Launched in the capitals of tech-savvy Sweden and Norway in December, fourth generation wireless technology is getting off to a slow start in Scandinavia, analysts say.

They think it is still a couple of years away from overcoming the obstacles to it catching on worldwide.

"The real kick-start should be around 2012-2013," said telecom analyst Greger Johansson of Stockholm firm Redeye.

The roll-out of 4G networks - up to 10 times faster than today's high-speed third generation technology - is being slowed by the need for compatible hardware and massive investments. Another problem, analysts say, is timing.

The new technology is appearing on the scene as the world is still aching from the global financial crisis.

Operators remain far more wary of opening their wallets to the next big technological splash than they were when the last generation technology widely hit markets in 2003.

Also slowing the technological migration is the fact that operators have yet to develop a good method of cashing in on consumers accessing ultra-high-speed Internet networks through computers and phones.

TeliaSonera, the partly state-owned Swedish-Finnish firm behind the world's first commercial 4G network, estimated that out of almost 400,000 potential 4G consumers in downtown Stockholm and Oslo, just around a thousand have so far subscribed.

And for those consumers, 4G still means only an ultra-rapid computer Internet connection - allowing the almost instantaneous display of webpages, fast transfers of even the largest files, and swift video streaming.

"As for the (4G-compatible) phones, we say 'Forget it for now'," TeliaSonera's vice-president of mobility services Lars Klasson said.

"We're a small market and the phone makers are waiting for the big ones like the US or Japan" to launch widespread 4G networks before making compatible phones, he explained.
