London Underground network receiving 4G connectivity by Three and EE

The era of modern technology is passing by, meaning upgrades we only saw in movies are the regular norm. Nevertheless, the underground transport systems have weaker network coverage which remains a concern as the upper ground is spectating some of the highest networking speeds. For upgrading the underground network to 4G connectivity, Three and EE are tasked to complete the network upgrade within 2024.

London underground system has been long waiting for a network upgrade as passengers and waiters in the area fail to receive good coverage. Three and EE will work together in the BAI Communications network. The interrupted ranges will support 4G connectivity between runnels and commuters across the web. It will give the whole journey uninterrupted 4G service.

On Tuesday, two of four mobile phone companies signed up to roll out the feature. Passengers of the Tube sent continuous complaints that they failed to receive sound signals for browsing or even make phone calls. The joint venture by Three and EE will bring the matter through until the matt4er closure with the networking upgrade.

Vodafone and O2’s decision is still pending to join the venture as they also have a large customer base in need of a networking upgrade. Chances are, if they don’t join, their customers will continuously fail to get coverage in the tunnels, which might turn into a loss of revenue.

Since March 2020, 4G has been an essential part of the networking infrastructure, providing a much-needed speed bump for powerful devices, which is compatible enough to consume tons of bandwidth.

4G network across London Underground is a big step but long due as many concerns raised on tackling the situation. But when two of the four mobile companies signed up to solve the issue, it suddenly seemed easier to implement and great news for tube transportation.

Streaming videos or calling in the tunnels is difficult as the ground layer is thick enough to cut signals of passenger’s devices. Vodafone and O2 may join the venture as there are millions of pounds to gain once the infrastructure is live.

According to Tfl updates on Tuesday, within June next year, the Crossrail will open, and the network upgrade will benefit passengers through the whole underground network.

Oxford Circus, Bank Euston, Tottenham and Camden Town will be connected within 2022 as the work is already in progress. By 2024, the complete infrastructure upgrade will be done, and even Crossrail will benefit from the 4G network.

Mayor Sadiq Khan said that he’s delighted to see ‘Three and EE sign up as the first operators to provide full high-speed 4G.’ the difference to the passengers will be huge as they need to stay connected below the ground similar to what they do above during the move. And their free time is killed during the no network situation, which can get frustrating quickly.

To ensure a flawless 5G network across the country, the tunnelling system needs 4G upgrades first. As it will ensure we have country wise fastest network access for everyone. Even the economic benefit from the upgrade will come in millions to the network providers.

Chief executive of Three, Robert Finnegan, said passengers "will be able to enjoy smooth streaming, phone calls underground and continued seamless coverage while they travel, even in tunnels."

Investing in the ever-growing economy of London is a no brainer to get the return in a short period. And as it’s a tech upgrade, the benefit will only impress users about the network companies. Along with financial gain, upgrade providers will be among the first to serve in underground network infrastructure, which is a remarkable achievement itself.

The long-term revenue stream looks promising, and if all four of the significant carriers work together, the experience it’ll be a seamless experience for all users.
