MagicJack Femtocell Gates Cell Traffic to VoIP 243
olsmeister writes "MagicJack is demonstrating a femtocell device at CES that will allow any GSM phone (locked or unlocked) to place free phone calls over the internet using VOIP. The device costs $40 and includes free service for 1 year. It supposedly will cover a 3,000 sq ft house."
Is this legal? (Score:5, Informative)
There's no "trick" to work with locked phones. GSM has no network-side authentication, so all you have to do is impersonate your carrier's network (this is trivial). But I can't imagine this being in line with regulations. Another issue is that encryption does not work unless you're a carrier and share a secret with the phone's SIM, which means that invariably your calls will be broadcast in the clear when you're using this device.
I'm not entirely sure this is a good idea. Femtocells are great, but impersonating carriers gets you into all sorts of sticky issues.

I have one.
The software/drivers are in no way reliable enough to make it a serious replacement for a "real" phone, but as a backup when you want to make free calls around North America, it's not a bad solution. The call quality is perfectly fine. It's worth the $20/year they charge, but not a whole lot more. If they could get their software (and their abominable, laughable, seizure-inducing support) to work a little more smoothly, I'd be more willing to consider additional products from the company.

Requires PC (Score:4, Informative)
The current MagicJack is a device about the size of a matchbox with a USB connection and a phone jack. The USB connector plugs into the user's computer, loads software onto it, and uses the computer's power, processor and broadband connection. The femtocell will also use the PC, but it will let users make calls with their cell phones instead of wired phones.
Why can't they make a standalone device!?
seems decent (Score:3, Informative)
Some interference occurred when the tester tried talking while downloading a large file or playing an online game. If you can live with that, we think the Magic Jack is a great deal.
Something that could easily be overcome with a router that has decent QoS capabilities. Overall, it seems like a decent deal.

Not to mention that UMTS phones will prefer the UMTS signal even if a GSM signal is available. Also, it will stop working once GSM goes away and is fully replaced by UMTS (which does authenticate the network), if that does ever happen.

Why femto? (Score:4, Informative)
Why is this called a femto cell? The area covered is much more than 10^-15 of that of a standard cell tower. If this device covers a radius of 50 ft, and a tower works to a radius of about mile, then the fractional area covered is 10^-4, or somewhere between a microcell and a millicell.

The names are not meant in the traditional mathematical sense; they just refer to coverage. A microcell will cover roughly a hotel, a picocell a typical office floor.

Is it really that much better and more convenient than WiFi? When I am in my house, I press the Internet calling icon on my phone and it connects to my VoIP provider's server via SIP.
For starters it will work for ANY GSM phone. It doesn't matter if it has WiFi or not. Second, it's cheaper than your VOIP provider unless your VOIP provider can beat $1.70 mo.
I have been using T-Mobile's @Home service for the past year ($10 month as a third line) and it's been extremely reliable. I didn't like Magic Jack because I needed a computer and their software on it to have phone service at home. If this thing works as advertised I just may pull the trigger.

$20/year really isn't possible, because no matter how low their internal operating costs, they have to terminate calls on the PSTN, and they don't have equipment in every city to do that on their own network. Legally mandated termination fees for rural areas can be $0.04/minute (or sometimes even higher) -- at that rate you'd only be able to talk for 500 minutes before they'd be in debt.
My guess they're taking advantage of these same fees, and giving everyone inbound phone numbers in high-termination-fee locations. So they collect $0.04/minute every time someone calls you, but for most outbound calls they only pay the much lower termination fees for metropolitan areas. It's the same sort of scam we've seen from companies offering free teleconferencing, or free international calling. It's probably not illegal under current laws, but it's also not the sort of thing that's sustainable long-term, because real phone companies aren't going to put up with paying for MagicJack's phone service.

Not quite.
The device is $150. IF you sign up for an unlimited minutes plan, they will give you a $100 mail-in rebate. The plan's pricing depends on which test market you are in, and whether or not you have AT&T DSL or U-Verse service. But in any event, an unlimited minutes plan is optional. You can just buy the box for $150 and use your plans minutes as normal. The purpose the box serves under those circumstances is merely improving your coverage.

Houses with builtin Faraday cages (Score:5, Informative)
One of the weird things I've run into in doing 3rd-party tech support is that houses can, indeed, have Faraday cages.
If the house is of the right vintage (mostly pre-1950's) it may have plaster walls. One method of hanging plaster is to put up a metal mesh lath [wikipedia.org] which can make a very effective Faraday cage out of each of the rooms.
A modern variation on the builtin Faraday cage is rigid foam insulation that is covered on one or both sides with a metal reflective coating, often used in external wall insulation.
When a new customer calls and says they are having trouble getting wireless to work in their house, one of my first questions is does it have plaster walls.

Pretty sure femto refers to the radius in light years. At least, that's how I would defend it, if I had to.
