For both mobile workers and consumers accessing the mobile internet can be a nightmare: slow speeds, congested networks and a lack of available coverage all combine to make for a disappointing experience.

However, a growing number of projects are coming to the fore that could well end this situation by providing access to several wide-scale Wi-Fi deployments across London and beyond.

Firstly, Transport for London (TfL) confirmed it is on track to roll out Wi-Fi hotspots to 120 of its stations in time for the Olympic Games later this year, with its chosen supplier set to be announced in due course.

"London Underground is continuing with preparations to install the necessary infrastructure and is on schedule to complete the project as planned," said TfL's director of strategy and service development, Gareth Powell, in a widely reported statement.

"An announcement of the chosen service provider will be made in early spring, leaving plenty of time for this to be delivered to customers in time for the 2012 Games."

Secondly, O2 announced on Tuesday that it has signed a deal with restaurant chain owner Tragus to provide free Wi-Fi access to both customers and non-customers in 120 locations, including Cafe Rouge, as well as Strada and Bella Italia restaurants.

"This agreement takes us a step closer towards our vision of changing the public Wi-Fi landscape within three years, by offering people free Wi-Fi connections in the places they want it most," said the managing director of O2 Wi-Fi, Gavin Franks.

"As O2 Wi-Fi's footprint continues to grow, we hope that more people and businesses start to realise the potential of free and fast Wi-Fi."

The rollout comes after O2 announced earlier this month that it will be creating what it claims is the largest free Wi-Fi network in Europe across areas of Westminster, Kensington and Chelsea, also in time for the Olympics later this year.

The confluence of these projects, which will see smartphone and tablet users across London and the rest of the UK able to access a growing number of Wi-Fi hotspots, is a welcome development for the UK.

Hopefully, it will show visitors to these shores that our nation progressing nicely in the digital era.

The demand for high-speed internet access on the go shows no signs of abating, and Virgin Media has seen that it could capitalise on this market by offering a free Wi-Fi service in London.

Virgin Media chief executive Neil Berkett explained in an earnings call that a free Wi-Fi service is on the company's agenda as part of its work to innovate in the broadband market.

"We continue to run our pilots and trials, and we are in quite advanced conversations with some boroughs and councils in respect to completing a metro rollout in parts of the London area," he said.

"The proposition would be that we would provide free Wi-Fi access for all at 0.5Mbit/s with full access to Virgin Media customers up to 10Mbit/s, and we may consider speaking to mobile network operators about wholesaling that as an activity."

Berkett added that the "punt" is exciting given the demand for better mobile internet speeds. "I think it is a real opportunity if you think about consumers' needs for data outside the home," he said.

The revelation is interesting as it shows how broadband providers are boosting their offerings with better internet access on the go, much as O2 is doing with free Wi-Fi in its stores.

BT, which has held sway in the outdoor public Wi-Fi market through its paid-for Fon and Openzone products, will not doubt be watching with interest to see whether Virgin goes ahead with its plan as the two broadband giants prepare to clash again.

One thing is for certain: visitors to London for the 2012 Olympics will be hoping that the networks are up and running to provide internet access as they cruise the capital looking for information on where to eat, what to see and which tube lines are broken.
