6. Situation 1. Every site has unique BOM since it might has different parameters: – Number of links Related to indoor unit type that will be used: 2/5/20 slots. – Link specifications: Antenna diameter size: 1/2/4/6 feet Antenna type: Std (Standard)/HP (High Power) Radio Frequency: 11/15/23/28/38 GHz Radio modulation: 4/16/64/126/256/512 QAM Capacity: 30/60/125/200/350 Mbps Link specification example: – 15GHz 064T/16 ANT0.6 HP (not all sites has the same spec!) – Antenna placement location Antenna location: rooftop or tower Related to radio cable size that will be used. Cable length size: 1 - 400 feet

7. Situation 2. Total number of sites: 6000 sites nationwide. 3. BOM must have accuracy with maximum error tolerance 1% 4. Timeline: 2 months 5. Maximum number of resources 2 engineers.

8. Situation Description Site Link Even though these two sites have same condition (they have 2 links), it does not mean the BOM will be same. The link spec might be different so is the antenna location. -One site can have high tower and the other site can be roof top. -One link can have MLTN28/2X 194T/64X-140 spec and the other can have 2010 28 064T/16-20 spec.

11. Problems Huge effort to finish the work with limited resources. – Rough Calculation: 6000 : 2 engineer = 3000 sites/2 month/engineer = 65 sites/day/engineer – Supposed 1 engineer can finish 1 site BOM within 15 minutes with 8 working hours per day, it will take 4 months to complete the work. Human error probability is high for repetition work. Difficulties to track the document if there are some changes or revision during BOM generation process.

12. Solution BOM generator automation is needed to produce the BOM faster, less errors, more accurate, consistent, easy to track, and convenient for all end users.

13. Implementation Aspects In order to create this automation, a programmer with competence in.NET and C# language, SQL database, and web programming is needed. The programmer resource will be taken from internship since the project duration is only 1-2 months. The programmer must collaborate with Subject Matter Expert (SME) to produce the correct algorithm for all automation processes.

14. Cost Estimation and Comparison Up to 85% cost reduction! vs

15. SUMMARY Engineering team had to deliver BOM for sales and project team based on solution requirement and final design output. After analyzing all possible risks, we found 3 major problems that must be handled. BOM generator automation is proposed as a solution for the problems. Based on rough cost estimation, the tool is not only will speed up the process but it can reduce the operational cost up to 85% as well.
