10. Sizang Village Telco -
Goals
Goals
● Train Sizang Community to install a
Village Telco network
● Install at least 10 Mesh Potatoes(within 5
villages)
● Build a local call telephone network
● Build an IP Backbone for local IP traffic
11. Project Plan
● A ki cian om ngol lai...
● Sizang World Wide Communites te tawh
na sep khop thei na nei zo nuam..
12. ● Education
● Health care(Telemedicine)
● Communication(Email/Intranet/Internet)
● Local Business
● Access to news and Information
● And many more....
13. Sizang Village Telco
● Main goal is local telephone calls
● IP connectivity across Sizang Villages
● Public IP backbone across Sizang Villages
● Public resource, e.g. local chat, web
servers, Wiki, mirror of web content
● Internet can be distributed by this
network(via Kalaymyo IPSTAR or DSL)
● But this project doesn't provide Internet
14. Risks
● What can go wrong?
● What happens when the trainers goes
home?
● Train Sizang Community to fix problems
● Focus on keeping network running
● Train many people, not just one expert
● Sustainable Strategy/plan(a diak diak Community
based projects na sep na ah...)
● How can we make it more reliable?
Do we need special licence for 2.4 and 5.0 Ghz
frequency bands in Burma?
15. Bang Van teng ki sam/zang tu?
● Inndoor Access Point Router (Or)
● Outdoor Access Point
Router(incl.Antenna)

20. Antenna
●2.4Ghz Square Grid Parabolic
Antenna, 24DBI – 50 US $
But with modern Outdoor Access
Point Router with integrated antenna,
you dont need those Parabolic
Antenna anymore.!!!
OMNI-DIRECTIONAL - 360°
21. The Mesh Potato
● The Mesh Potato is a new device for providing low-cost telephony and
Internet in areas where alternative access either doesn’t exist or is too
expensive. It is a marriage of a low-cost wireless access point ( AP)
capable of running a mesh networking protocol with an Analog Telephony
Adapter (ATA).
Wireless Router 2 dbi Antenna + Telephone a ki hel Device no khat hi.
60 – 100 $ man.
22. Khau 2 ki zom na tu.
Phone bek hi x hi..
● 2 Mesh Potato (180 US $) :-( ha, man ham thong
● 2 Outdoor AP – 100 US $
● Cables – 15 US $
● 2 Analog Telephone – 30 US $
plus logistics costs
totals → 325 US $
Phone call + Data network for many
purposes
