    This is just exactly what I've been looking for. I just have to wonder if the sort of power output this thing needs is entirely legal. Oh well, who cares until the FCC shows up. According to this page [goodbyelongdistance.com] though, the range is 130km (80 miles) at sea level! Who needs a cell phone anymore unless you're going waaaay out of town. I suspect that's a typo though.

    It's not so much that I don't want a cell phone, it's more that I don't see any use paying $40-50 a month for something I don't use more than 100 minutes a month. Even if I only got five miles of range out of it, it would easily cover 99% of my needs.

He immediately chastised me for importing such contraband into the country and continually tsked tsked me while he checked the frequency on the equipment and salivated over it all wishing he had a set of his own. Well, here's the bad news....the frequency range is indeed 450 transmit from the base and 230 from the handset, reverse for the receive frequencies. This of course puts this outside the GMRS band and in the case of the 230 mhz band into some part of the aircraft communication band of frequencies. I do not have the exact frequencies in front of me at this moment but I have been for warned that by using these new toys of mine I would be infringing upon part of the Private Radio Service in the 450mhz range and, as mentioned, part of the aircraft comm band in the 230mhz range.

          It operates in a licensed part of the RF spectrum; if operate this in that portion of the spectrum without a license, the FCC can and has fined people $10,000.00.

          Released: February 26, 2004
          By the District Director, Philadelphia Office, Enforcement Bureau:

          I. INTRODUCTION
          1. In this Notice of Apparent Liability for Forfeiture ("NAL"), we find that Best Wok has apparently violated Section 301 of the Communications Act of 1934, as amended (the "Act").[1] The violation occurred because Best Wok operated radio transmitting equipment on the frequency 145.8376 MHz without a license issued by the FCC. We conclude that Best Wok is apparently liable for a forfeiture in the amount of ten thousand dollars ($10,000). ...

          At 11:30 a.m. on February 28, 2003, the agent entered Best Wok and inspected the radio transmitting equipment in the presence of the restaurant manager, Sae C. Hauwo. The agent found that Best Wok was operating a long-distance cordless telephone system. The system was comprised of a base unit that was located under the counter of the restaurant and a mobile unit that was in Hauwo's vehicle. There were no identifying markings on the mobile unit, but the base unit was marked with the Model Number GSM WLT-988. The FCC agent used frequency-measuring equipment to determine that the base unit actually operated on the frequency 145.8376 MHz and not the frequency 145.835 MHz as specified in the complaints. Hauwo stated that he installed the long-range cordless telephone system so that his employees could answer customers' telephone calls while making deliveries in their vehicles. Hauwo stated that he purchased the long-range cordless telephone system in another country and brought it into the United States to operate at the restaurant.

          You need to be very careful when purchasing RF equipment outside the US; that it's legal inside the US. A mistake can be expensive!

      I've joked about building something like this with friends before (probably using 2.4ghz cordless phones and external antennas meant for Wi-Fi) but they actually released a product?

      If the security is up to par (I'm thinking FHSS and maybe encryption) screw the cell phone! Why should I pay for both the cell phone and the landline? Ditching the landline isn't an option anymore because I need it for ADSL.

      With Verizon's freedom packages the landline is cheaper anyway (at least with the way I use the phone). And think of the possibilities if you attached it to a VoIP box....

      • With Speakeasy, you don't need the landline for DSL anymore.
        • No, but you essentially pay for it anyways for higher cost of their no-phone-line service. At least in my area.

          Its $18 for SBC Phone line, and another $12 for the oneline stuff, so why NOT have a regular phone service?

          Ill pay $4/mo for 911 and pizza delivery. Plus, it gives me a number to give out to pesky people like the landlord.
          • Thats what I get for posting directly and not previewing. I meant $6.
          • I get all that with my cell phone, because I have E911 service, and my local pizza delivery place doesn't go by the address they pull from the whitepages when they bring up my phone number. They always ask what address I want the pizza delivered to.

            I'd still rather have Comcast for internet access than have anything to do with the phone lines, however.
        • Depending on the residence, Verizon may be the only ones authorized to offer DSL.
          • Local telcos were, iirc, shoehorned into allowing other providers access to their network to provide local phone service and xDSL. It's been about five years since I've worked in the industry, so I could be wrong.
            • My friends live in a new apartment building and there is some agreement between the building owners and Verizon which allows Verizon to be the only provider of such services for 5 years.

      No doubt this could be converted. HAM radio amateurs use something comparable which is called 'packet radio'. The most common rate (afaik) is 9k6, which is referred to as 'fast packet'. Probably you can do better (using your own modulation scheme), but not very much (assuming the link quality is comparable to normal telephone).

      Something that I find surprising in some slashdotters is the fascination for wireless technology. Charming as it is, wireless is just another type of technology having its own benefits and hurdles. In general it is not the 'being wireless' part that is difficult: transmitters have existed for over 100 years.
      I understand other people's fascination, but anyone can have his own transmitter, given that you can pass the HAM exam (if not you shouldn't be fooling around with wireless equipment anyway). Wireless links can be bought almost off-the-shelf.

      IMHO the communication scheme itself is a lot more difficult. This can be understood easily by looking at the evolution of wireline modems: they started at 150 (or so) bps and worked their way up to 33kbps (higher rates use special tricks). All the time the medium remained the same, only progress was in the digital layers. For the same reason, I don't think it is fair to say 'wireless problem solved, halfway there'.

            I'm not sure what the maximum power output is in the United States, but here in Sweden, a licenced radio amateur operator can put out up to 1 kW or so without any additional license.

            And, being a ham radio operator, you don't actually have to use equiment certified by anyone. Part of the reason you have to take an exam to become a ham radio operator, is to demonstrate they you know what you're doing. Amateur radio is the only service I'm aware of (other than possibly the military) that doesn't require its users to use type approved equiment.

            Now CB radio however, that's a completely different story. Any idiot can go to his local electronics store and buy himself a CB rig capable of putting out 5 W of power with a microphone and jabber into it.

            Now if he is a CB radio operator -- if he's using any amplifier at all, it's probably very illegal -- and usually of poor quality with lots of nice harmonics.

            So how can you tell if your friendly neighbour with the amplifier is a licenced radio amateur running QRO on HF, or if he's an illegal CB operator?

            Well. One way to tell is by the way he talks on the radio. You said that you have equipment capable of receiving his transmissions (your computer speakers :-)

            According to regulations, all amateur radio stations must identify with their callsign and the callsign of the other party on a regular basis in their contacts. Listen for callsigns -- usually 5-6 characters long with one or more numbers in it -- my callsign is SM0YUF, somebody in the US would probably have a callsign starting with A, N or W, or maybe some other letter that escapes me at the moment. You can look up who owns a certain callsign on http://www.qrz.com/ [qrz.com].

            If the transmissions contain no callsigns whatsoever, chances are that he's in fact an illegal CB operator, in which case, in theory, you could contact the FCC using the magic word "CB" rather than "ham radio", and hopefully you might make some progress.

            Hope this helps. Oh, and do look into those papers with toroids and ferrites. If he is in fact a licenced radio amateur, he is well within his rights, and your equiment is shoddy. Sorry.

    So, what I would like to know is: why is there no cell phone specifically designed for home use? If the cellphone companies want us to get rid of landlines why have they not designed phones that can actually be used in a home environment?
    I was a sucker for car phones: much better reception, easier to hold and work with than those tiny cellphones.
    I want a 'stationary' cellphone for the house with an antenna on the roof for excellent reception so I don't have to use my tiny little cell phone.

  • According to TFA, this is just a cordless phone, which means you would have to carry around both this handset as well as your regular cellphone unless you know you won't be out of range on a given day. You still have to pay for your landline. More appealing to me would be if somebody made a high performance tabletop cellphone (with external antenna) so I could ditch the landline altogether.
  • From TFA:

    Either way, if you want to use your landline anywhere in town (mountains and buildings aside)

    That means it doesn't work inside any building, including your own apartment. Sorry, doesn't work for me.

    This is not a Samsung model. In fact it is made by several Chinese factories as fakes of Samsung, SENAO, etc. They normally use HAM radio frequencies or comercial VHF/UHF. Due to the fact that they are only certified in China it is illegal to use in most countries.

      That would explain the results you get when entering "Samsung Super Long Range Phone" into google. It's really a shame we can't convince /. editors to google the subjects of stories before submitting them. I guess that's our job.

      They normally use HAM radio frequencies or comercial VHF/UHF. Due to the fact that they are only certified in China it is illegal to use in most countries.

      This explains why you don't see these for sale in the US anywhere... it's clearly not a new product, and if someone did come up with a way to do this legally ( and in a manner that would allow everyone in town to have such a phone- say a wide-spectrum mesh network device or something ), it'd be big, big news. Too bad this isn't something like that- instead, it's just more crap to clutter HAM frequencies and/or screw up over-the-air broadcasts. Only the stupid and extremely anti-social would even consider purchasing such a thing in most developed countries...

      Me, I'm not to afraid of low-level RF emissions- I think my cell phone probably won't give me cancer... but you do have to wonder what sort of radiation *this* sucker puts out...

    If you operate one of these devices in the U.S., and it operates on ANY frequency used by the military, government, business, or amateur radio, you will be hunted down and taken out--by the FCC.

    The price of the unit may be cheaper than cell phone bills, but add on that $10,000 fine and seizure of the equipment and it gets real expensive real quick.

    And in case you think you're safe because it's in an amateur band, you should note that amateur radio operators practice RDF (Radio Direction Finding) or "Foxhunting" for fun. They will hunt you down, and the FCC accepts evidence from licensed operators in cases against violators.

  • Does anyone know how many channels this device is capable of?

    What frequencies does it run on?

    I see it highly likely that if this thing gets popular, it will end up similar to the original wireless phones in the early 80's with one antenna on a high tower that covers an entire city. Unfortunately, only 30 people would be able to use it in a city at one time.

    4. On July 27, 2001, agents from the Miami Office visited Lightning's retail store located at 231 E. Flagler Street, Unit #1, Miami, Florida. The agents saw several long-range, cordless telephones on display at the store, including a Super Phone CT-9000, a Prolink CT-6000CID, and an Optima OP8810. A salesperson
    offered to sell one of the units to the agents. The long-range cordless telephones displayed at the store were capable of causing serious interference to aviation communications and were
    not approved6 by the Commission for use in the United States.

  • I saw nothing in the article that specifically states that, but apparently so, by that FCC complaint.

    From TFA:
    Update: Keep in mind, this sort of power may be violating FCC regulation.

    My understanding is that transmitting ANY radiated power in that (2-meter) band (or most other bands) that can be detected by others is illegal without an amateur radio license, and the way this thing operates, I'm not sure it would be legal WITH a license.

    TFA didn't say, but I'd hope this thing is not being sold in the US

    I looked a bit farther on the site and found a spec page for the phones. It says they run in the 240-450Mhz range. And it says the transmit power is 1500mA??? That would mean the unit would be in UHF channels and something in the order of 30x more transmit power then the typical "legal" non-licensed deviced in that band. (correct me if I'm wrong on the 30x more powerful part but it's certainly alot more powerful than your typical comsumer or even pro-sumer wireless gear in that range)

    There is no way, even if this works for 30 miles, and they fix interference problems, and it is declared safe for use; there is no way the cell phone companies will alow people to own them. They will use thier lobbys to outlaw cordless phones with a long range. If my phone worked 30 miles from the home, I would not need my cell phone. Cell phone companies will do the same thing telcom companies do, when they lobby to make it illegal for small towns to provide free internet access. Life is all about money, and the big corporations will not allow for anyone to take away from their profits.

    Yes, I know the phone as currenly configured violates FCC regulations and a bunch of Ham Radio enthusiasts would hunt me down and kill me if I used one.

    However, if one was configured to work within FCC standards, paired with VOIP and a PBX this would be a godsend for a lot of companies and universities that have employees that are far-flung and travel a lot.

    My company has a campus with 5,000 employees served by a large number of desktop support technicians weilding pagers and cell phones. With devices like this, the technicians could call each other or anyone in the company over the radio waves for free instead of using cell phones.

    I imagine such an application would face strong resistance from the cellular providers, who would resist in the form of dollars into the campaign accounts of politicians responsible for oversight of the FCC.
