Why are Wilson Electronics solutions considered commercial grade?
Wilson Electronics has been in the electronics manufacturing business for
decades.  They have their own in-house engineers that design their products.  
Most product assembly and testing is done in-house.

Amplifiers are housed in strong metal casings that are designed to operate in
extreme conditions, not inexpensive plastic that is prone to crack and fail.

Many carriers throughout the country use Wilson amplifiers because they are all
FCC and IC type accepted.  They also pass the most stringent CDMA testing.  
Wilson amplifiers also have built-in patented oscillation protection circuitry that
helps insure proper operation within the carrier network.  Wilson amplifiers are
tower friendly and produce a very high quality signal.

Products are tested before they leave Wilson Electronics.  This helps insure a very
low rate of returns.

All components are designed to fit together.  Cables come with high quality
connectors for easy installation.

Wilson is known for having some of the best antennas on the market.  They have
patented ground plane technology that give their antennas superior performance
over their competitors.

Wilson is 100% focused on cellular amplifiers and antennas.  This is their business
and has been for many years.
