Extending the reach of wireless

Facilities such as  oil rigs, mining operations and education and healthcare establishments in remote locations have distinct communications requirements even if they are located at great distances from existing network infrastructure.

Quortus technology allows functions normally performed in the core network to be moved out to these remote locations, close to the user. This in turn allows service offerings that combine robust and secure on-site voice and data communications; corporate communications “back to base” or other remote locations; and morale communications home.

Just as importantly, the service operator – which may or may not be a traditional network operator – can offer ease of use features such as own-number call termination, allowing users to “bring their own” device or SIM.

The flexibility enabled by Quortus supports a variety of technical implementation paradigms. For example, the service could be run by or on behalf of a mobile network operator in a RAN extension model, connecting back into the centralized core and with local breakout for both voice and data to enable locally hosted services.

Another option is to run the system as a full roaming network, with its own core network on-site, or with MAP/Diameter aggregation hosted centrally. Alternatively the network can be run as a completely private network: although this requires SIM-swapping or dedicated devices.

Finally, there is the option of a hybrid offering, with DECT-style private network devices running in parallel with BYOD for morale communications.

Backhaul is, of course, a significant issue for such remote networks, and we provide a full range of optimization technologies to improve QoS and reduce costs, based on the ability to locally offload raw packet data, backhaul that data in an optimal fashion, and then re-tunnel it to ensure continuity of GGSN-base billing, walled-garden APN services and support of any legal intercept obligations.

Use case example: full roaming network for an oil rig

A local Virtual Mobile Core combines with small cells to give users access to the full range of voice, SMS and data services, with local traffic offload and full PBX integration. Backhauled via satellite and offered in partnership with an MNO/MVNO which handles authentication and roaming interconnect, this style of service allows users to bring their own device and SIM.
