Mga Tampok
-
Full-Duplex / Bidirectional Link

Flexible Frequency Bands
Supports operation on multiple RF bands: ~800 MHz (806-826 MHz), ~1.4 GHz (1428-1448 MHz), and ~2.4 GHz (2402-2482 MHz). This flexibility allows system integration in crowded RF environments, and options to optimize for longer propagation (lower frequency) or higher bandwidth (higher frequency) depending on mission needs. -
Selectable Bandwidth & Modulasyon
Multiple channel bandwidth options are available: 3 MHz, 5 MHz, 10 MHz, at 20 MHz, permitting trade-offs between range, data throughput, and robustness. Modulation schemes include QPSK, 16-QAM, at 64-QAM, automatically adapting to channel conditions. -

Gumamit ng mga kaso & Mga Aplikasyon
This module is highly versatile. Some example applications include:
-
FPV & Live Video Streaming: Real-time transmission of video feeds from UAVs for piloting, cinematography, inspection, atbp. Thanks to high throughput and low latency, usable even under demanding aerial scenarios.
-
Teleoperation / Malayuang Kontrol: Not just video, but two-way data link supports remote flight control, parameter updates, telemetry feedback, atbp.
-
Mesh & Multi-Node Installations: For large areas or swarms of UAVs, ground robots or sensor networks, the mesh networking capability means nodes can relay through each other, extending coverage or providing redundancy.
-
Disaster Response / Paghahanap & Rescue: The capability to transmit over 15-30 km (or further with PA), combined with audio communications, makes this module suitable for scenarios when teams are spread over large distances and need reliable live comms + video.
-
Industrial / Agricultural Monitoring: Long-range monitoring of fields, pipelines, power lines, or remote infrastructure. Real-time video plus sensor data over robust links.
-
Seguridad & Surveillance: Ground based or aerial surveillance systems that demand encryption, robust signal under interference, and flexible deployment of multiple receiver nodes.
Performance & Saklaw ng mga inaasahan
-
Without external power amplification, users can expect reliable LOS ranges up to 15-17 km (air-to-ground). With suitable antennas, line of sight, and favorable conditions.
-
Adding a power amplifier (2W, 5W, 10W) can extend range significantly, depending on antenna gain, terrain, and regulatory limits on radiated power.
-
Signal quality, Bandwidth, and modulation adapt automatically to environmental conditions to maintain link performance; worse conditions reduce modulation order or bandwidth, but preserve the link rather than dropping.
Kumpigurasyon & Kontrolin
-
Web UI: via the Ethernet or IP network, you can access configuration menus: select frequency band, modulasyon, Bandwidth, frame modes, streaming ratios (video/control), encryption settings, atbp.
-
UART / Serial control: For integration with autopilots / flight controllers, remote firmware updates, in-field adjustments of settings.
-
Switch for external PA: Some models include a mechanism for controlling an external power amplifier (on/off), for instance to save power when full power isn’t needed.
Comparisons / Kalamangan
What distinguishes the IS1681 from simpler, one-way video transmitters or basic RC control links:
-
Bidirectional data & video rather than just one-way video/telemetry.
-
Support for full network topologies (mesh, relay networks) rather than simple point-to-point only.
-
Multiple frequency options allow adaptation to regulatory and environmental constraints.
-
Transparent IP networking means it can carry arbitrary IP traffic (hal.g. video, telemetry, kontrolin) rather than being limited to specialized proprietary protocols.
-
Integrated serial/TTL interfaces make it easier to hook up flight controllers, camera, data loggers without needing many converters.

Considerations & Tips
-
Regulatory compliance: When using higher transmit powers or certain frequency bands, ensure that operations are permitted in your area. Licensing, power limits, and band usage differ by country.
-
Antenna setup: To get the advertised range, high-gain antennas, proper mounting (elevated, clear LOS), and matching connectors are essential. Diversity via the auxiliary antenna helps in multipath or blocked signal scenarios.
-
Powering & heat dissipation: Even though module power consumption is modest (~4–5 W), including any PA will add heat. Good airflow / heatsinking is needed especially if enclosed. Use the onboard LED indicators to monitor link quality.
-
Firmware & updates: Keep firmware updated for best performance and bug fixes. Use USB or Web UI as provided.
-
Bandwidth allocation: If using mesh or multiple nodes, bandwidth is shared—so ensure the system design accounts for video + telemetry + control demands, and allocate uplink/downlink ratios as needed.
