Re: It's a bad idea
I guess you don't really understand WiMax then.
WiMax uses the 2.5 (Licensed spectrum in the US) and 3.5 GHz spectrum...it's not WiFi...so interference is not an issue
As for "hacking"....doubtful...granted nothing is ever totally hackproof...once again...it's not WiFi.
"All kind of stuff"...please enlighten us about this comment...I'm certainly wondering what "stuff" is.
Speeds don't cut it? Not sure where you're coming up with that comment...let's repeat...it's not WiFi.
Honestly...you almost sound like a cable company "shill"...all kinds of filler...but no substance....just for the record...I don't use a WISP...I use comcast...and will most likely jump over to Verizon FIOS soon.
WISP's are for the last mile where the telco's and cableco's just don't want to go...not to mention having OTHER options for service is always a good thing for consumers.
You might want to educate yourself before spouting out some of the things you said. |

| While I largely agree with your critique of the parent post, you say, "so interference is not an issue."
I assume you say this because WiMax will be the only signal in that spectrum so there won't be intereference from other signals.
But does WiMax have some mystical ability to overcome weather, geography, and structures? With anything wireless, there will always be some type of possible interference...

| Taking the analogy further, coax, copper pairs and fiber are subject to "interference" from backhoes, lightning strikes, wildfire and some drunk plowing into a pole at 120 MPH. Nothing is "interference proof".
A properly designed microwave link has enough fade margin to remain up during weather events.
WiMax has one critical characteristic coax, copper pairs and fiber lack: Mobility. If it indeed comes to market, that is where you'll see it.

Yes it is non line of site. That is not to say that if your in a bunker that it will get a signal to you, it will not or if the tower is transmitting out and you are in a low spot that the signal might skip over you. The best way to look at it is like a transistor radio if the radio has the antenna up and sitting in the window you should get good reception. If it is in the center of the house or in the basement your signal will degrade. The distances that it will work at are 3-7 miles for fixed WiMax. The ones I have worked on had 4 to 6 T-1's feeding each tower with as many as 3 towers in one area. Not meant to compete with WiFi or DSL but can even be the back haul for WiFi. Keep in mind this is a solution for areas that are stuck with dial up only. |

Since WiMax will be run in a licensed part of the spectrum...you can up the power a lot more to deal with obstructions...now I'm not saying this would make it be able to penetrate say a mountain....but you can get further penetration into a home.
As for geography...WiMax isn't a P-t-P solution...its a solution for the end user. I would certainly hope if a WISP were to use WiMax they don't think they can just drop a base station into a location and service a 30 mile radius.
As for weather...you'd be pretty surprised at how well wireless when setup properly works in inclement weather...I don't think there'd be an issue this side of a hurricane/tornado/something of that magnitude.
Properly installed systems have fade margins for weather built in. |

All correct points. I don't even bother to study WiMax that much so I know next to nothing about the actual tech side of WiMax.
The one thing I keep seeing a lot concerning WiMax is delay after delay after delay, coupled with a lot of talk about how unproven the technology is.
If it is so great, why has it not been rolled out?
Am I to understand that it's better than a FTTH solution in your opinion?
Heh, cable shill. That is a good one. If I am a cable shill, then you must be a WiMax shill. I dunno where you got that idea from. Maybe because I have COX HSI for my broadband service? I bet you have a ton of "Jump to Conclusion" mats in your closet at home.
Please enlighten me as to why you felt it necessary to reply to me in such a manner? Are you just hostile? Do you feel the need to prop up WiMax at whatever cost to make yourself feel better about unproven tech? Something else?
The bottom line is that broadband sucks in America. IT SUCKS. All I want is real broadband. No more, no less. Isn't that what we all want, or am I mistaken? |

Perhaps this is arguing semantics, but topography and signal attenuation due to precipitation are totally different items from interference. A properly engineered point-to-point or multipoint system won't have availability issues due to weather. While you need to have line-of-sight for typical microwave systems, there are lower speed non-line-of-sight systems in use, so yes, wireless does have mystical abilities to overcome structures and geography  |

There you have it...this is exactly WHY I said what I did...you admit you know nothing about it...yet you make a post basically saying wireless in general is worthless and then go on to call WiMax a "stop gap" measure.
Like I said before...please educate yourself before posting about something you know nothing about.
As for being a WiMax shill...guess you missed the part about me being a comcast customer and will likely switch to FIOS. I merely defended WiMax as a last mile solution/solution where there is no cable/dsl/fiber/etc/ |

I won't disagree with that, there's plenty of WiMax hype However, don't throw out the baby with the bathwater; wireless in general has plenty of capacity and flexibility and is proven. Long haul point-to-point links delivered long distance calls in the 70s and 80s until fiber came along (that's how MCI got its start). Cellular carriers continue to use it today to backhaul voice and data traffic from cell sites. I think WiMax is an attempt to get the standards and ubiquity like 802.11, but with mobility, scalability, and protocols that can be used both in unlicensed and licensed spectrum. 802.11 has been both a boon and bane to wireless. It shows how flexible wireless technology can be, however it also shows what happens in out of control unlicensed spectrum or when people who don't know the first thing about RF engineering try to build a wireless network. I think WiMax will eventually succeed. Will coverage be ubiquitous in the US? Not likely. |

So no answer for my other questions? Just educate myself on WiMax before I talk to someone as knowledgeable as you? I don't buy it. Not at all.
Show me how great WiMax is. Explain to me or point me to some information that shows me how it works and how it's going to be the next big thing.
BTW - WiFI.. You got me there too. I was truly thinking wireless in general actually.
I still say WiMax is Stop-Gap at best. IF it even sees the light of day. (Which I sort of doubt) This is my whole issue with WiMax. Can you tell me that it will have what it takes to provide the bandwith needed to compete with a FTTH line? I seriously doubt it. It seriously jacks us around and puts us further behind in the broadband world when we waste time and effort on tech that is going to be obsolete in no time due to the fact that it doesn't have enough capacity.
It's all going to end up at the same place. Fiber. Fiber is the only thing that will work capacity wise. The good thing is that our idiotic government is probrobly going to kiss the hands of the big companies anyway and ruin the internet and broadband as we know it anyway. I guess that it all works out in the end right? At least we can count on WiMax. Oh wait, no we can't.... |

I think wireless has it's place, I agree with that. It's certainly nice to have from a convenience perspective. But it all goes downhill when you try to do anything other than surfing, e-mail, and basic downloading.
I have a Wireless G setup in my house. I use my laptop for the wireless connection and use it for some streaming media stuff. It works okay but i'm always fighting with other networks, losing signals, rebooting the router, etc....
When I am docked and plugged in with my trusty ethernet cable to the same router obviously, I have no problems at all and my speeds are much faster, not to mention I can stream movies again with no hiccups.
Wireless is great and has it's place, it's just not reliable enough to be a major broadband service in my opinion. |

Again, you're looking at wireless from the perspective of 802.11. 802.11 is merely one type of wireless technology. It's on an unlicensed frequency band so of course it's like the wild west. Of course you can't build a major broadband service on technology you get at Best Buy or Circuit City. |
