AIR GIGARAY 70 GHz Technical Specification 2. GLOBTEL GIGARAY SOLUTION 2.1. General Description Globtel GIGARAY system is a unique wireless point to multipoint solution that enables operators to offer their customers full set of triple play services. System is especially suitable for areas with less developed infrastructure as it can be set-up very quickly and can cover wide area at once. It can deliver fiber-like services without the need for construction works, roadblocks and long deployment times.
AIR GIGARAY 70 GHz Technical Specification 2.1.2. SPECTRUM One sector antenna has 90° coverage. Four sector antennas with 90° coverage are used to achieve 360° coverage. Each sector can utilize up to 500 MHz of frequency spectrum in range from 69 000 MHz to 71 0000 MHz for downstream and 500 MHz of frequency spectrum in range from 81 000 MHz to 83 0000 MHz for upstream. System allows different combination of sectors from a single sector setup to a fully equipped 4 sector base station.

5.1.2. Base station sector assembly The base station sector is assembled from the mounting part and the sector antenna part. Bellow picture showing both components separated.
Before any assembly all nuts and bolts have to be loosen on the mounting par as shown on bellow picture. Nuts and bolts to be loosen Nuts and bolts to be loosen Figure 8: Mounting part in detail We take the nut, washer and bolt from the far end of the eye cable tensioner and from the mounting part. The mounting part is than assembled to the sector antenna part as shown on bellow picture.
Figure 9: Assembly of sector antenna and mounting part When the mounting part is fitted to the sector antenna we insert all the bolts, nuts, washers and begin to tighten them. How the bolts are inserted is shown on bellow picture. The bolt head has to be always on the outside as shown in picture.
Wrench 13 for the screw and the M8 hex nut Bolt M8x18 Washer Sector antenna Mounting part Washer (normal, spring) Nut M8 Figure 10: Bolt assembly The eye cable tensioner is fitted to one of the holes on the sector antenna. The angle between the mounting part and the sector antenna should be app. 95°. Now the sector antenna and mounting part are prepared to be mounted on the mounting pole. Before the actual mounting is done the metal jaws on the mounting part have to be loosened. Loosen these bolts.
When the bolts are loosen the jaws for the mounting pole can be opened. Figure 12: Metal jaws 5.2 Antenna mounting When the sector antenna is mounted to the desired position on the pole we close the metal jaws and tighten the bolts so much that the antenna stays at the desired height. Now we align the antenna to the desired direction and tighten the bolt with app. 38 Nm strength.
Bolts tightened to allow directional positioning of the antenna.
The distance has to be symmetrical mounting pole Figure 14: Distance front and back on jaws Proprietary & Confidential Maribor, 25 June, 2021 Page 19 of 27
5.3 5.3.1 Antenna positioning Elevation antenna positioning Step 1: loosen the nuts on the mounting part with wrench nu. 13 Step 2: loosen the nut on the lever with wrench nu. 13 Turn clockwise or counterclockwise to adjust angle. Figure 15: Positioning guide part 3 Step 3: Apply some grease. With the help of an allen wrench adjust the tilt to the desired elevation; the default angle is set to 0°.
