02 · Link chart
Nine communication links
2 Kbps to 200 Mbps
Combined as each project requires. The bandwidth axis is logarithmic.
“—” means no bandwidth figure in the source material. The 7-in-1 gateway is in mass production; NearLink is in production use; the UAV links are delivered; 1.4 GHz at 30 km is under development.
03 · NearLink
Three NearLink technology lines
More than three years of NearLink communication R&D. The audio line builds expertise in data rate and latency; the concurrency line builds expertise in scheduling and stability. Both share one protocol stack and hardware platform.
High-resolution audio
192 kHz / 24-bit
HiFi system: air interface 8 ms, end-to-end < 20 ms, left/right channel offset < 1 ms
Low-latency networking
1:10 · 4 ms
1:1: 3.2 Mbps / 3 ms; used for wireless microphones, in-ear monitors and musical instruments
High-concurrency access
~120 links · ~5,000 devices
Coverage radius ~200 m, up to ~100 Kbps; long standby on coin-cell batteries
04 · In-house protocols and systems
In-house protocols and systems
NTN Reliable Messaging Protocol
In-house messaging protocol for narrowband satellite links: compression, fragmentation, priority, caching and retransmission, de-duplication by sequence number and timestamp.
Multi-link communication hub
The single scheduling point on the aircraft. It decides which link carries the video link, which two links protect telemetry, when to enable dual-5G bonding and when to fall back to satellite.
QoS and AI network prediction
Evaluates the capacity, latency, jitter and packet loss of each link in real time; uses position, flight route and weather to forecast network conditions for the next 10 seconds and switches in advance.
Hyper-converged gateway tunneling and address translation
A private tunnel between the network A and network B boxes; network B servers can use network B or network A IP addresses, and traffic moves to the standby network when the primary fails.
Switch operating system
Built from source on Linux kernel 5.4 or later, with support for domestic Chinese CPUs; MQTT over TLS, bidirectional Layer 3 hardware encryption of forwarded data, chip ID binding.
Cloud AI agent for satellite messaging
Processes narrowband satellite messages and moves rescue workflows forward.
NearLink high-concurrency scheduling
Precise time-slot allocation and on-demand node wake-up, with no channel contention and no wasted retransmissions; frequency hopping and adaptive scheduling in high-interference environments. ~120 concurrent links, ~5,000 devices.
NearLink HiFi audio engine
Dual engines on transmitter and receiver; audio packets carry sequence numbers and timestamps; three-level loss recovery with FEC, PLC and retransmission; left and right channels aligned by timestamp, offset < 1 ms.
05 · Plug-and-play cross-domain, cross-network hyper-convergence
Hyper-Converged Ring Gateway
Ten servers on each of networks A and B joined; when a primary server fails, service traffic moves to the standby network. Contract project.
Specifications
- 10 servers on A and 10 on B joined at the same time
- One A box connects up to 10 A servers
- One B box connects up to 4 A boxes
- Pairings can be added, removed, edited, cleared and switched on or off
