Vick Khalil Mamlouk – VP Sales Middle East and Africa May The Future of Cellular

2 PRIVATE AND CONFIDENTIAL © 2011 CommScope, Inc The Goal The goal of the Future State Working Group was to answer the following two questions: In the year 2015 how is cellular service delivered? What strategies should the business units take to maximize our market share in 2015? Participants Wireless business unit GMs, wireless sales, and designated “thought leaders” within product management and R&D

4 PRIVATE AND CONFIDENTIAL © 2011 CommScope, Inc Our Conclusions Areas of Consensus – The Highlights Heterogeneous Networks. The “HETnet” The concept, among other things, of a coverage network and a capacity network Multiprotocol/Multi-frequency Operator’s focus will be on increasing the efficiency/utilization of their spectrum by various means (sector splitting, MIMO, etc.) DAS, given it’s ability to be multi-vendor/multi-frequency will continue to be a viable coverage/capacity solution Even in light of wide spread remote radio head adoption

5 PRIVATE AND CONFIDENTIAL © 2011 CommScope, Inc Areas of Contention Where No Consensus was Reached The extent of using to offload data from the cellular network The extent of like-for-like upgrade of cellular networks, i.e. the Sprint CDMA upgrade The speed of LTE adoption/deployments How many WCDMA operators will shift to or add LTE services?

8 PRIVATE AND CONFIDENTIAL © 2011 CommScope, Inc Heterogeneous Networks Adding Indoor Coverage

9 PRIVATE AND CONFIDENTIAL © 2011 CommScope, Inc Heterogeneous Networks (the HETnet) The main idea is that operators will need to deploy two networks A Coverage Network that provides wide area and mobility access A Capacity Network that provides increased capacity in data hotspots, i.e. airports, train stations, sport and concert venues, and large enterprises It may be that operators deploy these two networks at different frequencies so as to mitigate interference issues The capacity network will be provided by a varied topology of access solutions such as remote radio heads, micro and pico base stations, femtos, and DAS products Andrew Solutions is a leader in DAS but there will be large opportunity for new solutions

15 PRIVATE AND CONFIDENTIAL © 2011 CommScope, Inc 2015 will have large networks supplying all three generations of wireless technology We do not see 2G or 3G networks being turned off until well past 2015 In order to support the introduction of 4G, new frequency bands will be deployed In addition, in many cases there will be multiple protocols in each band Given this development, the increasing complexity of the cell site will become a major problem. Across all wireless business units we need to increase our capability to provide multiband/multiprotocol solutions with reduced time to market We would be happy to present the entire set of findings at a later date Multi-Protocol/Multi-Frequency North America EMEA China India 700/850/1900/2100/2500MHz 800/900/1800/2100/2600MHz 700/800/900/1800/1900/2100/2600MHz 700/800/850/900/1800/1900/2100/2300MHz
