In the ever-growing world of technology, the new most talked about thing is 5G. Every decade has envisioned a significant improvement in quality and coverage. The vision of 5G is about connecting the world to the Internet and the things. Blazing fast response and the instantaneous connection will be on priority. 4G has already revolutionised the arena of networking with improved speed and the higher call quality, 5G is indeed a big step ahead.
EVOLUTION OF NETWORK SIGNALS:-
1G– The first generation of communication network first rolled out in Japan in 1979. It used analogue signals for transmission. Due to lack of encryption, these calls were susceptible to be traced and frequent interference of radio signals were observed. only phone calls were possible on the network.
2G– The next evolution came in 1991 when the digital signals were started to be used. along with phone calls, SMS(short messaging service) were enabled. with the arrival of GPRS(general packet radio service)in 1997 exchange of emails on the go was made available.
3G– A big leap was made with the arrival of 3G in the 2000s. use of more data at faster speed opened the facility of making video calls, surfing internet and streaming videos. latency became considerably low at 100ms. Contemporary social media sites engraved the path to the more socially connected world. HSPA(high-speed packet access) signals were used which enabled a speed of around 3-8 Mbps.
4G– The fourth-generation proved to be revolutionary in an era of technology. Much faster speed and ability to stream high-quality videos brought the world into the pocket of people. latency became as low as 30ms which gave a speed of around 100-200 Mbps by using LTE(long term evolution) signals.
5G– The next big thing is the fifth generation which started to roll out in late 2020. The blazing fast speed of around 1GBps and super-low latency of around 1ms will make sure the connectivity remain intact and work without any hiccup.
HOW DOES IT WORK:-
The operational mechanism of 5G is also similar to its recent predecessors. It will start to operate in phased manner .initially the 5G will work in conjunction with 4G network. receptors in the receiver modem are designed such that 4G signal will be used for stability alongside 5G signal providing the quicker speed.
We currently use the sub 6Ghz frequency bands to operate the network signals .it is planned to use mm waves(26-30 GHz) for the uninterrupted blazing-fast 1GBps speed. Since the mm waves are short waves their range is narrow, MIMO (multiple input multiple out) devices will be used to suffice the lack of coverage.
