Frequently Asked Questions
What is the difference between the AT-T, AT-M and AT-S link series?
All three run on 1.4 GHz with real-time spectrum sensing and frequency hopping. The T series is anti-interference point-to-point, up to 300 km at 20 Mbps. The M series adds MESH networking to 128 nodes at 40 Mbps. The S series trades bandwidth for reach: 5 Mbps up to 500 km.
What is the operating frequency band of the AEROLINK links?
All AEROLINK series operate on 1.4 GHz and support custom frequency bands. Transmit power ranges from 0-27 dBm on the compact AT-T27 up to 0-46 dBm (dual 40 W) on the AT-T46, AT-M46 and AT-S46, which dissipate 172 W at full output.
Do your radio links meet local frequency regulations?
The AEROLINK links run on 1.4 GHz and support custom bands, but the operating frequency, bandwidth and transmit power must comply with local radio regulations and the necessary licences must be obtained by the operator. Licensing, frequency configuration and regional suitability remain subject to contract and technical confirmation.
What does Aerosys Technology supply?
Our catalogue covers 279 product models across 13 categories. Behind that catalogue sits production in the Pearl River Delta and a commercial centre in Hong Kong that handles the contracting, freight, banking and export documentation cross-border trade depends on.
What is the minimum order quantity?
It depends on the product line. Ground control stations are quoted on a 5-unit basis, while video and data links and camera payloads are quoted from a single unit. Complete platforms such as VTOL aircraft, multi-rotors and unmanned ground vehicles are quoted per set. Where a product page states a different MOQ, that page governs.
How do I get a quotation, and how long is it valid?
Send us the model numbers and quantities you need by email. Quotations are issued in USD and are valid for 14 days from the date of issue unless a different period is stated. An order is confirmed only when we issue a written order confirmation and receive the agreed payment; a quotation or an email alone is not an accepted order.
