Welcome to In-Building Design a RF design company located in Fox Valley Wisconsin. Our goal is to help provide you with improved cellular reception for Verizon, AT&T, US Celluar, Sprint, and others in your building using I-bwave technology and professional amplifiers/repeaters. In today's world, we have all become very reliant on our cell phones. It is very frustrating to have a phone or number of phones in your home or business that do not work, as well as the costs and lost business. Cell phone reception can be lost or softened due to the distance to the cellular tower as well as building materials such as metal, concrete, or even trees between your phone and the cell tower. By installing a cellular amplifier or repeater system, the signal can be boosted back to a level that will get your calls and data through to the network. In-Building Design will work with you on designing a professional carrier-approved system that will be cost-effective as well as reliable. Once your design is done we will work with you on the installation process. In-Building Design will take the necessary steps to have your system approved.
