This financial institution vacation weekend is likely one of the final large dates within the UK summer time pageant calendar, with Studying and Leeds, All Factors East and Creamfields North anticipated to attract big crowds.
With massive attendance numbers at festivals come overloaded cell phone networks, leading to pals shedding contact with each other and fogeys being unable to contact their youngsters on their first large weekend away at Studying and Leeds, lengthy a bacchanalian ceremony of passage for post-results GCSE and A-level college students.
These breakdowns in communication have turn out to be as a lot a fixture of UK festivals as fried halloumi and customized flags. Why, in an age of 4G and, more and more, 5G, is that this nonetheless taking place?
“The reason being merely mobile capability,” says Izzat Darwazeh, a professor of communications engineering at UCL. “Persons are demanding extra of their telephones now and need these items to be speedy. So the demand on bandwidth or capability turns into a lot increased.”
Networks work on a collection of cells over a particular space, and every cell works on a unique frequency to neighbouring cells: think about a honeycomb of self-contained pods. If there are too many telephones in a cell, it will get overloaded. “The capability per cell is proscribed,” says Darwazeh. “You possibly can double or triple the capability, however you’ll be able to’t enhance it a thousand instances.” And since our bodies take in cell alerts, your telephone connection turns into exponentially weaker the extra individuals you might be round, Darwazeh explains.
To treatment the difficulty, additional masts will be quickly positioned the place there’s biggest demand. Alex Jackman, a community communications at BT Group, says: “At someplace like Glastonbury, you might be speaking about dozens of levels, so that you prioritise the important thing areas the place individuals want sign. Every deployment that goes into the festivals is bespoke, based mostly on the place that protection is required.”
Glastonbury is likely one of the few main festivals with an “official connectivity companion” (beforehand EE, now Vodafone), whereas smaller unbiased festivals could also be ideologically in opposition to such cosying as much as a giant cell community. Native residents could oppose the set up of 5G masts.
Paul Kells, the director of community, technique and engineering at Virgin Media O2, says COW (cells on wheels) are among the many finest technological solutions right here. “They’re cell cell towers that may be transported on vans or trailers to supply short-term or enhanced cell protection in particular places,” he says. “These are efficient as they’re designed for fast setup and takedown.”
Given the fee implications, cell networks will rigorously select the occasions to which they bring about such options. Darwazeh says: “Slightly little bit of funding from these organisers can assure that there’s good protection, however I don’t suppose there’s a lot incentive for the cell operators to do that.”
Topography and never being within the sightline of everlasting masts, for instance at a pageant website surrounded by mountains, may severely restrict service.
Polly Barker, the pinnacle of manufacturing at Finish of the Highway in rural Dorset, says the pageant prioritises bodily noticeboards with up-to-date info as organisers are conscious that desperately oversubscribed networks imply social media posts are an inefficient communication instrument. “It’s exhausting to present individuals helpful updates concerning the pageant so now we have good assembly factors,” she says. “We all the time advise individuals to decide on assembly factors if they’ll’t communicate to one another on their telephones.”
The collection of one-day occasions that happen within the capital over the summer time – BST in Hyde Park, All Factors East in Victoria Park and Wi-fi at Finsbury Park – are tormented by their very own particular points, whereas Wembley has no drawback coping with crowds of 80,000 as a result of it makes use of a DAS (distributed antenna system) operated by the BT-owned EE.
“It’s infrastructure constructed inside and across the stadium and you’ll give capability to different networks to make use of,” says Jackman. “Whereas Hyde Park is served by three or 4 everlasting websites which can be on high of the buildings that encompass it. The everlasting websites aren’t constructed to deal with the extra 50,000 people who flip up at BST reveals on just a few nights of the 12 months.”

Whereas pageant employees and crew at weekend and one-day occasions usually have entry to wifi hotspots, making these out there throughout a pageant website is uneconomical and impractical. “Deploying many wifi antennas in a reside construct atmosphere is sophisticated as there are such a lot of different actions happening, from vendor setups, fencing and levels being constructed,” says Kells. “The broader the wifi protection, the extra complicated the construct plan.”
Darwazeh says that as 5G turns into extra broadly adopted, the densification of cells – ie extra particular person cells in an space coated by one community – means they may be capable of deal with extra individuals and telephones, and the pressure on the community will turn out to be much less pronounced. “A cell may need solely 30 individuals, so the capability can turn out to be very excessive,” he says. “The holy grail in cell know-how is to have one cell per person. However we’re 30 years away from this.”
When 6G rolls out in 2030, a lot of at this time’s issues will evaporate. However person behaviour will transfer in lockstep, with extra data-heavy content material in larger decision being shared or uploaded to social platforms. Know-how will nonetheless be enjoying catchup.
Barker suggests extra individuals ought to change off for a pageant, and viewers surveys by Finish of the Highway discovered that attenders didn’t need wifi hotspots and extra masts. “Would you like your viewers to hook up with the skin world?” she asks. “Is it really nicer that they’re within the subject and never bothered by receiving emails?”
For now, these going to festivals must make peace with the truth that cell reception will likely be as a lot a fitful dividend as sunny climate.
