## Summary
The MeshLive project, developed by [Gautam], implements a fully decentralized mesh network for voice and video telephony using only standard Android smartphones and their built-in Bluetooth radios. Unlike typical mesh communication tools that require dedicated hardware like LoRa modules, MeshLive operates entirely as an Android application, forwarding encrypted traffic between devices within approximately 20-meter range. The system supports end-to-end encrypted voice calls, one-way video broadcasting, and experimental two-way video calling, with each user identified by a scannable unique identifier rather than a persistent public identity.

Privacy features include automatically rotating random display names every 15 minutes for non-contacts, preventing passive identification of users in proximity. The mesh architecture allows each phone to relay signals to extend network reach, though practical range remains constrained by standard Bluetooth hardware limitations. The project represents a software-only approach to infrastructure-independent communication, contrasting with hardware-dependent alternatives in the mesh networking space.

## Mesh architecture and privacy design
- **Bluetooth-only implementation:** MeshLive requires no dedicated radio hardware, using standard smartphone Bluetooth with approximately 20-meter per-hop range and multi-hop relay through participating devices.
- **End-to-end encryption:** Both voice and video traffic receive end-to-end encryption, though the specific cryptographic protocol is not detailed in the source.
- **Identity and contact model:** Users possess unique scannable identifiers for contact creation, while non-contacts see only automatically rotating random names refreshed every 15 minutes.
- **Video capabilities:** One-way video broadcasting is more tested than two-way video calling, which remains experimental in the current implementation.
- **Range extension limitations:** The source notes that directional antennas can extend Bluetooth range significantly, but expects typical users to rely on unmodified smartphone hardware.

## Why it matters
MeshLive lowers the barrier to entry for decentralized communication by eliminating hardware requirements, making it accessible to any Android user for emergency preparedness, events, or regions with unreliable infrastructure. For the open-source ecosystem, it demonstrates that mesh networking applications can achieve practical voice and video functionality on commodity hardware, potentially inspiring integration with existing secure messaging platforms or disaster-response tools. The project's software-only approach contrasts with the hardware-centric norms of the mesh networking community, which typically depends on LoRa or specialized radios for comparable functionality.
