Installation

METCOM has vast experience in base station system telecommunication equipment installation including GSM900/1800, CDMA2000 and WCDMA (wireless local loop).
Our expertise covers Base station controllers (BSC), Radio access controllers (RAC), Packet control units (PCU), LAN switches, BAM servers, Short message servers, internal signal cables, network and trunk cables, optical fiber.
These involve hardware and software installation.
The base station system (BSS) equipment installation is categorized into three;
RF and BTS installation
Microwave/transmission installation
DC power supply system

METCOM carries out professional technical executions starting from project plan and kick off co-ordination up to acceptance and handover to the client.
RF and BTS installation
The antenna & feeder system can either be for outdoor or indoor.
For outdoor, the BTS is either mounted on a platform or up on the tower.
In the indoor mode, the BTS is installed inside an equipment room. In all the cases, the antennas can be directional or omni-directional.
The antenna and feeder system is installed either on a tower or on a roof (rooftop).
Microwave/transmission installation.
Our microwave/transmission team has hands on technical experience on radio transmission ranging from mini-links to back-bone transmission equipmentinstallation including their indoor and outer radio units, and all the accompanied networks. These networks can be E1, SDH, optical or combined networks.
DC power supply system
This includes the storage batteries, rectifier cabinet and its associated cabling on to the BTS.
The storage batteries help to supply DC power in case of a power outage.

Maintenance;

System maintenance involves both hardware and software but most significantly is the hardware.
The maintenance is done locally (local maintenance), the equipment local maintenance software installed on the laptop connected to the equipment with serial connection cable. The local maintenance of the equipment is then implemented via the MMI (man machine interface). Communication equipment maintenance is done routinely to enable normal system operation in different running environment. This helps to provide information;

What is to be done in routine equipment maintenance?
How to do them correctly.
What basic methods to be adopted and what references have to be taken into consideration in local office routine maintenance solution. Routine maintenance is classified by either implementing method or period of length;
By implementing method;
i. Conventional maintenance
This is mainly done by observing testing and analyzing the equipment
performance and running conditions by means of normal maintenance.
ii. Unconventional maintenance

To check whether or not the equipment performance has degraded by aging through observing, testing and analyzing it in artificially-created special circumstances.
By period length
i. Unscheduled maintenance
Maintenance tasks incurred by equipment fault and network adjustment, for
example, maintenance operation required at the time of user complaint,
equipment damage and line fault.
ii. Daily maintenance
Maintenance operation conducted everyday, which helps maintenance personnel keep track of equipment running condition get problems solved in time.
iii. periodic maintenance
Maintenance operation conducted regularly, which helps maintenance personnel keep of the long time performance of the equipment
