Reader, Tamia Boyden asks this question:

In the 90s, how could we access the internet without WiFi?

This post began as an answer to that question at Quora. In the process of answering, I compiled this history of public, residential Internet access. Whether you lived through this fascinating social and technical upheaval or simply want to explore the roots of a booming social phenomenon, I hope you will find the timeline and evolution as interesting as I do.

I have included my answer to Tamia’s question, below. But first, let’s get a quick snapshot of the highlights. This short bullet-list focuses on technical milestones, but the history below, explains the context, social phenomenon and implications.

As with many of my recent posts, this was originally a reply to a member of Quora, a Q&A web forum. But, it fits within Lifeboat’s educational mission and our fascination to push the limits of creativity and tech.

Is there a theoretical speed limit to WiFi devices over the next 10 years?

Because of four recent practices,* it is difficult to predict an upper limit for future overall throughput:

  1. Channel bonding
  2. Beam steering (MIMO shaping and directing the antenna pattern)
  3. Mesh Networking (i.e. subdividing a service area into micro-cells). Residential examples: Google WiFi, Netgear Orbi or TP-Link Deco
  4. Ultra wideband or Ultra-high frequency: In 2017, both Netgear and Asus introduced routers with 802.11ad WiFi (‘WiFi AD’). Although it still not widely adopted, it adds a 60 GHz radio to the existing 2.4 and 5 GHz radios, supporting 7 Gbps network speed).
