Only 1W?
QUESTION:
What's the power for Cassini's transmitter?

ANSWER from FAQ on June 3, 1999:
It's 20 watts. Received at the DSN antennas, the signal power is 10 to
the -16th (0.0000000000000001) watts. From Saturn, the signal takes
about 1 hour and 20 minutes to reach Earth.

Conclusion: You don't need a whole lot of power to send a signal.... and to receive a signal, you need even less. ;)

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.]]> http://www.dslreports.com/forum/remark,18080042 Wed, 28 Mar 2007 20:51:31 EDT Re: Why not for the US? http://www.dslreports.com/forum/remark,18079118 exocet_cm :

Yuck - do yo really want to use a toothbrush that is several months old?
Wait, there is a lifespan on toothbrushes? I don't replace mine till I go to the dentist and I have teeth in great shape and clean too (according to the dentist... and my girlfriend).

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...]]> http://www.dslreports.com/forum/remark,18078973 Wed, 28 Mar 2007 17:15:05 EDT Re: Why not for the US? http://www.dslreports.com/forum/remark,18078939 GlennAllen : Two months?!

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.

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.

The price difference (15,000.00) vs. (700.00) is a no brainer, why anyone would choose wimax is beyond me. Of course, that's assuming this works as advertised..
