PU Cabin Inside View

Equipments are installed inside a cabin of 4m x 2.5m area.

The Major Materials used for this cabin are Polyurethane Panels completed with two superficial pre-coated Color Bond Steel Sheets.

Generally used for HUB sites where non waterproof transmission cabinets need to be installed.

MDB, DC ventilation system, alarm panels, cable entry & overhead cable ladder are installed during civil construction.

APM & IBBS or battery rack is installed as per layout.

Shared Site:

APM, IBBS, ODF & wall mount LSC Battery Rack

Equipments are installed inside the BTS room of other operator (Qubee’s site sharing partners).

Existing facility for Antenna system, such as, tower or poles can also be shared.

All equipments are installed as per the approved layout from both operators.

Suitable for planning HUB sites.

AC or DC power is shared from existing system.

Cable ladder, cable entry, ventilation system & grounding system are also shared.

Antenna & RRU Placement & Height Measurement Procedure

Antenna & RRU Placement

Most Common Solutions Poles (9m, 6m, 3m) Wall mount

Other Solutions 3m single frame with 9m poles. 6m double frame with 9m poles. 12m & 15m tower. Different types of mounting kits for pole & tower.

Antenna height should always be measured from the road level to the antenna middle level.

Road level should always be considered as 0 meter.

Antenna length is 1.2meter. So mid-length is 0.6meter.

RRU is installed 1m below from antenna.

Antenna & RRU Height Measurement Procedure


Incorrect Method (Height Measured from building ground floor)

Correct Method (Height Measured from Road level)

Three kind of Cases may occur during height measurement:

Case-1: Building Ground Floor level & Road level same Case-2: Building Ground Floor level is higher than Road level Case-3: Building Ground Floor level is lower than Road level


Case-1: Building Ground Floor level & Road level same

Road Level is always considered as 0m

Building ground floor level = 0m

Roof level = 15.6m

Pole height = 9m

Maximum Antenna height = (15.6 + 9) – 0.6 = 24m


Case-2: Building Ground Floor level is higher than Road level


Building ground floor level = 1.5m as there is a 1.5m stairway from road level.

Antenna height should be measured from road level.

Roof Level = 1.5 + 15.6 = 17.1m

Pole height = 9m

Maximum Antenna height = (17.1+ 9) – 0.6 = 25.5m


Case-3: Building Ground Floor level is lower than Road level


Building ground floor is 2m below the road level.

Antenna height should be measured from road level.

Roof level = 13.6m

Pole height = 9m

Maximum Antenna height = (13.6 + 9) – 0.6 = 22m



The TSSR provides the following information: General site information (such as site ID, address, lat/long, etc.) RF information (sector height, azimuth, tilt) Equipment room layout with proposed equipments. Roof layout & elevation layout with proposed equipments. Location Map. Cable information. Scope of civil works. Site Pictures.
