5G Explained re-post

immi007 — Sat, 29 Feb 2020 05:53:51 GMT

What is 5G?

5G is the next generation of mobile broadband that will eventually replace, or at least augment, your 4G LTE connection. With 5G, you’ll see exponentially faster download and upload speeds. Latency, or the time it takes devices to communicate with wireless networks, will also drastically decrease.

How does 5G work?

By gsma/itu

Unlike LTE, 5G operates on three different spectrum bands. While this may not seem important, it will have a dramatic effect on your everyday use.

Low-band spectrum can also be described as sub 1GHz spectrum. It’s the primary band used by carriers for LTE, and bandwidth is nearly depleted. While low-band spectrum offers great coverage area and wall penetration, there is a big drawback: Peak data speeds will top out around 100Mbps.

Mid-band spectrum provides faster speeds and lower latency than low-band. It does, however, fail to penetrate buildings as effectively as low-band spectrum. Expect peak speeds up to 1Gbps on mid-band spectrum.

High-band spectrum is what delivers the highest performance for 5G, but with major weaknesses. It is often referred to as mmWave. High-band spectrum can offer peak speeds up to 10Gbps and has extremely low latency. The main drawback of high-band is that it has low coverage area and building penetration is poor.

What can 5G do?

Improve broadband

The shift to 5G will undoubtedly change the way we interact with technology on a day-to-day basis, but it’s also an absolute necessity if we want to continue using mobile broadband.

Autonomous vehicles

In the future, your vehicle will communicate with other vehicles on the road, provide information to other cars about road conditions, and offer performance information to drivers and automakers. If a car brakes quickly up ahead, yours may learn about it immediately and preemptively brake as well, preventing a collision. This kind of vehicle-to-vehicle communication could ultimately save thousands of lives.

Public safety and infrastructure

5G will allow cities and other municipalities to operate more efficiently. Utility companies will be able easily track usage remotely, sensors can notify public works departments when drains flood or streetlights go out, and municipalities will be able to quickly and inexpensively install surveillance cameras.

Health care

The ultra-reliable low latency communications (URLLC) component of 5G could fundamentally change health care. Since URLLC reduces 5G latency even further than what you’ll see with enhanced mobile broadband, a world of new possibilities opens up. Expect to see improvements in telemedicine, remote recovery, and physical therapy via AR, precision surgery, and even remote surgery in the coming years.

IoT

One of the most exciting and crucial aspects of 5G is its effect on the Internet of Things. While we currently have sensors that can communicate with each other, they tend to require a lot of resources and are quickly depleting LTE data capacity.

Where is 5G now?

when should you expect to see 5G in your neighborhood?

Well, it depends on the neighborhood and country you live in.

In India plans are for 2022 rollout. Might get delayed to 2023.

What 5G phones are available and should you buy one?

Although 5G will undoubtedly change the way we interact with each other and consume media, the change won’t happen overnight. It will be a few years before 5G is up and running smoothly

ultimately a personal decision, it may be wise to hold off on buying a 5G handset in 2020, especially considering the fact that a slew of manufacturers are expected to release 5G-capable handsets this year.

as I think one possibility in 5g is autonomous driving as I need it most because I sometimes lose control while driving a car and sometimes lost my mind while driving

aslo I wanted an eco system for the working of smart devices as of currently I dont have any but in future I will take up robots and employ them for my house hold work I wanted to get rid of Manuel work like cleaning house , door unlock, car automatically drives, and cooking and washing clothes through the ecosystem

but on the point 5g phones have lots of compromises

Re: Re: 5G Explained re-post

immi007 — Sat, 29 Feb 2020 06:03:51 GMT

yes, they require line of sight to work which is almost not possible in India

Re: Re: 5G Explained re-post

immi007 — Sat, 29 Feb 2020 06:08:52 GMT

yes, Nice ideas. i want robots to clean house especially, also dishes. door unlock already available i guess but expensive. cooking, washing clothes are good ones, also organising or sorting things in desk etc.

autonomous driving is difficult in India, it requires white colour paint on roads. road lanes, dotted line, it's a challenge for any company to make autonomous car for India.
Yes in India autonomous cars will on click if they release mid range cars and suv like one.

yes that I know company is needed to make SUV style autonomous vehicles for driving in india although cars like Tesla, Mercedes, and all the other flagship cars have autonomous driving in india

in mid range cars we have automatic gear shifting
as of now

5g will only help in mapping the cars internal navigation system like the car maps rest

the autonomous driving cars
have radar sensors, ultra sonic sounds to capture and see the surrounding and surface, the the autonomous driving could be successful in India when mid ranger cars launch the autonomous driving in SUV, sedan , nano type cars

5g will only help the cars to determine the location of the car and help the cars to navigate but rest the autonomous driving is dependent on the inbuilt sensors like

radar, ulra sonic waves , 3d depth sensors camera , high resolution camera which I think it won't require a net connection or even 5g

and I dont think that's challenging to have autonomous vehicles because autonomous driving not only requires 5g but also needs sensors as well when flagship cars are having autonomous vehicles in india then it won't be any difficulty for providing autonomous driving in mid rangers

but here's the catch our vehicle minster Nitin Gadkari is not allowing the autonomous vehicles even for the mid range car he says that it will lead unemployment in large scale although point is fair but it shouldn't be applied on private vehicles

Sensors are used to know the surroundings, but lane shifting is done using those white lines in Tesla and also most of the autonomous cars. 5G helps to communicate with other cars on road to safe travel.

In India roads are not good so when you need a autonomous car to change lanes or overtake other car or take a turn , it needs white paint on road for lanes . In India autonomous driving will only be limited i guess.

Re: Re: 5G Explained re-post

immi007 — Sat, 29 Feb 2020 06:36:18 GMT

yes, sensors are needed and that will increase the price of the vehicle which means mid range vehicle is difficult to make. you are right flagships don't sell that much . also even if jobs are lost, interesting jobs like designing autonomous car, services for them, etc jobs will increase.

here watch this video
it will help you to better understand
this driver is India and the the road is Punjab highway I guess so

Wait, automatic doors and automatic dishwashers are common.

yes that I know but they are too expensive or may be we dont have knowledge or a may be there are not available yet

although automatic door I have seen so far are in the malls and elevators 😅
