Multiple channels are aggregated. In an example embodiment, first data is transmitted on a first channel to a wireless device, and second data is simultaneously transmitted on a second channel to the wireless device. The first data and the second data are transmitted in a coordinated manner by aggregating the first channel and the second channel. Various example channel characteristics and combinations thereof are described. Different data allocation options for aggregated channels are described. Other alternative implementations are also presented herein.

This disclosure provides systems, methods, and apparatus for calibrating and controlling the actuation of an analog interferometric modulator. In one aspect, an electrode of a movable layer of the analog interferometric modulator may include a part for receiving a drive voltage, and an electrically isolated part. A voltage may be sensed from the electrically isolated part, and used to determine the position of the movable layer and/or provide feedback to the drive voltage.

A wireless broadcast system includes receiving a data a stream by a convergence module. The convergence module partitions and encapsulates the transport packets into MAC protocol data units such that a size dimension of the encapsulated transport packets matches a size dimension of the MAC protocol data units. The MAC protocol data units are then provided to a transmitter that is synchronized to a plurality of transmitters in a single frequency network so that each transmitter in the network broadcast an identical signal that includes the MAC protocol data unit.

A wireless broadcast system that collects content for distribution over a wireless communication network. The content stream is encapsulated into a stream of transport packets for broadcast over the wireless communication link. The stream of transport packets are simultaneously broadcast as part of an identical signal from a plurality of synchronized transmitters in a single frequency network. A receiver acquires the broadcast signal and synchronizes to the signal. Once the receiver is synchronized to one of the transmitters in the single frequency network, the receiver can receive signals from any, or multiple, of the transmitters in the network without re-synchronizing.

A method for reducing call dropping rates in a multi-beam communication system. The multi-beam communication system includes a user terminal, a gateway, and a plurality of beam sources, where each beam source projects a plurality of beams, and where a communication link between the user terminal and the gateway is established on one or more beams. The method according to the present invention relies on a messaging protocol between the gateway and the user terminal. Based on messages sent from the user terminal to the gateway, preferably on a preselected periodic basis, the gateway can determine the more desirable beam(s) for transmitting data or information to the user terminal. The messages sent from the user terminal to the gateway contain values representing beam strengths as measured at the user terminal. The gateway uses the user terminal measured beam strengths to select the beams that should be used for transmitting data or information to the user terminal. The beams that should be used are the beams that if used will decrease the call dropping rates and provide a desired level of beam source diversity.

A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.

Methods and devices for operating a wireless communication device that can communicate with at least two different wireless networks using a single radio frequency modem are described. The communication device attaches to a first wireless network through the radio frequency (RF) modem, and then detaches from the first wireless network at a predetermined time before a start time of a selected event on a second wireless network. The device attaches to the second wireless network using the same RF modem before the start time of the selected event and collects at least a portion of event data associated with the selected event. After collecting at least a portion of event data, the device detaches from the second wireless network and re-attaches to the first wireless network.
