The Problem
For an engineering enterprise, the network isn’t plumbing but the substrate for simulation, cloud engineering, collaboration and AI. Across distributed campuses, demand was outgrowing it. The obvious fix - more fiber, meant trenching, permits and months of lead time; cost that scales with every metre. The client needed fiber-class capacity with wireless agility, delivered as a service on their operator’s licensed spectrum; a platform ready for edge and AI, without owning a network.
Three roles: the operator’s spectrum, Sercomm’s radio, LTTS’ engineering that makes mmWave hold.

Millimeter-wave rivals fiber for capacity. Sercomm’s radios run in the 28 GHz band; the same physics, and the same engineering, applied at 26 GHz (n258) - the mmWave band Indian operators hold:
- Path loss. signal fades far faster than at 01 the sub-6 GHz bands enterprises know.
- Blockage. a wall, a truck, even a person 02 can break a 28 GHz link. It’s line-of-sight.
- Weather. rain and atmospheric absorption 03 add fade that lower bands ignore.
- Penetration. glass and masonry that sub-6 GHz passes through can stop mmWave at the façade.
So you can’t just install a radio. A link that looks fine on a coverage map can drop the moment a van parks in its path. Making 28 GHz hold across a live campus is an RF-engineering problem first, and that’s where this work lived.
The Engineering: Two Disciplines, One System
SERCOMM - The radio layer
AirBroadband is a 5G network-in-a-box: radio access plus an integrated 5G core in one deployable system.
- 28 GHz mmWave small cells; gigabit-class throughput via 4¡Ñ carrier aggregation (up to 100 MHz each).
- Standalone and non-standalone 5G; TR-069/369 management; FCC Part 30 certified (US).
- Indoor, outdoor and CPE units: one platform, whole campus.
LTTS - The system layer, where physics becomes a network
LTTS owned the engineering that turns capable hardware into a dependable network.
- RF design & predictive site survey. modelling propagation, line-of-sight and Fresnel clearance to place radios where the link budget holds.
- Architecture & planning. spending mmWaves capacity where it pays, engineering around its limits, with redundancy where it matters.
- Integration & validation. radio, core, transport and enterprise IT/security as one validated system, proven under real load.
- Operations & monitoring. a visibility layer that keeps the network observable and optimisable after go-live.
- Scalable FWA framework. a design the operator repeats circle by circle: not a one-off link.
THE FEAT
mmWave made dependable. Fiber-class capacity across a distributed campus, no trenching, and links engineered to hold through blockage, weather and load.

What It Unlocks
The real value isn’t the link but the platform it creates. Because the service runs on the operator’s licensed 5G network, one connection can carry what an engineering campus is moving toward next: robotics, AR/VR design review, dense sensors, and AI that processes data on-site in real time; each on its own slice, safely separated. For the operator, that is an FWA line that becomes a managed enterprise service.
And the model travels. The same engineered-mmWave approach works wherever fiber can’t reach: industrial estates, SEZs, older plants, enterprise parks where fiber is slow or uneconomic to trench. A blueprint LTTS and Sercomm can repeat with the operator, circle by circle.
