  1. Development of Low Cost Synchronization Oscillators for Stand Alone Networks for Efficient Broadcasting in the Geographically Challenging Locations of India A pilot project funded by Ministry of Human Resource Development Under the Scheme on “National Mission on Education through Information and Technology” Project PI: Dr. K. S. Daya Microwave Physics Laboratory Department of physics & Computer Science Dayalbagh Educational Institute Dayalbagh, Agra –282 110 Project website: www.mwpl-dei.com

  2. Objective for the Pilot Phase Design of Temperature Stable Dielectric Resonator which is the basic building block for a stable Oscillator Stand-Alone networks are autonomous network stations with every node having the complete functionality of a traditional network but without the hierarchy for the information traffic flow. Unique feature of local information routing makes these systems capable of substantially reducing the network roll-out cost and turning it into a viable option for isolated regions with low demographic density with very low operational cost Specifications of the Dielectric Oscillator at every client: High Dielectric Constant (for compact size) Major Drawback These systems do not have reference clock for synchronization, coming from the server in a traditional network. High quality factor (for accuracy in frequency selection) Temperature stable from -50C to 550 C and slow thermal aging Stability of < 20ppm
