Mobile Wireless Technology
The new 5G technologies is to develop in the world as the fastest and latest technology in the telecommunication world.
The 5G generation technology for cellular systems will probably start to come to around in 2021.
1. 1G:First technology
phones were analogue and were the first mobile or cellular phones to be used. Although revolutionary in their time they offered very low levels of spectrum efficiency and security.
2. 2G: Second technology
This technologies were based around digital technology and offered much better spectrum efficiency, security and new features such as text messages and low data rate communications
3. 3G: Third technology
This technology was to provide high speed data. The original technology was enhanced to allow data up to 14 Mbps and more.
4. 4G: Fourth technology
This generation all-IP based technology capable of providing data rates up to 1 Gbps.
5. 5G: Fifth technology
One of the big challenges facing 5G is standardization. There are already multiple groups working to come up with standards around interoperability, backward compatibility with older technologies (4G, 3G), and making sure the network will be future-proof. While many companies agree that a global standard is needed Building the infrastructure for 5G is also a huge task, with issues around spectrum and installing new antennas. 5G is likely going to rely, at least in part, on higher-frequency bands. There is more space in those airwaves available, but at such high frequencies, signals can’t travel nearly as far as they can over the frequencies used for 4G, resulting in a poor connection
One major enabler for 5G will be the release of frequency spectrum and this needs to be managed on a global scale to ensure commonality and also the reduction of interference between services, especially those operating globally. This process is managed under the auspices of the International Telecommunications Union, ITU.
5G Creating new communication
The future of mobile communications is likely to be very different to that which we are used to today. While demand for mobile broadband will continue to increase, largely driven by ultra high definition video and better screens, we are already seeing the growing impact of the human possibilities of technology as the things around us become ever more connected.
