Britten-Norman Prepares BN2T-4S Islander for Airborne 5G Testing
Britten-Norman integrates advanced 5G antenna on BN2T-4S Islander for flight tests in 2026, enhancing airborne connectivity in the UK.

This article is based on an official press release from Britten-Norman.
We are tracking a significant milestone in the development of airborne telecommunications. According to a recent press release, UK-based aircraft manufacturer Britten-Norman has completed the structural and engineering preparations necessary to integrate an advanced 5G antenna system onto its BN2T-4S Islander aircraft. This development marks a critical phase in the company’s ongoing collaboration with World Mobile Stratospheric (WMS) to deliver high-speed internet connectivity directly from the sky.
The aircraft is currently stationed at Britten-Norman’s Maintenance, Repair, and Overhaul (MRO) facility, where the installation of the proprietary phased-array antenna is underway. Flight testing is scheduled to commence in the summer of 2026 near Ipswich, UK. The program aims to validate the use of aircraft-based 5G systems to provide real-time mobile coverage to remote communities and rapidly restore communications in disaster-stricken regions.
While the Islander will serve as the initial testbed, industry research indicates that this phase is a vital stepping stone toward a much larger goal: the deployment of autonomous High-Altitude Platform Stations (HAPS) operating in the stratosphere to provide wide-area, direct-to-smartphone connectivity.
Engineering the Airborne 5G Platform
The BN2T-4S Islander Testbed
Adapting a traditional aircraft to carry heavy, high-powered telecommunications equipment presents a complex integration challenge. According to the Britten-Norman press release, the company’s Design Office produced over 100 individual engineering drawings to support the structural analysis, power management, and safe mounting of the antenna system.
Industry data highlights why the BN2T-4S Islander was selected for this rigorous testing phase. Acquired by WMS in November 2025, the BN2T-4S is a larger, turbine-powered variant of the iconic Islander, equipped with twin Rolls-Royce M250-B17F turboprop engines. It features a stretched fuselage that provides 30 percent more internal cabin space than its piston-powered predecessor. With a Maximum Take-Off Weight (MTOW) of 8,925 lbs and an endurance of up to eight flying hours, the aircraft offers the ruggedness and payload capacity required for iterative, real-world data gathering.
“The scale of the design effort reflects the complexity of integrating advanced communications systems onto the Islander platform and demonstrates the depth of engineering capability within Britten-Norman,” stated Mark Shipp, Technical Director at Britten-Norman, in the official release.
Advancing High-Altitude Telecommunications
From Low Altitude to the Stratosphere
The core technology driving this initiative is a highly advanced phased-array 5G antenna. Background research reveals that the system utilizes 500 individually steerable beams, allowing operators to direct targeted, high-speed coverage to specific locations on the ground. The system is designed to deliver connection speeds of 150 to 200 Mbps directly to standard consumer smartphones.
During the upcoming summer 2026 test-flights, the Islander will broadcast over an approximate 15-kilometer radius. However, the ultimate vision for WMS extends far beyond traditional aviation altitudes. The technology is intended for High-Altitude Platform Stations (HAPS), aircraft designed to operate in the stratosphere at altitudes of 60,000 to 70,000 feet. At this height, a single stratospheric platform could eventually cover an area of up to 15,000 square kilometers.
Following successful validation on the Islander, WMS plans to transition the technology to an autonomous, liquid-hydrogen-powered aircraft known as the “Stratomast,” which is projected to sustain flights for up to a week at a time. Test flights for the Stratomast are targeted for 2027.
Strategic Partnerships and Real-World Impact
Connecting the Unconnected
The airborne 5G program is the result of extensive corporate collaboration. World Mobile Stratospheric is a joint venture between US-based telecom provider World Mobile and Indonesian digital infrastructure company Protelindo. The technology itself was originally developed by Stratospheric Platforms Ltd (SPL), which has since been subsumed into WMS.
British Telecom (BT) has also been a foundational partner. Since early 2023, BT has been testing the proprietary 5G antenna at its Adastral Park R&D facility in Suffolk, ensuring seamless integration with secure 5G architectures and Open RAN testbeds. The upcoming flight assessments will be conducted by Britten-Norman’s flight operations team in close cooperation with both WMS and BT.
“We are very happy to have reached this important milestone in our joint work with Britten-Norman to deliver connectivity from the sky – both for disaster resilience using the Islander platform and, ultimately, for wider communications coverage,” said Richard Deakin, CEO of World Mobile Stratospheric.
AirPro News analysis
We view the Britten-Norman and WMS collaboration as a highly pragmatic approach to a notoriously difficult engineering challenge. By utilizing the proven, rugged BN2T-4S Islander as a low-altitude testbed, the consortium can iteratively refine beam stabilization and network integration without the immense costs and risks associated with immediate stratospheric drone testing.
Furthermore, the HAPS concept presents a compelling alternative to Low-Earth Orbit (LEO) satellite constellations like Starlink. While LEO satellites provide global coverage, they often require specialized ground receivers and can suffer from latency issues. The WMS phased-array antenna promises 150 to 200 Mbps directly to standard, unmodified smartphones. If successfully scaled to the stratosphere, this technology could bridge the gap between terrestrial cell towers and satellite networks, offering a highly effective solution for rural “white spots” and rapid disaster response.

Archer Aviation and AEG to Build eVTOL Vertiport at LA LIVE
Archer Aviation and AEG announce a multi-year partnership to develop an eVTOL vertiport at LA LIVE ahead of the 2028 Olympics.

Archer Aviation Inc. and Anschutz Entertainment Group (AEG) have established a multi-year partnerships to construct a dedicated vertiport for electric vertical takeoff and landing (eVTOL) aircraft at the L.A. LIVE district in downtown Los Angeles.
Announced in an August 24, 2026 press release, the agreement establishes Archer as the exclusive air taxi partner for the 4 million-square-foot sports and entertainment complex. The project serves as a central node for Archer’s planned Southern California network, targeting operational readiness ahead of the 2028 Olympic and Paralympic Games.
Infrastructure and Network Expansion
The two companies have completed an initial feasibility study for the L.A. LIVE site. This assessment evaluated land-use requirements, airspace integration, power availability, and community impact. The project has now advanced to a secondary phase focused on operational procedures and passenger experience.
To support flight operations, the facility will incorporate electric aviation chargers manufactured by BETA Technologies. This hardware integration aligns with the Advanced Air Mobility (AAM) industry’s ACES consortium, which aims to standardize charging infrastructure across different eVTOL platforms.
The downtown location will connect to a broader regional network. According to reporting by Aviation International News, Archer’s Los Angeles architecture includes a central operational hub at the newly acquired Hawthorne Municipal Airport (KHHR). Additional planned nodes include Los Angeles International Airport (KLAX), Hollywood Burbank Airport (KBUR), John Wayne Airport (KSNA), SoFi Stadium, and the University of Southern California. Pollstar News reports that passenger travel times across this network are estimated between 10 and 20 minutes.
Aligning with the LA28 Games
The vertiport development is closely tied to the upcoming LA28 Olympic and Paralympic Games. The Downtown Los Angeles Zone is scheduled to host 18 Olympic and Paralympic sports, positioning L.A. LIVE adjacent to Crypto.com Arena and the Los Angeles Convention Center as a high-traffic transit corridor. Archer previously secured the designation of Official Air Taxi Provider for the LA28 Games and Team USA.
Archer Founder and CEO Adam Goldstein highlighted the strategic timing of the infrastructure build.
“Working with AEG on an iconic project like this vertiport at L.A.

AEG Global Partnerships President and Chief Operating Officer Nick Baker stated the collaboration blends infrastructure and technology to serve event attendees and the broader community.
Unconfirmed Site Details
While the partnership is confirmed, specific logistical details remain undisclosed. Aviation International News noted that the exact footprint of the vertiport within the L.A. LIVE campus has not been specified. Potential locations could include existing parking structures, including one with a 100,000-square-foot rooftop deck, though neither Archer nor AEG has verified a specific location. Funding structures, ownership models, and specific operational responsibilities for the vertiport also remain unannounced.
AirPro News analysis
Securing viable takeoff and landing real estate in dense urban centers remains one of the highest barriers to entry for the AAM sector. By partnering directly with AEG, Archer bypasses several municipal land-acquisition hurdles, leveraging existing private commercial space in a highly regulated downtown corridor. The decision to install BETA Technologies chargers is equally significant. We view this hardware choice as a pragmatic step toward interoperability, ensuring the site can potentially service mixed fleets in the future rather than operating as a closed ecosystem. The success of this node will likely depend on local airspace deconfliction over downtown Los Angeles and the finalization of high-capacity grid connections required for rapid turnaround times.
