maybe you need something like these:

or this:

imo this amplification idea is crazy. what happens to the ppl with other wifi networks in your service areas?

I tried with dlb2300 no luck then I order hga no luck so I am in middle no where ... and my city regulation dont let me put higher then 30 feet ... so only way i got the signal using buffalo whr-hp unit Amp on and 10mW = 100 Mw if my calculation is right +12dbi bi-quad antena ... I dont know if i have any other choice ... every one welcome for your suggestion ... Lutful and Superdog I will keep it mind your info and Lutful I will set my rts to 128 Tomorrow I am going add another NLOS client about Total Est. Distance: 0.28 miles hopefully I got the signal with home maid bi-quad and whr-hp

Unless you reign in your many Buffalos using strict RTS control, you will have lots of collisions. You may also need to reduce EIRP in late fall when leaves are gone.]]> http://www.dslreports.com/forum/remark,16713565 Tue, 15 Aug 2006 18:47:19 EDT Re: How to Build a low cost cpe with build in amp http://www.dslreports.com/forum/remark,16713172 superdog : While I understand You are in a rough situation, I would warn You against running a totally amplified network?. With that much power in such a tight environment, You may have issues later on. You may keep frying the receive side of Your CPE's and You could also end up sucking in and amplifying noise which in the long run will render Your entire network useless? :uhh:

Just an honest question, not a flame starter.]]> http://www.dslreports.com/forum/remark,16710053 Tue, 15 Aug 2006 09:32:04 EDT Re: How to Build a low cost cpe with build in amp http://www.dslreports.com/forum/remark,16709327 SipSizzurp : I just got them today and I will test them some more and let you know. The problem that you have with 3000 feet of trees and houses will not get much better, even if you put a big amplifier on each end. 2.4 GHZ will be blocked easily by the obstructions and I do not think you will have much luck with more power or better antennas. They will help a little, but still will not be reliable in the end. Think of the wi-fi signal like a flashlight. If the light from a little flashlight cannot go through the side of a house, a great big spotlight will not get through either. The wall will stop all of the light. Your obstructions are going to stop almost all of your signal, even if it is very strong to start with. You need to find a place in the middle for a relay that can get service to each end. By the way, light and 2.4 GHZ radio waves are the same stuff, just a big difference in frequency.

Going higher did not make the signal stronger, but it made the laptop start dis-connecting. Even at 45 Mw the signal was very strong, and the radio was getting hot pretty fast. 30 Mw is the most I think you should set it for.

However one of forum member helping me with bi-quad antenna so I am gone make home mad bi-quad and try test on Wednesday and I will pass my result wish me luck ..... I can feel the good thing :)

Btw keep posting your result :) ]]> http://www.dslreports.com/forum/remark,16709190 Tue, 15 Aug 2006 02:37:01 EDT Re: How to Build a low cost cpe with build in amp http://www.dslreports.com/forum/remark,16709138 SipSizzurp : I just did some testing to the HP model. I was almost shocked at the improvement in performance over the regular model. It weighs several ounces more, and the on-board power amp has some real ZAP. At my test distance, the regular model set to 125 Mw was fluctuating 1 or 2 bars of signal on the laptop, and connect rates were 11 and 5.5 random. With the HP in the same place and set for 30 Mw, (DD-WRT on both radios) my laptop shows a solid 2 and bumps 3 bars with 18 and 24 mb connect rates. I've had it with netstumbler. It is crap. The primary scan screen only shows the Db level that it catches when it initializes, and does not update properly. If the signal gets stronger, it indicates the increase, but never follows it back down as the signal decreases. The green graph that plays midi music was pathetic and equally useless. Does anyone know of a decent alternative to netstumbler ? It is a broadcom internal radio. I saw another model of laptop with a broadcom site monitor utility that was superb, but cannot seem to locate it to try on my machine. Pointers would be welcome. It would be nice to hook these radios to a service monitor to see what they are actually doing. I am estimating the HP model's output at around 300Mw. Rahail, if you have access to any half-way point between you and the client, you might consider putting a relay station there.

An AMP only covers one side well. Good antenna gain always trumps more power becuase it covers both sides. Of course you have to reach the AP so if receive dB is good, the power needs to be adequate to return to the AP. One cannot assume that the return signal will do as well.

As to what antenna to choose, YMMV. I believe the general consensus is that a high gain panel will outperform the same gain in a dish when LOS is not to be had.]]> http://www.dslreports.com/forum/remark,16694902 Sat, 12 Aug 2006 19:14:18 EDT Re: How to Build a low cost cpe with build in amp http://www.dslreports.com/forum/remark,16694789 Rahail : NOt yet ....

One of my client 200 feet way from the AP NLOS I gave him one of this when he sign up WHR-G54S signal was (-81-85) ... he had lots of signal and packet lost ... then I decide to change his unit and gave him the hp version now his signal rssi about -46-59 So do you think this Build in AMP cant help me go throw lots of trees maby 5 few houses ]]> http://www.dslreports.com/forum/remark,16685458 Fri, 11 Aug 2006 01:58:07 EDT Re: How to Build a low cost cpe with build in amp http://www.dslreports.com/forum/remark,16685451 SipSizzurp : The only way to know if the link will work is to try test the whole distance. Normally you can eat through 1 or 2 trees with a warmed up station, but it all comes down to erp and blockage. 2000 feet of houses and trees does not sound very good at all.

NLOS is not a good thing. What is the obstruction that you have ? Have you done a field test to see if you can get a signal through ?

A 14 Db rootenna with RP-SMA antenna can be had for $42.20 at fab-corp or $37 at pasadeena in 20 Qty. I have used the little brother to this radio very extensively with raging success. DD-WRT allows ACK timing and very flexible RF output control. The regular model (whr-g54s) is under $39 at provantage and runs 125 Mw in hot attics and 36 Mb connect speeds with no noticable degradation of bandwidth delivery. I have run 13 units in attics (135 degrees plus) and a total of about 70 units for the last 5 months. Not a single lemon or failure at all. These Buffalo radios are very well made. I ordered 3 of these HP models yesterday just to play with and compare. I'm very curious to see how much better they are than the regular model. This will put you well under your target price of $100. With DD-WRT, all modes are supported including WDS, router, AP and true client bridge mode.
