what is 5G? confusion dont worry here is the article for you guys read all and be updated..
5G Is Real
Verizon Wireless has won the race to 5G—sort of. On October 1, Verizon launched its "5G" home service in Houston, Indianapolis, Los Angeles and Sacramento, establishing equivocal bragging rights and setting off a domino run of 5G network launches that will continue through next spring.
That first network isn't actually the real, global mobile standard for 5G. The first one of those will likely be AT&T's network, coming by the end of the year. (Verizon plans to switch to the global standard next year, swapping out equipment at no cost to existing customers.) This all means you're about to see the marketing for 5G get ramped up quite a lot, and so it's good to know what everyone's actually talking about.
5G stands for fifth-generation cellular wireless, and the initial standards for it were set at the end of 2017. But a standard doesn't mean that all 5G will work the same—or that we even know what applications 5G will enable. There will be slow but responsive 5G, and fast 5G with limited coverage. Let us take you down the 5G rabbit hole to give you a picture of what the upcoming 5G world will be like.
1G, 2G, 3G, 4G, 5G
The G in 5G means it's a generation of wireless technology. While most generations have technically been defined by their data transmission speeds, each has also been marked by a break in encoding methods, or "air interfaces," which make it incompatible with the previous generation.
1G was analog cellular. 2G technologies, such as CDMA, GSM, and TDMA, were the first generation of digital cellular technologies. 3G technologies, such as EVDO, HSPA, and UMTS, brought speeds from 200kbps to a few megabits per second. 4G technologies, such as WiMAX and LTE, were the next incompatible leap forward, and they are now scaling up to hundreds of megabits and even gigabit-level speeds.
5G brings three new aspects to the table: greater speed (to move more data), lower latency (to be more responsive), and the ability to connect a lot more devices at once (for sensors and smart devices).
The actual 5G radio system, known as 5G-NR, won't be compatible with 4G. But all 5G devices, initially, will need 4G because they'll lean on it to make initial connections before trading up to 5G where it's available.
Introducing 5G networks – Characteristics and usages
The next generation telecom networks (5G) will hit the market by 2020. Beyond just speed improvements, 5G is expected to unleash a massive IoT ecosystem where networks can serve communication needs for billions of connected devices, with the right trade-offs between speed, latency and cost.

A NEW TRUST MODEL FOR THE 5G ERA
5G use cases will bring new requirements on the storage, compute and network domains and will introduce new risks to the confidentiality, integrity and availability of enterprise & user data. This White Paper provides Gemalto’s recommendations to address these new challenges and build a new trust model for the 5G era.

What is (and what is n’t) 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.
