Mobintec Ltd is an independent telecommunications consulting firm founded in 2002 in the UK. The document discusses Mobintec's Managing Director Dr. Shahram G Niri's presentation on 5G at the 5G World Summit in 2017. The presentation addresses lessons learned from previous network transitions and outlines challenges for the transition to 5G, including spectrum availability and harmonization, unclear business cases for early 5G deployment, and the need for cooperation across industries. It argues that 5G will require rethinking business models, policies, regulations and a shift toward more open, virtualized, and shared network architectures and spectrum ownership models.

Delivered by NR using better Waveforms, larger MIMO, operation in
mm waves, some other clever algorithms
Low latency: limited to small number of services with yet no clear
business models nor a clear regulations ….
Data Rate: 4G does not really come short on the speed
Current speeds are more than enough for MBB & MTC
Capacity: likely bottleneck for 3G and 4G BUT could be dealt by
densification (small Cells)
Coverage: Missed out target?
Ultimately the barrier to ubiquitous coverage is not technology but the cost
5G is not and can not be the means of providing ubiquitous MBB to whole populations

5G Services & Technology Playfield
The performance requirements and targets vary
Spectrum availability & more importantly
global harmonisation, still a major challenge in our
industry
The ARPU for MBB, not likely to increase but the
cost elements on the rise
The overall cost of delivery ultimately dictates
take-up of new technologies
Best utilisation of the assets (spectrum): indicate
certain spectrum deployment
Today, it is not clear what flavour of 5G will be
launched first
Challenges of bring none-traditional services providers into the game & readiness of
the traditional Telco providers to enter into new vertical segment:
Real 5G specific services may be some years down the line!

5G & Spectrum Scenarios
1GHz 3GHz 30GHz 60GHzFrequency Band
Most efficient utilisation (Best use of low, Mid and High Frequency)
Availability of enough bandwidths, Ideally 100+ MHz channel bandwidth
Realistic and pragmatic performance targets
Best use of the technology
Combination of licensed and unlicensed & shared and dedicated spectrum allocation
Timely refraining of spectrum particularly in sub 1G
Revisiting the exclusivity (LTE-U, LTE-LAA, …)
Gradually shifting away from Operator-owned spectrum
Harmonisation is a key to success
Spectrum remains to be a major challenge for 5G and for the wireless industry

SDN & NFV:
Moving away from a HW dominates and dedicated HW
base telecom solutions to solutions delivered through SW

multiple virtualised NW functions
Moving towards the world of servers and routers and
getting closer to IT operations models
Moving away from vendor lock-in and vendor specific
solutions to more homogenised NW
Challenges
Lack or slow interest from most network vendors (more
open standards and interoperability)
Loss of revenue (tougher competition, differentiation
will be limited to SW solutions
Changes in operation models (efforts and cost of
integration in HW may shift to integration in SW)
5G may not really meet its economic targets without
SDN & NFV
Significant cost benefits enabled by lower unit cost, lower operation cost,
more scalability, faster deployment, longer solution life cycle, …

Concluding Remarks
The experience of 4G to 5G, different from that of 3G to 4G
 Still a lot of life in 4G & 4G+
 Capacity the major shortcoming of 4G to be overcome by densification
 Small cell a key part of 5G but the 4G small cell may will be the 1st stop
 Lack of clear business case for early 5G deployment (Cost and RoI)
 Rush to 5G a threat for both vendors & operators
 Gov. Bodies and Policy maker: Spectrum remains a challenge for the wireless industry
(ownership, allocation, harmonisation)
 Service Providers: Revisiting the willingness to greater degrees of sharing
 Vendors: Openness to open Interfaces and true multivendor solutions
 Eco-system: Disruptive in business, Meaningful and win-win partnership between
traditional Telco & new industries - Success depends on rethinking business models,
partnerships, policies and regulation
The fast and the furious: for the cars and Hollywood NOT 5G!
