The PURA Act 2001 and the Information and Communications Act 2009 mandate PURA to efficiently manage and monitor the spectrum resources in The Gambia. Specifically PART VII Section 85 to 96 of the Information and Communications Act of 2009 deals with - Allocation and Assignment ofFrequencies and Regulation of theElectromagnetic Spectrum
Spectrum Management is the planning, allocating, assigning, monitoring and controlling the usage of the electromagnetic radio frequency (spectrum) in an efficient and economical manner so as to avoid harmful radio-communication radiation and interference.
The spectrum band ranges from 9 kHz to 3000 GHz.
Spectrum Management functionscarried out by PURA include;
Assignment of frequencies to licensed users
Ensuring Standards specification / type approval
Monitoring and assisting in Enforcement
International notification (ITU - MIFR)
National Frequency Register (database)
International co-ordination and co-operation of radio-communications frequencies
The need for spectrum monitoring cannot be over emphasise and PURA will not be left out. We monitor the radio spectrum to;
Measure / monitor is to know about actual radio spectrum use
Act as the eyes and ears of spectrum management, i.e.feedback and feed forward loops
Protect existing spectrum users
Facilitate new spectrum users
Ensure evidence based – continuously ensuring efficient use of finite spectrum resource
Enforcement spectrum usage
Detect illegal or wrongful use of frequencies or radio equipment
Private Mobile Radio
Private Mobile Radio (PMR) - was developed for business users who need to keep in contact over relatively short distances with a central base station. PMR networks consist of one or more base stations and a number of mobile terminals. Such a system serves a closed user group and that is normally owned and operated by the same organization as its users.
Typically, a communication channel is allocated for the duration of a call and then automatically released to allow it to be used for another call, perhaps between different users on the same system. The technique also enables multiple base stations to be connected and to provide coverage across a wider area than with a single base station.
PMR networks require a frequency assigned by the Regulatory Authority so that communication within its network is interference free and it does not cause harmful interference to other communication networks.
