Legal basis for the work of the National Radio Frequency Spectrum Council (CNRFS) is the Law on Telecommunications, published in issue 88 of the State Gazette (7 October 2003), amended in March 2005. The link here is to the official English translation.
"Resolution of the Communications Regulation Commission (CRC) No 717 (12.02.2004) for determination of the radio frequency spectrum for common use" - the original text in Bulgarian is on page 29 of this document; amended and supplemented by Resolution No 255 / 10.02.2005 and General License No 220, for mobile telecommunication services offered through public RLANs - in Bulgarian and English. This seems to anticipate a problem of mobile phone operators potentially "crowding out" ordinary citizens who use WiFi as UMA and GSM/WiFi convergence expands.

IDG's Bulgarian ICT Market Weekly Review of 26 November 2004 quotes an article in newspaper Sega to the effect that the Communications Regulation Commission (CRC) signed an agreement with Italy's telecom regulator aimed at helping CRC harmonize Bulgaria's communications laws with European Union directives by 2007.
"Bulgarian telecoms regulator CRC is currently laying down the foundations for the country's new Telecoms Act, which will be introduced in 2006, according to Pari Daily. The new legislation aims to establish new standards for data services, transfer and protection. It will also establish a legal framework for the introduction of new electronic services. Alternative operators will welcome the legislation, as it will allow them access to the infrastructure of the former monopoly BTC. The incumbent still controls about 90% of the country's fixed-line market. The new Telecoms Act 2006 is expected to boost competition in the fixed-line and broadband sectors, and set the framework for the digital revolution." ---INA Southeast Europe ICT Weekly Update, 14 October 2005.

"EC action against Bulgaria on hearing aid frequencies,"Sofia Echo in English, 28 January 2010: "The European Commission (EC) said on January 28 2010 that it had started legal action against Bulgaria and called on it to make sure the technical requirements are in place for hearing aids, social alarms and emergency buttons at home, for old and disabled people. Bulgaria has not followed EU rules saying the 169 MHz frequency band should be made available to applications of social value and electronic services such as asset tracking and paging systems, the EC said... The current Bulgarian Radio Frequency Plan, last modified in 2006, allocates the 169.4-169.8125 MHz frequency band to radio services which are restricted for the purpose of national security and defence. According to EU rules, 169 MHz band can be used not only for legacy paging systems, but also for hearing aids, social alarms, asset tracking or tracing systems and meter reading systems.
