OSI-ORB-C1 · Version 0.9 Draft

ORB-C1, the industrial CPE.

One device, three mounting kits, every machine a site node. Each unit is simultaneously a client of an ORB and a coverage point for the devices and people around it, so a deployed fleet densifies the network wherever it operates.

Section 1

Kits, not variants.

Electrical architecture, radio complement, software plane, and conformance are identical across all three deployment forms.

Machine-Mount Kit

On the equipment

Vehicle power, ECM and telematics integration, and vibration-rated mechanics. The recommended configuration is Class A wherever vision workloads are present.

Fixed-Mount Kit

Pole, trailer, container

Mains or PoE power, with alignment provisions for units backhauling over the 5.8 GHz transport tier. This is the smart job trailer configuration.

Portable Kit

Crew case

An integrated battery with full-shift runtime, a rapid-deploy antenna arrangement, and drop and ingress rating for the case.

Sections 1 and 2.1

Shared silicon, both ends of the link.

The CPE cellular client runs on the same programmable baseband family as the ORB cellular complex: a TVWS-LTE client at 470 to 608 MHz and a CBRS NR client at 3550 to 3700 MHz, 2x2 MIMO minimum, 256-QAM, with full TDD frame flexibility. Band selection and steering follow policy from the serving ORB.

  • Uplink-heavy TDD frames honored end to end.
  • Session continuity across the TVWS and CBRS band transition, make-before-break.
  • Coordinated deterministic scheduling on the shared baseband.
  • One firmware tree across the entire radio estate of a site.

Section 2.2

The coverage stack.

Five functions define what the CPE emits. Three are normative on every unit; two are standard populates.

ORB-C1 coverage stack
FunctionRadioStatusRole at the point of work
Passpoint Wi-Fi APWi-Fi 5 and 6 GHz, Wi-Fi 7 class, plus 2.4 GHzNormativeStaff and device Wi-Fi, OpenRoaming carrier offload, camera and tool connectivity

Thread border router and BLE meshIEEE 802.15.4 and BLE multiprotocol, 2.4 GHzNormativeMatter periphery, worker tags, asset beacons, headsets, sensor commissioning

NR+ on every CPE is deliberate: mesh density tracks the fleet, so the deterministic safety fabric is densest exactly where machines and people interact, and self-heals around the fleet as it moves.

Section 2.3

The NR+ C2 profile.

NR+ nodes mesh directly machine to machine, with no ORB in the loop, forming the fleet command-and-control layer. Fleet C2 shares no fate with bulk data, a property intended to be citable directly in autonomy safety cases.

  • Work-zone deconfliction, and haul-road intersection negotiation between machines.
  • Proximity interlocks between machines, and between machines and personnel.
  • E-stop class signal propagation at URLLC-class latency on a 1 ms slot structure.
  • Reserved spectrum: the 1.9 GHz DECT band is allocated to DECT technology exclusively, so C2 never competes with Wi-Fi, ISM, or site data.
  • Frequency-gap immunity: saturating the 2.4 or 5 GHz access tiers, or heavy CBRS contention, leaves fleet coordination untouched.
  • The mesh operates whether or not a serving ORB is reachable, and rejoins the site network and the ledger when connectivity returns.

Sections 2.4 and 2.5

The person scale, and the moving radiator.

Two subsystems where the CPE does something a fixed base station cannot.

Section 2.4

BLE and Thread from one radio

Concurrent-multiprotocol silicon provides BLE and BLE Mesh from the same radio and antenna as Thread, at no extra hardware cost. BLE senses at the person and asset scale, NR+ acts at the machine scale, and the CPE translates person-presence into the C2 fabric where policy requires it.

Section 2.5

Relay grants under motion

The relay's SAS grant is bound to geolocation, so the unit maintains continuous position integrity, requests grant updates on movement per SAS policy, suspends radiation when authorization cannot be maintained, and writes every grant event to the ledger exactly as an ORB does.

Section 2.5

Self-interference budget

Isolation between the CBRS client and the CBRS relay, and across the whole coverage stack on a compact steel-mounted platform, is a first-order requirement: frequency separation under SAS grant, antenna isolation per the mounting annexes, and coordinated scheduling on the shared baseband.

Section 4

Edge compute classes

Class A carries local compute and storage for on-device vision analytics and capture buffering. Class B omits the tier with identical software interfaces, so policies remain portable across a mixed fleet.

Section 3

Named use classes.

Four deployment patterns the specification names and holds to conformance.

Vision

Camera and vision termination

Each class on its right radio: high-bandwidth vision on Wi-Fi terminating in local compute, long-range site cameras on HaLow, commodity fixed cameras on Matter over Thread or Wi-Fi, and safety-loop detection on the NR+ tier. Analytics run at the edge, so the WAN carries events and clips rather than streams.

People

Staff connectivity and reachability

Passpoint on every unit, plus the CBRS relay where populated, means workers near equipment have device connectivity and carrier service at the point of work. Every machine becomes an emergency communications asset.

Machines

Machine data

The Machine-Mount Kit integrates with the vehicle ECM and telematics bus, carrying grade control, telemetry, and autonomy-class traffic on QoS flows, with the deterministic tier available for control-loop and safety signaling.

Trailers

Smart job trailer, with standalone mode

A Fixed-Mount unit serves Wi-Fi through the office and laydown yard, manages locks, HVAC, power monitoring, and cameras over Matter and Thread, and tracks assets over BLE. Standalone mode is normative: with no ORB present it backhauls over LEO, carrier cellular, or wired handoff, on identical hardware.

Sections 5 and 6

Power classes and mounting annexes.

Park-mode behavior is a named requirement for the Machine-Mount Kit: a parked machine with standby power remains a coverage point at reduced duty, so overnight and shift-change coverage does not collapse with the fleet at rest.

ORB-C1 power classes

Machine-MountVehicle 12 and 24 V systemsLoad-dump and transient immunity to heavy-equipment standards, graceful shutdown and wake-on-ignition, optional standby battery for park-mode coverage

Annex M

Machine-Mount

Vibration and shock per heavy-equipment norms, ingress and washdown rating, antenna placement per machine family with the coverage-stack isolation budget on a steel platform, cable entry and ECM integration, and GNSS antenna position for relay-grade location integrity.

Annex F

Fixed-Mount

Pole, trailer, and container brackets, alignment provisions for units backhauling over the 5.8 GHz transport tier, and grounding and surge protection.

Annex P

Portable

Case drop and ingress rating, rapid-deploy antenna arrangement, and battery transport compliance.

Sections 7 to 9

Software plane and conformance.

The CPE runs the same OpenWrt-based software plane as the ORB, receives policy from its serving ORB, and participates fully in the slicing model. Every unit is a ledger participant: client attachments, coverage-stack attachments, relay grants, and position records are all written through the serving ORB's coordination layer.

  • FCC Part 15 Subpart C, for HaLow, 2.4 GHz, and Thread.
  • FCC Part 15 Subpart E, for the Wi-Fi 5 and 6 GHz client and AP functions.
  • FCC Part 15 Subpart H, for the TVWS client.
  • FCC Part 96, for the CBRS client, and the CBRS relay as a CBSD where populated, plus DECT band provisions for NR+.
  • CPE-specific cases: session continuity across the band transition, relay grant behavior under movement including suspension on lost authorization, self-interference limits per Annex M, park-mode behavior, and non-specialist installation per kit.

The fleet is the network.

ORB-C1 v0.9 is available for partner and engineering review, along with the mounting annexes.
