Video surveillance of remote substations represents another type of application, with a significantly higher bandwidth need. Metering devices, which already today are commonly deployed using wireless technologies, can also be a data source for the evolved power grid. Other than the PMUs, there could be sensors installed on different points in the grid to monitor the temperature, vibration and other physical characteristics of the devices in the grid. In this scenario, the frequency of sending data in this scenario is less compared to protection and also the demand for low latency is less strict however the need of time synchronisation, security and large-scale coverage becomes extremely important. PMUs for wide area monitoring of the voltage and current in the grid are used to detect faults in the grid. Monitoring includes monitoring of grid equipment, including real-time situational awareness and supervision of capacitor bank controllers, fault detectors, re-closers, switches, and voltage regulators within substations. 5G technology and IoT devices, together with deep learning algorithms, will connect distribution electricity systems with transmission electricity systems at the highest performance resolution and computational level regarding Big Data and digitalisation. Components & enablersĥG technologies is a fundamental layer in electricity power systems (Figure 1) that will enable IT-AM, WAMS and WAMPAC systems. 5G’s main characteristics are large bandwidth (> 1 Gb / s), high connection density, low latency (< 5 ms) and high connection reliability (99.99%). The primary 5G standards bodies involved in these processes are the 3rd Generation Partnership Project (3GPP), the Internet Engineering Task Force (IETF), and the International Telecommunication Union (ITU). With no firm 5G technology standard truly in place at this time, the market is still figuring out the essential 5G features and functionalities. 5G can support up to a million devices per square kilometre, whereas 4G supports only 4,000 devices per square kilometre. So the data speed for wireless broadband connections using 5G would be at a maximum of around 20 Gbps. The 5G wireless de-vices also have 4G LTE capabilities, as the new networks use 4G for initially establishing the connection with the cell, as well as in locations where 5G access is not available. In New York, a writer for Gizmodo topped out at 1.3 Gbps-fast enough, as he points out, to download an entire season of a Netflix series in under one minute.ġ Source: Global claim from May 2020, based on Opensignal independent analysis of mobile measurements recorded during the period January 31 – Ap© 2020 Opensignal Limited.Ģ Source: Based on analysis by Ookla® of Speedtest Intelligence® data of Verizon, T-Mobile and AT&T 5G median download speed results for Q2 2020 nationally.

Select members of the tech press have also been putting Verizon 5G Ultra Wideband to the test and have experienced its high speeds firsthand. In Minneapolis, Verizon 5G download speeds have been measured at 917.5% of Verizon 4G LTE speeds, while customers in Providence, R.I., have reached download speeds topping 1.13 Gbps, or 11 times faster than 4G LTE. Recent Speedtest Intelligence data recorded in Denver pegged Verizon 5G Ultra Wideband download speeds at 988.37 Mbps, an 820.2% improvement over LTE. In fact, Verizon 5G download speed in Chicago was so high that Francis Sideco, VP of technology at IHS Markit, observed that it was “the fastest speed we’ve ever recorded in the U.S. By analyzing a publicly available 5G dataset comprised of the channel, context, and cell-related metrics with throughput information, existing work has used. That means a user could download a 600MB video in about 34 seconds, compared to roughly 2.3 minutes on LTE. 2 According to a recent RootMetrics® report citing 5G Ultra Wideband coverage in Chicago, Verizon was the only carrier in any city to deliver a 5G maximum download speed faster than 1.0 gigabits per second, or Gbps, and Verizon's 5G median download speed was over four times faster than its non-5G coverage. 1 It's 11x faster than AT&T's 5G and 14x faster than T-Mobile's 5G Nationwide. Verizon 5G Ultra Wideband is the fastest 5G in the world.
