问答题The tiny Isle of Man in the Irish Sea is not known as a vanguard of technology, but this month it was to serve as the test bed for the highly acclaimed third-generation mobile phones.

BT postponed the trial until late summer, after a similar delay announced a few weeks earlier by NTT DoCoMo in Japan. What’s the big deal? Aren’t thousands of mobile calls “handed off” every day from one “cell” to another without a glitch? They are indeed. But third-generation technology, or 3G, is so radically new that it requires a rethinking of just about every aspect of how mobile phones work, from the handset to the transmission masts to the software that runs them.

This creates the impression of an Internet connection’s being”always on,” which is good news. But keeping rack of these data bundles from one region to the next is a daunting engineering problem — and, more to the point, a brand-new one. NEC, the Japanese phone company that supplies BT with equipment for its Isle of Man trail, hasn’t had time to work it out. Handset makers also have work to do. The 3G technologies have so many features; only a wonder gizmo could handle all of them, which is why none exists. The phones are not only supposed to work with 3G networks but also with the less sophisticated ( but cheaper and more useful) General Packet Radio Service (GPRS) technology already being installed on the continent and also with the current mobile phone standard, Global System for Mobile (GSM).

Doing all this requires powerful, custom-built computer chips, which are tough to make quickly. A device that does so many things is bound to guzzle a lot of power.

Batteries that can keep a conventional phone running for days would fizzle in a 3G handset in a matter of minutes. Engineers are searching for alternative, but at the moment the lack of a long-lasting battery is a major hurdle. None of these problems is insurmountable, but neither will they be resolved quickly. Analysts at Forrester Research in the Netherlands predict that even in 2005, when more than half of Europe’s phones will be connected to the Internet, fewer than 15 percent of them will use 3G.

问答题One Number Gets It All—Phone, Fax or Voice Mail Tired of having to remember different numbers for your office phone, fax, pager or mobile phone? No room on your business card for the raft of numbers that are now part of everyday business contacts? The answer is at hand—or rather in a number. One number can now be used for all your different devices and communications, thanks to a new system devised by a technology company which uses the science available in the high-growth, hi-tech modem world. Instead of numbers belonging to different devices, the company assigns you one number belonging to you, the person. You have one number for phone, fax, pagers and mobile phones. All your calls and contacts come to this one number so that you can divert unwanted callers politely to your voice mail if you want. Voice messages that come into the same personal number can be turned into emails for delivery to the desktop of your computer or to another person’s computer. You can have trouble-free call-forwarding anywhere in the world. Those are some of the features of Bloodhound, a new service offered by Auckland-based computer telephony integrator—Powercall Technologies Ltd. General manager Nick Little said the company, a subsidiary of the Brocker Technology Group, came to the new one-number system when they wanted to set up in a new office. It would have cost $US 250 (RMB ￥2,000) a month to lease a small phone switchboard. To avoid the capital outlay or the hardware in the office, they set out instead to develop a switchboard based on a PC computer. Then, realizing the market was awash in such products, the company looked at ways to use its experience in voice mail, interactive voice response and unified messaging to develop new subscriber-based services. Mr. Little said Bloodhound, which costs $US 20 (RMB ￥160) a month for full phone, fax and messaging, side-stepped the number portability issue (whether phone owners can use the same number in different phone company systems or not) because subscribers were given not a telephone number, but their own personal number. “The number we issue is a virtual number belonging to the person. It does not terminate on a physical device, Mr. Little said. The subscriber sets up devices behind the scenes. Bloodhound runs on NT servers and subscribers pay their telephone carriers for line connection and any toll charges. They also pay for calls received on mobile phones via Bloodhound at US$ 25c (RMB ￥2) a minute. But they can change phone carrier company or exchange without having to change all their stationery. Callers are greeted by an automated virtual assistant, which locates the Bloodhound subscriber or takes messages. Calls can be screened, with known callers announced to the subscriber who can choose to accept a call or divert it to another person or voice mail. Fax can be forwarded to any location for printing, without the cellular charges associated with cellphone-based fax services. And if users have a sudden inspiration, they can call Bloodhound and dictate a message for recall later. Simon Morgan from advertising and direct marketing agency Carpe Diem has been a pilot user of the service throughout the year 2000. He said Bloodhound helped his five-person company present a consistent and professional face to the world. One of our staff works from home part-time, but with a Bloodhound number available to the world as her office number. As far as the world is connected, she works in the office. It’s also useful if I’m working at a client site. I can use the ‘I am Here’ feature and get calls forwarded through.
