Satellite Uplinks for the Masses

kgeiger (1339271) 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."

Wrong end of the problem (1)

Spazmania (174582) | about 2 years ago | (#41089907)

The solution to this problem lies in where you place the constellation. Satellites in low earth orbit (a few hundred miles) don't take much power to talk to with a minimally directional antenna. Think 60 to 90 degree beam width; you just vaguely point it in the right direction. Takes care of the speed of light problem too: latency isn't so bad across a 1000 mile round trip.

Shooting at geostationary orbit 22,000 miles away that you have to share with 3/4ths of a continent just doesn't work well for 2-way communications. Super smart antennas aren't going to change that.
