Abstract
An integrated antenna distributed system incorporates various types of communication signals, such as mobile communication signals, public safety signals, Wi-Fi signals, and other types of communication signals. Such a system uses a single reference signal to support MIMO using a single optical cable or a single fiber optic cable, and a signal from a remote location, to support commercial telecommunication services and Wi-Fi services simultaneously. The reference signal is used for frequency stability of remote units (RUs) connected to the head end (HE). For example, a reference signal is selected and sent from the HE to RUs, a bandwidth and frequency conversion of signals to be transmitted is specified and/or performed, a RU receives the converted signals and the reference signal from the HE, where the converted signals may be frequency or band-constrained, and the converted signals are converted at the RUs back to their original frequencies or bands.
