The FCC is probably concerned that such a device could become common enough that they would have trouble enforcing the rules at a later date: I'd bet they feel it's better to nip it in the bud. Don't forget that bureaucracies have very long memories: the FCC is, no doubt, harening back to the way the Citizens Band grew into a monster that they can't control even today. Bill Horne Moderator

Putting on my mobile carrier hat, I would say that there is no way to tell where someone might install one of these things, and it's clearly being marketed as a way to bypass the carriers' network, not as a signal booster. I'm not a big fan of any of the mobile carriers, but this does not impress me as a viable way to circumvent them. If the mobile carriers weren't such doofuses, they would give you a free real femtocell if you'd promise to keep service on your cell phone for some period, a year or two. R's, John

R's, John PS: A 20 second visit to magicjack.com would have answered this question much more quickly. ***** Moderator's Note ***** According to an article in the Winter 2009-2010 issue of "2600": "While the underlying carrier (YMAX) is a CLEC, MagickJack is specifically not offered as a CLEC product." The article says MagickJack claims to be a "multimedia experience which includes a voice over Internet information service feature. It is not a telecommunications service, and is subject to different regulatory treatment from telecommunications services". It's an open question as to why MagicJack's owners take such pains to try and distance their offering from FCC and local PUC regulation. Also, according to 2600, the MagickJack software cannot be uninstalled, even if a customer returns the MagickJack. The author also rates MagickJack's voice quality "between poor and terrible", and goes on to say that "In my market, MagicJack quality is so poor that the service is virtually unusable". He also notes that "... when you install the software, the End User License Agreement (EULA) has a few nasty surprises", which includes the right to send the customer commercial email messages, display ads on the computer, and supply computer-usage details to Google. Suffice to say, I'd be very careful about purchasing any MagickJack offering, whether a femtocell unit or otherwise. Bill Horne Moderator

Not really. My presumption was being able to receive a call made to my cell phone number. It appears call forwarding would have to be used to make that work, which in this circumstance, would be a giant PITA.

For example, I don't believe people who work in the cellphone divisions are unionized. I don't believe newcomer cellphone carriers or landline carriers, or cable phone are unionized either. Many functions for large businesses once performed by unionized telco personnel are now done by non-union employees of the subscribers. The union itself calls itself "CWA" now and for years has sought to represent service workers in other industries.

Sounds much like a clone of the Verizon femtocell unit (officially known as a "Verizon Wireless Network Extender") that people have been talking about elsewhere in the newsgroup. If Verizon can do it "legally" there is no reason someone else can not do the same thing provided they don't step on someone else's patents, but then again phone companies seem to hate competition from startup companies. Especially if the competitors product actually works. ***** Moderator's Note ***** The problem is that it's NOT the same thing as a Verizon femtocell: it is, as another reader pointed out, only a way to turn a cell phone into a cordless phone. The Verizon offering gives customers access to their regular cellphone features, such as voicemail, but the proposed MagicJack product does not. Bill Horne Moderator

Harold, TASI simply switches "circuits" when the call is idle in one direction or the other. There is a set of circuits that are available in each direction and the TASI terminal assigns each call to a circuit depending on whether voice is detected. The absence of voice makes the receiving terminal insert noise into the circuit to the customer so there is no need to transmit any signal. In this fashion, more than twice the number of circuits can be put on a multiplexed circuit. In the old analog days, a group was not 12 circuits on undersea cable, but 16 circuits (3 kHz bandwidth instead of 4 kHz) a few groups would be assembled into a set for TASI. The circuit gain was well above 100%. Digital TASI uses T1 carrier and typically has a circuit gain well above 100%. In the digital version, if a circuit needs connectivity (i.e. speech is present) and there is no available time slot, the link regresses to 7 bit encoding instead of 8 bit encoding to allow the conversation to continue. The controls for a TASI system are expensive, thus their use was restricted to expensive circuits, e.g. undersea cable. Today there is a real surplus of undersea fiber capacity, so these kinds of systems are not as attractive as in previous times. VOIP often uses the same kind of active circuit switching (albeit in the packet domain...) and doesn't send packets when there is no voice. BTW, voice detectors have an "attack time", so often the first part of a syllable is clipped, reducing the quality of the connection. Modems on TASI circuits resulted in a dedicated circuit, since modems had no quiet time. ET --- news://freenews.netfront.net/ - complaints: news@netfront.net ---

They still have not done a replacement, just a bunch of fixes. The PUC is getting weekly updates from both AT&T and me. My DSL took a dump again and I switched over to my Sprint MiFi and plan on having them adjust my bills for the past 6 months by 1000%. I was up in the mountains north of Sacramento and it looks like they are about 3 months from U-verse there, that will be nice since all they have is dialup unless you want to spend $200.00 plus $60 a month. -- The only good spammer is a dead one!!

When they receive an incoming LD phone call, they bill the LD carrier the usual switched-access termination fee. When they place a call, they take advantage of a regulatory ambiguity which states that VoIP-originated calls might be exempt from paying.

The 100 mW rule is more urban legend than fact. The 100 mW power limit for *intentional* radiators applies (or did apply) to the AM broadcast band and 27 MHz CB. Other bands that allow unlicensed intentional radiators have different power levels, often based on field strength. The current rule for AM broadcast is a field strength of 15 uV/m at lambda/2pi from the radiator (this is used for carrier current), though campus systems are only limited in strength at the edge of the campus. CB is now 10 millivolts/meter at 3 meters. For FM, 250 microvolts/meter at 3 meters. For 216-960 MHz (old cellular), 200 uV/m at 3m. >On the other hand, the article neglects to mention that this device in >effect turns your cell phone into an expensive outgoing only cordless >phone.

Indeed, it's not clear to me that unlicensed intentional radiators are really allowed on occupied cellular frequencies.

Absolutely -- most telco voice transmissions today operate over a packet-switched network, albeit with very small packets. With the current state-of-the-art in high-speed network technologies (all packet-based), the serialization delays that motivated the design of so-called "cell-switched" networks like ATM -- the backbone of most traditional telco networks -- are much smaller. An appropriate queueing discipline combined with some sort of resource reservation in the switches can provide sufficient quality-of-service for high-definition video circuits, never mind the comparatively miniscule bandwidth required by voice telephony. Consider, for the moment, the case of someone using VoIP to make a local call over naked DSL. Their VoIP terminal (i.e., phone) will send RTP/UDP/IP packets over the home Ethernet LAN to the DSL modem. The DSL modem then encapsulates these packets in ATM cells and sends them to a DSLAM in a telephone central office. Those cells are then forwarded by the DSLAM over permanent virtual circuits on a carrier ATM network (possibly even the ILEC's network) to the ISP's POP -- probably located in or next to another CO in a nearby major city -- where a router (probably made by Cisco) accepts the ATM cells and reassembles them into IP packets, delivering them to the VoIP gateway (possibly in the same Cisco box) which extracts the digitized audio,[1] possibly transcodes it, and probably converts it back into ATM cells again (this time labeled "voice" rather than "data") for carriage on the ILEC network to the terminating CO switch. The only reason for the ISP to use ATM between the DSLAM and their POP is the fact that ATM is readily available in nearly every ILEC CO in their service area, whereas dark fiber isn't. -GAWollman [1] The RTP protocol allows it to accurately reconstruct a continuous audio stream from the UDP/IP packets it receives. -- Garrett A.
