Systems, methods, and devices can be utilized to verify wireless local area networks (WLANs) using fingerprints. An example method includes identifying a received fingerprint comprised in an advertisement message that is received by a user equipment (UE) at a time and within a coverage area. A source of the advertisement message is determined to be a rogue WLAN by determining that the received fingerprint is different than a verified fingerprint transmitted by an authorized WLAN at the time and in the coverage area. The UE outputs an alert indicating the rogue WLAN.

Wireless network verification using fingerprints

A telecommunication device configured to select one of a plurality of network connectivities of the telecommunication device to use for transmission of a network packet is described herein. The telecommunication device may select the network connectivity based on user routing criteria, connectivity metrics, or transmission times. The user routing criteria may be dynamically updated during a communication or connection, affecting selection of the network connectivity for further network packets. The network connectivities may be respectively associated with different network operators. Also, the telecommunication device may select a first network connectivity for transmitting a first network packet and a second network connectivity for transmitting a second network packet. Further, the telecommunication device may select a first network connectivity for uplink communications and a second network connectivity for downlink communications.

Intelligent routing of network packets on telecommunication devices

A system, apparatus and method is disclosed for multiband wireless communication. Frequency bands and/or transmission formats are identified as available within a range for wireless communication. The system evaluates signal quality metrics for each frequency band and selects a communication method based on the evaluation. Multiple frequency bands and communication methods can be utilized by the system such that a combination of licensed, unlicensed, semilicensed, and overlapped frequency bands can be simultaneously used for communication. The system monitors communications and can report link performance for adaptive control of the selected communication methods.

Frequency band adaptive wireless communication

A computing system may utilize interfering signals of two or more wireless devices for improving communications involving the two or more wireless devices. These techniques and architectures may allow for improved spectral efficiency that enables a relatively large number of wireless devices to communicate among one another via receivers that share overlapping or adjacent frequencies. Such utilization of interfering signals may help solve a general problem involving, for example, co-channel interference (CCI) arising from densely deployed relatively small wireless communication cells for increasing communication throughput.

Increasing wireless spectral efficiency by leveraging interfering signals

Described herein is a radio access provider configured to communicate with wireless access devices over frequency bands. The radio access provider receives service priorities associated with active applications of the wireless communication devices. Based at least in part on the service priorities, the radio access provider selects blocks or channels from one or more of the frequency bands for a radio communication link for each of at least a subset of the wireless communication devices. The selecting may include selecting block or channels from multiple ones of the frequency bands for the radio communication link for at least one of the subset of the wireless communication devices. The selecting may also be based at least in part on signal quality metrics for the frequency bands, cross-correlations of the frequency bands, or power capacities of the wireless communication devices.

Application-based multi-band transmission

Methods and systems are described herein for adaptively adjusting the power level of a wireless transceiver and a cellular transceiver in a telecommunications device to correspond to the usage and data throughput of the device. The device can also dynamically enter different modes of operation based at least in part on network activity data usage on a wireless data network provided by the telecommunications device. By controlling the power levels, the power usage of the device can be reduced in order to increase efficiency of battery usage.

Optimized resource management in multi-radio access technology devices

A handover procedure can be implemented using a codec-specific threshold as a triggering event for the handover procedure. A mobile device can initiate a communication session with a serving access point (AP). The mobile device can receive a codec established for the communication session, access a set of codec-specific thresholds stored in memory of the mobile device to determine a handover triggering threshold that is specific to the codec used for the communication session. The mobile device can measure a parameter of a radio signal from the serving AP, and when the measured parameter falls below the codec-specific threshold, a handover procedure can be initiated to transition the communication session to a target AP.

Codec-specific handover thresholds

A codec-specific radio link adaptation procedure can be implemented at the radio access network (RAN) level. A process includes receiving, from a mobile device, a bitstream carrying speech data as part of a communication session, determining, based at least in part on a result of inspecting packets of the bitstream or a notification message from an Internet Protocol (IP) Multimedia Subsystem (IMS) core, that the bitstream is associated with a codec that provides improved performance of the mobile device as compared to legacy codecs in similar radio conditions; and adapting a radio link for the communication session according to the codec.
