How POYNTING SWIRL-8 antennas helped connect a new municipal operations

Project Info:

  • Project Partner: ime mobile solutions
  • Client: Eigenbetrieb Stadtentwässerung Homburg (SeH)
  • Location: New operations building, Homburg-Beeden, Germany
  • Challenge: High-bandwidth, resilient internet access before fixed-line connectivity was available
  • POYNTING Solution: Two SWIRL-8 antennas with base enclosures for rooftop router integration
  • Supporting Technology: Four Teltonika 5G routers, four SIMs across two mobile operators, and Bondix cloud bonding

Key Article Takeaways

  • The completed building required immediate connectivity, but no fixed-line installation date was available.
  • Large inspection files, including 4K video footage, required dependable upload and download capacity.
  • Rooftop router integration reduced the planned antenna cabling from sixteen long RF cable runs to two Ethernet cables.
  • Four cellular links were bonded into one logical connection, delivering up to 500 Mbps aggregated bandwidth.
  • The architecture can expand to six WAN links, with DSL and satellite connectivity planned for future integration.

ABOUT IME MOBILE SOLUTIONS

Founded in 1992, ime mobile solutions is a German technology company specialising in wireless connectivity, networking and automation.

With expertise spanning IT and Operational Technology (OT), the company provides connectivity products, software and professional services, helping businesses implement reliable IoT and industrial networking solutions.

As the technical solution specialist, ime mobile solutions was responsible for designing and facilitating the implementation of the connectivity solution, bringing together the relevant technologies to meet the project's specific requirements.

THE CONNECTIVITY CHALLENGE

SeH needed to bring a new municipal operations building online before its fixed-line service was ready. The site was designed for approximately twenty workspaces and regularly transfers large inspection files, including 4K video footage.

A single mobile connection would not provide the resilience required. Network congestion, operator maintenance or a SIM issue could interrupt data transfers and force large uploads to restart.

A SMARTER ROOFTOP INSTALLATION

The original design specified one 4x4 MIMO antenna per router. However, the best rooftop mounting position was more than twenty metres from the distribution point. This would have required sixteen long, ultra-low-loss RF cables, adding cost and installation complexity.

The POYNTING SWIRL-8 offered a more practical approach. Each antenna base enclosure could house two routers directly at the antenna, keeping RF cable paths short and allowing connectivity to travel into the building over standard Ethernet.

THE SOLUTION

Two omnidirectional, cross-polarised SWIRL-8 antennas were installed on the roof. Four Teltonika 5G routers were mounted inside the antenna base enclosures and connected through four SIM cards across two mobile network operators.

Working with ime mobile solutions as the technical solution specialist, the project brought together the antenna, router and bonding technologies required for the site. Bondix Premium Cloud combined the four WAN links into a single logical connection. The complete system was supplied pre-configured, including matched router brackets, power components and mounting hardware, helping simplify installation on site.

SIXTEEN LONG RF CABLE RUNS WERE REDUCED TO TWO ETHERNET CABLES.

RESULTS & BENEFITS

  • Up to 500 Mbps aggregated bandwidth: Four bonded cellular links provide the capacity required for large file transfers and day-to-day operations.
  • Greater network resilience: Two mobile operators and separate radio paths reduce reliance on a single connection.
  • Simplified installation: Rooftop router integration replaces long antenna cable runs with Ethernet connectivity into the building.
  • Ready for future expansion: The bonding platform supports up to six WAN links, enabling planned DSL and satellite links to be added to the same architecture.
  • Pre-configured deployment: Matched components and configuration reduced the need for on-site technical adjustments.

CONCLUSION

The deployment gave SeH a stable, high-capacity connection when fixed-line infrastructure could not meet the project timeline. Designed and facilitated by ime mobile solutions, the implementation combined POYNTING SWIRL-8 antennas with rooftop-mounted routers, multi-operator cellular links and cloud bonding to deliver resilient connectivity while simplifying the physical installation.

The scalable design also provides a clear path towards a hybrid network that can combine cellular, fixed-line and satellite connectivity under one logical connection.
