A review of US Patent 8,730,833 reveals the following details:

Title: Coordination of co-spectrum users with wireless broadband networks

Assignee: The patent was originally assigned to Empire Technology Development LLC. The provided information indicates a security interest was assigned to Crestline Direct Finance, L.P. in 2019 and a release of this interest in 2023, with the current assignee listed as Empire Technology Development LLC. However, the information also notes that the listed assignees may be inaccurate.

Inventors: Elliot H. Drucker

Filing Date: May 9, 2012

Issue Date: May 20, 2014

Abstract: The patent describes a technology that enables a low-power, limited-range communication system to negotiate with an overlying wireless network for the use of shared frequency bands. This coordination aims to protect the low-power system from interference from the larger network and vice versa, while minimizing the impact on the network's performance and capacity.

Overview of Independent Claims:

Claim 1: This claim outlines a method for sharing wireless spectrum. It involves a wireless device, which operates on a fixed or selectable frequency that is also used by a larger wireless network, detecting its own activation. The device then negotiates with the network to determine which frequencies it is allowed to use and is subsequently enabled to operate on those approved frequencies.

Claim 12: This claim describes a computing device designed for coordinating shared wireless spectrum use. The device includes a memory for instructions, a communication module for wireless network communication, and a processor. The processor is tasked with detecting the activation of a separate wireless device that shares a frequency with the network, negotiating the use of that frequency with the network, and then permitting the wireless device to operate on the frequency or frequencies authorized by the network.

Claim 18: This claim details a computer-readable storage medium containing instructions for coordinating the use of shared wireless spectrum. When executed, these instructions will detect the activation of a wireless device that uses a frequency shared with a wireless network, negotiate the frequency use with that network, and enable the wireless device to operate on the frequencies the network allows.

Claim 24: This claim describes a wireless communication network that coordinates shared spectrum use with non-network devices. The network is comprised of base stations, user equipment (UE), and one or more radio resource controllers (RRCs). The RRCs are configured to receive a notification from a UE associated with a non-network wireless device when that device is activated or intends to be activated. The RRC then negotiates the use of the shared frequency with the UE and informs the UE of the frequencies the non-network device is permitted to use.
