"We all use 4G now and are getting a liking to how voice and data services should be delivered. With 5G we can expect faster resolutions, better time responses and video real time accuracy" explained Phil Sheppard, Director and Principal Consultant at Clear Technology Consulting Limited at the 'Mobile Prestige Lecture: 5G Opportunities' lecture organised by the IET Berkshire Local Network and hosted by Abhaya Sumanasena.
 
Phil walked the delegates through what we can expect with 5G deployment speeds, and why the 20Gbps peak speed is still yet to come - in the meantime the initial deployment efficiencies will still be a massive change on how we consume voice and data in our homes and businesses.

Global 5G economy is expected to reach $2.2 Trillion and is expected to have a high impact on Agriculture, Manufacture & Utilities, Financial and Professional Services - including the many more new industries that are not yet established. By 2025, globally, 4G will have be reduced down to 60% usage, and realistically the trend towards 5G will have moved to a 20 % uptake.

Currently, 5G is scoped for the 3.4 Ghz and 3.8 Ghz range and is on the opposite end of the spectrum to x-ray and gamma ray frequencies. It is expected to have normal rules of safety applied, just with more focus on power as the 5G range has heating implications. Simply, lower the frequency the better the coverage and higher the frequency the better the bandwidth and as 4G uses FDD , using TDD makes 5G more efficient - that's why we have the hype! It's just like 4G, but different and a lot better.

Antennae technology will also change and with 64T64R that uses beam forming, existing 4G radio sites (those masts on the roof tops),  can have 'massive mimo' units added, or even radio units can be added within existing 4G radio sites for the transition - but it takes time and is costly. The attributes of 5G are mainly capacity, speed, latency, architecture and ability to have larger quantity of user nodes. Though, currently, in reality, 4G gives you 40 ms latency , and 5G currently gives 10 ms latency - expected to get to 2 ms latency, once we move to pure 5G 'standalone infrastructures'.

'Network Slicing' is set to play a big part in the 5G ecosystem - slicing will let you enhance geo-location services with dedicated real-time speeds, with better performance and capability per region or area. This will help in hospitals, utilities, emergency response and other critical infrastructures to be far more progressive - gaming too will have real time 6-10 ms latencies - so that virtual gym session will happen in the park soon!!

The ability to have your own 5G networks is also a reality, however you need to know how to use it, no point developing a solution that does not understand the trade-off between capacity and coverage. Current genuine use cases are for manufacturing plants which will do away with costly cabling so you can save millions and provide a better granular service within the factory like real time customised build processes that have real time engineering interaction.

During QnA, I asked if we are likely to see any dedicated 5G Cyber Security standards to be developed, and fortunately 5G will have better considerations for software and cloud native core systems inherently and these are expected to be refined further, such as granular mechanisms on how 'access-controls' are to be deployed, there are DDOS standards and many more attack surface cyber defence standards being developed that will complement the 5G spectrum. 5G will add more means and methods to have better security, but it will only be effective if done correctly.

A pragmatic webinar that explained the realities of 5G - yes it will be fast, just not straight away. 

The IET have many publications on 5G standards at the IET Digital Library found here.
