Three has announced plans for a major upgrade to its UK mobile broadband infrastructure.
The firm, which invested millions in 2011 upgrading to HSPA+ technology, is aiming to further raise performance levels.
At present, HSPA+ currently runs on the 21Mb technical standard, meaning dongle users can take advantage of broadband speeds of approximately 10Mb.
But Three is to double this to the 42Mb standard, offering customers twice the broadband speed potential.
"Now, once again, we are going to move the game on and bring another first to the UK market," the broadband provider stated. "It's the leading-edge version of 3G technology."
Three is describing the technology as HSPA+ 4G, but has pointed out that this is different to long-term evolution broadband.
"Because the technology uses dual carrier equipment – meaning it can latch onto two signals at the same time and transmit and receive double the data – it will also improve capacity across the network," the firm stated.
"This will mean more consistent speeds especially in busy areas and at peak times of the day."
Three noted that the technology is already up and running as a test along a small part of the M3 corridor and south west London, and a nationwide rollout is expected to commence later this summer.
"As well as continuing the 42Mb roll out, we'll also be running our own LTE trial in the next few months to get ourselves prepared for this technology, when the spectrum needed to run it is made available," the broadband provider stated.
With Ofcom yet to run the required spectrum auction, the likelihood is that this leap is still more than a year away at the earliest.
"But in the meantime, we'll continue our ongoing network improvement programme to ensure that whatever it is you want to do via the mobile internet, we are the network to be on," he stated.
