ALL RIGHTS RESERVED. 3 The Benefits of Wireless Broadband Social and Economic Benefits Currently, “there are over 6 billion mobile phone subscribers, 75% of the world’s population has access to a mobile phone, more than have access to a bank account, electricity or even clean water.” (World Bank 2012) ­ Developing countries are “more mobile” than developed, and are developing unique applications and services to empower local economies. ­ The world is increasingly “flat,” with the world’s information available to all. ­ Broadband growing faster in developing countries with over a 200% growth rate. A 2008 Deloitte & Touche study found that the mobile industry in 6 countries was responsible for 3.7% to 6.2% growth in GDP and 0.2% to 1.1% growth in employment A study by McKinsey & Company on Latin American countries stated that the combined GDP could increase by up to $70 billion, and add up to 1.7 million more jobs Enriching & Developing people with access to “Symmetrical information”

Particularly challenging for Public Safety (PS) with noise limited long-range systems on high towers. Only the worst cases of interference are highlighted.

Without careful coordination, US Public Safety interference is more problematic. PS Terminals will cause interference to APT-700 terminals at high frequency end.  There is much more downlink traffic than uplink.  The benefits of mobile broadband are enormous, and fun!
