Nokia Siemens Networks has announced a new focus on end-to-end mobile network infrastructure and services, with a particular emphasis on mobile broadband.

It says business areas that aren’t consistent with the new strategy “are planned to be divested or managed for value”.

A new poll of over 1,500 people by UK comparison website Broadband Genie has found that most users are unhappy with the speed of their mobile broadband connection. In fact, just 5.3% of users said they were definitely happy with their mobile broadband speed.

A further 15.8% described it as OK, while 56.8% said they were unhappy.

The USB ‘dongle’ is still the most popular form factor for mobile broadband modems, according to a new report from ABI Research.

It estimates that 110 million USB units will ship worldwide this year, contributing to a total of 150 million mobile broadband modems that are expected to be shipped worldwide in 2011. That’s 46% growth year-on-year.

Analyst firm Berg Insight says HSPA and LTE mobile technology accounted for 20.6% of the total number of broadband connections on PCs and tablets in Europe at the end of 2010.

The number of mobile broadband subscribers grew by 33% year-on-year in 2010 to 33.9 million and is expected to keep growing to 96 million by 2016. In North America the figures were lower, with mobile broadband accounting for just 13.2% of the total number of connections.

A new report from Juniper Research says mobile network operators urgently need to spend billions of dollars increasing capacity and optimising their backhaul networks to meet the demands of mobile broadband users.

The report calculates that operators need to spend almost $840 billion (£530 billion) globally over the next five years.
