What is 5G?
let’s talk about 5g the latest and greatest mobile network that they say is going to transform our lives. it sounds promising 5g will let us download an HD movie in seconds. that’s just hilariously fast. doctors will be able to perform remote surgery with virtually; no lap time and it’ll make self-driving cars smarter and safer. but there are also suspicions that 5g will expose us to more security breaches privacy issues and even health problems. so what exactly is 5g and how much of the excitement or fear is just heightened. we all know 3G and 4G they’re the mobile networks we use today you see them at the top of your phone and they give us access to the Internet. but we’re now making way for the next generation. 5g is promoted as the best and fastest connection around and in some countries it’s already available. South Korea launched 5g networks last year. so did providers in China, the UK, the US, and Germany, new 5g phones are on the way to Samsung released the first one in 2019 bringing commercial 5g to life.
How 5G works?
before the rest so here is how it works 5g uses a wide range of radio frequencies starting from the lower end which we already use for television and Wi-Fi all the way up to what’s called millimeter waves which are extremely high frequency and used for things like radar guns and security screening at airports. this means that VG can carry huge amounts of data faster and that’s a big reason why we need it. our mobile networks are running out of capacity soon. they won’t be able to accommodate the growing number of devices were using and there’s money to be made. governments will earn revenue by granting 5g licenses. the other reason to move to 5g innovation we have more sensors in the world clocking data and transmitting them back and forth in a smart intelligent hybrid way. it is sort of like a Jetsons-like futuristic technology my ingredients and I get recipes he’s talking about what they call the Internet of Things and what it means is more and more of our devices like smart speakers or exercise equipment will remember and even anticipate our preferences and five genes will allow them to talk to each other at a record speed. it will be connecting many more devices to the Internet for the same probably amount of money and without interfering one to each other.
Challenges with 5G network.
the challenge with 5g is coverage shorter wavelengths carry more information but are more easily blocked by things like trees and walls. with 4G transmitters or base stations can be several kilometers apart but with 5g they need to be closer which means we need more of them one estimate suggests the US alone will have to install 1million new towers that’s why 5g is really more of a gradual rollout, not a launch because all of that back-end infrastructure will take years to build. what we’re going to see as a substantive replacement or upgrade of the course systems that telecommunications companies provide that’s going to be a really massive investment. the problem in some places is that big phone companies have only just finished building their 4G networks. they want to both enjoy the benefits from the week the profits of money they put into it. but also they recognize that well there’s this assertion that we’re in a 5g race. it’snot a short-term race it’s a very long-term marathon and the race is already getting crowded some of the big names in 5g are Ericsson from Sweden, Nokia from Finland, and Samsung from South Korea. but one company is way in the lead today as the world’s biggest supplier of networked telecommunications equipment. Huawei has been bidding for contracts around the world to set up 5g networks. but the Chinese company isn’t welcome in a lot of places; Australia New Zealand, Taiwan, and Japan have all blocked Huawei from building their 5g networks. so as the u.s. the Trump administration has even put pressure on the UK Poland and Germany to stop them from working with Huawei. there’s an obvious business reason for that Huawei has been crushing the competition and the Americans want in but the country’s shutting.
