I'll believe this when I see it. There is no way a 100 mW transmission can traverse 60 miles (line of sight I presume -- useless), especially with all the interference in the 2.4 GHz band. Software is good but not that good. | |

TX | Re: Why not for the US? It is possible, LOS is the keyword. Ever thought how the 1W transmitters in the directway satellite systems can reach a satellite that is 22,000 miles away? LOS... | |

| Re: Why not for the US? Only 1W? How high up are those satellites? I've ran setups to 23,000miles and we'd have to push a few dozen watts just to get through heavy clouds and a lot more if it was raining really bad.

| Re: Why not for the US? I agree with you, but remember,in a sat terminal you are amplifying a wide spectrum(multiple channels). A direcway, any other residential sat setup only needs to amp a small carrier.
It is just like many Wireless ISPs that use 5 and 10MHz channel widths to increase range instead of the standard 20MHz Wi-Fi channels.
I was a direcway customer about 5 years ago and used to lose sync every time a dark cloud got in the way.
BTW, I still have the equipment, If anyone wants it. | |

| Yes, but antennas are hardware. Wi-Fi gear uses a half-dipole with a tiny 2.16 dBi gain and this article claims using existing Wi-Fi gear. Also consider the carrier frequency, noise figure and lack of line-of-sight (multiple reflections).
Allow me to remain a skeptic... | |
