With 4G systems being deployed across the Globe, all eyes are on development of 5G technology. The new 5G technologies will need to be chosen developed and perfected to enable timely and reliable deployment. The new 5th generation, 5G technology for cellular systems will probably start to come to fruition around 2020 with deployment following on afterwards.
So, it’s time to understand what 5G Network really is –
5G is the coming fifth-generation wireless broadband technology based on the IEEE 802.11ac standard. It will provide better speeds and coverage than the current 4G, operates on 5 GHz signal and offers speeds of up to 1 Gb/s for tens of connections.5G is a packet switched wireless system with wide area coverage and high throughput.5G wireless uses OFDM and millimeter wireless and is going to be a packed based network.

To meet the preceding requirements, 5G should have the following performance advantages over existing mobile communication technologies:
- 100 billion connections
- 1 ms latency
- 10 Gbps throughput
According to the Groupe Speciale Mobile Association (GSMA) to qualify for a 5G a connection should meet most of these eight criteria –
- One to 10Gbps connections to end points in the field
- One millisecond end-to-end round trip delay
- 1000x bandwidth per unit area
- 10 to 100x number of connected devices
- (Perception of) 99.999 percent availability
- (Perception of) 100 percent coverage
- 90 percent reduction in network energy usage
- Up to ten year battery life for low power, machine-type devices
5 G will benefit the end users in following ways –
- Faster Data Speeds: Currently, 4G networks are capable of achieving peak download speeds of 1 Gbps. With 5G, this would increase to 10Gbps.
- Ultra-low latency: Currently with 4G, the latency rate is around 50 milliseconds, but 5G will reduce that to about one millisecond. This will be particularly important for industrial applications and driverless cars.
- “Connected world”: The Internet of Things (wearables, smart home appliances, connected cars) is expected to grow exponentially over the next 10 years, and it will need a network that can accommodate billions of connected devices. 5G is designed to cater this capacity, and also to be able to assign bandwidth depending on the needs of the application and user.
