Which type of wireless technology are you using for the communication and the internet? Are you using the latest 4G(LTE), or you are still using 3G or maybe 2G. A big thanks to JIO to provide high-speed wireless communication in India at a very cheap rate. In this article, I’ll discuss the next iteration of wireless communication i.e. 5G which would be deployed in India by 2020. So without any further ado, let’s get started.
What is 5G?
5G or Fifth-generation wireless is the latest iteration of cellular technology, engineered to greatly increase the speed and responsiveness of wireless networks. With 5G, data transmitted over wireless broadband connections could travel at rates as high as 20 Gbps.
5G will also enable a sharp increase in the amount of data transmitted over wireless systems due to more available bandwidth and advanced antenna technology.
In addition to improvements in speed, capacity, and latency, 5G offers network management features, among them network slicing, which allows mobile operators to create multiple virtual networks within a single physical 5G network.
This capability will enable wireless network connections to support specific uses or business cases and could be sold on an as-a-service basis. For example, A self-driving car would require a network slice that offers extremely fast, low-latency connections so a vehicle could navigate in real time.
How does it work?
Wireless networks are composed of cell sites divided into sectors that send data through radio waves. Fourth-generation (4G) Long-Term Evolution (LTE) wireless technology provides the foundation for 5G.
Unlike 4G, which requires large, high-power cell towers to radiate signals over longer distances, 5G wireless signals will be transmitted via large numbers of small cell stations located in places like light poles or building roofs.
The use of multiple small cells is necessary because the millimeter wave spectrum – the band of spectrum between 30 GHz and 300 GHz that 5G relies on to generate high speeds – can only travel over short distances and is subject to interference from weather and physical obstacles, like buildings.
On which frequency does it operate?
Low-frequency 5G networks, which use existing cellular and Wi-Fi bands, take advantage of more flexible encoding and bigger channel sizes to achieve speeds 25-50% better than LTE, according to a presentation by T-Mobile exec Karri Kuoppamaki.
Those networks can cover the same distances as existing cellular networks and generally won’t need additional cell sites. The real 5G innovation is happening at higher frequencies, known as millimeter wave. Down in the existing cellular bands, only relatively narrow channels are available because that spectrum is so busy and heavily used.
Millimeter wave signals also drop off faster with distance than lower-frequency signals do, and the massive amount of data they transfer will require more connections to the landline Internet.
So cellular providers will have to install more, smaller, lower-power base stations rather than use existing powerful macrocells to offer the multi-gigabit speeds that millimeter wave networks promise.
What is the status of 5G deployment in the world as well as in India?
Wireless network operators in four countries – the United States, Japan, South Korea, and China – are largely driving the first 5G buildouts. Network operators are expected to spend billions of dollars on 5G capital expenses through 2030, according to Technology Business Research Inc.
India has also announced the deployment of 5G services by 2020 and within the 2 years of time span the 5G services will deploy around the whole country, just like 4G services.
The 5G radio system isn’t compatible with 4G radios, but network operators that have purchased wireless radios recently may be able to upgrade to the new 5G system via software rather than buying new equipment.
By 2030, 5G services will become mainstream and are expected to range from the delivery of virtual reality (VR) content to autonomous vehicle navigation enabled by real-time communications (RTC) capabilities.
What types of 5G wireless services will be available?
Network operators are developing two types of 5G services.
1: 5G fixed wireless broadband services: It deliver internet access to homes and businesses without a wired connection to the premises. To do that, network operators deploy NRs in small cell sites near buildings to beam a signal to a receiver on a rooftop or a windowsill that is amplified within the premises.
Fixed broadband services are expected to make it less expensive for operators to deliver broadband services to homes and businesses because operators need only install fiber optics to cell sites, and customers receive broadband services through wireless modems located in their residences or businesses.
2:5G cellular services: It will provide user access to operators 5G cellular networks. These services will begin to be rolled out in 2019 when the 5G-enabled devices are expected to become commercially available. Cellular service delivery is also dependent upon the completion of mobile core standards by 3GPP in late 2018 or in 2019.
Some key specifications of 5G technology
- Up to 10Gbps data rate – > 10 to 100x improvement over 4G and 4.5G networks.
- 1-millisecond latency.
- 1000x bandwidth per unit area.
- Up to 100x number of connected devices per unit area (compared with 4G LTE) 99.999% availability.
- 90% reduction in network energy usage.
- Up to 10-year battery life for low power IoT devices.
