Abstract: A method for receiving data on a mobile device includes accessing information identifying a number of collaborator devices and receiving respective portions of the data from each of the number of collaborator devices. The respective portions depend on at least one of (a) throughputs between the mobile device and the number of collaborator devices and (b) potential debits charged by the number of collaborator devices. The receiving occurs via mobile-to-mobile connections between the mobile device and the number of collaborator devices. The received respective portions of data are stored at the mobile device. Content is generated on a display of the mobile device based on the stored respective portions of the data.

Abstract: Disclosed herein are techniques for collecting information related to a crime or distress scene. An indication is received that a phone (“distressed phone”) has declared an emergency or distress event and a location of the distressed phone is also received. An additional set of phones, and their associated geographic locations, in vicinity of the distressed phone at a time that the distressed phone declared the emergency or distress event is determined. For each of the additional set of phones and the distressed phone, a number of cameras capable of tracking that phone is determined. For a phone from the additional set of phones and the distressed phone, video or image data related to a user of the phone is captured using at least one of the determined number of cameras capable of tracking that phone.

Abstract: Disclosed herein are techniques for determining a vehicle-based reputation. A driver of a remote vehicle is identified at a navigation system. Driving of the driver is characterized based on the occurrence of one or more events. Transmission of the characterization is caused to a remote server. Also disclosed herein are techniques for determining a vehicle condition. A remote vehicle is identified at a navigation system. A condition of the remote vehicle is characterized based on the occurrence of one or more events. A transmission of the characterization is caused to a remote server.

Abstract: A method and an apparatus for recording information is disclosed. A user is identified based on a user ID. The user is tracked based on the user ID and a determined present location. User metadata is tagged at the identified present location. User presence at the present location is recorded.

Abstract: Disclosed herein are techniques for granting access to a mobile device on a network. An access request is received from the mobile device. A communication score, a content score, and a reputation score associated with the mobile device is determined. An access policy for the mobile device on the network is set based on at least one of the communications score, the content score, and the reputation score.

Abstract: A system including a processor; a memory configured to store information on a pool of virtual subscriber identification modules (SIMs), each of the virtual SIMs having an associated International Mobile Subscriber Identity (IMSI); and a transmitter configured to provide a mobile device with a virtual SIM from the pool of virtual SIMs on an as-needed basis to ensure connectivity. The pool of virtual SIMs includes SIMS for one or more regions based at least in part on a subscriber base. A method includes transmitting a request to a server, receiving a virtual SIM in response to the request; and generating instructions to configure at least one communications parameter of a mobile device based on the received virtual subscriber identification module (SIM).

Abstract: The optimal allocation of resources—power and bandwidth—between training and data transmissions is considered for time-selective Rayleigh flat-fading channels under the cutoff rate criterion. The transmitter, assumed to have statistical channel state information (CSI) in the form of the channel Doppler spectrum, embeds known pilots symbols into the transmission stream. At the receiver, instantaneous, though imperfect, CSI is acquired through minimum mean square estimation of the channel based on some subset of pilot observations. The cutoff rate is computed and the optimal resource allocation is developed using, for example, a Gauss-Markov correlation model of a communication channel or a Jakes model.

Abstract: A cutoff rate may be used to determine an optimal binary input distribution for a communications system which operates with imperfect receiver channel state information (CSI) at the receiver. First, the cutoff rate may be evaluated and used to analyze the optimal binary input as a function of CSI quality and receiver Signal to Noise Ratio (SNR). Next, limiting distributions of BPSK and On-Off Keying (OOK) may be examined and an analytic design rule for adaptive modulation between these two inputs (as the receiver CSI changes) may be derived. The modulation scheme may provide near optimal performance by employing only these limiting distributions rather than the full spectrum of binary inputs. Finally, the results may be used to design an adaptive modulation scheme for Pilot Symbol Assisted Modulation (PSAM) systems.
