Millions of mobile phone owners pampered for years by numerous Nokia model handsets could soon expect the release of new smartphones from the Finnish firm powered by Microsoft's mobile platform, reports said.

This time around, Nokia declared that it has resolved its past mistakes, which proved too costly for the giant phone manufacturer that for more than 15 years dominated the global mobile phone market with its strings of handsets that cater to all types of consumers.

Acknowledging that Apple and Google successfully chipped away significant market shares from its traditional bastion, Nokia initiated measures that practically put the company on the offensive, which was highlighted by its high-profile alliance with Microsoft.

When Nokia CEO Stephen Elop formally announced the partnership with the giant software maker on February this year, the company also signalled the inevitable demise of its in-house mobile operating system, the Symbian OS.

Tech watchers are strongly anticipating the onrush of new Nokia handsets by the last quarter of 2011 and many are not discounting the possibility that an official unveiling will be witnessed by Wednesday this week, which is the appointed day for the Nokia World Conference to be staged in London.

Company releases have been hinting that new Nokia handsets will be unleashed by the final months of the current year and consumers could expect fresh devices with the Windows mobile OS deployed with the hardware.

Nokia has also indicated that it has forged a deal with Qualcomm that will allow the latter to supply the processor for the former's initial batch of Windows-based smartphones, and possibly the succeeding ones that Nokia will roll out in the quarters ahead.

Jo Harlow, Nokia's executive vice president of smart devices, told The Australian that the company had implemented critical both corporate and manufacturing adjustments to ensure that Nokia handsets will hit the market by the last quarter of 2011.

"Our focus has been on getting to market, as opposed to lots of differentiation," Harlow said while adding that shaving off features from phones set for release this year significantly boosted Nokia's aim of issuing Windows phone by the end of the year.

Traditionally, the last quarter marks the period of gigantic sales leap for most consumer electronic makers, with Apple and Samsung leading the way thanks much to their lead time in providing products that already won the loyalty of millions across the globe.

Nokia has expressed optimism that it will not only offer sufficient competition to current market leaders but the company will also reclaim its former glory owing to the perceived dominance that Microsoft achieved in the PC market, a reality that Nokia hopes will be extended to its new thrust.

While Harlow has remained mum on the exact specifics of new Nokia models that will be sold in the months ahead, she stressed that Windows has largely erased much of the complaints about the company's earlier offerings.

Also, Nokia made sure that its coverage will reach more consumer hands than ever before as the company revealed upcoming product lines that are expected to please every market segments, and that includes designing more 'world phones' that work both on GSM and CDMA networks.
