In-building wireless (IBW) is an evolving technology that has grown to meet the demands of many commercial building owners, managers, and tenants. The majority of cell phone calls are initiated inside a building, so expecting reliable cell phone service inside commercial space is a growing demand. Many customers are realizing the traditional cell phone network of outdoor towers does not penetrate effectively into buildings, thus in-building wireless was developed to create consistent cell phone coverage.
Distributed antenna systems (or DAS as we refer to it), work similar to how a Wi-Fi router does — except with cell coverage. Think of it like this: If you just have one wireless router in your home, then Wi-Fi-enabled devices located closest to the device are likely to get the strongest signal and best connectivity. There may even be a few “dead spots” in your home that get a very spotty signal or can’t pick up the signal at all. To resolve this, you can either move your wireless devices closer to the router, which isn’t always convenient, or you can add additional routers to your home to extend a strong Wi-Fi signal throughout it.
Signals Defense developed DAS Shield™ to help create a more efficient in-building wireless network. By insulating a building from outdoor RF interference, in-building wireless systems don’t need to compete with an outdoor signal. Especially in densely populated urban areas, where significant wireless traffic exists, DAS Shield helps your in-building wireless system work as planned.
