Q&A

Need for Rural connectivity We are more dependent on the

Internet for communication, information, health services, education, disaster management and business relations

Internet has to be seen as Basic Human Right in days to come

out of 7.2 billion world population, only 3.3 billion population is connected through internet

Out of 3.9 billion unconnected internet population 800million population is from INDIA – ideal case for make in INDIA and for INDIA

“10% increase in internet penetration can boost GDP by 1.4%”: ITU

Need for Rural connectivity

Connectivity is a MUST for rural area to manage limited resources and utilize them in a efficient way like power, irrigation etc.

Improves education and health services in rural area

E-commerce platform to connect end buyers to farmer – eliminating middle men

Characteristics of different WRAN standards

Requirement for Rural Broadband

Entry Cost – Low like Wi-Fi

Range – at least 15-20Kms

Deployment time and Scalability – like Wi-Fi

Network Latency - <50msec

Speed per user – At least 1Mbps to have video call

Network Topology – WRAN

What/Where is TVWS

TV Whitespace(TVWS) are unused gaps in TV broadcast spectrum (470-690MHz)

Where

TVWS Policy in place

USA, UK, Philippines, Singapore, Korea, South Africa

Under consideration/Trials

India, Indonesia, Vietnam, Japan

Malawi, Kenya, Botswana

Brazil, Argentina, Columbia

Kazakhstan

Why TVWS

Better Coverage than Wi-Fi • FSPL(dB)=20log10(d)+20log10(f)+

92.45 • FSPL free space path loss • d distance in KMs • f frequency in GHz

Long range with low power • Fewer towers Lower Capex • Runs off solar power Lower

Opex • Ideal for low user density areas

Better Non-Line-of-Sight (NLOS) Performance

Spectrum allocation in TVWS Band

TVWS Band allocation by taking existing licensed use Offer the promise of opportunistic access to under-utilized

frequency bands Location-aware wireless BS/CPE devices, assisted by

databases for band allocation
