I worked on Cingular Wireless' brand new National Networks team back in 2000-2004, where we ran their Nokia WAP Gateway and related upstream systems for years. A WAP gateway was essentially an HTTP proxy that translated UDP based WAP protocol from the flip phones into regular TCP based HTTP for browsing the web. These were the days when 9.6Kbps data connections was the best you could expect, so WAP was needed because it was far more efficient than HTTP. Once wireless networks reached 2G and got faster (eg 64 Kbps), cell phones and PDAs started including regular HTTP based web browsers, and WAP usage died quickly, or so I thought.
Wireless providers originally used WAP to create their own little "wall garden", where they could extract third party monies from content providers (eg. ESPN, Yahoo News) in exchange for getting on the main menu of all their customers. HTTP was designed to be decentralized, and once it took over, WAP provided no added value anymore. If we can kill Flash in 2020, why didn't we kill WAP 10-15 years ago, when the last 1G networks were phased out?
interestingly, now, in 2020, we're apparently back right where we started, with Google, Wechat, Facebook, and others locking everybody into their own much larger walled gardens, convincing us to prefer to stay within their "app" instead of freely browsing the open web. The content providers have focused on leveraging ad networks to track every single thing we do on the open web, in exchange for access to so-called "free" content. Information is king, more valuable to them than anything else.
Enough pontificating. Go back to Reddit, Facebook and Tik-tok and enjoy your self imposed prisons.
Peace out
