A capability is provided for virtualizing control plane functions of a wireless core packet network (WCPN). A forwarding element (FE) is configured to provide a set of data plane functions of the WCPN. A virtual control element (VCE) is configured to provide a set of control plane functions of the WCPN. The VCE includes a set of virtual machines (VMs) where at least one of the VMs is configured to detect a condition associated with a tunnel, for a wireless terminal (WT), between the FE and a wireless access device (WAD) configured to serve the WT, and propagate, toward the FE, a message comprising a tunnel command configured to instruct the FE to at least one of install, remove, or modify a tunnel rule associated with the tunnel between the FE and the WAD. The tunnel enables the WT to access a packet data network (PDN).

One embodiment includes a method for determining a target location for a metro cell base station by calculating, via at least one monitoring device, at least one of a number of user equipments within a range of the at least one monitoring device and a radio frequency (RF) level of at least one macro cell base station. The method further includes determining, via the at least one monitoring device, the target location for the metro cell base station based on at least one of the calculated number of user equipments within the range and the calculated RF level of the at least one macro cell base station.

In the method, positions of a plurality of transmitting sources within a proximity of a base station are determined. A received signal spectrum of signals received at the base station from the plurality of transmitting sources are simulated. Inter-modulation distortion products are estimated based on the simulated signal spectrum. The estimated inter-modulation distortion products may be used in the design of a radio architecture. The simulating step may be repeated a plurality of times until an acceptable solution is found. Base station operating parameters associated with the acceptable solution may be selected for use in a proposed base station.

Techniques for use in designing, adjusting or operating a wireless network so as to provide a desired level of performance for the network. An optimization process is applied to a set of information characterizing the network. The optimization process includes at least a pre-frequency-assignment optimization stage, which is applied prior to assignment of frequencies to one or more communication channels of the wireless network. An output of the optimization process is utilized to determine one or more operating parameters of the wireless network, such as a base station transmit power or antenna orientation.

Techniques for use in designing, adjusting or operating a wireless network so as to provide a desired level of performance for the network. An optimization process is applied to a set of information characterizing the network. The optimization process is implemented as a multi-stage process which includes at least a frequency assignment stage and a post-frequency-assignment optimization stage, wherein the frequency assignment stage and the post-frequency-assignment stage are subject to iteration. For example, after an initial assignment of the frequencies in the frequency assignment stage, the post-frequency-assignment optimization stage may be performed, and based on the result of the optimization, at least one of the frequency assignment stage and the post-frequency-assignment optimization stage may be repeated. An output of the optimization process is utilized to determine one or more operating parameters of the wireless network, such as a base station transmit power or antenna orientation. The optimization process in an illustrative embodiment may be implemented as a three-stage process which includes a pre-frequency-assignment optimization stage, the frequency assignment stage and the post-frequency-assignment optimization stage, with one or more subsets of these stages being implemented in an iterative manner.

The wireless communication system includes antennas having electrically controllable downtilt angles and downtilt controllers associated with each antenna. The downtilt controllers receive instructions from a main controller, and adjust the downtilt angles of the associated antennas in accordance with the received instructions.

System and method for controlling antenna downtilt/uptilt in a wireless communication network

An RF apparatus (e.g., a wireless label) provides improved backscattering of an incident RF signal by utilizing a separate modulator diode, which connects across the antenna, to modulate the backscattering of the antenna. A separate detector diode connects across the antenna through an impedance matching network to detect modulated signals received by the antenna.
