Aren't the carriers' own coverage maps good enough for this?

No. Published carrier maps are propagation models averaged over large areas and biased toward showing coverage. They do not capture in-motion handover gaps, localized dead zones at underpasses and depots, or how a network behaves under load. For a safety-relevant decision you need measured ground truth on the exact routes you will drive, on every carrier — which is what a route survey provides.

Do you measure all carriers, or just one?

All major carriers at once. The gaps that matter are carrier-specific — a segment that is solid on one network can be a dead zone on another — so we capture every carrier simultaneously. That is exactly the data you need to choose a primary carrier and design multi-carrier failover that covers each network's holes.

Can we re-run the survey ourselves as routes change?

Yes. Surveys are captured with the Cell Surveys app, so the same route can be re-driven and re-measured whenever your network or service area changes — when a carrier re-farms spectrum, when a site goes down, or when you expand the ODD. Coverage is not static, and the survey does not have to be either.

Do you survey highway corridors for autonomous trucking, not just city service areas?

Yes. Long-haul driverless corridors run through exactly the sparse, rural terrain where coverage is thinnest and most consequential. We survey full corridors end to end and flag the rural gaps, terrain shadows, and single-carrier stretches that matter most for trucking deployments.

Autonomous Vehicle Coverage Surveys

Route-based RF measurements for robotaxis, driverless trucks, and AV fleets — the empirical coverage data behind reliable teleoperation, remote assistance, and connected operation along every mile of the operational design domain.

An autonomous vehicle is only as reliable as the network behind it. Robotaxis lean on cellular links for remote assistance and teleoperation, driverless trucks stream telemetry and sensor data back to operations centers, and every vehicle depends on connectivity for over-the-air updates and fleet coordination. A single dead zone that is a minor annoyance for a phone user becomes an operational and safety problem when a vehicle needs a remote operator and cannot reach one. National carrier coverage maps are modeled, averaged, and far too coarse to trust for this. A route-based signal survey drives the actual operational design domain and produces the ground-truth coverage record that AV operators, teleoperation vendors, and fleet integrators need before they deploy.

RF Challenges in This Environment

The specific physical and operational conditions that make reliable cellular coverage hard in this kind of environment.

Rural and highway dead zones

Long stretches of interstate, agricultural, and remote terrain have sparse tower density and genuine no-coverage gaps that no single carrier fills. Driverless trucking corridors run straight through them.

Coverage handoff while in motion

A vehicle at speed hands between towers and bands continuously. Brief gaps, failed handovers, and latency spikes at cell edges can interrupt a teleoperation session at exactly the wrong moment — continuous coverage matters as much as peak signal.

Urban canyons, tunnels, and structures

Dense downtown cores, tunnels, underpasses, parking structures, and depots create sharp, localized dead zones inside an otherwise well-covered service area — the block-by-block spots where a robotaxi can suddenly lose its link.

Single-carrier exposure

A vehicle on one network is at the mercy of that carrier's footprint. Coverage that looks fine on one carrier can be a dead zone on another, so the gaps that matter are carrier-specific and only visible by measuring every network at once.

Capacity under load

Coverage can be present yet unusable when the network is congested — a stadium letting out, a downtown at rush hour, or an outage that floods the cell. Teleoperation needs sustained uplink bandwidth, not just a bar of signal.

Why a Signal Survey Matters Here

For an AV operator, a coverage gap is not a dropped call — it is a vehicle that may not reach the human prepared to help it. Regulators reviewing deployment permits and internal safety cases increasingly expect operators to demonstrate reliable wide-area connectivity, and teleoperation has hard requirements: sustained uplink bandwidth for live video and end-to-end latency low enough to act on, held continuously while the vehicle is moving. A route survey turns 'coverage should be fine here' into a measured, carrier-by-carrier record of exactly where along the ODD the link weakens, drops, or congests — the evidence to choose carriers, plan failover, bound or geofence the operating area, and document connectivity for a safety case.

How We Survey This Environment

Methodology tailored to the realities of this environment.

Drive the operational design domain end to end — every route, corridor, and service-area street the fleet will run — capturing coverage continuously with the vehicle in motion at operational speeds.
Carrier-by-carrier capture of RSRP, RSRQ, SINR, RSSI, PCI, and serving band and technology for every major network simultaneously, so single-carrier gaps and multi-carrier failover gaps are both visible.
Targeted measurement of the hard spots — tunnels, underpasses, parking structures, depots and yards, bridge approaches, and known rural gaps — where the link is most likely to fail.
GPS-tagged, time-stamped logging through the Cell Surveys app, so every sample maps to a precise location and the same route can be re-surveyed as networks and routes change.
Deliverables include route coverage maps, a ranked list of dead zones and weak-link segments by location and carrier, and an interactive dashboard for operations, connectivity, and safety teams.

Common Use Cases

Pre-deployment ODD validation

Survey a route or service area before going driverless to confirm the connectivity the operation assumes actually exists, and bound the operational design domain to where it does.

Teleoperation & remote-assistance risk mapping

Pinpoint the segments where a remote operator could be unreachable, so handoffs, pull-over zones, and fallback behavior can be planned around the real gaps instead of assumptions.

Carrier selection & multi-carrier failover

Compare networks segment by segment to choose the primary carrier and design failover that covers the other carriers' dead zones.

Route monitoring over time

Re-survey routes on a schedule to catch coverage that degrades as carriers re-farm spectrum or decommission sites, and as the fleet expands into new areas.

Compliance & Regulatory Notes

Autonomous-vehicle operators are increasingly expected — by regulators reviewing deployment permits and by their own functional-safety processes — to show that the connectivity their remote-assistance and teleoperation systems rely on is genuinely available across the operating area. A documented, carrier-by-carrier route survey provides defensible evidence of where coverage meets the bandwidth and latency the operation requires and where it does not, supporting ODD definition, safety-case documentation, and operational risk decisions. We measure and document; we do not sell or install cellular hardware or connectivity.
