Rover Field Network Systems

Complete private cellular for campus

Private Cellular

Your own licensed mobile network across a site. Rover designs it, supplies the core and the radios, runs the SIM estate, enrols the devices, and operates the result. Users get coverage that behaves like a carrier network, and you get a network where you decide who attaches and what they reach.

What a complete solution includes

Five parts, one contract

01

Spectrum and core

A 5G standalone core with your own network identity, so devices attach to your network rather than roaming onto whatever is strongest. Spectrum strategy is part of the design, not an assumption left to the customer.

02

Coverage design

A site survey drives radio placement across buildings, yards, and the gaps between them. Disaggregated gNB over the wired backbone for the main footprint, with CPE extensions filling shadowed areas.

03

SIM and identity

SIM-based authentication with the SIM estate managed as an asset: issue, bind, rotate, revoke. A device without an authorised SIM is not a device on the network.

04

Device enrolment

Handsets and endpoints arrive enrolled and configured: private network profile, private APN, roaming and manual carrier selection off, and policy applied before the device reaches a user.

05

Operations

Monitoring, policy changes, and SIM lifecycle handled as a service, reporting into the same plane as Rover routers, switches, and gateways. A NOC staffed 24 × 7 × 365 stands behind it.

Isolation

Keeping devices on your network and off everyone else's

Building a private network is the easy half. The harder question is what stops a device wandering onto a commercial carrier the moment it leaves a good coverage spot. Rover treats that as two tiers of assurance, and is direct about what each one is worth.

Standard isolation

Network
Private MCC/MNC, private APN enforcement, preferred PLMN configuration
Attachment
Roaming disabled, manual carrier selection disabled, carrier profile restrictions
Identity
SIM-based authentication, SIM change detection, SIM allow-listing
Device
Dedicated device mode, application allow-listing, side-loading and developer options disabled
Reach
Always-on VPN, geofencing, remote lock and wipe
Honest limit
Enforcement sits in the operating system and the management layer. The modem still performs the RF scanning any commercial handset performs. This is a hardened commercial deployment, not a restricted radio platform.

Radio-layer isolation

Approach
Moves enforcement out of the operating system and into the carrier and radio layer
Bands
Approved LTE and 5G NR bands only, commercial carrier bands disabled
Databases
Restricted PLMN, roaming, and APN databases in the carrier configuration
Result
Less dependence on management-enforced restrictions, and a smaller attack surface
Availability
Requires OEM and carrier customisation, scoped per programme. Ask before assuming a given handset supports it.

Both tiers block the same outcome, but not at the same place. Tier 1 stops the attachment after the modem has already scanned and found the carrier. Tier 2 removes the bands from the radio, so the path never forms. Deployed together, the earlier gate is the one carrying the assurance.
Most vendors sell the first column and imply the second. The difference matters in an environment where an unauthorised attachment is the thing you are actually defending against, so it is worth asking any supplier which one they are quoting.

Choosing between the two

Private Cellular or RapidSTACK Campus

Private Cellular

Shape
A permanent network for a site, delivered and operated end to end
Pick it when
Private cellular is the point: coverage, device fleet, SIM estate, and isolation policy across a campus
Includes
Survey, core, radios, SIM lifecycle, device enrolment, operations

RapidSTACK Campus

Shape
A kit that extends private 5G across a site alongside Wi-Fi and wired access
Pick it when
You need multi-access connectivity quickly, or the same platform to follow you into a vehicle or the field
Includes
The gateway, radios, and CPE extensions in the RapidSTACK platform

They share a policy plane, so a site can start with one and grow into the other without a rebuild.
