ITU issues draft specification 5g and accelerates the standardization process

With the publication of the draft expected to become the final specification of 5g by ITU, 5g has taken a big step forward in the process of standardization. The ITU draft text document contains 13 different indicators - if telecom companies want to call their next generation services "5g.".

According to the news on february27th, the requirement for connection is that each base station provides 20gbps downlink and 10Gbps uplink peak data rate. These requirements are relatively low for each user. The standard requires that each user can enjoy 100Mbps download speed and 50Mbps upload speed. Although this is not far from the speed that some operators see on LTE advanced networks, 5g connections are expected to be more consistent with less latency.

ITU also stated in the document that 5g hardware must support at least 1 million connection devices per square kilometer or about 0.38 square mile according to the official name of "imt-2020". 5g network should also provide users with a maximum delay of 4 ms, which is significantly lower than the level of LTE cell of 20 ms.

Other requirements include peak spectral efficiency specifications, or how many bits are transmitted per Hertz spectrum - the standard requires 30bits / Hz downlink and 15bits / Hz uplink. The document states that the standard also specifies an interrupt time - 0 milliseconds when moving between 5g cells.

Although this is a great progress in the process of 5g standardization, there is still a long way to go for full standardization, as the road map above clearly shows. The document is expected to be signed at the ITU-R research group 5 meeting in November this year. But a fully agreed definition of 5g and the start of a real business deployment are expected to wait until 2020. At that time, we will finally be able to answer the difficult question: how much will it cost you to get the privilege to connect to these newer, faster networks.
