Deustsche Telekom, the parent company of US mobile operator T-Mobile, is reportedly pursuing discussions with Clearwire to strike a deal that will allow it to use Clearwire's spectrum for its 4G service.

Bonn-based Deustsche Telekom has plans to compete with other US carriers' 4G efforts by spreading out its U. S. networks.

The deal will assist Clearwire also as Deustsche Telekom could provide it with funds to finish its initial bailout.

Moreover, earlier in August, Clearwire said it required $2 billion by the end of 2009 to expand its network.

AT&T Inc. and Verizon Wireless have already upgraded their network systems.

As per some other media reports, Deutsche Telekom is also in talks Sprint Nextel and MetroPCS Communications.

In the recent trading, shares in Clearwire soared to $8.97, gaining 2.1 per cent on the Nasdaq Stock Exchange, while shares in Deutsche Telekom increased by 0.3 per cent to 9.33 euros in Frankfurt.
