Hello Kitty's Revenge
Early this year, there was some comment in the open press concluding that the US was the world’s leading source of wireless innovation and technology expertise (“Europe Had Decisive Wireless Lead, But Lost It to US With Poor Moves”). Well, the good news is that finding some of those smaller, innovative creators of made-right-here-in-Japan, ready-to-be-exported mobile technology is getting an awful lot easier. We spent yesterday at Sun’s JavaOne conference in Yokohama, and there was an interesting line-up of companies displaying their wares on the showroom floor.
WWJ has been focusing on mobile Java for the past few weeks — and with good reason. The pundits claim the interactivity and secure mobile execution environment provided by Java could be vital for making 3G data services pay off sooner rather than later. We visited then-pre-IPO software developer Net Village, creator of the “Remote Mail” Java-based mail appli. A couple of key facts emerged: Java boosts packet revenue for the carriers, the cost and complexity of deploying sophisticated Java applis may be beyond what the carriers themselves can do (economically), and Remote Mail is one cool app — 330,000 happy users can’t all be wrong! (See a live demo.) Oh — and NV’s IPO generated a modest 4.094 billion yen.
There’s a tremendous amount of initial wireless LAN network activity going on in Japan right now, but it’s still too early to say how WLAN will affect 3G. One thing is certain however: licensed-spectrum carriers are looking closely at WLAN to determine whether the technology will disrupt their carefully knit 3G network, wireless Internet, and data revenue plans. We speak with an industry insider on a recent WLAN hotspot trial conducted by a major mobile telco. But large carriers and others thinking about launching hotspot networks shouldn’t worry about finding content. First, solve the billing, roaming, and security problems — then content providers will beat a path to your door… just as happened with, oh…, for example, i-mode. 
Dr. Masayuki Fujise from Yokosuka Research Park’s Communications Research Labs talks about the Intelligent Transport System and a fiber-optic-based road-to-vehicle wireless system that will stream multi-megabyte files to your car in under 10 minutes.
