Services
From a single test cell to a working network with voice, we take on the radio, the core and everything that connects them.
RAN and radio
The radio access network is where most of the hard problems live: frequencies, timing, interference and coverage. We plan it, build it and measure it.
- LTE and 5G NR cell design and configuration (FDD and TDD bands)
- Coverage prediction with NVIDIA Sionna ray tracing
- Software-defined radio builds with LimeSDR and USRP-class hardware
- Frequency and timing calibration against reference networks
- Handover and mobility tuning between cells
- Coverage, throughput and uplink quality testing
- 5G non-standalone (EN-DC) anchor and NR cell set-up
Core network and voice
A cell is only useful with a core behind it. We deploy and run the 4G/5G core, the subscriber side and the services phones actually use.
- 4G EPC and 5G core deployment and integration
- SIM programming and subscriber provisioning
- IMS and VoLTE set-up
- SIP voice, video and messaging, including our own CelTech Call apps
- Network isolation and security between devices, LAN and internet
- Monitoring dashboards for cells, phones and traffic
Consulting and training
Whether you are deciding if a private network makes sense or want your own team to run one, we explain it plainly and show it working.
- Feasibility studies and network design reviews
- Proof-of-concept builds on real radios and real phones
- Hands-on workshops on RAN, 4G and 5G
- Help choosing hardware, software and frequencies
- Troubleshooting existing deployments
