Mobile traffic skyrocketing Mobile internet in 2010 is bigger than whole internet in 2000 AT&T 2Q06-2Q09 5000% growth Ericsson 2Q09-2Q10 3X Cisco MVNI 108% CAGR 100% CAGR = 1000X growth in ten years Nasdaq: MSPD
Devices Have Forever Changed 5KB/month 5MB/month Smartphone GSM 3G analog tablet netbook 5GB/month laptop micro minimainframe Nasdaq: MSPD
Throughput Density: A Problem To Resolve 2G networks for voice are rarely overloaded, mainly a coverage game A Macrocell can deliver the service to hundreds of users with expected quality of services 3G applications start to show the impact of highly capable UE taking away available throughput, e.g., iPhone, iPad China Mobile doubled their 2G/2.75G BTS in two years to support data on EDGE ATT ended their unlimited data plan for the iPad less than Mobile Device Throughput Capability the 1 month into the launch of first iPad 100000 20000 UE capability is exponentially increasing 10000 2000 1000 384 A future LTE UE can perfectly take the 128 Kb/s 100 entire throughput capacity of a cell-site 13 10 4G networks will have to address the 1 throughput density issue 2G GSM 2.5G GPRS 2.75G EDGE W-CDMA LTE A Macrocell capacity of 150Mb/s can not satisfy the need ofthroughput to Delivering hundreds of users users is the mission of LTE Two key ingredients: coverage and throughput density 5Nasdaq: MSPD
Wireless Broadband Usage Survey Industry consensus is that indoor coverage will be a crucial issue for wireless broadband 6Nasdaq: MSPD
DAS: Current Solution For Indoor CoverageDistributed Antenna Systems (DAS): Take a Macrocell baseband module (BBU) Use remote radio-head (RRH) at each floor Distribute analog antenna signal from the RRH to multiple low power radio-headsPros: Simple, effective to improve coverage Coexist well with Macrocell No hand-over issue from a radio-head to anotherCons: No throughput capacity improvement Radio-head malfunction not easily detectable Deployment requires power adjustment at each China China China radio-head, only viable for public buildings or Unicom Mobile Telecom enterprises Very expensive 7Nasdaq: MSPD
Comparison of Indoor Coverage Solutions Key User Experience DAS WiFi Smallcell Metrics Coverage Yes Yes Yes Throughput improvement No Yes Yes Mobility Yes No Yes QoS/QoE Yes No Yes Key Operator DAS WiFi Smallcell Concerns Deployment cost High Low Mid Operating cost High Low Low Capacity enhancement Difficult Easy Easy Future evolution Difficult None Good Control Yes No Yes Coexistence with Macro Yes Yes Challenging 8Nasdaq: MSPD
Typical LTE Deployment Scenarios Phase-1: Macrocell based network build-outs (2010-2013) Reuse current cell-sites and infrastructure like fiber networks Phase-2a: Microcell/Pico to fill-in the coverage blind spots (2012-2014) New cell-sites and subsequent infrastructure are main concerns Phase-2b: Enterprise Pico/Femto to provide in-door coverage (2012-2015) Interface with Enterprise Intranet yet under operator’s control is a major unresolved issue Deployment scenarios and cost are also major issues Phase-3: Femto to address coverage at home (2012-2016) A major problem is backhaul Operators with high speed wireline will have a huge advantage Mindspeed Transcede solutions target Phase-2/3 deployments 9Nasdaq: MSPD
Challenges and Opportunities Wireless broadband is taking off Demand for throughput density, as well the need for indoor coverage, will force the use of small cell solutions Off-loading traffic from macro cell as much as possible Co-existence of LTE with 2G/3G requires SW upgradable dual-mode eNBs Small cells require low power and low cost Single chip SoC is the only viable solution In-door coverage requires low cost, easily deployable solutions yet manageable by operators Operators claim that they spend 3.5-4h technician’s time at $50/h rate for each customer home gateway installation Not only cost CAPEX, but also limit the rate of large scale deployment PoE is a key for Enterprise (no power line means no need for licensed technicians for installation) 11Nasdaq: MSPD
