What is 5G?

5G Explained

5G is the fifth-generation technology standard for mobile networks and includes the following benefits:

  • Larger channels to increase speed
  • Lower latency to improve responsiveness
  • Support for more devices

Why 5G?

5G promises to deliver a greater capacity, lower latency, to serve a more diverse and larger range of client devices than cellular networks have ever done before. It does this based on three fundamental technologies to improve spectral efficiency:

  • 5G radio
  • Flexible core network architecture
  • Mobile edge computing, which moves resources from the core to closer to where data is consumed and generated

How does the network architecture change in 5G?

The core network architecture is a radical departure; its service-based interfaces replace the layer architecture of older networks with virtualization and network functions, replace dedicated hardware with technology agnostic interfaces, and allow devices to join a network via Wi-Fi or wired networks to access 5G services. This new direction by the 5G networks provides the flexibility that enterprise networks have today.

What are the main differences between 5G and Wi-Fi 6?

The main difference between 5G and Wi-Fi 6 isn’t performance, but how they’re deployed, who manages them, how much they cost, and whether or not they serve all clients currently in your network or only new clients with 5G radios and SIM cards.

How do 5G and Wi-Fi work together?

Both 5G and Wi-Fi were created to provide higher data rates, lower latency, and support for more devices and users. 5G and Wi-Fi complement each other and will continue to co-exist for the foreseeable future. Wi-Fi 6 (802.11ax) is ideal for indoor and enterprise applications and can provide a broad range of mobility between Wi-Fi and cellular. Both Wi-Fi and 5G can work together to increase productivity and enhance user experience in the hybrid workplace.

What is Aruba’s approach to 5G and Wi-Fi?

Aruba integrates cellular into the enterprise network. Aruba Air Pass™ enables Wi-Fi enabled devices with SIM credentials from major cellular network operators to automatically connect to enterprise networks. This improves the in-building cellular experience because Wi-Fi is automatically offloaded onto the enterprise network.

Using Air Pass, users can send and receive Wi-Fi calls and text messages, and the Wi-Fi network can deliver high-speed data offload. The combination of the Aruba Air Pass service, Passpoint authentication, and Wi-Fi Calling (WFC) ensures robust in-building and campus cellular coverage, delivered over Wi-Fi.

WFC allows IT departments to extract more return on investment from existing WLAN networks, address coverage problems, and increase capacity with minimal additional investment. Because Air Pass dramatically increases the attach rate of smartphone devices to the WLAN, it also enhances the Wi-Fi infrastructure as a sensor system. Applications such as shopper analytics, space and energy optimization, and network security systems have greater visibility into visitor data traffic, location, and behavior.

Aruba is also bringing Citizens Broadband Radio Service (CBRS) private LTE/5G networks to the enterprise, further validating that cellular technology is ready for widespread enterprise use. Celona, an exciting startup founded by former Aruba and Qualcomm veterans, built the first CBRS solution designed from the ground up to integrate seamlessly into enterprise networks. In the United States, CBRS will simplify the twin problems for private LTE networks: access to spectrum and consolidating multiple mobile network operators into a single-layer infrastructure.
