Additional information where our Partner should fulfill it

1. Photos of existing BTS (actual condition) like as configuration 2G BTS (if it can) or detail condition

2. Location of 2G BTS and propose new location for 3G Node B

3. Drawing existing configuration (cabling from top of BTS until first of component)

4. Amount of existing component

5. Drawing for propose 2G co located with 3G

6. Any component that we needed for Telecom Implementation
