish telecom equipment manufacturer says it hopes the software will help it in its battle against Huawei and Ericsson for the next wave of 5G orders.
Nokia estimates that this solution will potentially save the telecom industry tens of billions of dollars in engineering and site overhaul costs as communication service providers are able to upgrade their 5G/NR networks to FDD using software," Nokia said in a release.
"The ability to upgrade 4G/LTE transmitters via a software upgrade will greatly facilitate the deployment of 5G/NR, avoiding costly and disruptive site visits. Nokia has a large base of 359 4G/LTE customers most of which are upgradeable. This will provide operators with a new and easier way to establish 5G/NR coverage in lower bands through spectrum redesign.
"Nokia also has a Dynamic Spectrum Sharing System (DSS) already in place in live networks covering 2G/GSM-3G/WCDMA-4G/LTE and has recently introduced DSS for 4G/LTE-5G/NR. This capability complements a DSS solution, covering all access technologies and making the 5G/NR radio frequency realignment a simple and efficient process. In a typical case, DSS will be introduced on one or a few 4G/LTE bands which will then be combined with carrier aggregation between other bands operating only in 4G/LTE or 5G/NR," says Nokia.
At present, approximately one million transmitters can benefit from this software upgrade. But Nokia promises that the number of eligible antennas will be 3.1 million by the end of the year and more than 5 million by 2021.
In addition, questions remain as to the ability of the transmitters to use the high frequencies provided by the 5G standard, as there are no hardware changes. Although this is a cost-effective solution, whether these installations can match the performance of basic 5G antennas remains to be determined.
