In this episode, Allot's Product Marketing Director, Michael Schachter, discusses QoE with Moti Goldshtein - Allot's AVP of Smart Products.

We all are familiar with the ever-growing traffic demand from the ever-growing variety of applications and web services, and we all are also end-users who appreciate high QoE - but this is a significant challenge for CSPs.

5G is happening, bringing new and exciting use cases like gigabit speeds to the UE, low latency, slicing, etc. However, 5G is being deployed gradually, alongside existing 4G deployments, in a variety of deployment strategies in the market, from "native" 5G SA deployments, 5G SA in parallel to existing 4G network, "dual mode" cores, 5G NSA, etc. Hence, we expect 4G to remain deployed for several years ahead, so we'll \ see "congestion hot spots" where 5G is not an option due to a lack of spectrum resources or due to coverage (indoor) and technical issues like DSS (dynamic Spectrum sharing).

Other delays could depend on commercial issues like the significant CAPEX/OPEX investment needed for nationwide 5G coverage, which spreads over a long period.

By using core-based SW solutions like those offered by Allot, the MNOs can add "virtual capacity" to their LTE cells and prolong their life expectancy with minimal to no impact on QoE hence freeing up CAPEX/OPEX to enable the MNO to focus their resources in 5G deployment, customer care, and added value services to their end-user.
