Has anyone had much to do with them.

At work we have installed about 20 of them and just about all of them have quit working. Some have only lasted about 15 minuets. Its not only one person installing them. We had the Ford dealer do some, I have done some plus several other people. There are a few of them that have had no problems at all. As far as I can tell they are all installed correctly and exactly as per instruction.

Any help would be greatly appreciated.

Re: Cell phone boosters

Typically Wilson repeaters hold up pretty well. I have one installed in my office with a patch antenna. Also have one in my camper cause cell coverage is very spotty where its parked. They are both Wilson and have been in service for several years. Have had zero issues with them.

Not sure why your blowing them up. Are you installing recommended antennae? By someone competent in rf? Are the repeaters getting adequate airflow?

Re: Cell phone boosters

Splat they all come in a kit with all components included and yes they have plenty of air flow. I could see one or two failing but just about all of them. Something is not right and its baffling me.

Re: Cell phone boosters

Why are you using repeters when the wireless companies have extenders (mini cell sites that work off internet service convert call in top a voip call)

I have been iin the wirless industry for over 11 yrs and these are the coolest things I have seen! They only support 10 dedicated phones, they do require high speed iinternet and a gps signal ( for 911) but they work!

Re: Cell phone boosters

Puddle we have installed a boat load of these, in fact I am hesitant in telling you just how many due to multiple lawsuits the cellular companies have in trying to stop them from being used. They are a bottom end amplifier the problem isn't as much when they are used in a stationary setup but more when they are used in a mobile setup as the density of cell sites has for the most part closed the bad coverage areas in the more populace areas.

The problem with them in a mobile setup is that they amplify the signal of your phone beyond what the cell sites are prepared for so while you talk on your phone the phone is sampling other sites for a stronger signal so your likely to hit three or maybe four other sites while your on your phone, now lets triple your power and were talking about 12 site sampling cool huh? No when the phone samples it ties up resources it does not need and increases the likelyhood for a busy or dropped call which is unacceptable to the carrier, the other side is that the amplifier is dirty since its always on, it doesn't turn on or off when ever you hit the send button or end button so it muddies the frequency band.

They are a big hit in the oil fields where cell sites are few and far between, but I can tell you of at least three instances where the carrier has knocked on the door of people who have these installed at home, the carrier in all three cases threatened to call the FCC if they were not turned off immediately, ironically in all three cases the carrier installed one of their own product approved spot amplifiers but note all three of these were for the persons home not a mobile application.

I have had decent luck with Wilson but I wouldn't call them a top notch quality product with I would say a 20%-25% failure rate within 1 year in mobile applications, I would think that your failure rate is telling me something is wrong like maybe you have a frequency mismatch between your antenna and the amplifier giving you too much reflected power, but if you bought the kit with the factory antenna that would be unlikely, but they are a very simply setup with no way of dealing with high reflected. I think I would call Wilson and ask for help and Warranty replacements. I have moved into another area now and have not dealt with them in 2 years or so but when I did they were always very helpful and quick to send warranty replacements, but that was 2 years ago.

I know TMI right!:D

Re: Cell phone boosters

RBH the voltage converter is a 12/24 volt converter.

not enuf toys we are at the top end of Vancouver Island cell service is sketchy at best.

Lip thanks for the info. I am going to ask if the kits have had different parts added from the suppler. We have gotten most covered under warranty. Like you say the failure rate is way to high.

Re: Cell phone boosters

on another note, PJ if your vehicles are 24 volt and you are using a 24/12 converter it may help to add a relay or some sort of delay to the wilson amplifier, reason being is that converters are pretty dirty the power they put out can be all over the board specifically during power up and power down if there is a way to delay power getting to the wilson amplifiers a couple seconds or simply put them on a user activated switch it may help the wilsons last longer

I have no specific knowledge to back this theory its just a hunch based on my past experiences with converters, more so on 12/120 inverters then 12/24 converters.

We have seen some Laptop computers pitch a fit when using 120v supplied by some mid/low cost inverters and were forced to upgrade to a higher dollar cleaner inverter for the customer, this was obviously not what the customer wanted to hear since they supplied the inverter but we proved that the inverter was the issue so not much to be said after that

The problem isn't when your in the high pop areas its when you are literally in the middle of no where, the problem is that since the pops are not there the cell companies obviously are not worried about covering the area completely, add to that that the oil industry moves, it can move twenty miles into an area with spotty coverage and have 100 workers there for a month, work around the clock, drill a hole top it and then move to the next location and do it again. While these areas may be within 200 miles from Denver they are 10-20 miles from a cell site and therefore are at the very fringe coverage of the system, no pops means no incentive for the carrier to cover the area, I think the solution eventually will be satelite cell phones but its going to take time to bring the satelite phone into the real world in airtime fees, internet coverage is another issue completely.

I could go on for hours on this issue, another possibility is if the oil industry could get some help from Department of Homeland Security in that if DHS feels the oil industry is a viable target it could open channels that would allow the use of existing communications systems that have more capabilities, the problem is that has not happened as of yet.

What you are proposing is just not a real possibility since the areas where these guys are working are 5 years behind the real world, doesn't sound like much to the layman but if you have been in the industry for 15 years then you know darn well that 5 years ago may as well be 1 BC, the industry moves so fast some areas get further and further behind

Re: Cell phone boosters

yeah thats the short version!! We see it constantly here in Colorado because the oil guys are mostly flatlanders where a cell site can cover MILES of flat land well welcome to the Rockies!! I believe PJ is in the same situation in Western Canada, Cell companies would have to put a cell on every mountain top, which would be great for these guys(and me too I would be RICH) but imagine the cost as compared to the return on the investment, so probably not gonna happen!

Re: Cell phone boosters

We were talking about this to day at work. It seems the pickups with the most problems are the ones with blue tooth from factory and all 2011 models. Could the blue tooth be causing the booster failures.

Re: Cell phone boosters

Anything is possible but its highly unlikely that the bluetooth would have anything to do with the amplifier failures, they are completely different frequencies, I'm having a hard time thinking of something else that could be causing an issue
