There has always been an improvement in the wireless data transfer technology. After the release of 4G which has now become normally used by many people, comes the next generation of wireless data transfer technology, the fifth generation, 5G, which is already being tested now and will be into use by the next year.
The name and official logo of 5G was done by 3GPP cellular standards group and was told that 5G will be IoT based. Further specification was given by the International Telecommunication Union (ITU) for the network to act as the next generation, 5G.
The minimum requirements for peak data rates, spectral efficiencies and target value for both uplink and downlink was listed by the ITU. The list consisted of:
- Downlink peak data rate is 20Gbps
- Uplink peak data rate is 10Gbps
- Downlink peak spectral efficiency is 30 bits per second per Hz
- Uplink peak spectral efficiency is 15 bits per second per Hz
- Downlink user experienced data rate is 100Mbps
- Uplink user experienced data rate is 50Mbps
The spec list also include the following criterias. Compared to 4G, 5G should have significant 20Gbps download capacity. The report also states that, IMT-2020, or 5G, must support at least 1 million connected devices per square kilometre, for the purpose of IoT. 5G will require carriers to have at least 100MHz of free spectrum, and up to 1GHz were available. The 5G should have base stations that can support access from 0kmph up to 500kmph vehicular speed.
The 4th gen LTE networks offer 20ms Latency so, 5th gen networks are expected to offer 4ms Latency. Ultra reliable low latency communications (URLLC) will be given latency upto 1ms by the fifth gen networks. The ITU report and specs will be finalised before the work for building 5G technology begins, later this year. The leading companies like Verizon, AT&T, Intel, and Qualcomm have already begun testing 5G technology with technical assistance from other groups.
