2020: Too Much and Not Enough

By Cambium Networks

“I have five people in the house at the moment, four of which will be streaming full HD resolution video, three simultaneously online gaming, online music, Zoom and Teams meetings in parallel while I try to work and host meetings without interruptions!” Sound Familiar? This is home life for many people now.

The numbers add up to increased demand:

  • Netflix says you need 10 Mbps to stream full HD content and 25 Mbps for 4K Ultra HD content. Clearly the more streams you want it multiplies up.
  • Gaming platform Twitch needs ~6 Mbps dedicated for full HD resolution (1080p, 60fps).

Imagine having the ability to simultaneously run multiple businesses, multiple classrooms and manage daily life simultaneously with no hassle – in your home. The multi-gigabit speeds of millimeter wave wireless communications make this possible. To do so, you need high capacity connectivity in long distance backhaul, wide area network (WAN) distribution and indoor Wi-Fi access to deal with this huge increase in demand.

60 GHz millimeter wave technology offers not only access to the house but distribution throughout the neighborhood to each house via a Mesh network. Paired with a high-capacity Wi-Fi 6 access point you can not only provide access but mobile connectivity through hotspots allowing you to reach dispersed areas.

The 802.11ay standard is almost here for fixed wireless products operating in the 60 GHz millimeter wave spectrum, enabling multi-gigabit wireless connectivity. This delivers unprecedented speeds for wireless connectivity at a fraction of the time, cost and hassle of deploying fiber.

Recently, David Botha, OEM Partnership Manager of Facebook Connectivity and the Cambium product management team explored the 60 GHz opportunities for service providers. Their discussion detailed four key technical advantages of the 802.11ay standard.

  1. Higher capacity – With channel bonding technology, 802.11ay in effect doubles the channel size to 4.32 GHz, which supports up to 9,240 Mbps PHY throughput.
  2. Synchronization – 802.11ay is based on TDMA/TDD channel access with network synchronization, which is preferred for outdoor fixed wireless applications because the synchronized system reduces interface and maximizes frequency reuse.
  3. More client nodes – 802.11ay supports 15 client nodes per sector, which is a significant increase from 8 client nodes supported in the 802.11ad standard.
  4. Meshing architecture – The solution incorporates highly efficient Terragraph meshing technology to provide a highly reliable and flexible Layer 3 architecture to facilitate network design and deployment.
