4G-readiness The state of play of a country s mobile wireless status and the ability of its consumers, businesses and governments to use in the future the mobile wireless to their benefit 57% Description of the contents
Other similar studies E-readiness, is the measure of a country s ability to leverage digital channels for communication, commerce and government in order to further economic and social development E-government facilitate communication and improve the coordination of authorities at different tiers of government, within organizations and even at the departmental level.

In-building coverage challenges Eco-friendly Shield against the heat buildings Unreliability Weak or signal loss between the floors Poor services Dual-mode phone adds complexity and cost No seamless support
Mobile operators needs Increased customer loyalty and QoE Simple low cost solutions Increase ARPU Help the adoption of new technologies and services
Solution: Femtocell or home base station The main objective behind a femtocell is to provide high quality indoor xg coverage. The cell itself plugs into a regular broadband connection but enables you to surf at high speeds via your mobile phone's browser. Source: The case for Home Base Stations, Technical paper, picochip, 2007
First commercial case.. Softbank in Japan ZAPs (Zonegate Access Points). Protocol (SIP) with 'Presence to price 3G calls differently based on location. The IMS femto can mediate better data service to existing 3G handsets, so it lets Softbank sell more data services
Case study Population density of 10000 persons/sq.km Medium size city Use of 5G compliant femtocells Support of multimedia services such as video streaming 2 users per femtocell
Benefits Macro-cells savings, less CAPEX Better seamless coverage home and office Reduced churn Easy deployment Low-power indoor cellular access points compatible with UMA Source: UMA and Femtocells: Making FMC happen, P CHOUDHURY, D DAHUJA, 2007
Future directions and conclusions What is the best dual mode or femtocell? UMA and femtocell as frontier? The economics are complex especially on monthly charges Many diverse solutions serve different scope Each operator has different strategy that should converge in the future
