This is not the case e.g. for wireless routers and devices in personal computers which connect to such routers. Since exemption from frequency licensing is not permitted by Law in the Kingdom, it is necessary for users of such devices to apply for a no-charge, on-line ‘light license’. Type approval All telecommunications apparatus that connects directly to a Public Telecommunications Network and/or which is an intentional transmitter of radio waves are subject to the TRA's Type Approval requirements. Such equipment with a transmitter is referred to collectively as Radio and Telecommunications Terminal Equipment (RTTE). Local manufacturers, authorized importers, and licensed operators are the parties that are eligible to apply for equipment registration of RTTE. Numbering and number portability One of the roles assigned to the TRA is to prepare and maintain a National Numbering Plan (the “Plan”) and allocate numbers to operators in accordance with that Plan. The licenses issued to the operators require that they maintain their own individual numbering plans and provide an annual numbering report to the Authority in compliance with the National Plan. This Plan provides a scheme for the national telecommunications infrastructure, so that competing operators can configure their networks with confidence. The Plan is applicable to all appropriately licensed telecommunications operators wishing to make use of the national resource of numbers. The Plan and its processes and strictures are mandatory on all such operators. Consumer Affairs TRA's Consumer Affairs unit has the two-pronged purpose of protecting consumers and raising awareness levels. Consumer Protection: Based on TRA's Consumer Protection Regulation, TRA protects consumers from breaches in advertising and other products or services. The Consumer Affairs Department investigates these breaches by providing consumers multiple channels to approach them to submit disputes. This includes a toll-free hotline, an online consumer portal and email. Consumer Awareness: The TRA believes that educating consumers with respect to their rights and obligations is vital.
