Abstract

Disclosed is a multi-frequency multi-mode distributed access system, comprising an access unit, distribution convergence units and remote coverage units. The access unit is capable of accessing radio frequency signals of more than five frequency bands, covering access to source signals in the frequency band range of 300MHz to 3.5GHz, performing digital signal processing on the source signals, and then performing data compression and transmission to the distribution convergence units or the remote coverage units, so as to achieve the goal of source remote transmission coverage. The one system is used to solve public network signals, special network signals and wired services, as well as functions which traditionally only multiple systems could complete. Compared to traditional access systems, costs related to property coordination and construction, provisioning and maintenance management are all reduced.
