  1. U.S. manufacturer of long-range wireless communications products for the home and office Amped Wireless yesterday announced the release of their new flagship router, the R20000G, a high-performance Wireless-N dual-band router....

    I'm confused.... this is a router that has great range. But to use the internet you need to upload and download, even if you're just sending a request to view a webpage. So won't my PC or tablet or whatever also need to capable of this long range?

    I know it's possible (my phone broadcasts to a cell tower after all), but if our battery powered devices already have this range, why do current routers that are plugged into the wall have such a small range? I assumed it was signal quality and restrictions of the 2.4 Ghz band etc. All they needed to do was turn up the power on the signal?! Why aren't all routers long range?

    ok so 100 feet times 100 feet is 10,000 square feet right? so the radius of this is only 50 feet? how is this long range? I already get more than 50 feet with my belkin roughter.
  4. since we're dealing with a radius, then the area is pi times radius squared, not the square root of the area cut in half. so technically the redius is 56.4 feet. just a technicality, haha. the extra 6 feet doesn't do a whole lot in terms of making it any longer range, and the 10,000 sqft figure is clearly presented that way to provide some shock-value
  5. Shock value it is, or marketing bling for the uninformed. My bet is that this is no better than any wireless router, and may be even worse than some.

    I totally agree, I wonder what's long-range about a fairly average footprint?:confused:

    Right. Every packet sent or received must be acknowledged by the other device -- this is a fundamental design property of Wi-Fi and the reason high-power transmitters are useless on their own.

    There are only two things that make high-powered transmitters worthwhile: 1.) A more sensitive receiver or 2.) a high-powered client adapter

    Perhaps the R20000G has a more sensitive receiver. 5dB antennas are a start, but will make little difference. Unfortunately, higher gain antennas run the risk of making things worse unless they are directional and that would pose a problem for most consumers.

    I don't doubt the R20000G is a step up from a $30 Linksys router, but the claim it will make a huge difference in range is really is just snake oil.

    Wireless power line network adapters are where its at for most people, I believe.
  8. ha ha. Is ampeg for real? 50 ft radius for 180$. ha ha. Deceptive advertising at its worst.

    In all fairness, the average American home is about 2500 square feet. The median is even less.

    Also, radius is also not as important as diameter -- we aren't talking about a directional antenna. Many people will be able to put this in a central area and get more than just a 50ft pie wedge of coverage.
  10. I disagree with you for this operates on the same concept as the internet. You need to download more then you upload so a high power router makes sense. Uploading can be degraded and slow as long as the download is at full power.

    It doesn't work that way. We aren't talking about reduced bandwidth; moreover, we're talking about no transmission connectivity at all (or at best, intermittent)

    Even "downloaded" (received) data need to be acknowledged via "uploaded" (transmitted) packets. If you can't transmit to the Wi-Fi router, then receiving data from it is worthless.
     

  12. Except for two circumstances.

    1. You can set your SSID to whatever you want (and broadcast the name of your Business or 'something else') and you can update the SSID minute-by-minute to SPAM Ads.

    2. http://en.wikipedia.org/wiki/Wi-Fi_positioning_system

    Both of those are one-way communication via WiFi (and fairly useful).


    Other than those situations you would need an equally powerful Transmitter (and quality Receiver) on the other end to enable two way transmission; unless all the Satellites had directional Antennas (as in an Office or a (very) small village (third world Internet)).

    The one who owns the Router pays for the Internet connection and everyone else gets a free ride if the Router is open or the password is known (pass=SSID name). This works in my large City and I can use my WiFi Phone half a Block from my House (but it is slow). That saves huge on my Cell Phone Bill
