5G Requirements of ITU
As we are approaching towards 2020, it is likely that there will be more than 50 billion connected devices worldwide. The Internet of Things will be no longer just a concept we think about, in fact it will be all around us. Anything and everything from our home appliances to cars will be connected to the 5G network. 5G is a mobile technology that has the potential to completely change the way we interact with wireless devices, from the smartphones in our pockets to the smart appliances at home.
Not only will the connection density be high in 5G networks, but also the speed and capability for high-resolution real-time services will be much better in case of 5G networks. Protection of user data and battery-life saving will be other important aspects of 5G networks.
The International Telecommunication Union (ITU) is an organization that defines the performance requirements for 3G and 4G cellular technologies. Some of the examples of 5G requirements of ITU are listed below:
- The peak data rate is 20 Gbps for an indoor environment.
- The target for one-way latency between the radio network (e.g., a base station) and the user equipment is 1 ms.
- One million devices need to supported per square kilometer area in a dense environment.
- In an area with large density of wireless devices, the supportable throughput needs to be 10 Mbps per square meter.
- The wireless services experience of users should be maintained even at the speeds of 500 Km/h, which could be the speed of a bullet train.
There are various other fields which are being investigated by research organisations like mmWave (millimeter wave) technology, massive MIMO, dense networks (as compared to 4G), Cognitive radio technology etc.
