RE: What happened to WAP
Oops a false move made me send my mail without finishing it (the damn Ctrl+Return shortcut effect). To end the 7) Technical problems paragraph : One should therefore not point finger at the WAP Forum and tell them "WAP is dead because you wanted to build your technology alone without involving the W3C or others, so you're paying the price of your arrogance". Whatever the technology used, be it WAP, lightweith HTML, XHTML or cHTML (in i-Mode), development for phones require a specific application with dedicated ergonomics, special navigation mode and so on. This, combined with the fact that lots of already existing web sites or web application are badly written, mixing presentation with business logic, made the cost of developing a WAP application too high. Add a bit of market specifics, especially the impossibility to have a decent revenue model due to the short sightedness of mobile operators which would not want to share their revenues, and the fact that the market has become saturated so the deployment of new phones has dramatically slowed down, and you obtain WAP as it is known now. 8) The success of SMS While WAP stagnated, a low-tech player developped and boomed : SMS. This asynchronous, two-way, short message (160 characters) delivery system is generating high revenues for operators (in France, about 10% of the revenue of mobile operator come from SMS, and this share is growing). Why does a very low-tech, poor media technology (SMS can be used to download custom ringtones and screen logos) succeeds where WAP has failed ? Simply because all GSM handsets can receive SMS messages, that the charges are high but per-message (and not per-time), because it is lucrative (mainly for the mobile operators, but the SMS Premium charging system will allow content provider to receive a share of the revenue), and because there are killer apps that advertised the technology to the masses : chat, games, and custome ringtones & logo download for now (it looks stupid, but a lots of revenue is generated with these three apps). Revenue is a great incentive for content providers, so the content quality is slowly but steadily increasing, et voila, you've got a prosperous industry. 9) Conclusion To conclude, we should not look at pure technical reasons to explain the demise of WAP. The problem is mainly rooted in the dynamics of the mobile phone market. So will be the solution, because even if WAP looks dead, it is not. As I've said at the beginning of this mail (the previous one, in fact), there is a majority of WAP 1.2 or WAP 2.0 enabled phones coming on the market now. By creating the SMS Premium revenue sharing scheme, the mobile operators seem to have eventually understood that revenue sharing is the best way to create a market (or at least, they remembered the Minitel lesson). Without revenue sharing, it was virtually impossible to make money on the WAP market. With higher bandwidth and volume charging rather than time charging, we can expect the advertisement market to appear. With advertisement and revenue sharing, we can expect the WAP market to become lucrative, and hence become a support for the technology instead of a dead-end.
