• Communication within organisations. Consider a university which has WiFi based Intranet
but no fixed landlines. Rather than using GSM handset for inter-office calls, VOIP over WiFi
can be used.
• Local call mesh network. Statistics show that 60% of all phone calls are local. A group of
villages several km apart could be linked by Wifi, and IP04s deployed to build a small local
"mesh" telephone network. Voice works for the illiterate, so IP04 deployment may actually
stimulate WiFi link roll out, which can then be used as a back bone for Internet connection and
web/text based services like email and chat. One end of the mesh could be connected to the
PSTN or GSM network.
13.8 Next Steps
We suggest one or more field trial deployments designed to test the hardware and business models.
The plan should include the following activities:
• Find sponsor: venture, donor or private philanthropist
• Identify general recipient requirements
• Identify training needs and local support
• Study the regulatory aspects
• Identify and manage risks
• Choose a site and identify who would benefit the most from telephony
• Design a production environment including the possibility of building the units locally.
• Develop a localized software version, focus on usability, e.g. ease of installation, ease of
maintenance.
• Develop local training materials
• Develop a business model and integrate it with the technology
• Field implementation and training including
○ Hardware assembling
○ VoIP networking
○ Energy support
○ Business models
• Involve the community
• Document the findings
