T54 14.8 -49.2 7.8 Some transmitting points’ pictures in Building B are shown in Figs 95 to 96. 95 The transmitting point in the lobby on the 1st floor in Building B (In transmitting point the receiving point can be seen through glass) 96 The transmitting point next to the elevator on the 2nd floor in Building B 16.2 Test methodology In Building A and B, 11 frequency points are selected for each frequency band, e.g. 3.5 GHz, 5 GHz, 15 GHz, 24 GHz, 28 GHz and 31 GHz. 16.2.1 Measuring system and instrument The devices of measuring system are shown in Table 40. TABLE 40 The antenna selection consideration Transmitting antenna Omni-directional vertical polarization antenna (for 3.5 GHz) Horn vertical polarization antenna for 5-31 GHz band Receiving antenna Omni-directional vertical polarization antenna. (for 3.5 GHz) Horn vertical polarization antenna for 5-31 GHz band Transmitter Agilent E8267D signal generator RF power amplifier The output power in the test is set to 33 dBm for 3.5 and 20 dBm for GHz band Receiver Agilent N9030A signal analyser We have developed an automatic program in order to control instruments and record test data by LAN. In each location and frequency points, 500 continuous reading is got which will cost about 8 ~ 10 seconds. 16.3 Calculation method of building entry loss The free space loss can be calculated as: (17)
