Ever felt that your wireless network is not performing at its maximum capacity? Does your signal strength indicate that your connection is not as fast and reliable as it should be? There are some basic steps you can take to instantly improve your wireless experience...
You do not always need to go as far as replacing your antenna. Many people have found that by simply relocating the access point provides extremely satisfactory results. The location of your antenna is extremely important - you should move it to avoid obstacles and to give a clear "shot" to the rest of your network. You can even try raising the antenna. Additionally, there are a few basic steps you can take to ensure maximum network performance...
Use a Repeater
Using a wireless repeater is as simple as placing the device halfway between your access point and your computer. Make sure that you place the repeater a fair distance away from your access point. If they are too close together, a feedback loop can be created and damage the repeater.
Reduce Interference
Devices such as mobile phones, cordless phones or anything that transmits a radio frequency can possibly cause interference with your wireless network. Devices that use the 2.4GHz frequency range usually cause a problem. You should check if any of these devices are causing interference by disabling them and then assessing the performance of your network.
Upgrade Drivers and Firmware
Keeping up to date with the latest drivers and firmware is extremely important to maintain maximum performance. You should check for updates on your manufacturers website for your PCI, USB or PCMCIA wireless device. If you have a wireless router, manufacturers occasionally provide updates for the firmware of these devices. These updates are usually free and may increase performance.
You should aim for as much LOS (Line of Sight) between your antenna and computer as possible. Take note that the more walls and objects that are in between these devices will degrade the signal strength profusely.

Facts About Wilson Amplifier Performance
Facts About Wilson Amplifier Performance
-- UnwiredSignal.com
Understanding cellular amplifier performance is extremely important when researching different amplifier products on the market. At Wilson, we stand by our claim that our amplifiers perform better than any of our competition because we design and engineer them to work better than our competitors. After testing by our own engineering staff, we have an outside, accredited, independent cellular industry testing laboratory verify our test results with their own testing.
There are three major performance specifications that form the basis for a performance comparison: The first performance specification is receiver sensitivity, which is the ability of the Wilson repeater or receiver to pick up a weak signal from a Carrier’s cell site. Testing must be done with the correct criteria and methodology using equipment specifically made for testing cell phones. Wilson Electronics has the ability to do this type of testing in our engineering facility where we have a cell site simulator and a double electrically insulated radio frequency (RF) enclosure.
Once we test internally, then we have our testing results independently verified by an outside testing laboratory that performs tests for the major carriers and cellular manufacturers.
The performance standard we test against is the CDMA performance standard. This is the most complete and preferred testing standard because it tests for the weakest signal that will still give a usable, quality voice and data output from the test device with a 0.5% frame error rate (FER) or less. In other words, an amplifier with better receiver sensitivity can detect a weaker signal, which allows the cell site to communicate with the cell phone at a greater distance. The Wilson amplifier outperforms all the competition on the CDMA performance standard.
By using the CDMA performance standard as a baseline, a true comparison can be made between cell phone and amplifier performance. A typical cell phone must have a sensitivity of -104 dBm or better. The higher the dBm number a tested device gets, the weaker a signal that it can receive and pass the test. (For example, a -110 dBm level can pick up a signal 6 dB weaker than -104 dBm.) A 6 dB improvement in receiver sensitivity will allow an amplifier to pick up the same signal at twice the distance from the cell site. 1. Using the same CDMA performance testing standard, the Wilson Dual-Band Direct Connection Amplifier on 1900 MHZ has a -109.3 dBm receiver sensitivity, while the Digital Antenna DA4000 Amplifier has a sensitivity of only -104.2 dBm. That means the Wilson amplifier can pick up a signal 79% farther than the Digital amplifier on flat terrain.
Misleading sensitivity claims are used by our competition, which is why we test their products against ours. Digital Antenna claims their direct connect amplifier’s receiver has a sensitivity of -123 dBm. This higher number is meaningless because it gets higher and higher by reducing the received bandwidth during testing. The measurement must be done at the cell system bandwidth as the established benchmark and then be compared with other amplifiers using the same comparison criteria on the same CDMA cell site test set. This is the methodology we use at Wilson and the standard used by all other accredited comparison tests. That is Wilson quality in action.
2. The second performance specification is the Transmit Test, which includes open loop power, closed loop power, minimum and maximum power tests for CDMA to assure the amplifier meets CDMA specifications and will not harm the Carrier’s cell site. Some amplifiers such as the Richardson Electronics B800-1900-1 do not even meet the minimum power requirements for the cell phone being tested.
3. The third performance specification is to test for quality control and assurance. Wilson Electronics uses sophisticated automatic computer testing stations that run as many as 40 different operational tests on each amplifier before it is shipped out to our product dealers. This assures consistency that each Wilson amplifier and Wilson repeater system has been tested for performance and meets our quality control criteria before it is shipped out.
Our approach at Wilson Electronics is to follow these three performance specifications in determining the performance of our amplifiers. We publish the test results and make the comparisons against our competition available for product dealers and customers to make an informed decision about what product to purchase. We stand by the testing results that show Wilson amplifier products outperform the competition!

Brand new CB radio with alot of noise ground loop?
i have a cobra radio and a 4 foot firestik and brad new coax with a swr checker in line im new to all of this and i get alot of noise when the car is turned on but it is almost perfect with the car turned off. i also noticed that if i take the ground wire off of the cb with the antenna grounded and mounted like its supposed to be that the cb stays on.
this is driving me crazy
Thank You!!
my power wire is hooked p right im good with electronics i have a amp wired down the passenger side of the car so i ran my coax on the ohter side
the noise is not coming from the power because i can unplug the antenna and the noise goes away
Are your wires hooked up correctly?Black is ground,orange is constant hot and red is accessory.Your cb stays on because it will find the ground going through the antenna.You can also get a noise suppressor,any local audio shop should keep them instock.
