    Azimuth Guidelines for fourth sector
    The loaded sector of 2300 band to be split into two sectors
    The two new sectors with 33° Antenna each (for 2300 band) to be installed at +/- 30°
    of the existing orientation of the loaded sector.
    Table below shows three cases as examples –
    • Case 1 – Cell A (at 0°) to be split into two sectors
    • Case 2 – Cell B (at 120°) to be split into two sectors
    • Case 3 - Cell C (at 240°) to be split into two sectors

    Case 3 Cell C 0° 120° 240° 270° 210°

    As per actual field condition, the two new sectors to be installed at +/- 30° of

    Case 1 : Cell A is loaded - fourth sector to be added with two 33° antennas
    Antenna for Cell A to be replaced with 33° beam width antenna & re-oriented at 30°
    Fourth Sector to be added with 33° beam width antenna at 330° azimuth
    Recommended Angular separation between two new sectors and existing adjacent sec
    tors is 90° as shown in drawing above.

    Angular Separation for fourth sector
    Angular separation between the new sectors and existing adjacent sector
    • Recommended separation is 90° (to achieve desired KPIs)
    • Minimum angular separation is 80° (with 10% overlap & with reduction in KPIs).

    In case the separation is less than 80°, discussion to be done with JIO Team for the fo
    llowing points -
    • the existing sectors may be moved further to achieve this separation of 80°
    • If existing sectors cannot be moved further to achieve the minimum angular separ
    ation, the antenna for that sector to be replaced to 33° beam width. In this case a
    fter antenna replacement, the minimum angular separation can be 60°

    Tilt Guidelines for fourth sector
    The new 33° antenna have a gain of 20 dBi and support electrical tilt of 0 to 6°
    The new antenna would have 3dB attenuation per port from LSMR
    The tilt for the two new sectors using 33° antenna would be same as existing sector
    being replaced : Tilt for New Sectors = Existing Tilt
    Maximum Electrical Tilt supported by the new antenna is 6°. In case existing tilt is m
    ore than 6°, then additional tilt to be achieved by adding Mechanical Tilt.
    Examples
    • Existing tilt is 4° (Electrical) . Then New Tilt = 4°(Electrical)
    • Existing tilt is 6° (Electrical). Then New Tilt = 6°(Electrical)
    • Existing tilt is 8° (Electrical). Then New Tilt = 6°(Electrical) + 2° (Mechanical)
    Electrical Tilt to be provided by setting the knob or scale as shown below

    Attenuation Guidelines for fourth sector
    Maximum EiRP permitted is 63 dBi for 2300 band
    Attenuation of 3 dB to be provided from LSMR for each port
    Attenuation Settings in LSMR for each antenna port = 50,20 as shown below

    Sample - TX Attenuation of 3 dB in LSMR
