He spent 5 year (1998-2004) at ANFR (the French spectrum regulator) as a spectrum engineer participating to ETSI, ECC (SE21, SE19...) and ITU-R meetings (WP 7C, WP 7D, WP 9D....). He was in charge of the development of the SEAMCAT compatibility tool for the French regulator. He acted as a CEPT coordinator for one the agenda item at the World Radiocommunication Conference (WRC) 2003 dealing with satellite and Radio Astronomy services.

He was hired by the ECO (former ERO) as an expert (2004 - 2012) to work in the field of the Digital Dividend and worked as a CEPT representative in the group dealing with the technical preparation of the Regional Radiocommunication Conference (RRC) in  dealing with the Digital Dividend 2004 and 2006. He also chaired SE24 dealing with short range devices during these 8 years.

In 2009, he was appointed as the Deputy Director of the ECO where he was supporting the ECO Director Mark Thomas, He supervised the development of the new web site an manage also the development of communication documents such as the first Annual Reports for the ECO or document dealing with the regulations in Europe. He was also in charge of developing the templates for the ECC documents (Decision, Recommendation, Report), which are still used today. In addition, he set up the first CEPT Workshops on European Spectrum Management and Numbering.

After leaving ECO in 2012, he joined the consultancy company "Bolt & Yurdal Consulting ApS" in Denmark, and has been working as a consultant in the field of telecommunication regulations since then.

For specific requests, he has developed technical reports dealing with compatibility issues.

He acted as a technical Expert for ETSI project STF 541 dealing with Signal interferer handling leading to the publication of ETSI TS 103 567.

He is currently rapporteur for the development of DEN/ERM-TG28-561 (EN 303 659) dealing with networked SRD in 865-868 MHz and 915-919.4 MHz in the framework of ETSI TG28. The standard was published in the beginning of 2025.

He is participating to various meetings in CEPT (SE24 and SRD-MG (Short Range Devices), FM44 (satellite)) and ETSI (TG 28 and ERM). In particular, he is involved in the framework of the development of the regulatory framework for SRD communicating with satellites. He is monitoring the ECC activities relating to networked SRD in different groups.

He is familiar with SEAMCAT (following the development of the tool since 1998), Matlab, R (a tool to work with Data Bases) and with some of the ITU-R BR space tools (Space Cap and Space Pub).

Frequency designation for Medical Body Area Network System (MBANS)

BoY assisted to Philips (The Netherlands) to develop a European regulation and to have the necessary frequency band designated for the operations of MBANS system in Europe. A system reference document has been developed and approved by ETSI (by ERM TG30), a regulation was developed by CEPT/ECC (SRD/MG group) which was included in ERC Recommendation 70-03. The band 2483.5-2500 MHz was designated to MBANS at the end of these studies. Finally, a harmonised standard (EN 303 203) was developed and approved by ETSI/ERM which was published in December 2014.

Frequency designation for Narrow-band Point-to-Multipoint (nP2M) paging system

BoY acted as the rapporteur for the development of a system reference document for nP2M systems by TG DMR of European Telecommunication Standards Institute (ETSI). After developing and having it approved by ETSI, BoY coordinated the necessary activities within the Frequency Management working group of CEPT/ECC Committee (WG FM). At the end of these studies, led by BoY within WG FM, the 430-470 MHz band was designated to nP2M system as a tuning range. Also, nP2M system was recognised by this way and included in the CEPT/ECC deliverables, such as ECA Table and EFIS database).  

Worldwide frequency allocation for automotive radars

A worldwide frequency allocation process has been initiated by the automotive industry, led by Robert Bosch of Germany, in 2010. The aim was to have the 77.5-78.0 GHz band allocated by the ITU World Radiocommunication Conference (WRC-15) to Radio Location Service for use by automotive radar. BoY acted as the coordinator of the issue at the ITU level by chairing the relevant sub-working group within ITU-R WP 5B. BoY played a major role for the development and approval of Report ITU-R M.2322 which covers systems characteristics and compatibility of automotive radars operating in the frequency band 77.5‑78.0 GHz for sharing studies. BoY contributed to the report by conducting sharing studies (SEAMCAT and MCL calculations) between the automotive radars and incumbent services (Amateur, Amateur Satellite and Radio Astronomy) to which the 77.5‑78.0 GHz band allocated. The report concluded that automotive radars are compatible with the incumbent services, so that the 77.5‑78.0 GHz band can be allocated to radio location service for use by automotive radars.

Report development for frequency designation of Wireless Industrial Applications (WIA)

BoY provided support to IFAK (Institut For Automation und Kommunikation - Germany) in the development of an ECC Report dealing with the possible introduction of Wireless Industrial Applications (WIA) in the frequency range of 5725 to 5875 MHz. The results of those studies have been published as ECC Report 206. As the consequence of the results given in ECC Report 206, a revision of ERC Rec. 70-03 (Regulatory instrument in Europe for Short Range Devices) was amended to allow the introduction of WIA in this frequency range. 

Report development for the PMSE (Programme Making and Special Events) systems

BoY provided support to the APWPT (Association of Professional Wireless Production Technologies) to develop ECC Report 204, providing information about PMSE usage during exceptional events such as the Olympic Games or the Tour de France.

This report also addresses the different sectors of the PMSE industry: Audio links, Video PMSE and Service Links.

Authorisation of satellite communication services of Avanti Communications-UK and establishment of two in-country earth stations in Konya-Türkiye

BoY assisted Avanti to obtain authorisation from the Turkish telecom regulator to built and operate earth stations in Türkiye. Having in-country earth station(s) is a must in Türkiye to provide satellite communication services mainly for the "lawful interception" purposes. The consultancy services provided by BoY included assistance in all aspects starting from the application for a license, up to the start of operations.

Development of ECC Report on the use of SRD applications in cars in the band 5725-5875 MHz 

BoY signed a contract with the European Association of Operators of Toll Road Infrastructures (ASECAP) to involve in a project to be realised by CEPT/ECC to investigate the use of SRD applications in the band 5725-5875 MHz in cars equipped with 5.8 GHz road toll equipment, WAS/RLAN use in cars based on the 5.8 GHz SRD regulation as well as co-channel ITS communications (5855-5875 MHz) which are all operating under the existing SRD regulations. The aim of the project was to investigate the potential problems when having all these applications implemented in the same car within close proximity to each other. Studies led by BoY within CEPT/ECC/SE24 completed successfully with the development and publication of ECC Report 277 (Use of SRD applications in cars in the band 5725-5875 MHz).
