Bangladeshi villagers sharing cell phones helped build what is now a thriving company with more than $200 million in annual profits. But what is the lesson for the rest of the world? This is a question author Nicholas P. Sullivan addresses in his tale of a new kind of entrepreneur, Iqbal Quadir, the visionary and catalyst behind the creation of GrameenPhone in Bangladesh. GrameenPhone& a partnership between Norway's Telenor and Grameen Bank, co-winner of the 2006 Nobel Peace Prize& defines a new approach to building business opportunities in the developing world. You Can Hear Me Now offers a compelling account of what Sullivan calls the "external combustion engine"& a combination of forces that is sparking economic growth and lifting people out of poverty in countries long dominated by aid-dependent governments. The "engine" comprises three forces: information technology, imported by native entrepreneurs trained in the West, backed by foreign investors.

In this work, coherent techniques for time difference of arrival estimation for frequency hopping GSM signals are introduced. The techniques provide significant improvements in accuracy compared to state-of-the-art techniques and are ideally suited for highly accurate localization of GSM mobile phones. The key inventive concept is based on the interpretation of a frequency hopping GSM signal as a wideband signal. Thus, the applicable bandwidth for time difference of arrival estimation can be increased from 200 kHz for the narrowband burst signal to the full uplink bandwidth of the corresponding GSM standard. For E-GSM 900 systems, up to 35 MHz of bandwidth can be employed. Consequently, a localization accuracy in the scale of 5 - 10m is achievable. The presented coherent techniques for time difference of arrival estimation permit novel applications with increased accuracy requirements such as highly accurate localization in search and rescue scenarios. Furthermore, the coherent estimation concept can also be adapted to any frequency hopping signal source such as TETRA, DECT, IEEE 802.15.4 (ZigBee) and IEEE 802.15.1 (Bluetooth) devices.
