What Are 5G Speeds?

5G is capable of ultra-low latency rates that are less than 10 milliseconds, which means 5G latency is lower than 4G latency by a factor of 60 to 120.

Most practical low-latency capabilities require a geo-distributed network architecture that positions 5G core functions and services closer to end users. This is accomplished through a distributed, cloud-native 5G core and edge computing.

In some countries where 5G is available, 5G speeds for downloads are faster than those offered by Wi-Fi. That's because 5G operates on spectrum licensed to individual carriers and carries a relatively strong signal. Wi-Fi operates on unlicensed spectrum that is free for all, but it has a relatively weak signal and uses shared spectrum.

Because of its faster speeds and low latency, 5G also has a greater capacity to support real-time applications such as virtual reality, autonomous vehicles, and most IoT-connected devices.

5G networks can reduce congestion on mobile networks due to their faster speeds and lower latency. This improvement is reflected in technology improvements across the entire network (for example, IP/Optical transport, edge, core, automation). Also, a 5G radio can support more end devices than a 4G radio.

For locations that are not wired for broadband internet or covered by Wi-Fi, such as rural areas, 5G offers a solution for connecting to high-quality and high-speed internet service.

5G uses less physical infrastructure than other mobile networks; coverage can quickly be brought to any location by plugging in a 5G router. However, a carrier's ability to expand mobile coverage in any area using 5G will depend on how it deploys the technology.

5G can provide the bandwidth, low latency, and even power management to assist IoT devices to perform better and longer. Also, carriers will be able to offer private networks and/or a similar service through network slicing. Both private networks and network slicing can allow businesses to get different levels of connectivity from their service provider to accommodate multiple use cases for the IoT. 

Examples of services enabled through a network slice include:

• Enhanced mobile broadband (eMBB):
  eMBB provides higher bandwidth—and therefore, higher speeds—for everything from smart city applications and stadiums, to streaming infotainment in cars and planes, to seamless cloud services and fleet management telematics for safety and diagnostics.
• Ultra-reliable low-latency communication (URLLC):
  URLLC can support real-time, mission-critical communications like autonomous driving, industrial robotics automation, and emergency disaster response and location services. The tactile response time with URLLC is expected to be less than 1 millisecond.
• Massive Internet of Things (mIoT):
  MIoT can serve billions of low-cost, long-range, and ultra-energy efficient connected devices across remote locations, as well as cloud applications with periodic, infrequent communication.

Companies wanting to take full advantage of 5G speeds and other benefits will need industrial IoT networking devices capable of evolving to the 5G connectivity spectrum to cover diverse use cases. An example of such a device is a modular, industrial router that can support both cellular and low-power connectivity and extend secure, reliable enterprise networking from the factory floor to remote outdoor sites.

Scale will be another challenge for companies to address with 5G and the IoT. Managing thousands or even millions of connected devices will require automation tools for zero-touch deployment, and centralized control to simplify network management. 

5G speeds and other benefits, like low latency, make 5G technology well suited to support IoT-connected devices and applications. Here are just two examples of potential IoT use cases for 5G:

Healthcare

Technology tools like wearables have become important aspects of high-quality medical care, and 5G is likely to play an ever-increasing role in optimizing the performance of these devices and others. Investing in 5G can help healthcare teams work more efficiently and optimize operations for better information sharing.

Smart cities

Today's cities have thousands of cameras deployed using fiber and 4G LTE connections, and 5G will only enhance their capabilities. The low latency of 5G has implications for video-as-a-sensor technology, which can be used for crowd monitoring, asset utilization, parking space monitoring, traffic analysis, and pedestrian safety.

Also, how first responders use video can be improved with 5G speeds. With 5G, video can turn into a real-time tactical feed, enabling someone at a central location to coordinate with officers in real time, improving situational awareness for everyone. Drones can also share that information when launched from a tactical vehicle.

5G speeds and other benefits of 5G technology can't be fully utilized to deliver new services and support IoT use cases like those described above without the support of a service-centric network.

A service-centric network provides the flexibility and control to build differentiated services, rapidly deliver them to customers, and manage them end to end across both wireless and wireline domains. The key steps to evolving toward this type of network are:

• Implementing next-generation IP-based traffic handling
• Extending IP all the way to endpoints
• Laying the foundation for end-to-end automation
• Application-awareness and identity management to uphold service-level agreements for devices and services

Next-generation services will take advantage of the improved bandwidth and density of 5G technology and, of course, ultra-fast 5G speeds. These services are enabled by the ability to create custom virtual networks tuned to the needs of the services running across them.

With a service-centric network, organizations can tailor traffic handling end to end on a per-flow basis and deliver many types of differentiated services over the same infrastructure. And they can do it efficiently through end-to-end automation.
