MetroPCS

The merger of Bellevue-based T-Mobile USA and its smaller rival, MetroPCS, has won regulatory approval and will likely move forward. But one analyst says even the combined company may not be large enough to compete with the biggest wireless carriers.

For a mobile phone company, having the biggest, fastest network is what counts, especially as more and more people use smartphones to stream video or listen to Pandora.

Morningstar analyst Allan Nichols says MetroPCS will give T-Mobile a much-needed boost of wireless spectrum as well as faster technology.
