Frequently asked questions about LongWave Wireless

What is the minimum order quantity?

One unit. Average lead time is about one month in both peak and off-peak season (TÜV Rheinland, MIC-ASR267293, 30 June 2026).

How large is the factory?

11,000 m² in Fuzhou, Fujian, with three assembly lines and one aging room (TÜV Rheinland, June 2026).

How many people work there and how many in R&D?

66 at the time of the audit, 33 of them in R&D — 50% of headcount (TÜV Rheinland, June 2026). The 2026 company profile states 98 employees company-wide.

Which port do you ship from?

Xiamen Port, on FOB or CIF terms; payment by LC or T/T (TÜV Rheinland, June 2026).

Do you do ODM and OEM?

Yes to both. Own tooling, SDK available, and four customisation levels: sample, drawing, partial, and full custom (TÜV Rheinland, June 2026).

What test equipment do you have?

48 spectrum analyzers, 48 network analyzers and 48 oscilloscopes — 144 instruments in total (TÜV Rheinland, June 2026).

How is quality controlled?

Four QA/QC staff perform 100% finished-goods inspection, covering appearance and function, with documented traceability, non-conforming-goods and corrective-action procedures (TÜV Rheinland, June 2026).

Which certifications do you hold?

ISO 9001:2015, ISO 14001, ISO 45001:2018, CE, RoHS and SRRC; also a National High-tech Enterprise certificate (TÜV Rheinland, June 2026). SGS verification relates to 2025 and is cited with its year.

How many patents do you have?

21 patent applications filed as of October 2026, of which 6 are granted (1 invention patent and 5 utility models). Five were granted at the time of the TÜV audit on 30 June 2026.

Can I visit the factory?

Yes. Audits and factory visits are arranged through the sales contact published on this site.

What is your export experience?

We began exporting in 2025. Our export share is below 10% of revenue, and the main market is domestic (TÜV Rheinland, June 2026).

What does the TÜV audit actually verify?

It verifies that the company exists and is registered, that it has real R&D and manufacturing capability, that its quality management system is effective, and that it holds a valid import/export licence. It is not a product-legality determination and not an export authorisation.

These answers are drawn from the TÜV Rheinland audited supplier report MIC-ASR267293 (30 June 2026).

How IMSI Catchers Work — The Technology Behind Long Wave Wireless Systems

SDR Architecture, Non-Polling Multi-Carrier Design, RSRP Precision Positioning, and 5G NR Support Explained
What Is an IMSI Catcher?
An IMSI (International Mobile Subscriber Identity) catcher — also known as a cell site simulator, false base station, or StingRay — is a device that mimics a legitimate cellular tower, compelling nearby mobile devices to connect to it. Once connected, the device can extract the device's IMSI/IMEI identifiers and, in advanced systems, determine the device's precise location.
Long Wave's Core Technology Stack
  1. Software-Defined Radio (SDR) Platform
All Long Wave products are built on a self-developed SDR platform, enabling:
  • Flexible frequency band configuration across 2G/3G/4G/5G
  • Software-upgradable protocol stacks (no hardware changes needed for band additions)
  • Real-time signal processing and analysis
  • Remote configuration and firmware updates
  1. Non-Polling Multi-Carrier Architecture
Unlike many competing systems that use round-robin polling (sequentially scanning carriers, causing blind spots), Long Wave's architecture supports true concurrent carrier operation:
  • RW-IMSI-V01: 24 carriers simultaneously
  • Portable/Drone units: 14 carriers simultaneously
  • This means all frequency bands are monitored in real time with no gaps
  1. RSRP Precision Positioning
Long Wave's proprietary positioning algorithm uses RSRP (Reference Signal Received Power) measurements from built-in high-gain directional antennas to achieve:
  • <0.5 meter accuracy on vehicle and backpack units (industry average: 2-5 meters)
  • 11dBi directional antenna with 35-degree beam width on the RW-IMSI-P03
  • Cross-floor detection capability up to 15 floors
  • Report value efficiency: >=98%
  1. 5G NR Full Support
All Long Wave products support 5G NR in both SA (Standalone) and NSA (Non-Standalone) modes across these bands:
N1, N2, N3, N5, N7, N8, N20, N26, N28, N38, N40, N41, N66, N77, N78, N79
This is significant because many competing IMSI catcher products — including legacy Western systems — only support up to 4G LTE.
  1. GPS + BeiDou Dual Synchronization
Long Wave is one of the few IMSI catcher manufacturers to support both GPS and BeiDou satellite synchronization, critical for operations in regions where one system may be unavailable.
  1. Active Interception with A5 Decryption
The RW-IMSI-P02 actively intercepts voice calls and SMS messages, supporting real-time decryption of:
  • A5/1 (commonly used in 2G GSM)
  • A5/2 (weaker export-grade encryption)
  • A5/3 (stronger cipher, used in 3G/4G)
