At the first stage, eMBB is first priority. mMTC will use NB-IoT. uRLLC will depends on standard and market demand.5G will work on 3.5GHz and MMW band.
4G and 5G network will co-exist for a long time

Application Awareness Interworking between LTE and NR
3GPP TSG SA WG2 Work Item
The objective is to study the mechanisms to address use cases dealing with policy driven selection of E-UTRA or NR by the core network » Scenario 1: The E-UTRA access node and NG-RAN access node are
connected to EPC and 5GC respectively.
» Scenario 2: The E-UTRA access node and NR access node are connected to 5GC in a dual connectivity mode.
NG-RAN remains making any final decisions regarding handover/redirection/switching as RAN has the responsibility into radio and load conditions which govern the success of such a decision.

- Strong decrease in LTE-A network launches in 2017: 212 networks at end March 2018- But strong rise in LTE-A Pro launches: LTE Rel.13, with 3 to 5 CA (Carrier aggregation) to
boost peak DL speeds up to 450 Mbps, support for LTE-U and LTE-AA- And growing global trials/deployments for Gigabit LTE: 4x4 MIMO, multi channel CA
and 256 QAM, using also LTE-U or LTE-AA 41

Overall Architecture
5G system aims at providing a flexible network architecture, enabling new business cases and models supporting vertical industries. Network slicing emerges as a promising future-proof framework and needs to be designed from an end-to-end perspective. Furthermore, security architecture shall be natively integrated into the overall architecture. The support of verticals is enabled also by a flexible function deployment and relocation based on the requirements in terms of capacity, latency and reliability.

Europe: actively preparing 5G & fully monetizing 4G…
• Operators have begun lab tests and multiplied partnerships with vendors to assessbusiness cases
- Nordic & Baltic Regions: 5G development plan for earlier launches (2018-2019)- TIM is testing various use cases with Fastweb and Huawei in Bari and Matera- Orange 5G launches in 2020-2021; trials with Ericsson & Nokia, and agreement
with Peugeot to develop the 5G connected car.- Telefonica strongly committed to 5G, but wants « to adapt the network to the
customer and not the other way around »…• Verticals:
- Smart cities drive interest: 15+ « 5G trials cities »- strong interest for connected car, low-latency for factory automation, healthcare- Euro2020: clear target for 5G, as a popular event, displayed on 13 different cities- role of SMEs, contributing to research & standardization, supported by EU Research programmes
