Frequency separation between the CBRS client and the CBRS relay under SAS grant.
Oasis Industrial CPE · Version 0.9 Draft
Oasis, in technical detail.
The Oasis is the deployed form of ORB-C1: a client of the site network and a coverage point in its own right, engineered so that a fleet in motion densifies the network wherever the work happens to be.
Architecture
Two roles, one baseband.
Client and access functions share programmable silicon and a single scheduler. That is what makes simultaneous termination and re-emission a design property rather than a workaround.
- The client side takes policy, band selection, and slice assignment from the serving ORB.
- The coverage side is scheduled on the same baseband, so uplink and re-emission never fight for the same slot.
- Session continuity across the TVWS and CBRS transition is make-before-break, so coverage does not blink when the machine moves.
- One firmware tree across the whole radio estate: the same software plane as the ORB, with the same slicing model.
- Where no ORB is present, standalone mode backhauls over LEO, carrier cellular, or a wired handoff on identical hardware.
Uplink
How it reaches the ORB.
Four return paths, selected by policy rather than by hand. The client keeps the best available path and falls back in order as terrain and distance change.
| Path | Band | Propagation character | Where it is used |
|---|---|---|---|
| TVWS-LTE client | 470 to 608 MHz | Non-line-of-sight, into pits and behind structures | Primary uplink where the machine has no clear path to the ORB |
| CBRS NR client | 3550 to 3700 MHz | Near line-of-sight, high capacity | Primary uplink inside the trailer and site zones |
| 5.8 GHz transport | Unlicensed 5 GHz upper | Line-of-sight, aligned | Fixed-Mount units acting as a relay hop or a remote coverage island |
| HaLow return | 902 to 928 MHz | Long range, low rate | Telemetry and management continuity when broadband uplinks are unavailable |
Coverage
What each kit projects.
Coverage geometry is a function of the kit, its mounting height, and the populated radios. Figures are engineering objectives for RFQ response, not guarantees.
| Kit | Emission | Scale | Served population |
|---|---|---|---|
| Machine-Mount | Wi-Fi 7 class, 2.4, 5, 6 GHz | Crew-scale, tens of metres around the machine | Devices, tools, and vision cameras at the point of work |
| Machine-Mount | CBRS relay small cell | Hundreds of metres, terrain dependent | Carrier phone service where the fleet is working |
| Fixed-Mount | Wi-Fi plus HaLow | Office, yard, and long-range sensor tail | Trailer, laydown yard, gate and perimeter cameras |
| Portable | Wi-Fi plus NR+ | Work-cell scale, rapid deploy | Crews working detached from the fleet, inspections, shutdowns |
| All kits | NR+ mesh, 1.9 GHz | Machine-to-machine, mesh-extended across the fleet | Proximity, interlocks, and stop-class signaling |
Deterministic tier
The safety mesh rides with the fleet.
Fleet coordination shares no fate with bulk data. The property is intended to be citable directly in an autonomy safety case.
- NR+ is normative on every unit, so mesh density tracks the fleet and is highest where machines and people interact.
- The 1.9 GHz DECT band is reserved by regulation, so coordination never contends with site data, Wi-Fi, or ISM traffic.
- Machines mesh directly, with no ORB in the loop, and rejoin the site network and the ledger when connectivity returns.
- E-stop class signaling runs on a 1 ms slot structure at URLLC-class latency.
- Saturating the access tiers, or heavy CBRS contention, leaves fleet coordination untouched.
RF engineering
Self-interference is the hard part.
A compact steel-mounted platform carrying a client, a relay cell, Wi-Fi, HaLow, NR+, and a 2.4 GHz multiprotocol radio has to keep every one of them usable at once.
Budget 2
Antenna placement and separation
Antenna placement and separation per the mounting annex for the machine family.
Budget 3
Coordinated scheduling across the
Coordinated scheduling across the coverage stack on the shared baseband.
Budget 4
Relay radiation suspends whenever
Relay radiation suspends whenever geolocation or grant authorization cannot be maintained.
Power and environment
Park mode is a requirement, not a feature.
A parked machine with standby power stays a coverage point at reduced duty, so overnight and shift-change coverage does not collapse with the fleet at rest.
| Kit | Primary power | Requirements |
|---|---|---|
| Machine-Mount | Vehicle 12 and 24 V | Load-dump and transient immunity to heavy-equipment norms, wake-on-ignition, graceful shutdown, optional standby battery for park mode |
| Fixed-Mount | Mains, PoE++, or solar hybrid | PoE budget stated per populated radio set, solar profile shared with the platform specification |
| Portable | Integrated battery | Full-shift runtime at reference duty cycle, hot-swap or vehicle charging |
Annex M
Machine-Mount
Vibration and shock per heavy-equipment norms, ingress and washdown rating, antenna placement per machine family, cable entry and ECM integration, and GNSS 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, grounding and surge protection.
Annex P
Portable
Case drop and ingress rating, rapid-deploy antenna arrangement, and battery transport compliance.
Commissioning and conformance
Installed by the crew that runs it.
Non-specialist installation is held to conformance per kit, and every unit is a full participant in the coordination ledger from the moment it attaches.
- Plug-and-play commissioning by a dealer technician or a superintendent, with no RF specialist on site.
- Kit-specific mechanical install, then power, then automatic attach to the serving ORB and policy download.
- No manual channel planning: band selection, grants, and coverage parameters come from the coordination layer.
- Every attachment, grant event, and position record is written to the ledger through the serving ORB.
- FCC Part 15 Subpart C, for HaLow, 2.4 GHz, and Thread.
- FCC Part 15 Subpart E, for the 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, where populated, the CBRS relay as a CBSD.
- DECT band provisions for the NR+ tier.
- CPE-specific cases: band-transition continuity, relay grant behavior under movement, self-interference limits, park-mode behavior, and non-specialist installation per kit.
