This page provides an overview of some projects lead by Bolt & Yurdal Consulting ApS. 


  • Review of the licensing and assignment processes for the CITC (Communications and Information Technology Commission) in the Kingdom of Saudi Arabia

In the framework of a project led by MSI dealing with the review of the regulatory framework in Saudi Arabia including the update of the national table of frequencies, revision of the licensing fees, review of the licensing policy), BoY has been reviewing the licensing and assignment processes in order to propose revisions based on the "best practices" found in other countries. In addition, solutions were proposed in order to address the congestion issues reported by the CITC in some bands (PMR, Fixed Services...).

  • 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 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.

  • Training of market surveillance officers for the implementation of R&TTE Directive

As part of a EU project, led by the British Standardisation Institute (BSI), BoY provided training sessions for the market surveillance and conformity assessment staff of the Turkish telecommunication regulator and customs officers for the proper implementation of the R&TTE Directive of the EU. The training covered all requirements of R&TTE Directive, including the practical application of these requirements.

  • Dispute resolution between MMDS system and Broadcasting Satellite Network

BoY prepared a report to assess the coordination requirements for Multi-channel multipoint distribution system (MMDS) of an EU country and the Broadcasting Satellite (BSS) network of another neighbouring EU country, both operating in the Ku band frequencies. The report explains the ITU coordination procedures between the services to which the frequency band is allocated to both of them on a primary basis. BoY also coordinated the situation with ITU space and terrestrial services departments and mediated the conflict between the MMDS operator-related administration-ITU by also contacting that EU administration.


  • Resolution of “black marketing” for “metering” systems

BoY helped a Danish “metering” manufacturer to access the market in a EU country which was not able to access properly due to the black propaganda of a bigger German “metering manufacturer”. BoY contacted the Croatian Telecommunications Regulatory Authority and mediated the resolution of this black marketing case.

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

BoY provided support to IFAK (Institut f. 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 at As a 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 developed in order to allow for the introduction of WIA in this frequency range. The figure below illustrates the case where over a factory/plant, 10 production halls are deployed, each of them contains cells where wireless industrial applications could be deployed in order to control the production on the site instead of using a wired infrastructure. The deployment of wireless infrastructure is expected to be more flexible and less expensive than the use of a wired infrastructure. 



As a follow up of this project, BoY attended to WP 5D in 2016 in order to follow the discussions relating to WRC Agenda Item 9.1.8 dealing with Resolution 958 (WRC-15) - Urgent studies required in preparation of WRC-19 - Narrowband and broadband machine-type communications infrastructures.


  • Reports dealing with PMSE (Programme Making and Special Events) systems

In the framework of WG FM 51, BoY provided support to the APWPT (Association of Professional Wireless Production Technologies) to develop ECC Report 206  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.

  • Compatibility studies for Audio PMSE (Programme Making and Special Events) in the frequency range 1350 - 1400 MHz and 1492-1525 MHz

In the framework of WG SE 7, BoY provided support to the APWPT (Association of Professional Wireless Production Technologies) in the development of an ECC Report dealing with compatibility between PMSE and existing systems in the frequency range 1350 - 1400 MHz and 1492 1525 MHz. The reports were published as ECC Report 245 and ECC Report 253. The development of those reports led to the identification of the band 1350 - 1400 MHz for Wireless Microphones (see Recommendations 70-03 and 25-10).


  • Development of compatibility studies using SEAMCAT

SEAMCAT stands for Spectrum Engineering Advanced Monte Carlo Tool and is developed in the framework of WG SE. BoY is following the development of SEAMCAT through regular attendance to the STG in order to develop compatibility studies. We have contributed to the studies of various ECC Reports such as ECC Report 245 and ECC Report 253 by providing simulations based on SEAMCAT. We have also developed internal report/studies based on specific demands outside the framework of the ECC.
