Whereas most carriers use low-band spectrum or LTE, which offers great coverage area and penetration, it is getting very crowded, and peak data speeds only top out at around 100Mbps.
5G, on the other hand, offers 3 different Spectrum bands, which are:
- Low-band spectrum or LTE.
- Mid-band spectrum. This gives faster coverage and better latency than low-band but isn’t as good at penetrating buildings. Mid-band spectrum will offer peak speeds up to 1Gbps.
- High-band spectrum / mmWave . This spectrum can offer peak speeds up to 10 Gbps and has very low latency, although it has a low coverage area and building penetration is poor.
- In the UK, it is likely that there will be 2 different, location-based frequencies. Sub-6GHz (gigahertz) is likely to be the first offered to users, and the (expensive) high-band spectrum / mmWave for use in densely populated areas. This could mean limitations on where an owner can use their 5G phone (when they eventually get one).
What Can We Expect From 5G?
More frequencies, faster speeds and less latency should mean big improvements in broadband (particularly commercial) and an end to slowdowns during busy times of day that have been experienced due to the overcrowding of the current limited LTE.
Also, the frequency spectrum needed for 5G is finite, and even with additional spectrum that has been auctioned to the UK’s mobile networks, more will be needed. This may mean some crowded traffic in the first wave, with things not improving until more auctions have taken place.
It is also likely that other technologies will need to be developed and trialled in order to help 5G live up to its promise. Lessons learned about 5G in other countries (e.g. China) will take time to be noted and incorporated in the UK network to help it deliver maximum benefits.
Real-Life Business / Life Applications
Anticipated ways that 5G could improve things in our lives and for businesses include:
- Improvements to health care. Communications and sensor networks in health care are likely to be improved, therefore, benefiting patients, doctors and other staff.
- Improvements in the IoT as devices require fewer resources, and huge numbers of devices can connect to a single base station, making them much more efficient. IoT improvements could help with all kinds of services e.g. public services such as smart bins and smart lighting, remote healthcare services, and CCTV / surveillance services.
- A boost to virtual and augmented reality.
- Benefits for the growing autonomous vehicle market as 5G provides the constant, guaranteed connection that they need.
- Advantages for companies operating delivery drone/robot services e.g. Amazon may also get a boost from reliable and powerful 5G connections.
- The low latency of 5G offering allowing more remote device control e.g. reducing risk in hazardous environments and allowing technicians with specialized skills to control machinery from anywhere in the world.
What About 5G Phones?
For phone manufacturers, manufacturing 5G phones will be a slightly different and more complex proposition. For example:
- 5G phones are more complex e.g. they need a more complex antenna. These mean extra production costs which are likely to be passed on (with first-wave prices) to customers. It is thought that 5G compatible phones will be priced between £450-£540, with higher prices for leading brand models e.g. Samsung, Apple and Huawei.
- Miniaturisation of a more complex 5G phone presents challenges. The first generation of 5G phones may, therefore, be a little larger than a normal smart-phone.
- Launching new handsets before the new network has been rolled out could simply annoy buyers and damage brand reputation, and many customers may simply delay buying a 5G anyway until they are confident that 5G is performing well and will offer them all the benefits.
- The first 5G smart-phones will need two modems, one standalone 5G modem, and one that still works on 4G and older networks (for when 4G isn’t available).
5G has taken nearly10 years to develop and although some companies may already be rolling out fixed 5G to some cities in the developed world, mobile 5G won’t start making appearances in cities around the world until later in 2019.
What Does This Mean For Your Business?
The same increased speed and lower latency of 5G that allows downloading films and games in seconds and watching them without any buffering, is also likely to provide many new and innovative opportunities, and could help provide a boost to new industries
Many different types of businesses could benefit from improved connectivity with remote workers or with salespeople in remote areas.
Also, the news from an O2 forecast is that 5G could deliver time savings that could bring £6 billion a year in productivity savings in the UK, and that 5G-enabled tools and smart items could save UK householders £450 a year in food, council and fuel bills.
We will, however, have to wait for 5G networks and services to be operating and offering all the predicted benefits, and as well as being somewhat expensive, purchasing a 5G phone may be something that many people will hold-off doing until they’re confident they’ll get the promised value from it.
