LTE | WiMax | |
What | • An All-IP radio technology that increases the capacity of mobile telecommunication networks • 3GPP Standard • 115 Mbps speed • Mobility rate of 350 km/hr | • Primarily a replacement for last-mile wired broadband technologies (DSL & Cable) • IEEE Standard • 10 Mbps speed • Mobility of 120 km/hr |
Why | Data intensive mobile applications (such as online videos) and mobile devices (such as iPhones & Blackberrys) trigger the need for LTE | Need for providing Internet access to places where laying fiber cables is not technically/economically feasible (such as rural areas) |
How | • Uses multi-layer antenna solution to achieve high data rates (MIMO ) • Uses OFDMA & SCFDMA for air interfaces | • Uses dynamic burst algorithm modulation adaptive to the physical environment the RF signal travels through • Uses OFDMA & SOFDMA for air interface |
Where | Majority of the trials & deployments are happening in the developing countries (Korea, Malaysia, Singapore, Mexico etc.,) | |
When | Commercial deployments expected to happen in 2010 | Commercial deployments are happening in several places, already |
