Satellite Uplinks For the Masses

Posted by timothy on from the let's-see-the-pricetag-for-the-masses dept.

kgeiger writes "Intellectual Ventures has spun out Kymeta to develop and mass-produce their mTenna product line. mTennas are based on metamaterials like the invisibility cloaks discussed on Slashdot and elsewhere. Metamaterials enable beam-steering that ensures an mTenna remains in contact with satellites even during motion. Kymeta will use 'established lithographic techniques' to make them. IMHO, these antennas may be as big a leap for mobile computing and remote communications as the invention of fractal antennas was for mobile phones."

    Phased array stripline antennas have been done to death. To death.

    Says you. I happen to have one with me right now. I'm putting it against my head. Nothing is happening. Now I'll put the second one against the other side of my head while making sure that if I do pass out that my body will hit the submit button. Okay, big whoop, nothing is happe

  2. It's just a phased array by rgbe · · Score: 4, Informative

    This is just a phased array antenna (http://en.wikipedia.org/wiki/Phased_array). The applications of a phased array allow you to have a direct "beam" to the transmitting tower, which means that you can use significantly less power, and possibly transmit over a larger distance. The idea has been around for a long time, almost 100 years.

    It will be interesting if they get this to work, especially for mobile devices like laptops and mobile phones, because when you move your phone you need to immediately redirect the signal "beam" towards the transmitter / receiver. If you miss, you lose your signal. Not only that, calculating the direction of the beam and requires you to regulate frequency and intensity of hundreds of the transmitters on the phased array, this calculation will create a superposition of waves in one direction and cancellation of the waves in the other in the other directions. Hence a "beam" in one direction. The calculation of direction of the "beam" is computationally intensive, but I presume it could be optimised using a lot of hard coding.

    Invisibility cloak? I'll believe it when I see it...
