Airport 5G & Private Wireless Case Studies ​

Deep-dive reference on specific airport connectivity deployments, CBRS spectrum mechanics, and private 5G hardware platforms relevant to autonomous airside vehicle operations.

1. DFW International Airport -- AT&T / Nokia / Cisco ​

Contract Overview ​

  • Contract value: $10 million
  • Contract duration: 5 years (announced May 2023)
  • Prime contractor: AT&T
  • Equipment vendors: Nokia (CBRS radios), Cisco (WiFi APs)
  • Systems integrator for early PoCs: Betacom (deployed initial CBRS trials); Airspan Open RAN radios also used in the gate A9 baggage trial
  • Network ownership: DFW owns the core network and runs it on-premises inside the airport

Infrastructure ​

ComponentCountDetails
Nokia CBRS transmission sites~33Outdoor and select indoor macro/micro cells covering the 27 sq mi campus
New Cisco WiFi access points~200Added for terminal passenger coverage
Existing WiFi APs upgraded~800Firmware and hardware refresh for faster public WiFi

The airport adopted a converged access architecture: private 5G CBRS traffic and WiFi traffic are routed through a single management platform, giving DFW unified visibility across both networks.

Spectrum ​

  • Band: 3550-3700 MHz CBRS (Band 48)
  • Access tier: General Authorized Access (GAA) -- no PAL licenses purchased
  • SAS coordination: required for all CBSD radios; DFW's deployment registers each of the 33 sites with an FCC-certified SAS administrator

Coverage Design ​

DFW is approximately the size of Manhattan (~27 square miles), with 5 terminals, 7 runways, and 168 gates. The CBRS network provides outdoor campus-wide coverage across the entire airside footprint. Indoor coverage rollout is acknowledged as more challenging due to building penetration losses and the need for field router dongles on older devices.

Applications ​

Currently operational:

  • Monitoring 160+ concessionaires (open/closed status via IoT sensors)
  • Tracking 180 conveyances (escalators, moving walkways) for instant breakdown notification
  • Security cameras in remote outdoor locations connected over CBRS
  • Baggage handling support -- a CBRS network deployed at American Airlines gate A9 for baggage sorting coming off aircraft
  • Cargo asset tracking via private CBRS
  • Digital signage infrastructure
  • ~800-900 iPad users on the private network
  • 40+ outdoor security cameras

In trial / planned:

  • Autonomous shuttles in parking garages (piloted)
  • Autonomous drone operations
  • Vehicle tracking across the ramp
  • Lighting sensors for airside safety
  • Solar-powered LIDAR surveillance
  • Facial recognition cameras
  • Real-time data analytics and digital twin

Measured Performance ​

  • Transaction speeds on the private CBRS network were 50-70% faster than public cellular networks in early commercial pilots
  • PoCs in ramp, cargo, and terminal services demonstrated that CBRS "coverage, throughput, latency and reliability improvements fundamentally improved the efficiency of services such as baggage handling"
  • The CBRS network delivered the low latency and high bandwidth that American Airlines required for the gate A9 baggage sorting trial
  • DFW was able to stand up a proof-of-concept private wireless network within approximately two hours during vendor evaluation

Lessons Learned ​

  1. WiFi alone is insufficient: existing WiFi infrastructure could not provide comprehensive mobile coverage; sensor devices monitoring escalators, parking areas, and restrooms experienced connectivity failures during high-traffic periods
  2. Converged management matters: routing CBRS and WiFi through a single platform reduced operational complexity
  3. Indoor is harder than outdoor: outdoor CBRS rollout was straightforward; indoor deployment required additional planning for building materials and legacy device compatibility
  4. Device compatibility: older devices needed field router dongles to connect to the CBRS network
  5. Airport-owned core is key: DFW owning the core network gave them control over security policy, network slicing, and future vendor flexibility

2. Amsterdam Schiphol Airport -- Ericsson ​

Deployment Overview ​

  • Announced: October 2024
  • Technology partner: Ericsson (Private 5G)
  • Spectrum: Dedicated spectrum allocated by the Netherlands Authority for Consumers and Markets (ACM) -- not CBRS (which is US-only), but a comparable local-license model
  • Network: Ericsson Private 5G with single-server dual-mode core (4G + 5G)
  • Status: Pilot phase, exploring use cases for full deployment

Schiphol is the world's third-busiest airport by international passenger numbers and processes approximately 31,000 pieces of transfer baggage daily.

Spectrum & Regulatory ​

The Netherlands implemented a dedicated spectrum framework allowing enterprises to obtain their own licensed spectrum from ACM. Schiphol secured its own allocation, giving the airport full control over network performance, reliability, and security -- reducing dependency on public or shared networks.

Applications Under Exploration ​

  • IoT-based monitoring of infrastructure and equipment
  • Real-time safety systems
  • Predictive maintenance solutions
  • Support for autonomous ground vehicle operations

Autonomous Vehicle Trials at Schiphol ​

Schiphol is running multiple parallel AV programs, each with different connectivity approaches:

1. reference airside AV stack autonomous baggage/cargo tug (with KLM)

  • Started: August 2024 (Phase 1); February 2025 (Phase 2, pier driving)
  • Function: Autonomous electric baggage tractor with robotic arms for fully autonomous ULD loading/unloading
  • Sensors: LiDAR, 360-degree cameras, 3D cameras for environment mapping
  • Route: From temporary baggage storage to baggage hall; expanding to aircraft stands
  • Connectivity: Not publicly specified whether using the Ericsson private 5G or a separate link; an operator remains present in the vehicle during trials

2. Ohmio Autonomous Buses (with KLM Cityhopper)

  • Function: Shuttling cabin crew from apron to terminal
  • Challenge: GPS unavailable in covered areas; Ohmio developed LiDAR-based positioning as a fallback
  • Connectivity: operational details not disclosed

3. Autonomous Baggage Tractors

  • Testing self-driving baggage tractors on the apron for safety and integration with mixed traffic

Vision ​

Schiphol targets a fully autonomous, emission-free airside vehicle fleet by 2050.

3. Singapore Changi Airport -- Singtel / UISEE ​

5G Aviation Testbed ​

  • Launched: March 2023
  • Duration: 2-year testbed program

  • Location: Terminal 3 airside
  • Planned coverage extension: Singtel gradually extending 5G to public areas in all terminals by end of 2025
  • Telco upgrades: ~4,000 Singtel corporate mobile lines received complimentary 4G-to-5G upgrades
  • Edge computing: Singtel Mobile Edge Computing deployed for on-site processing

Safety Considerations ​

Transmission power and antenna angles are restricted in the airside environment to avoid interference with aircraft systems.

UISEE Autonomous Tractor Fleet ​

UISEE Connectivity Architecture ​

Per UISEE's published solution architecture:

  • Vehicle-to-cloud: 4G/5G network connectivity for reporting vehicle status
  • Road Side Units (RSU): Transmit environmental sensor data to the cloud platform
  • Monitoring center: Connected via WiFi/Ethernet
  • Cloud platform functions: Real-time vehicle state monitoring, remote HD video, exception notification, remote human intervention

Testbed Applications ​

  1. AV tele-operations: Real-time HD video streams with low latency and high transmission stability for remote supervision of autonomous vehicles
  2. Secure flight data transfer: Singapore Airlines transmitting weather and airport data to aircraft via 5G (replacing fiber optic cables)
  3. Remote aircraft inspection (under exploration)
  4. Video analytics / AI for predicting aircraft turnaround times (under exploration)

Latency Context ​

While the specific 10-17ms latency figures referenced in early Nokia/M1 discussions have not been confirmed in public Changi sources, the operational context is:

  • The Singtel 5G testbed is designed for "ultra-low latency" autonomous vehicle teleoperation
  • Industry benchmarks from comparable airport private 5G deployments show:
    • 20 ms average latency for AV operations (UK airport reference deployment)
    • 50+ ms spikes at cell boundaries during handover, reducible to 25 ms with handover threshold optimization
    • Acceptable teleoperation threshold: < 250-300 ms end-to-end
    • Ideal uplink latency for AV teleoperation: 50-120 ms; ideal downlink: 20-80 ms
    • Sub-10 ms latency enables effectively real-time teleoperation

4. LAX -- Lufthansa Cargo / Ericsson Private 5G ​

Deployment Overview ​

  • Location: Lufthansa Cargo warehouse facility at LAX
  • Technology: Ericsson Private 5G
  • Deployment partner: Lufthansa Industry Solutions (IT consulting subsidiary)
  • Spectrum: CBRS (GAA -- free, unlicensed)
  • Timeline: Nearly 1 year PoC, then full deployment

Infrastructure ​

BeforeAfter
17 WiFi access points2 Ericsson 5G radios
Frequent disconnections, manual reauthenticationContinuous coverage, single wide-area cell, zero roaming

The two Ericsson radios provide a single wide-area cellular cell that eliminated roaming altogether -- a critical improvement for mobile warehouse scanners.

Performance Results ​

MetricImprovement
Process speed70-80% faster
Scanning delays97% reduction
Unplanned downtimeEffectively eliminated

Root cause of WiFi problems: When a warehouse scanner lost WiFi connection, the system reset and workers had to log back in manually. A 5-second scanning task would become a 2.5-minute ordeal. With private 5G, reauthentication happens automatically within the core, and the application restarts immediately.

Future Plans ​

Lufthansa Cargo is evaluating broader US rollout at:

  • JFK (New York)
  • ATL (Atlanta)
  • ORD (Chicago)

CBRS spectrum availability makes these expansions cost-effective since no spectrum licensing fees are required.

5. Hamburg -- Lufthansa Technik / Nokia Private 5G ​

Deployment Overview ​

  • Location: Lufthansa Technik MRO facility, Hamburg, Germany
  • Technology: Nokia 5G private wireless (5G Standalone)
  • Frequency band: 3.7-3.8 GHz (German local-license band)
  • Spectrum license: Fixed 10-year license from Germany's Federal Network Agency (BNetzA), obtained late 2021
  • Operational since: 2020 (trial), moved to permanent commercial deployment June 2021
  • Expansion: Extended from one engine overhaul workshop (CFM56, V2500) to a second facility (LEAP, CF6-80 engines) in early 2022

Performance Specifications ​

  • Capacity: > 1 Gbps
  • Latency: < 10 milliseconds
  • Standard: 5G Standalone (SA)

Applications ​

1. Virtual Table Inspection (VTI)

  • High-resolution video streams enable remote examination of engine parts by customers worldwide
  • Fully integrated into AVIATAR Digital Operations Suite (2021)
  • Eliminated need for customers to travel to Hamburg for in-person inspections
  • Became business-critical during COVID when travel was restricted

2. Boroscopy Services

  • Remote digital inspection of hard-to-reach engine cavities
  • Precision measurement capability: can identify scratches as small as 0.3 mm in length
  • Scheduling reduced from weeks-long planning to "very short notice"

Relevance to Airport AV Operations ​

While this is an MRO facility rather than airside AV, it demonstrates:

  • Nokia private 5G achieving sub-10ms latency in an airport-adjacent industrial environment
  • The German local-license spectrum model (3.7-3.8 GHz) as an alternative to CBRS
  • Long-term viability of private 5G with a 10-year spectrum license

7. CBRS Spectrum Technical Reference ​

Band Plan ​

ParameterValue
Frequency range3550-3700 MHz (150 MHz total)
3GPP bandBand 48 (n48 for 5G NR)
Channel bandwidth10 MHz per PAL; GAA can use full 150 MHz
Duplex modeTDD
Max EIRP (GAA outdoor)47 dBm / 30 dBm/10MHz
Max EIRP (GAA indoor)23 dBm

Three-Tier Access Framework ​

Tier 1 -- Incumbent Access

  • Federal users (primarily US Navy radar): highest priority
  • Fixed Satellite Service (FSS) earth stations: 3600-3650 MHz
  • Grandfathered wireless broadband licensees: 3650-3700 MHz (legacy, being phased out)
  • All lower tiers must protect incumbents

Tier 2 -- Priority Access Licenses (PAL)

  • Licensed via competitive auction (Auction 105, July 2020)
  • County-by-county geographic licensing
  • 10 MHz channel blocks within 3550-3650 MHz (up to 7 PALs per county)
  • 10-year renewable license terms
  • Maximum 4 PALs per entity per county
  • Must accept interference from Tier 1; protected from Tier 3

Tier 3 -- General Authorized Access (GAA)

  • License-by-rule: no auction, no license fee
  • Operates across full 3550-3700 MHz band
  • Must not interfere with Tier 1 or Tier 2
  • Must accept interference from both higher tiers
  • Most airport deployments use GAA (DFW, Purdue, LAX Lufthansa Cargo)

Auction 105 Results (PAL Pricing Reference) ​

  • Total raised: $4.58 billion (76 rounds, July 2020)
  • Licenses offered: 22,631 PALs nationwide
  • Average price: $0.217 per MHz-POP
  • High-cost markets: Los Angeles County $0.53/MHz-POP, New York $0.63/MHz-POP, Washington DC $0.85/MHz-POP
  • Minimum bid: $0.02 per MHz-POP ($1,000 minimum per license block)
  • Airport implication: most airports use GAA to avoid these costs; PAL provides interference protection but at significant expense in metro areas

Spectrum Access System (SAS) ​

The SAS is the automated frequency coordinator mandated by the FCC to manage the three-tier framework.

How it works:

  1. Each CBRS Device (CBSD) must register with a certified SAS before transmitting
  2. Registration requires precise latitude, longitude, and antenna height
  3. SAS assigns frequency channels and authorized transmit power levels
  4. SAS continuously monitors for incumbent activity (via Environmental Sensing Capability / ESC sensors) and can dynamically reassign or shut down lower-tier users
  5. All channel assignments are dynamic -- the SAS can change them in real time

FCC-Certified SAS Administrators (as of 2025):

AdministratorStatus
GoogleActive
Federated WirelessActive
SonyActive (formerly Sony's SSP)
AmdocsActive (authorized for commercial operation)
CommScopeWithdrew in 2022; continues to operate ESC network with Google

CPI Requirement: Outdoor CBRS devices (Category B CBSDs) must be installed by a Certified Professional Installer (CPI). Nokia, CommScope, Federated Wireless, and Google are approved CPI Training Program Administrators.

PoC / trial phase3-12 monthsDFW ran 3 PoCs; Lufthansa Cargo tested for nearly a year
CPI installation (outdoor CBSDs)Per-site, included aboveRequires Certified Professional Installer

Key Decision Points for Airport Deployments ​

  1. GAA vs PAL: Most airports choose GAA (free) for initial deployments. PAL provides interference protection but at significant cost in metro markets. DFW, Purdue, and Lufthansa Cargo all used GAA.

  2. Own the core vs managed service: DFW chose to own and run the core on-premises for maximum control. Alternatives include 5G-as-a-Service (5GaaS) models from Betacom and others.

  3. Converged vs separate networks: DFW's converged WiFi + CBRS architecture through a single management platform is emerging as best practice.

  4. Indoor vs outdoor priority: Outdoor airside coverage is straightforward with CBRS macro/micro cells. Indoor terminal coverage is more complex and may still require WiFi overlay.

  5. Autonomous vehicle readiness: For AV teleoperation, target sub-25ms latency with handover optimization at cell boundaries. Private 5G consistently outperforms WiFi for this use case due to deterministic QoS, seamless handover, and no roaming disruption.
