5G Specs Announced: 20Gbps Download, 1ms Latency, 1m Devices per Square Km

Companies such as Nokia and Samsung have only reached 10Gbps and 7.5Gbps downlink speeds in their current 5G network tests, but the International Telecommunications Union (ITU) is taking things to the extreme by dictating that download speeds for a single 5G cell should reach 20Gbps. Real-world data rate, however, should see download speeds of 100Mbps and upload speeds of 50Mbps.

The total download capacity for a single 5G cell must be at least 20Gbps, the International Telecommunications Union (ITU) has decided. In contrast, the peak data rate for current LTE cells is about 1Gbps. The incoming 5G standard must also support up to 1 million connected devices per square kilometer, and the standard will require carriers to have at least 100MHz of free spectrum, scaling up to 1GHz where feasible. These requirements come from the ITU's draft report on the technical requirements for IMT-2020 (aka 5G) radio interfaces, which was published Thursday. The document is technically just a draft at this point, but that's underselling its significance: it will likely be approved and finalized in November this year, at which point work begins in earnest on building 5G tech.
