As per the research by Telegeography, a total of 114 5G commercial networks out of which 30 networks in Q2, 2020 have been made live around the worldwide and is anticipated to increase by 2-fold i.e. 2014 by the end of 2020. The demand for data has scaled up and so is the urgency for deployment of 5G networks.
Though 5G has a lot of advantages than its previous versions, the process of 5G deployment is not so simple and easy task. Operators face critical challenges in 5G deployment. Mobile network operators (MNOs) deal with various issues that prevail with the 5G implementation as mentioned below.
5G networks operate on higher frequencies nearly up to what is computer engineering and these bands have increased capacity capable of delivering ultra-fast speeds 20 times more than LTE networks theoretical speed. However, availability and cost of spectrum band is still an issue for the operators. They need to bid for these higher spectrum bands as they continue to build and deploy 5G wireless networks.
The initial phase of 5G deployments are based on non-standalone 5G which uses LTE core and LTE access is the anchor for New Radio (NR). Control and excess user traffic above LTE traffic are administered by LTE eNB and 5G gNB. Configuration of hybrid LTE-NR using the macro LTE layer is beneficial for the deployment of 5G in mmW spectrum and increases its mobility in between the hotspots. This mobility gained from mmW works well at low speeds. Nevertheless, these benefits are evolved from the performance of the dual connectivity (EN-DC) and is very challenging to perform 5G network testing due to its complex nature. It requires synchronisation between gNB and eNB for data transfer and signalling to the NR.
