| The Mobile BTS or the 'Cell-on-Wheels',
COW in short, developed by Kotkar Energy Dynamics
Pvt Ltd is Mobile Cellular Transmission System,
mounted on a Truck Chassis or Trailer.
The telescopic antenna tower is installed on a truck
platform, and can be lifted, extended and positioned
at desired location. It can be retracted, folded, turned
even and transported.
Description
|
 |
Designed to be mobile the tower is properly reinforced to withstand
vagaries during transit, erection and deployment. Special aluminum
alloy material is used with carbon steel reinforcements. When
installed, steel guys holding on to rigged extension arms mounted
on the platform, support the tower. Additional guys are secured
to the ground to arrest sway at higher wind loads up to 160
km/hr. For retraction and installation electrical winching systems
are provided. The tower mounted on a strong steel pedestal is
bolted and welded to the platform frame. The locking and clamping
systems ensure that the tower is anchored rigidly and firmly
in perfectly vertical position. Tower at the top carries an
aluminum alloy pipe for fixing antennas.
Features
COW incorporates an insulated shelter for housing the BTS
and batteries, a diesel-generator set, a precision type air-conditioner,
RF and MW cable winding and holder drum, counter-weights for
stability, special winches to wind up and pre-load the steel
guys, a jacking system to level platform and lift the vehicle
chassis for 'wheel-free' support, rooted to ground while deployed.
Design
Conforms to the Vehicle Act as a road-plying vehicle
Payload within limits of the vehicle specifications
Withstands wind pressure velocity of 160 km/hr applied diagonally
on complete tower
All installed components are positioned on platform for -
- Uniform weight distribution with low center of gravity
- Easy maintenance and safe operation
- Sustaining transit vibrations and shocks
The design is analyzed on 'Ansys' software for stress, sway
and stability at wind pressure velocity 100 km/hr; and 160
km/hr with additional guys. It has been independently validated
and approved by IIT Delhi.
Advantages
- Rapid Roll - out
- Coverage of special events
- Emergent last minute deployment
- Stand - by for maintenance
- Test Marketing in virgin areas
- Optional where permanent installation is not feasible
- Easy retreat and redeployment
Why KED?
- Pioneers in India
- Proven design in use by leading cellular operators
- Good manufacturing infrastructure
- Excellent quality standards for dependable long-term operations
- Reliable service back up
