The IDRPT-9000 was designed to give you a cell tower experience with solid performance, superior audio and high data rates. When you introduce more than a single frequency into a repeater, it requires you to design a repeater differently and accept performance trade-offs. Some of these trade-offs include reduced distance reach, data rates and number of phones supported simultaneously. For small applications with a few users and a relatively close cell tower this might be acceptable, but XPANDAcell believes in a superior product, reliability and transparency  to the user.
