Outdoor fibre is typically laid between buildings within an SAF camp or base to enable data network connectivity. Besides being expensive, such fibre infrastructure can take a long time to deploy especially when there are ground issues like limited road access. To overcome these challenges, DSTA overlaid a wireless mesh network across the buildings for inter-building network connectivity.

Besides eliminating expensive outdoor fibre infrastructure, the mesh network enhances the camp network resiliency with its self-forming and self-healing properties that will automatically reroute and reconnect to other peer nodes in the event of any node failure. Without this wireless mesh network, the DSTA team would need to lay a redundant set of fibre infrastructure to achieve the same level of resiliency.

Optimisation of the outdoor wireless mesh network infrastructure is also performed by leveraging less costly indoor antennae instead of outdoor antennae. The team has innovatively customised and extended indoor antenna cable for greater reach. Besides reducing cost, it simplified installation and reduced the deployment period.

This wireless mesh technology enables the data network in camps to adapt effortlessly to various camp redevelopment initiatives. This is especially useful when the camp faces ground constraints to build wired network infrastructure. The technology also presents the SAF with greater agility in responding to diverse operational scenarios where rapid deployment across large geographical coverage is required.
