Re: Wireless users, READ THIS!

Are there any electrical transformers across the field of view?
EMI "Electromagnetic Interference" can limit the range that a signal will travel. Antenna placement is critical to this issue. You do not want to shoot a signal directly accros power lines, either shoot over or below them.

superdog1, thanks for a really fine primer on WISPs. I rely on one WISP totally, therefore I'm very interested in any and all info on how they work.

Just for your info, though, my WISP's tower is about 12 miles away (as you may have already read several times!). I have a rural (2 wire) electrical power line about 90 yards from my antenna and my signal LOS is directly beneath it. About 1 mile away is a HUGE multi-megawatt powerline and my WISP's signal (Fresnel zone) goes right through it. Yet, my signal strength and quality is terrific, especially with my amp. Without the amp my system works just as well -- but I like to see the increased numbers with the amp!? However, you are probably right about the dangers of the power lines -- my reception "could" be a whole lot better without them!

Regards..........

If You do a search for amps in this forum and others, You will find that amps are not a good thing for the most part. The paragraph that You quoted was not mine, it belongs to this man:

I just thought I would give credit where credit is due, and I do agree with 99% of his posts!:)

Here is the post I am referring too:»Wireless users, READ THIS!
Dear Sir,
After doing a cut and paste on Your entire post and using it as a "sticky" post at the top of the page, I hope I have not offended You by not asking Your permission. Thanks in advance for making a post that I guess I was just to lazy to type?. All of the things that You listed in Your small "novel" should be a guideline that every person thinking about starting a WISP should read!. I may even call it a "bible" for startup WISP's. Thanks again for taking the time to "Set the record straight", as it was needed.

Any security questions for new wisp?

Thx for great info - especially suggestions on what to ask potential wisp. I'm just getting started with wireless broadband and was looking for help with choosing a provider.

Security is as big an issue to me as speed and reliability, but I'm not sure how to tell if a wisp does use good security practices.

Any suggestions for questions or methods to determine if a wisp uses wireless security "best practices" before signing up with them?

Can I require that they use WAP instead of WEP (since my router supports WAP)?

Should I be worried if they don't have an Acceptable Use Policy in place to deal with bandwidth/spam/whatever abusers?

Also, is there any list of things to check to verify that the wisp is using good, secure settings after they do the install?

Yes!, It could be a major problem, as other users could stop on Your bandwidth.:D

About antennas and MORE power!

said by HostingShack:

i would say try a 24db antenna, that radio is nice no problems with that.. if you upgrade the antenna and still have problems the AP is overloaded during the day, there is nothing you can do accept ask your wisp to upgrade already!
That radio with the antenna that is on it has no problem doing 12 miles with LOS(Line Of Sight) depending on the sector or base antenna it is shooting at. If in fact the link is good, a higher gain or larger antenna will not help. Latency in a wireless network is determined by quite a few things, but with all due respect to HostingShack See Profile, the antenna is usually one of the last things to cause it?. Poor link quality due to obstructions and other factors(Do a Google on Fresnel Zone) seem to be a major problem, as most WISP's will not take the time to make sure the path is clear, and then the easiest remedy in their minds is to do a "Tim the tool man" approach, and just use more POWER, which is the worst thing to do.
I did a cut and paste of this for a reason, as I want everyone to understand how power and antennas work. If You are using a WISP, and they come out to Your location and try and use an amp, I would run, not walk, as this is a bad idea. the same thing applies if You buy an amp off of ebay and install it thinking it will give You better speed and latency, or a larger antenna. It just doesn't work out 99% of the time. There are reasons for every problem You have whether it is a wired or wireless connection, and doing poorly engineered cures are not good.

@comcast.net
I have used cable broadband for many years now , but there is a WISP here in my current area, They offer residential service that is 1000kbps up and down,my current broadband is Comcast and I have 384kbps up and 4000kbps down.
My question is: I am an online gamer and am wanting to know if the additional upload speed and lower download speed would balance out my game play, or will it not help me at all??

The best answer I can give You is no, as good game play comes with good ping times or latency, and NOT the amount of bandwidth You have once Your connection speeds get above 128k up or down. If You are happy with Your current online experience, I wouldn't switch?:)
