The characteristics in Table 3.1.1-4 are representative of an average antenna for all User Equipment within a population of RLAN devices operating at 5 725-5 850 MHz. User Equipment can be defined as mobile or portable devices such as smart phones, tablets, notebooks, wireless scanners etc. 3.1.1-4 RLAN User Equipment antenna (mobile/portable device) Gain Antenna height # Type (dBi) ground (m) 1 Omni-directional Antenna 1.3 1 to 1.5 NOTE: This value is the averaged value obtained from a survey on RLAN UE antennas. For simplicity, this antenna is assumed to be isotropic. The antenna pattern in Table 3.1.1-5 is considered as a representative average antenna pattern for indoor access points within the RLAN population operating at 5 725-5 850 MHz. The table specifies the gains available at elevation angles; the antenna pattern is omni-directional in azimuth. 3.1.1-5 Example of Indoor RLAN Access Omni-directional (azimuth) Antenna - Elevation Pattern Gain Elevation angle (Degrees) θ (dBi) 45 90 -4 θ 35 45 0 θ 0 35 3 θ 0 -1 –15 θ -4 –30 θ –15 -9 –60 θ –30 -8 –90 θ –60 The elevation angles in Table 3.1.1-5 are defined from the viewpoint of the RLAN Access Point when mounted to the ceiling. Positive elevation angles are towards the ground and negative elevation angles are towards the sky (typically, the RLAN Access Point is installed for optimal coverage). The pattern is normalised to 3 dBi gain on boresight. 3.1.1-6 sets out the characteristics of RLAN antennas used on fixed indoor or outdoor equipment such as Access Points, Bridges, P2P or P2MP installations. The corresponding antenna patterns are provided in Figure 3.1.1-2 to Figure 3.1.1-5 below. 3.1.1-6 Typical Fixed indoor and outdoor RLAN antenna (access points, bridges, P2P and P2MP) Gain Antenna Antenna # Type Indoor / Outdoor (dBi) pattern Height (m)
