Femtocells: your very own home cell network

Besides the “femtocell” sounding like a robotic sex toy or an individually wrapped feminine hygiene product, in technological terms it is a router-like device which converts a portion of your broadband bandwidth to provide you with a compact cell network in your house.

The concept is a relatively simple one. You buy a femtocell from your mobile network operator, because if you were on Verizon and bought a T-Mobile one, that would be pretty pointless. You switch it on, plug it into your broadband router, and as simple as that, you have cell signal.

In the recently built postgraduate college on the University of Kent’s Canterbury campus, students were left without phone signal due to the lack of cell transmitters in the area and a building which was designed, almost to withstand the blast of a nuclear explosion.

For many living in hilly areas, especially but not exclusively in England, will find that cell signal can be patchy from room to room.

Another use for femtocells would be trains and railways. Not only do phone users struggle to maintain a phone call travelling at 130mph through the countryside, but the constant barrage of tunnels makes it difficult to maintain a connection. As many trains now have wireless Internet access for mostly business users, adding a femtocell to the center of the train would ensure a constantly connected phone-to-cell network.

Some large network operators are already supporting femtocells and offering them to consumers. But the problem lies when multiple family members use different phone operators.

As broadband routers often provide a home network of speeds around 2-4MB speeds, the increasing number of devices connected to routers are slowing the overall network down. Femtocells often have QoS (quality-of-service) which allows a dedicated stream of bandwidth to the device. So even if you’ve got someone on the Xbox, somebody else streaming from YouTube, and a number of torrents downloading, you are ensured a good quality connection when using your phone through the femtocell.

Are femtocells an emerging technology you would like to jump on the bandwagon of, or another catchy gimick which won’t make its way past Christmas?

Good resource and informed in an understandable way. I am new to this technology and now understood how it is working, just with a connector we could do wonders.

Realy?
jdbukis@... 17th May 2009
Well Orange (The comapny) I work for have been offering this technology in one form or another for over a year now.
We offer (pico-cells)femtocells to our buisness customers and our home users are offered a technology called UMA (our unlicened mobile access)which means they can connect there phone to a router and make voice calls on our network through the router.
Its not massivly popular but it has its use, its certainly not stupid as its a dam sight cheaper to pay for these and make calls mobile to mobile than from landline to mobile.

I personally use a Femtocell here due to poor signal from my carrier at home. They do work as advertised with some limitations. The biggest drawback is the lack of support for EVDO speeds. This coupled in with the fact that the device will only support 3 phones using it at a single point in time are the big drawbacks. If one has poor coverage,they will remedy ones inability to make cell calls.
This is tempting for me, as, living in a hillside area of Los Angeles, we have never gotten adequate cell phone coverage. Even though we are a scant 20 minutes from the center of Downtown. I could maybe get adequate cell coverage by getting a femtocell, but by doing this then I have basically paid for the network - cell and internet line - the cell company has to maintain nothing. Say I make a call from my cell phone to a landline or the customer of another cell company. The chain of comm is cell phone - femtocell - internet - some other company network. My cell company doesn't carry the call at any stage - yet I'm paying them for the service. Nice work for them. The worst part is, the femto cell is tied to the wireless signal of my cell company, and so is one more thing that locks me into their service. Extra nice work for them!

I might be more interested if femto cells were universal and worked with any wireless signal, or could make use of agnostic VOIP or Skype at the user's choice. THAT would be compelling. It would also be appropriate if I weren't charged any minutes whatsoever for using the femto, since, as I say, I'm not actually using the wireless network at all.

imagine that....
Christian_<>< 17th May 2009
This way they can wash their hands of it, wireless technology is still yet in its infancy it is not a reliable 99.99% uptime service as a land line no matter what they say.

The big problem right now is, they are NOT investing money in the infrastructure, MCI was running fiber all over creation however they got caught up in the (doc com) blowout and went belly up.

At&t Verizon are too worried about stock prices to care about building a world class infrastructure.

It would be nice if companies advanced technology and infrastructure instead of worrying about stock price earnings......

Maybe true in this case
jdbukis@... 17th May 2009
However the UMA service used in the UK does have a backbone that is paid for by the network provider as the voip service it routes too is company owned.
And in our case the end user only needs to own a router, it does however charge voice and data to the mobile tariff.
The voice charging seems to be fine to me however the data chargin the mobile tariff seems to be a bit much. It does seem to work on wifi if you turn of the mobile connection (Only tested this on a blackberry so i dont know about other handsets).

Tax breaks for the mega corps
Christian_<>< 17th May 2009
Tax breaks need to be given to the big mega corps to lay fiber to home and other infrastructure changes that NEED to happen.

Instead, they do a little here/there and then bill the living daylights out of you.

Living in a rural area we have laid a lot of fiber and trying to cut out the middle man.


My Kingdom for infrastructure!

The UMA system we use shares the same limitations it sounds, however our pico cells do not however it does require installtion by a technition and can only be used in buisness estates and simiar places.

Well i understand that but you would need to ensure they spent the saved money, otherwise they would likely just pocket the money.

Would be a great temporary fix
ejhonda 18th May 2009
For those who live in remote areas (my parents are in the Endless Mountains area of PA) and have other issues to deal with (aluminum siding), this would rectify situations where they have to stand still in front of the bay window in order to make a call.

They had broadband at least a year before I could get it in my urban area, but their cell service is weak. This would be a great workaround until service catches up.

Oh thats REALLY clever.

Another microwave transmitter.

We spend all our energies as parents on blocking these damn radioactive devices from being built near our homes because we dont want to be bathed in radiation, but just because someone might not make as much money today and (perish the thought) they werent irritating everyone around them doing so, some smart arse designs one for their very own home, public transport, cafe and everywhere flaming else.

Fine, if it keeps these morons who have to live with a transceiver clamped to their head from walking down the road shouting, we can then also get rid of the big uplinks, and only have them where they are really needed - safe, where people arent.

Dont get me wrong, mobile is good. But at what cost?
This is just another way to make money by the looks, because it could be so much better.

so far, the only way get out of your contract
with the cell phone company has been to tell
them (some variation of) i work out of my home
now and i can't get ANY cell reception here..
please cancel my acct so i can try w/ another
carrier

and your carrier would have no other choice

the cell ph company does NOT want to lose your
business - they'll bend over BACKWARDS to keep
you

what they *ought* to be doing is putting these
"femto"thingies in ppls houses (at no charge)
that are threatening to leave due to poor
reception

Customer service
Guybert 18th May 2009
I make it a habit to change my cell carrier at the end of a contract. None of them have ever 'bent over backwards' to keep me, and 2 of them never even asked me why I was leaving. No, they don't care if you leave, and until they start caring, I'll keep switching!

So, I pay to buy a femtocell, and I pay airtime to use it, and I pay for the internet access it uses? Why would I want to do that when I can use much cheaper VOIP systems? If my mobile does not work well at home, why not have it forward calls to skype, that I can also use on my mobile via wifi? Or use google voice and have it ring to my skype # or land line? Again I ask you, why is it a good deal to pay for the hardware, pay for airtime and pay for the bandwidth for a femtocell?

it gets worse on payments
dedrizen 18th May 2009
I looked at getting something for my home not too long ago and skipped it. Here's how it goes.

Pay for femtocell device. Pay for cell phone service. Pay for internet service. And #4, a monthly fee to connect the femtocell device to the carrier's network.

This was where I backed off the prospect. The cost for the device I was looking at was about the same as your home router/modem and offered by my cell phone provider at the time. It was the monthly fee that turned me off. They will pay for the use of those big towers some of us don't like but I would have to pay an additional monthly fee when I provided everything for them?

I don't make a fortune and do not have room in my monthly budget to justify it. We don't even get cable, just the high speed internet because I work on computers--and my wife has become spoiled because she also sees the speed benefits on her smaller downloads/uploads--I am the one who downloads security patches, iso files, and assorted similar downloads. I just live with the fact that if I want to take calls I need to avoid the "dead" spots in our residence, which just takes some miniscule planning on my part.
