Vodafone UK has began the roll-out of a LTE Advanced technology to boost existing 4G mobile service using Carrier Aggregation. Vodafone is rolling out the enhanced technology from this month in Birmingham, Manchester and London and to other UK cities during the rest of this year and 2015.

Carrier Aggregation is particularly well suited to Vodafone’s 800MHz and 2.6GHz spectrum, which the company secured in last year’s auction. Low frequency 800MHz spectrum travels further and penetrates better through walls to provide the best network coverage. 2.6GHz is ideally suited to smaller geographical areas of high population density.

The rollout of carrier aggregation is part of £1 billion Vodafone is spending on its network and services across the UK this year. It follows the nationwide provision of HD (High Definition) Voice technology and the Vodafone Rural Open Sure Signal programme aimed at giving remote communities 3G coverage for the first time. 

Additionally, Vodafone customers on 4G price plans with 4G compatible smartphones and tablets will be able to ger 4G roaming in 23 destinations worldwide as 19 new destinations join Greece, Italy, Spain and Portugal which launched earlier this year.
