Spectrum Management Authority

    Spectrum Management Authority

    Technical and Operational Rules for Radio Communication Equipment using

    the Licence-Exempt Bands

1. Introduction

The declaration of licence-exempt spectrum in Jamaica is aimed at:

    ; Encouraging more efficient and creative use of the spectrum,

    ; Enabling cost effective and innovative technologies, and

    ; Encouraging competition and the creation of new business opportunities in the delivery of

    wireless technologies and services.

    The realization of these objectives is highly dependent on the proper regulation of the spectrum. The purpose of such regulation is to ensure that users of the designated frequencies do not interfere with each other or with other licensed users. The licence-exempt frequency bands will be regulated by controlling the use of the spectrum through technical standards, certification of the transmission equipment, monitoring and enforcement.

2. Purpose

    The purpose of these rules is to establish the technical and operational framework for the use of licence-exempt spectrum, including compliance requirements. The bands to be operated on a licence-exempt basis are:

    ; 902-928 MHz.

    ; 2.4- 2.4835 GHz.

    ; 5.725-5.850 GHz.

3. Summary

    The following arrangements are proposed for radio frequency management in the licence-exempt spectrum.

; Low powered radio communication devices may be operated in the licence-exempt bands

    on a no-interference, no-protection basis. They may not cause radio interference and

    cannot claim protection from interference.

; No licence fee will be required for operation in licence-exempt spectrum.

; Radio Systems may operate within the band 902 -928 MHz, with a maximum power level

    of 1 Watt with bandwidth of 250 KHz and 0.25 Watts with bandwidth of 500 KHz.

; Radio Systems may operate within the band 2.4 -2.4835 GHz, with a maximum power

    level of 0.125Watts and minimum bandwidth of 1 MHz.

; Radio Systems may operate within the band 5.725- 5.850 GHz. with a maximum power

    level of 0.75Watts and a minimum bandwidth of 1 MHz.

; Radio Systems with design specifications which conform to the technical conditions as

    stated herein, will not be the subject of individual licences, but must satisfy the

    requirements for type approval as established by the Spectrum Management Authority.

; Enforcement of the rules related to the licence-exempt spectrum will be carried out

    pursuant to the Telecommunications Act 2000 and the Radio and Telegraph Control Act.

; Penalties shall be applied to entities found in breach the rules governing the use of the

    licence-exempt spectrum.

    4. Definitions

    For the purposes of this document,

    ; Urban refers to the Kingston Metropolitan Region, inclusive of the parishes of Kingston,

    St. Andrew and St. Catherine.

; Rural refers to all areas outside of that defined as urban.

    ; Public Radio System A public radio system is one where the beneficiary of the system

    might not be the licensee or anyone concerned with the business of the licensee. The

    licensee may receive a payment, consideration or other benefit, wither directly through a

    contractually managed fee or indirectly through standing charges levied at a point of sale

    of any equipment to be connected to the system or by any other means, in payment for

    the service of providing and maintaining the radio facility for use by third parties.

    ; Private Radio System - A private radio system is one where the purpose and exclusive

    benefit of use of the radio system is solely in the interest of the licensee’s business. This

    may include use by third parties such as contractors where the work/radio use of that

    third party is on behalf of the licensee and does not include any traffic that is not

    connected with the business of the licensee. Communication should be solely concerned

    with the business of the licensee, who will receive no payment, consideration or other

    benefit from any third party in respect of the provision of radio communication facilities.

; Short Range Devices (SRD’s) - This covers a variety of radio devices providing either

    unidirectional or omni-directional communication (point to point or point to multipoint)

    and which, due to their low transmitter power, have a low risk of interference to other

    devices.

5. Technical Requirements

The licence-exempt bands are,

    902 928 MHz

    2.400 2.4835 GHz and

    5.725 5.850 GHz.

    The modulation methods of the equipment that will be allowed in these bands are those methods that minimize the mutual interference caused by multiple devices operating in the same band with geographic overlap. In this regard the two (2) most common forms of spread spectrum techniques are:

    (i) Frequency Hopping Spread Spectrum , FHSS, and

    (ii) Direct Sequence Spread Spectrum, DSSS.

902 928 MHz Band

    For systems operating with FHSS technique, if the minimum bandwidth of the hopping channel is 250 kHz, then the minimum number of hopping channels shall be 50, the average time in each hopping channel shall be 0.4 second within a 20 second period, and the maximum peak output power shall be 1Watt. For FHSS systems with hopping channel of minimum bandwidth of 500 kHz, the minimum number of hopping channel shall be 25, with the average time in each hopping channel being 0.4 seconds within a 10 second period, and the maximum peak output power shall be 0.25 Watt.

2.4 2.4835 GHz Band.

    The hopping channels shall have a minimum bandwidth of 1 MHz. If the minimum number of hopping channel is 15, then the average time within the hopping channel shall be 0.4 sec. times 15 (hopping channels), and the power shall be 0.125 Watt. If the minimum number of hopping channel is 75, then the average time within the hopping channel shall be 0.4 sec. times 75.

Spectrum Management Authority

5.725 5.850 GHz Band

    The hopping channels shall have a minimum bandwidth of 1 MHz. The minimum number of hopping channels shall be 75, the average time within each hopping channel shall be 0.4 sec. in a 30 sec. period. The maximum output power level shall be 0.75 Watts.

    DSSS systems operating in all three bands shall occupy at least 500 kHz at the 6 dB point, with the maximum peak output power being 0.5 Watt in urban and 1 Watt in rural areas.

Out of Band Emissions

    In any 100 kHz bandwidth outside the frequency band in which the spread spectrum system is operating, the radio frequency power that is produced by the system shall be at least 30 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power.

    ; RSS-210 (Canadian )

8. Certification and Registration

8.1 All equipment must satisfy the SMA’s type approval requirements as presented in

    Appendix 2. The process of type approval involves an assessment of the technical

    specifications of the device to ensure that it is suitable for operations in the licence

    exempt bands in Jamaica and that it conforms to the required international standards. 8.2 To facilitate individual importation of radio equipment which are not for purposes of re-

    sale, the Department of Customs will hold a list of pre-approved equipment which satisfy

    the type approval requirements of the SMA

    8.2 All entities which intend to offer a service to the public must first obtain the requisite

    service provider licence from the Office of Utilities Regulation, before registering with

    the Authority.

9. Interference Management

    9.1 Devices shall not emit more energy than is required for their intended functions. The

    limits stated in these rules may not prevent harmful interference under all circumstances. 9.2 The operation of equipment within the licence exempt spectrum would be on a no-

    interference, no-protection basis. This means that licence exempt users of the spectrum

    must not cause interference to other licensed users, nor could they claim protection from

    interference from such users.

    9.3 Users of licence-exempt devices are required to cease operation immediately should

    harmful interference occur to licensed users of the radio spectrum.

    9.4 The parties responsible for the equipment should employ the minimum field strength

    necessary and provide greater attenuation of unwanted emissions than required by these

    rules in line with good engineering practice. In any case, devices should not exceed the

    limits established by these rules.

    9.5 Complaints of interference by licence exempt users will not be investigated by the

    Spectrum Management Authority.

10. Enforcement

    10.1 All activities within the licence exempt spectrum must comply with the

    Telecommunications Act 2000, the Radio and Telegraph Control Act, where applicable

    and regulations thereto, as well as these rules as prescribed by the Spectrum Management

    Authority.

    10.2 It is an offence under the Telecommunication Act 2000 to install and use unauthorized

    radio communication equipment, within the declared unlicensed bands.

    10.3 If an equipment type does not comply with any of the approved standards as stated in

    these rules, it is regarded as “non-standard”. Operating non-standard equipment is an

    offence under the Telecommunications Act 2000.
