DIGITAL RADIO SYSTEM
First Claim
1. A thin radio client comprising:
- a radio frequency (RF) subsystem configured to be communicatively connectable to an antenna system, the RF subsystem including at least one of an RF transmitter or an RF receiver; and
an interface connected to the RF subsystem and configured to transmit and receive packets, wherein the interface includes at least one subsystem selected from the group consisting of;
a transmitter-configuration subsystem configured to reconfigure the RF transmitter in response to a received transmitter-control packet;
a receiver-configuration subsystem configured to reconfigure the RF receiver in response to a received receiver-control packet; and
a reporting subsystem configured to transmit a context packet including both data of a state of the RF transmitter and data of a state of the RF receiver.

Abstract
A thin radio client can include a radio frequency (RF) subsystem having a transmitter and/or a receiver. An interface can transmit and receive packets. The interface can reconfigure the transmitter in response to a received transmitter-control packet, reconfigure the receiver in response to a received receiver-control packet, or transmit a context packet including both data of a state of the transmitter and data of a state of the receiver. A digital back end can include an interface to exchange packets with an RF device. At least some of the received packets can specify capabilities of the RF device or state of the RF device. The back end can determine a control packet based on received packet(s) and on a policy governing behavior of the RF device, and transmit the control packet to the RF device. A method of operating a distributed radio system is described.

10. A digital back end comprising:
-
an interface configured to transmit packets to, and receive packets from, a radio frequency (RF) device, at least some of the received packets including at least information of capabilities of the RF device, state of the RF device, or RF signals detected by the RF device; and digital hardware resources configured to determine a control packet based at least in part on at least one of the received packets and on a stored policy governing behavior of the RF device, and transmit the control packet to the RF device via the interface. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of operating a distributed radio system, the method comprising:
-
receiving from a plurality of spatially distributed thin radio clients respective context packets, wherein each thin radio client includes a radio frequency (RF) subsystem and each context packet includes data based at least in part on the respective RF subsystem; automatically determining, using a processor, respective control packets for at least some of the thin radio clients, each control packet including information to control operations of the respective RF subsystem; and transmitting the determined control packets to the respective ones of the thin radio clients via a packet-based bidirectional interface. - View Dependent Claims (17, 18, 19, 20)
