| Re: hmmm..... Except that unless you have an extremely high transmit and/or receive location you are not going to get anywhere near 60 miles LOS. The curvature of the earth makes sure of that. The 'world record' referenced by Karl Bode  used two mountaintops. How many regular users have a couple of 7500 foot mountain peaks laying around?

| well, considering in general terms, the radio distance is defined as O(ptical) = sqrt(2h(r))+sqrt(2h(t)), where O = distance to optical horizon, and h=(r)receiver height, and h(t) is transmitter height. So assume the antenna is 20' at both sides. The optical distance would be approximately sqrt(2*20) + sqrt(2*20) = Appx 12.5 miles.
Now we calculate the loss.
PL = 117 + 20log10fMhz-20log10hthr+40Log10D
Where 117 = Constant
2.4Ghz
20' and 20'
Distance of 12 miles
So it's about 175db loss over that distance. Thus, the antenna is the key, because with a 175db loss, the antenna is going to have to be pretty tight.

| Why not for the US? I can see a great need for this, this would allow people in rural area's to get affordable broadband. 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..

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. | |

| 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... | |

1 edit | Re: What? This WiFi and its special directional antennas and software is designed to connect distant access points and not access points and end users. It is like the old Microwave towers that telcos used to transmit signals. After the data gets to the remote access point, then it must be distributed locally(presumably with std WiFi equipment).
Basically it is the use of relay towers that use WiFi to distribute signals.

| Re: What? Okay, the article is a little misleading then, especially the "it is regular Wi-Fi hardware but with modified software" part. Just relaying wifi signals doesn't seem very ground-breaking. Home routers in WDS mode already do it on a much smaller scale. | |

Someone at intel has the brilliant idea to "Beef up" a wrt54g, load DD-WRT on it, and using a couple of amplifiers - bump up the power to 10watts!
Now THATS why it's not going to be in the US. I pity the guy who lives next to the tower-of-power in Kazakhstan now!

| I wonder how they are going to deal with multiple user since there is going to be co-channel interference, and if it's based on 802.11 which is contention based there is going to be mega problems with that range. The hardware only supports so many wireless channels. | |

Last time I checked wireless used CSMA/CA and not CSMA/CD. AKA they already use Collision Avoidance rather than Collision Detection.
