Absolute Validation

Absolute Validation is an independent, United Kingdom-based telecoms test house providing technical validation expertise across mobile networks, connected devices, and telecommunications services. The laboratory serves a broad client base of original equipment manufacturers (OEMs), mobile network operators (MNOs), and telecoms equipment vendors who require rigorous, third-party testing evidence to support engineering decisions, operator acceptance, and global device certification. With director and management teams carrying decades of R&D project experience across the complete product lifecycle — from early prototype hardware through commercial launch and into market maturity — Absolute Validation brings deep domain knowledge to every engagement.

The company's service portfolio spans the full device and network test lifecycle. Core disciplines include GCF Field Trial (FT) certification, operator acceptance testing (OAT), field testing as a service, project validation, regression testing, error verification and defect management, and user experience (UX) and user interface (UI) testing. Complementing these are structured technical reporting and dashboards designed for both engineering review and customer-facing deliverables. Every engagement is oriented around repeatable, evidence-based testing that produces actionable outputs rather than raw data, with a deliberate focus on useful engineering evidence over noise.

Absolute Validation has been an active Global Certification Forum (GCF) member since 2012 and holds two distinct GCF designations: Recognised Test Organisation (RTO) and Assessment Capable Entity (ACE). As a GCF RTO, the laboratory is qualified to execute Field Trial testing as part of the formal GCF device certification process. Their accredited GCF scope covers Annex F5.1 (5G Standalone (SA), 5G Non-Standalone (NSA), EUTRAN, UTRAN, GERAN, SMS, SIM, and TS.42), Annex F5.2 (IMS services including Voice over LTE (VoLTE), Voice over WiFi (VoWiFi), and Voice over New Radio (VoNR)), and Annex F5.4 (Massive IoT, specifically CAT-M1 and NB-IoT). As a GCF ACE, Absolute Validation assists OEMs and device manufacturers in identifying the exact conformance, field test, and interoperability tests required for GCF certification, then independently reviews completed test results to confirm that each product satisfies all applicable GCF certification criteria.

Operator acceptance testing is a major service area, supporting OEMs and MNOs in benchmarking devices against industry standards or competing products ahead of ranging and commercial sale decisions. Testing scenarios cover voice quality and data throughput performance, call stability, and battery life assessments, conducted in both controlled static laboratory environments and live mobile network conditions. Project validation services extend this work into the broader OEM product development lifecycle, managing user-focused trials in business-critical markets and regions globally to surface defects before commercial release. The laboratory also maintains in-house capability for fully automated testing, providing high-throughput capacity that supplements its skilled human test teams.

Field testing is delivered through a fully scalable Field Trials Team with permanent local test resources in five major European countries, supplemented by strategic associates in North and South America, China, and India. This distributed geographic footprint enables fast, cost-effective testing deployments with local language support across diverse live network environments. Absolute Validation manages all project planning and logistics — from drive testing, walk testing, and venue-based assessments to large-scale live network trials — covering 5G SA and NSA, Open RAN (ORAN), and IoT deployments including NB-IoT and CAT-M1. Clients benefit from a managed-service model that handles all scheduling and operational complexity, freeing engineering teams to focus on core product development responsibilities.

Throughout a device's commercial lifecycle, Absolute Validation provides regression testing to validate software updates, firmware releases, and new feature additions before they reach end users. Engineers are trained to identify and report defects as early as possible within each test cycle, maximising the likelihood that fixes can be verified within the same assignment and reducing overall cycle time. Where immediate retest is not feasible, the laboratory's distributed local team network helps minimise turnaround time and associated cost. Absolute Validation can also manage client error and defect databases directly, ensuring systematic defect verification is embedded into every testing round for maximum programme efficiency. Experienced engineers additionally assess device UX and UI quality — evaluating look, feel, and intuitive usability beyond formal test case scope — because issues in these dimensions directly affect end-user satisfaction.

Absolute Validation holds UKAS accreditation to ISO/IEC 17025, the internationally recognised standard for the competence of testing and calibration laboratories. UKAS (United Kingdom Accreditation Service) is the sole national accreditation body appointed by the UK Government to assess organisations providing testing, calibration, inspection, and certification services, and its accreditation signals independently verified competence, impartiality, and integrity to customers and regulators alike. Together, UKAS ISO/IEC 17025 accreditation, GCF RTO status, and GCF ACE designation form a robust, internationally recognised quality framework that distinguishes Absolute Validation as a rigorously vetted testing partner for mobile device manufacturers and network operators worldwide.

Supporting its field and laboratory operations, Absolute Validation operates a secure Knowledge Database portal that provides clients with password-protected access to historical Android application test results, Ookla speed test data imports, location-based filtering tools, and comprehensive technical test evidence archives. The portal is designed for in-depth longitudinal review of validation data, enabling trend analysis and supporting the management of ongoing testing programmes. Reporting across all services is structured to serve dual audiences — engineering-grade evidence capture with detailed dashboards for technical teams, and polished customer-facing summaries for commercial stakeholders — reflecting the laboratory's core commitment to delivering results that can be acted on immediately rather than raw data requiring further interpretation.
