Yes, 850 MHz is not 900 MHz, but the behavior was repeatable.
With barely any cell service and *without* using a dual-band repeater setup, I could use a mobile phone to call either another mobile phone or a landline 900Mhz phone in the same room, have it ring, answer it, etc...
Plug in the amp/repeater setup, see all or nearly all 'bars', use the mobile phone to call the other mobile, ring, answer, no problem...
Call the landline 900Mhz phone and the call would drop. Over and over. Unplug the 900Mhz landline phone and call... answer the call on a *wired* landline, no problem.

Someone has alot of spare time on thier hands. Guess you better get a 2.4 or 5.8 wireless . This has never been reported as a problem and I still do not think it is |

| Posted: Sun Feb 19, 2006 1:24 am Post subject: Need a Booster Antenna |
|
|
I am connected to Verizon Broadband with a Kyocera 650. I have about a -95db signal. I can connect to Broadband about half the time and it does switch back and forth between National Access and Broadband. I was looking at the Arc antenna from Booster-Antenna, but I noticed that it can with the Kyocera 650 connector built-in. I was planning to use the antenna on my Motorola E815 phone when I travel in a low signal area. Is the 650 connector on the antenna removable or is there an adapter that will fit my Motorola E815. I noticed that the Arc antenna from wpsantennas.com has removable connector end, how does this compare to the Booster-Antenna antenna?
Thanks. |

The Booster- Has removeable ends so you can use different adapters. I have not used the Arc myself but many members here are very happy with the Booster-Antenna . You cannot argue with success |

|
|
I have been reading a lot of good stuff in this forum, but I am still a little baffled on what I might need to get the best bang for the buck.
I am using an AIRCARD 580, NEW DELL D610 laptop without any problems
and I am running pretty well tunned windows XP.
At my house I get signal strengths that tell me I am on the "fringe" or border of a SPRINT EVDO tower.
When I get connected(latest SPRINT PCS CONNECTION MANAGER), I get the following:
Signal (1xEVDO): -120 DBm
Signal (1xRTT): -95 DBm
When I test my throuput at http://www.speakeasy.com/speedtest
(I highly recomend this site, seems be fairly accurate)
I am seeing through put like so:
DOWNLOAD: 100 to 120 kbs
UPLOAD: 50 to 60 kbs
I can sorta hold a signal, but occasionally it will drop and I will loose packets trying to pull up websites.
I want to boost my signal strength, get rid of my packet lose, and try to increase my download/upload speeds.
Please don't tell me hogwash about how improving signal strength won't help down/up speeds. I have heard that and read it 3 times today and you can't tell me you won't get better throughput, when your computer does not have to fight with droping packets. It ALL goes hand-in-hand.
So, need some suggestions on what I need to purchase to improve this connection. I would like some sort of outdoor antenna setup with a booster, since it is in my house. |

Our website is being rebuilt right now. but here is what you need
Dual Band amplifier kit $199.95
IAC067 adapter cable 9.95
Shiipping 19.95
Total 229.85
Lots of members here are using our amplifier here with great success. The kit comes with a 3 db Glass mount antenna . We sell all sorts of bigger antennas for even better performance. Call me at 716-818-5896 if you have questions

Gord,
Aprreciate your quick response. can you tell me the specs of the "Dual Band amp"? You got me curious. Also, my house is a one level and I will be wanted to put the antenna on my roof about 20ft staight up. |

Hello,
Since your 1xEVDO signal is so weak, an outdoor antenna will probably help in a big way.
Also, keep an eye on these forums for a firmware update to the AirCard 580 (it is coming). It will be like the recent Merlin S620 firmware update one and allow you to lock in EVDO signal - this will help many people that get a stronger 1xRTT or have the problem of bouncing back and forth between 1xRTT and EVDO.

Michael I doubt you can tell me but do you happen to know when the firmware update will be for the 580? Since I jumped the gun and turned my merlin back in to the Sprint store then next day I have tried to do a lot of research and talked to Gord.
I have a local contact who has agreed to help me and I am being sent a 580 to demo and testing til the end of the month. Since I am less than a half mile from a 1xrtt tower I have no doubt it will be my over riding signal as I have already found out. I assumed that the firmware would be the same and I could swith it to EVDO only. Uhh oh, you know what they saw about assumptions. |

Just hooked up my amplifier and antenna to my KPC 650.
Went from an RSSI of 85-90 before the Amplifier
With the amplifier I now have a steady 70.
Thanks Gordon for your quick shipping and easy set up instructions.
Maxximum Signal without a doubt

Michael,
Where do the RSSI #s come from? How do I obtain them for my situation?

With all due respect, this individual is reporting a specific problem that he is having, and your response is a rather cavalier comment about him having too much time on his hands.
Again, I will preface this by saying that I mean you no disrespect as it is obvious that you have a lot of satisfied customers. However, it is also obvious that you are not particularly familiar with the technical/engineering aspects of RF equipment or you would not make some of the comments that you do.
Scott's experience with interference between a cellular repeater system and a cordless phone is not only possible it's not at all unlikely. Yes, the frequencies are different, but near enough that portions of the cordless phone signal are likely within the receive passband of the cellular antenna and amplifier.
This is a *VERY* common phenomenon when 2 radio systems are operating in close proximity on nearby frequencies. It is known as de-sense, and what happens is the strong near-frequency transimitted signal of one system saturates the receive preamplifier of the other system, effectively reducing it's sensitivity to the desired signal.
Result, in this case, a dropped call.
Well I am at it, another of your comments that I take issue with, and I am paraphrasing but it's a remark I saw earlier in this thread, something like, "other manufacturers use confusing numbers like dbd and dbi when describing their antennas, but we just use db".
The *only* numbers that make sense when discussing antenna gain are dbi and dbd! The term db, by itself, is absolutely meaningless, since it represents a ratio, and a ratio is useless without knowing the basis of the comparison.
Saying an antenna has 10db of gain i's like saying this antenna is "1000% better". Unless we know WHAT it's being compared to, we can't evaluate the significance of that number.
The terms dbi and dbd tell us what it's being compared to.
Before I shut up, one thing that I think deserves much more emphasis than it has received in this thread is the length and quality of the antenna cable. Particularly at 1900mhz, signal losses in coaxial cable can be horrendous, especially the super-thin RG/174 often used on these antennas. Yes it's small size is convenient, but in many cases the loss in the coax far exceeds the gain of the antenna, producing a net negative gain. It may still work, but only because the antenna is in a better location (stronger field).
Example, a 5dbi gain antenna, with 10 feet of RG/174 at 1900 mhz. Loss in the coax is going to be 6-8 db, so the combined antenna/coax combination has a net negative gain! In situations where the run between the antenna and card is long, a preamp/amplifier can be a big help. For best results, mount the amplifier/preamp *at* the antenna, with as short a length of high quality coax as is practical between the antenna and amp/preamp. Make the long part of the coax run be between the amp/preamp and the card.
