SigForge (fully loaded) with GPS/GLONASS/Galileo/Beidou simulator 

Blackcurrant SigForge is an RF Signal Generator capable of generating complex signals and performing Record and Replay allowing engineers to capture real-world electromagnetic signals in the field and reproduce them with high fidelity in a controlled laboratory environment alongside custom generated signals.   

This capability is critical for testing, validating, and debugging complex, dynamic systems without the high cost or unpredictability of live field testing. 

Applications 

  • Receiver Validation: Testing GPS receiver functionality in R&D or production. 

  • Performance Analysis: Measuring accuracy, signal interference, and tracking performance. 

  • Scenario Testing: Emulating complex environments or moving receivers. 

  • Anti-Jamming/Spoofing: Testing receiver resistance to unauthorized signals and Election Warfare systems.

5G/4G Private Cell Simulator

Warehousing, Manufacturing & Industrial IoT (IIoT): Connecting, controlling, and managing industrial machinery, sensors, and robotics to improve efficiency. Providing infil for where public networks have deadspots.

Mining, Utilities and Forestry: Offering coverage in remote and dispersed environments for sensors,  lone worker safety monitoring and communications and tele-operated/remote-controlled equipment. 

Logistics and Ports: Operating secure, high-capacity connectivity for ports, airports, and railway yards, enabling tracking of containers, assets, and supporting communications and security and surveillance appliances even with significant signal shielding 

Key Advantages for all these Use Cases: 

  • Enhanced Security: Data remains local within the private network, reducing exposure to public internet. 

  • Reliability & Performance: Guaranteed bandwidth and lower, consistent latency compared to public networks. 

  • Coverage Customization: Tailored coverage for challenging indoor or remote environments  

Private 5G network vs Wifi: 

Private 5G is used instead of Wi-Fi for industrial, large-scale or mission-critical applications requiring greater reliability, lower latency, and higher device density. It offers a more robust system with better security and broader outdoor coverage.  5G, especially when using low-band frequencies, can provide better signal penetration through walls, metal, and concrete compared to Wi-Fi. A single 5G small cell can cover a much larger area—up to three or four times more indoors and ten times more outdoors—compared to a Wi-Fi access point, requiring less hardware for large venues, warehouses, or factories.  Our private network deployment offers better protection against hacking attempts and unauthorised device access. Wi-Fi is generally a better solution in a less demanding, and often indoor environment 

In addition we can provide 2G in the 1800MHz band which can also support legacy devices.

SPECIFICATIONS: 

Our 5G/4G networks are, by default, compatible with the United Kindgom's OFCOM Shared Access Licence: 

1800 MHz band: 1781.7 to 1785 MHz paired with 1876.7 to 1880 MHz; 

2300 MHz band: 2320 to 2340 MHz and 2390 to 2400 Mhz; 

3800 to 4200 MHz band 

It is not compatible however with the 24.25-27.5 GHz frequency band.

For users with specific needs we can modify the configuration.

4G technical specification: 

LTE Release 8 support with features up to Release 17 

Frequency bands - All FDD and TDD bands in sub-6GHz with support of custom frequencies 

Bandwidth - 1.4, 3, 5, 10, 15 and 20 MHz in LTE (200 KHz for NB-IoT)  

Encryption support: MILENAGE 

Number of active UE  - Scalable -contact us with requirements.  

5G  technical specification: 

3GPP release NR Release 18 

Frequency bands - All FDD and TDD bands in sub-6GHz with support of custom frequencies 

Bandwidth - Up to 100 MHz. 

Please contact us with your requirements (location, required coverage area and number of users) so a Blackcurrant engineer can help you.  For UK customers we can help with gaining the required licence from OFCOM

5G Low (Sub-1GHz) 

n28, n71, n5, n8 

< 1 GHz 

5G Mid (1-6 GHz) 

n77*, n78,* n41, n1, n3 

1 - 6 GHz 

*n77 and n78 only available in benchtop configuration if requested. 

TestNet comes ready configured with 20 test SIM cards.  

Price: from £11,500 GBP /$15,700 USD. (Rental options available). 

Please contact us with your requirements and for a quote. 

SIM cards 

Supports MILENAGE. Can be programmed to your requirements: 

PIN, PUK, ADM K, OPc, KIC, KID and KIK are all supplied and can be programmed to you requirements along with IMSI.  

Compatible with all our 5G/4G networks. Java card based along with the necessary OTA keys to load your own card applets.  

Price: from £6 GBP / $8.25 USD each

Please contact us for a quote and to discuss your requirements.
