Close · a way forward
(A) Working principle
| Optical | Satellite |
|---|---|
| (1) Based on Total Internal Reflection | (1) Mirroring of signal by satellite |
| (2) use of light as source | (2) use of microwave as source |
| (3) ground based system | (3) ground and space based system |
(B) Accessibility
| Optical | Satellite |
|---|---|
| (1) More accessible in city (crowded area) | (1) Lower speeds in crowded areas |
| (2) costly for rural (low crowd area) | (2) potential to provide last mile delivery |
(C) Scalability
| Optical | Satellite |
|---|---|
| (1) Scalable across globe e.g. SLOC cables | (1) Same e.g. Starlink project |
| (2) High infrastructure cost | (2) Lower cost of delivery of internet |
| (3) Susceptible to local damage | (3) More resilient and long lasting |
(D) Limitation
| Optical | Satellite |
|---|---|
| (1) Last Mile Delivery is challenge | (1) Latency vis a vis optical is high |
| (2) High per gb transmission cost | (2) Lower speed compared to optical |
Both together would help in providing last mile connectivity as envisioned under Bharat Net
