(Telecompaper) Vodafone plans to boost investment in its UK network by more than 50 percent to almost GBP 1 billion in 2013, reports the Financial Times. The increased capital expenditure comes as the operator prepares for the launch of 4G mobile services and integrates the fixed-line network acquired through the takeover Cable & Wireless Worldwide. One source familiar with the situation said that C&W Worldwide had suffered from underinvestment, leaving Vodafone needing to improve the networks, as well as integrate them with the existing business. Vodafone is expected to announce an increase in UK capex of more than GBP 300 million for 2013, up from GBP 600 million in 2012.
