Broadcast Transmission Systems TRIZ Cases

Time-multiplexed sub-frames share a single carrier frequency, reducing receiver power consumption during discontinuous broadcast intervals.

A GaAs FET switch module routes RF signals between antenna and terminals using diplexers to separate frequency bands.

Aggregation server pushes updated email metadata to mobile devices using hash comparison, resolving bandwidth waste from polling.

Modifying OFDM physical layer parameters allows LTE terminals to detect broadcast signals, resolving compatibility issues with mobile radio infrastructure.

Segmenting multicast connection and logical channel IDs resolves resource management complexity while improving data distribution efficiency.

User equipment transmits location data within the RRC connection request message during random access.

Audience response units track transmission delay times to correct measurement errors caused by collision avoidance procedures.

A system caches targeted content on wireless devices based on user profile matching.

Deploying secondary sites in optimized areas enables concurrent frequency reuse without costly coordination studies.

Base stations broadcast signal quality thresholds to estimate subscriber reception levels for adaptive modulation and coding selection.

A physical layer network coding architecture merges separate downlink channels into a single broadcast signal using XOR operations.

Decentralized wireless controllers segment user management to resolve the trade-off between handling large user volumes and maintaining processing efficiency.

Digital baseband transmission over fiber reduces laser jitter and dispersion penalties while increasing reach.
