Radio access networks
First Claim
1. A communication system for a site comprising:
- remote units to exchange RF signals with mobile devices, RF signals comprising information destined for, or originating from, mobile devices; and
a controller connected to an external network, the controller comprising a scheduler to assign airlink resources to the mobile devices, the airlink resources being for transmission or reception of at least some of the information passing between the remote units and the mobile devices;
wherein the controller is separated from the remote units by an intermediate network, the intermediate network comprising a switched Ethernet network over which data corresponding to the information is passed between the controller and the remote units, the switched Ethernet network comprising switches and a network in between the switches for passage of the data; and
wherein the controller is configured to obtain information about data capacity demands in different areas of the site, and to configure one or more communication cells in the different areas of the site based on the information about data capacity demands in order to accommodate the data capacity demands, wherein the one or more communication cells are configured by changing assignments of a number of the remote units to the one or more communication cells.

Abstract
Among other things, a communication system comprising remote units and a controller is described. Each of the remote units comprises one or more radio frequency (RF) units to exchange RF signals with mobile devices. At least some of the RF signals comprise information destined for, or originating from, a mobile device. The controller comprises one or more modems and is connected to an external network. At least one of the modems is a baseband modem and is configured to pass first data corresponding to the information. The at least one of the modems is configured to perform real-time scheduling of the first data corresponding to the information. The controller is separated from the remote units by an intermediate network. The intermediate network comprises a switched Ethernet network over which second data corresponding to the information is carried in frames between the controller and the remote units.
