Research question
Current mesh network based on Wi-Fi Industrial, Scientific, Medical (ISM) 2400 MHz band High Rate/Short Range Sensitive from disturbances High consummation of the power
Implementation on ISM 915 MHz band Low Rate/Large Range Several national restrictions
Is it possible to create an Ad-Hoc packet radio network within the regulatory restrictions
imposed on the ISM-915 MHz band in Australia and the United States of America?
Serval Project : Communicate anywhere, anytime
7
Key points Ad-hoc packet radio frequency
Using the ISM-915 MHz band (915-928 MHz) Temporal-Frequency hopping : Synchronization
Low-cost Radio modules
Serval Project : Communicate anywhere, anytime
8
Key points
Integrate with Serval Mesh Through the Serval BatPhone
Optimize the bandwidth efficiency Scarce resource Range/Capacity Packet Loss
Serval Project : Communicate anywhere, anytime

Conclusion
Future works Total Integration in the android-based application Using the mobile phone’s antenna
Not require the low-cost radio module Reprogramming of the mobile phone’s firmware
Switching capacity on the application Wi-fi 915 MHz 915 MHz Wi-fi
