Report Summary:
The Wilson SIGNALBOOST cellular amplifier is one of the best accessory items that a person that depends on their cellphone could possible buy. In cases where a successful connection or uninterrupted phone conversation is of the highest priority, the SIGNALBOOST ensures that if a signal is available it will be amplified and once amplified it will not be dropped except in circumstances where the signal suddenly becomes completely unavailable. The most impressive feature of the unit we tested is the fact that setting the system up is easier than anything one might expect out of so useful a device. The manual, while clear and consice is also unnecessary - as the system is easy to put together. The new Velcro based universal induction connection is hassle free and dispenses with custom connections. This feature has another plus- you can use the one connector for several handsets, allowing a group of persons to share one SIGNALBOOOST, even if they have different power connections. While the unit is typically powered from an automobile's 12V DC socket, it can also be powered from any portable/mobile 12V Battery- making it useful outside of the automobile. The two antennas we tested were equally effective and wiring them into a car's door is a small inconvenience that need only be performed once. Strong magnets attach the antennas to the roof of a motor vehicle for secure mounting.

Introduction:
Mobile wireless telephony has become the de facto method for communication . With more than 2B (Billion) mobile phones in use world wide, it's easy to see why we depend so heavily on this technology. Unfortunately, finite battery capacity and sporadic service interruptions plague an otherwise smooth system of voice and text communications. Even if battery power is sufficient, so called 'Dead Zones'- regions of poor or no signal transmission are a constant threat to reliable communication. Simple and effective signal boosters capture and amplify weak signals and make them useful as well as strong for the duration of the user's call. Though such devices may easily be taken for granted when signal strength is typically good, their value is inestimable in circumstances that can mean the difference between danger and safety, or life and death. From the point of view of anyone using mobile phones in remote locations, they allow for trouble free communication on a daily basis. For the stranded individual or emergency responder on mission, they can mean the difference between life and death.

Test Plan:
The objective of our test was to define a region and circumstances that resulted in very poor signal strength and using the Wilson SIGNALBOOST, measure the change in signal strength. Our method was simple. We would use the graphical signal strength indicator built into our test handset's interface to measure signal strength before and after using the Wilson SIGNALBOOST. We tested the system in three circumstances:
1) Dead Zone in open roadway
2) Dead Zone caused by architectural obstructions
3) Dead Zone cause by interference or poor line of sight in building interiors

Results & Conclusions:
1) Dead Zone in open roadway
In the case of a certain Dead Zone in a local town, we observed that connecting the Wilson SIGNALBOOST to our test handset (Samsung SGHT809), resulted in a marked and immediate improvement of the signal from zero (0) bars, to six (6) bars within the typical 60 seconds it takes for the booster to have effect.
2) Dead Zone caused by architectural obstructions
In the case of poor signal strength caused by partially underground locales, we observed that connecting the Wilson SIGNALBOOST to our test handset (Samsung SGHT809), resulted in a marked and immediate improvement of the signal from two (2) bars, to six (6) bars within the typical 60 seconds it takes for the booster to have effect.
3) Dead Zone cause by interference or poor line of sight in building interiors
In the case of poor signal strength caused by the architecture of a high rise building, a window mounted antenna tethered to a battery powered Wilson SIGNALBOOST resulted in a marked and immediate improvement of the signal from two (2) bars, to six (6) bars within the typical 60 seconds it takes for the booster to have effect.

Items of Note:
- The Wilson SIGNALBOOST has no negative effect on signal strength. Its use simply ensures that dropped connections are much less likely to occur
- Careful antenna mounting and positioning is crucial to effectively capturing a usable signal. The antenna must be mounted in such a manner that it can properly capture signals emanating from cell towers. The radiation pattern of the antennas must therefore be respected with horizontal or obstructed mountings avoided.
- For un tethered use away from automobiles, portable batteries must be used to power the unit. These batteries can be rather pricey as the smaller NiMh and Li-Ion packs come with a hefty price tag. In addition, these battery packs must be recharged after a period of time- making them limited in situations of long duration.
