Repeater deployment could provide significant cost savings in:

Structure Requirements – No shelter is required

CME works – light weight structure

Power Consumption – less power backup and no air-condition

required

Manpower – faster deployment

Mobilization – light weight loading

Cost Saving

Repeater Deployment could provide time savings in:

CME works – light weight structure

Local Council/ Authorities Approval – much simpler site model

Manpower – simpler site, faster deployment

Overall Site Implementation

Time Saving

There is no way that BTS could be completely replaced by repeater as its coverage is relied on the nearby donor BTS site. However, repeater solution can be fully utilized to cover the areas without high traffic. Thus, the BTS capacity are well shared by nearby repeater sites. Normally, sites for repeater will be targeted and deploying at rural area, highway, island, low intensity residential and industrial area. Various types of repeater shall be carefully selected and recommended, to adapt its suitability respectively and reaching maximum cost saving to operator.
