Extracts from Government Gazette No. 16820; 17 November 1995 Department of Posts and Telecommunications Notice No. 1790 17 November 1995 DECLARATION OF CERTAIN APPARATUS TO BE AND NOT TO BE RADIO APPARATUS FOR THE PURPOSES OF ACT No. 3 OF 1952 In terms of the powers vested in me by the definition of "radio apparatus" in section 1 of the Radio Act 1952 (Act No. 3 of 1952), I, Zwelidinga Pallo Jordan, Minister for Posts, Telecommunications and Broadcasting, hereby declare the apparatuses mentioned in 1 to 5 below not to be radio apparatus which requires licensing in terms of the said Act. Type approval is obligatory: [...] (2) Wireless spread spectrum Local Area Networks (LAN's); used for hort distance on single sites e.g. in an office complex in the 2,4-2,5 GHz (ISM) band. The standard to be utilised for such systems in this band shall be ETS 300 328 or an equivalent standard. In particular, RF power requirements shalls be in accordance with the standards mentioned which are broadly as follows: The maximum** effective isotropic radiated power is defined as the total power of the transmitter which is -10 dBW (100 mW). The peak power density is defined as the highest instantaneous level of power in Watts per Hertz generated by the transmitter within the power envelope. This shall be -10 dBW (100 mW) per 100 kHz EIRP for equipment using Frequency Hopping Spread Spectrum (FHSS) modulations and -20 dBW (10 mW) per MHz EIRP for other modulation types. The following conditions are applicable: (a) Only equipment which has been type approved by the Postmaster General may be used. Such type approval shall require compliance with the Radio Regulations and the standard stipulated above. (b) No interference may be caused to users of other ISM equipment within the band or to other radio users outside the band. (c) No complaints of interference to spread spectrum systems will be investigated. (d) LAN's shall be confined to the same premises/buildings and between the computer systems of the same user. ** As defined in 5.2.2 and 7.2.3 of the Standard and includes the gain of the antenna in dBi. (3) Wireless LAN's used for short distance, in the following other ISM bands, namely 422,050-434,790 MhZ and 5 725-5 875 GHz for use on single sites e.g. in an office complex. Spread spectrum/wide bnad standards other than ETS 300 328 will be considered within these bands in accordance with the general principles listed in (2) for the 2,4-2,5 GHz ISM band, especially with regard to power requirements.
