WHAT IS 5G ?WHAT IS 5G ? Although 5G is not expected to reach the British market until 2020, several companies have already started investing to prepare ahead for the new wireless mobile standard, and trial 5G networks are already being set up in other corners of the world. 5G stands for the fifth generation of the next wireless mobile standard. According to the Next Generation Mobile Network's 5G white paper, 5G connections must be based on 'user experience, system performance, enhanced services, business models and management & operations'. The 5G New Radio (NR) specification was released by standards body 3GPP in late 2017 - and chips are already being built '5G- ready'. And according to the Groupe Speciale Mobile Association (GSMA) to qualify for a 5G a connection should meet most of these eight criteria:
ADVANTAGES OF 5GADVANTAGES OF 5G Like all the previous generations, 5G will be significantly faster than its predecessor 4G. This should allow for higher productivity across all capable devices with a theoretical download speed of 10,000 Mbps.
ADVANTAGES OF 5GADVANTAGES OF 5G Current 4G mobile standards have the potential to provide 100s of Mbps. 5G offers to take that into multi-gigabits per second, giving rise to the ‘Gigabit Smartphone’ and hopefully a slew of innovative services and applications that truly need the type of connectivity that only 5G can offer," says Paul Gainham, senior director, SP Marketing EMEA at Juniper Networks. Plus, with greater bandwidth comes faster download speeds and the ability to run more complex mobile internet apps.
DISADVANTAGES OF 5GDISADVANTAGES OF 5G However, 5G will cost more to implement and while the newest mobile phones will probably have it integrated, other handsets could be deemed out of date. A reliable, wireless internet connection can depend on the number of devices connected to one channel. With the addition of 5G to the wireless spectrum, this could put us at risk of overcrowding the frequency range. The problems with 4G and even 3G aren't exactly filling us with the hope of an immediate super fast connection. For a long time (and still even now) certain handsets and areas of the UK don't support or can access 4G connections, so the rollout for 5G is likely to be very patchy.
THE FUTURE OF 5GTHE FUTURE OF 5G As 5G is still in development, it is not yet open for use by anyone. However, lots of companies have started creating 5G products and field testing them. Notable advancements in 5G technologies have come from Nokia, Qualcomm, Samsung, Ericsson and BT, with growing numbers of companies forming 5G partnerships and pledging money to continue to research into 5G and its application. Qualcomm and Samsung have focused their 5G efforts on hardware, with Qualcomm creating a 5G modem and Samsung producing a 5G enabled home router. Both Nokia and Ericcson have created 5G platforms aimed at mobile carriers rather than consumers. Ericsson created the first 5G platform earlier this year that claims to provide the first 5G radio system. Ericsson began 5G testing in 2015.
WHO INVESTING IN 5G?WHO INVESTING IN 5G? Both Nokia and Ericcson have created 5G platforms aimed at mobile carriers rather than consumers. Ericsson created the first 5G platform earlier last year that claims to provide the first 5G radio system, although it started 5G testing in 2015. In early 2017, Nokia launched "5G First", a platform aiming to provide end-to-end 5G support for mobile carriers. Looking closer to home, the City of London turned on its district-wide public Wi-Fi network in October 2017, consisting of 400 small cell transmitters. The City plans to run 5G trials on it. Chancellor Philip Hammond revealed in the Budget 2017 that the government will pledge £16 million to create a 5G hub. However, given the rollout of 4G, it's unknown what rate 5G will advance at.

The hub was granted £38 million to make compound semiconductors which underpin this technology. Ericsson also partnered with BT, Verizon and Kings College London to build the world’s first 5G drone trial in February 2018. This was launched from the US by Verizon and tested in London using a 5G network slice in BT’s network. A number of network providers have also begun investing in their expected 5G rollout, with EE claiming to begin roll in 2019 and Vodafone to offer full 5G services from early 2020. Vodafone completed its first 5G test with a 3.4GHz spectrum in April 2018.
WHAT IS 5G, AND WHAT IS THE DIFFERENCE BETWEEN 4G / LTE AND 5G ?What is 5G, and what is the difference between 4G / LTE and 5G? The next (5th) generation wireless network will address the evolution beyond mobile internet to massive IoT (Internet of Things) for the horizon 2019/2020. The main evolution compared with today’s 4G and 4.5G (LTE advanced) is that beyond data speed improvements, new IoT and critical communication use cases will require new types of improved performance. For example “low latency” is what provides real-time interactivity for services using the cloud: this is key to the success of self-driving cars for example. Also, low power consumption is what will allow connected objects to operate for months or years without the need for human assistance. Unlike current IoT services that make performance trade-offs to get the best from current wireless technologies (3G, 4G, WiFi, Bluetooth, Zigbee, etc…), 5G networks will be designed to bring the level of performance needed for massive IoT. It will enable a perceived fully ubiquitous connected world.
HOW 5G WORKS ?HOW 5G WORKS? Wireless networks are composed of cell sites divided into sectors that send data through radio waves. Fourth-generation (4G) Long-Term Evolution (LTE) wireless technology provides the foundation for 5G. Unlike 4G, which requires large, high-power cell towers to radiate signals over longer distances, 5G wireless signals will be transmitted via large numbers of small cell stations located in places like light poles or building roofs. The use of multiple small cells is necessary because the millimeter wave spectrum -- the band of spectrum between 30 GHz and 300 GHz that 5G relies on to generate high speeds -- can only travel over short distances and is subject to interference from weather and physical obstacles, like buildings. Previous generations of wireless technology have used lower-frequency bands of spectrum. To offset millimeter wave challenges relating to distance and interference, the wireless industry is also considering the use of lower-frequency spectrum for 5G networks so network operators could use spectrum they already own to build out their new networks. Lower-frequency spectrum reaches greater distances but has lower speed and capacity than millimeter wave, however.
WHAT IS THE STATUS OF 5G DEPLOYMENT ?WHAT IS THE STATUS OF 5G DEPLOYMENT? Wireless network operators in four countries the United States, Japan, South Korea and China are largely driving the first 5G buildouts. Network operators are expected to spend billions of dollars on 5G capital expenses through 2030, according to Technology Business Research Inc., although it is not clear how 5G services will generate a return on that investment. Evolving use cases and business models that take advantage of 5G's benefits could address operators' revenue concerns.
WHAT IS THE STATUS OF 5G DEPLOYMENT ?WHAT IS THE STATUS OF 5G DEPLOYMENT? Simultaneously, standards bodies are working on universal 5G equipment standards. The 3rd Generation Partnership Project (3GPP) approved 5G New Radio (NR) standards in December 2017 and is expected to complete the 5G mobile core standard required for 5G cellular services in late 2018. The 5G radio system isn't compatible with 4G radios, but network operators that have purchased wireless radios recently may be able to upgrade to the new 5G system via software rather than buying new equipment. With 5G wireless equipment standards almost complete and the first 5G-compliant smartphones and associated wireless devices commercially available in 2019, 5G use cases will begin to emerge between 2020 and 2025, according to Technology Business Research projections. By 2030, 5G services will become mainstream and are expected to range from the delivery of virtual reality (VR) content to autonomous vehicle navigation enabled by real-time communications (RTC) capabilities.
