The maximum in-band power limit for 3G mobile spectrum licences is to be increased, following approval from the communications regulator.

Ofcom has agreed that the present cap of 62dBm per carrier can be extended to 65dBm, a move which could enable greater availability of mobile broadband services.

According to ISPreview.co.uk, each of the five main mobile internet service providers had requested the change, which will affect the Frequency Division Duplex part of the 3G spectrum.

Vodafone, O2, T-Mobile, Orange and 3 were all seeking a higher power limit to support their supply of voice and data services in the UK.

Last month, the Global Mobile Suppliers Association reported that mobile broadband services based upon long-term evolution technology are gaining in popularity.

The organisation revealed that more than 100 LTE networks are currently in progress or planned in 41 countries, up by 71 per cent on figures compiled six months ago.
