Abstract: A method for transmitting data through a multi-media communication network includes converting transmission entities into data symbols at a first communication device, transmitting the data symbols from the first communication device to a second communication device through at least two different types of communication media using only lower PHY layers of the at least two different types of communication media, and converting the data symbols into transmission entities at the second communication device. A network implementing a universal data link includes a first communication device configured to convert transmission entities into data symbols, a second communication device configured to convert the data symbols into transmission entities, at least a first communication medium and a second communication medium communicatively coupled between the first communication device and the second communication device, and a first physical-layer translator configured to translate data symbols without converting the data symbols into transmission entities.

Abstract: A multiple-input multiple-output (MIMO) capable system is contemplated. The communication system may include a signal processor configured to separate an input stream into multiple signal paths to facilitate simultaneous transport through a communication medium. The capability to simultaneously transmit multiples signal paths may be beneficial in order to maximize throughput and/or minimize expense.

Abstract: Systems and methods presented herein provide for altering communications of a LTE wireless communication system operating in an RF band with a conflicting WiFi system. In one embodiment, an LTE system includes a wireless base station operable to transmit downlink communications to a UE in the RF band and to receive uplink communications from the UE in the RF band. The LTE system also includes a processor operable to detect the uplink communications from the UE, to estimate a location of the UE based on the detected uplink communications, to determine a communication capability between the UE and the wireless base station based on the location of the UE, and to downgrade the downlink communications from the wireless base station to the UE based on the determined communication capability to avoid interference with the WiFi communication system.

In order to reduce processing time and end-to-end latency, the physical-layer translator only performs demodulation and modulation operations, optionally also equalization.

Abstract: A system and method for optimizing the end-to-end latency transfer rates over an air interface employing a Multi-hop Relays (MHR). The present system and method provides fast signaling process when no Downlink/Uplink Bandwidth allocation changes are employed, thereby bypassing PHY/MAC/IP Stack processing. The solution is intended for the new generation of 5G millimeter band multi-hop relays.

Abstract: Systems and methods presented herein provide for improving communications when encountering aggressive communication systems. In one embodiment, a communication system comprises a wireless access point operable to link a first user equipment (UE) to a WiFi network via a contention based mode that directs the WAP to share radio frequency spectrum with other WAPs. The communication system also comprises a communication processor operable to query at least the first UE to determine aggressive radio frequency (RF) band activity by another communication system in range of the WAP, to determine that the aggressive RF band activity by the other communication system is pushing communication with the first UE via the WAP below a threshold level, and based on the determination, direct the WAP to switch to a contention free mode to communicate with the first UE in contention free mode.

Abstract: Wireless access network selection is contemplated. The selection process may include arbitrating use of a plurality of wireless networks according to their performance capabilities. The performance capabilities or parameters may be identified from information broadcasted from the wireless networks. Mobile devices capable of wirelessly connecting to the networks may identify the performance capabilities prior to connecting to the wireless networks, thereby enabling the mobile devices to more efficiently identify suitable networks.

Abstract: A method for allocating aggressive signal carriers in a target band of a wireless communication network is provided. The network includes at least one long term evolution (LTE) node and at least one non-LTE transmission source. The target band includes at least two adjacent pairs of contiguous radio frequency (RF) channels. The method includes steps of scanning each contiguous RF channel of the target band to measure a respective value of non-LTE RF energy therein, determining, from the measured non-LTE RF energy, that a first one of the contiguous RF channels is occupied by a non-LTE carrier, and allocating an LTE carrier to a second one of the contiguous RF channels, different than the first one of the contiguous RF channels, based on the determination.
