London Needs 70,000 Cells For 4G

judgecorp writes "How many cells does it take to cover a city? In London's case, it will take 70,000 cells by 2015 for the next-generation LTE network needed for 4G mobile broadband, according to a calculation from PicoChip. A shame that's too late for 2012, when Mayor Boris Johnson warns that mobile data demands during the Olympics may overload the current 3G network"

    FTA: "Femtocell maker Picochip says London needs large numbers of micro cell towers by 2015" and "Dr Pulley’s report also stated that there needs to be in excess of ten million small cells worldwide by end of 2015". Now why would a maker of small cells say that?

      The current fastest home broadband on copper is 24Mb/s - and cable runs at 50Mb/s ... LTE will give 100Mb/s on the move and more if stationary ...why exactly do we need this and who is paying ?

      I've heard something similar from elsewhere - the thing that isn't very widely known about 4G is it requires at least ten times the number of cells in order to work. Which means the likelihood of seeing a rollout beyond the biggest cities is slim initially, to say the least.

      It bears a mention for our American cousins that London is part of the UK rather than London *being* the UK. The UK mainland is actually made up of 3 countries. Before your minds melt at the thought of fitting 3 countries into London, I refer you back to my first sentence.

      In the UK we whine and bitch about travelling 5 miles to work or travelling 200 miles for a holiday (vacation). It sounds pathetic but there are very few straight roads (the remaining ones were largely built by the Romans) so forward progress is slow.

      However, lots of people will make the effort to travel to London for the Olympics. It is a once in a lifetime opportunity for most people. Over 2 million spectators lined the streets of London to watch the wedding of Prince Charles and Lady Diana so it is most likely that there will be tourists from near and far milling about London during the Olympics sucking up bandwidth and generally getting in the way.

      Because in London a lot of buildings don't have direct fibre. There is the odd spot, but the majority simply don't. Most people are connected via ADSL, syncing at the maximum possible speed (the average is something like 6mbit on an "up-to" 24mbit ADSL2+ connection) so there is no left over bandwidth.
      However, BT do offer a service whereby their own home routers create a separate wireless network in which they allow other BT customers to use when they're not at home, so the idea isn't completely lost.

      Contrary to the nay-sayers who've already replied to you, BT already offer this service (BT FON) through residential connections, but only to other BT customers, and Virgin are rolling out a similar service (but with an access point in their box in the street). Some mobile phone companies offer free subscriptions to various WiFi networks (generally in pubs/restaurants) to reduce load on their 3G cells. One company offers 3G femtocells which use a home broadband connection, I don't recall any details.

      Also, I'd be surprised if many buildings in "downtown" (central) London don't have direct fibre. It's certainly available. There are thousands of financial companies, tech companies, etc, and a quick Google search shows many companies offering fibre to businesses.

      (10 years ago I went to school in the centre of a much smaller British city. Two telecoms companies regularly "borrowed" the playground and covered it in fibre, presumably before sticking it in pipes underground.)

    Sure - there'll always be a mix of small and large cells. But most of London is "high density areas". And it can be very difficult/expensive to find good sites to put full sized cell towers. If you can put many smaller cells inside buildings etc, just like WiFi stations, then it'll probably save the carriers a lot of money.

    The UK equivalent to Greater New York would either be "London and the Home Counties" or "The Thames Valley" (more likely the former), not "Greater London". Greater London is used for disambiguation from the "City of London" which is just over one square mile and is the financial district of Greater London. The City of London is to Greater London as Wall Street is to New York City. It's a (typically British?) quirk that we have to call what everybody thinks of as the city of London by another name because we're already using the term "the City of London" for something else.

Not the first devices, of course, but if you have a bunch of mesh networking devices running around carrying IP traffic on some other network the logical thing to do is to eliminate the other layer and run an IP network. This is the same reason for the unnecessary resistance to IPv6 (as opposed to the necessary resistance from the incompetent.)

Given that all of the national carriers tend to cover many major cities, it seems unlikely that London would need 70,000 cell sites for 4G.

    This is an article from the point of view of a company that sells small cell sites. Putting 70,000 cells in London would mean putting 115.3 cells in every sq mi. That's one cell every 5.5 acres.

    In Kansas City (US), I am one of the few people who actually get 4G at home with Sprint. If I'm in a moving car and I need to use the internet, I just turn off the 4G and use 3G because that's the only way to avoid apps saying "data connection lost". So I don't know if we need 70,000 cell towers but I do think what we have now is inadequate.

    Oddly enough, Sprint still seems to be the best option because dropping down to 3G is better than being cut off altogether by a bandwidth cap. And keep in mind, this is the United States so when I do bandwidth tests on 4G, I'm getting around 1.9 megabits/second. As soon as I read somebody saying LTE is faster than home broadband, I knew that person was in another country.
