Problems solved by technology

However, adding switching functions may add unnecessary latency (delay) and jitter to the connection from the central location to the antenna site
Latency affects the timing of round-trip responses to modify user equipment, thus reducing the maximum cell size, while jitter in the modem can greatly impair the modem

Abstract

In one embodiment, a cloud radio access network (C-RAN) includes a first plurality of antennas and a first plurality of radio remote units (RRUs) coupled to the plurality of antennas. The C-RAN also includes a first plurality of broadband base units (BBUs) and a first photonic switch optically coupled between the first plurality of RRUs and the first plurality of BBUs.

Description

[0001] Related Applications Cross Application [0002] This application claims priority to U.S. Patent Application No. 13 / 922,683, filed June 20, 2013, entitled "Systems and Methods for Sensitive Cloud Wireless Access Networks," the contents of which are incorporated herein by reference into this article. technical field [0003] The present invention relates to a communication system and method, in particular to a system and method of a cloud wireless access network with sensitive traffic (Traffic) processing. Background technique [0004] With the launch and rapid adoption of new mobile broadband services, the demand for cellular telephone services is increasing. Therefore, it is desirable to increase intra-cell bandwidth capacity and cell density. The density of base stations is increased by reducing the cell size and increasing the transmission bandwidth per cell, which is achieved through higher bandwidth per carrier throughput and the use of multiple carriers in each...
