KOMRAD The Compact Open Mobile Reference Architecture and Design Rajiv Poddar [email_address]

What is KOMRAD? Blueprint for mobile phones Reference Design for Mobile Phones Software and Hardware Derived completely out of Open Source Software and Open Hardware Commercial Off The Shelf Solutions

Blueprint for mobile phones

Reference Design for Mobile Phones

Software and Hardware

Derived completely out of Open Source Software and Open Hardware

Commercial Off The Shelf Solutions

Why is it needed? 80 % of the World’s population are covered by a Wireless Network Only 25 % amongst them own a mobile phone Multiple barriers to entry Cost of the handset Total Cost of Ownership Source: GSM Association

80 % of the World’s population are covered by a Wireless Network

Only 25 % amongst them own a mobile phone

Multiple barriers to entry

Cost of the handset

Total Cost of Ownership

How does KOMRAD help? Focuses on the technical barrier to entry Makes mobile phone as easy to assemble as a computer Enables communities to build their own solution Disrupts the value chain of the mobile phone market
