OVERVIEW INTRODUCTION TOPOLOGY SIMULATION RESULTS SUMMARY REFERENCES 2
INTRODUCTION GOAL Compare performance of the leading 4G technologies, WiMAX and LTE for mobile users by the speed and quality of watching a HQ Movie MOTIVATION LTE gained more support even though both LTE and WiMAX are both 4G Technology. Determine the strength and weakness of WiMAX and LTE TOOL OPNET 16.0 will be used to simulate the scenarios 3
INTRODUCTION BASIC INFO WHAT is LTE Exactly? Shortened for Long-Term Evolution Standard for wireless communication with new DSP Technologies Use OFDMA for downlink, SC-FDMA for uplink WHO? Proposed by NTT DoCoMo in 2004 Documented and Standardized by 3GPP WHEN? Release 8 standardized by 3GPP in Dec 2008 4
INTRODUCTION BASIC INFO LTE STATS Download speed up to 326.4 Mb/s Upload speed up to 86.4 Mb/s Bandwidth of 20 MHz 5
INTRODUCTION BASIC INFO LTE COMPONENTS IN OUR TOPOLOGY User Equipment (UE) Evolved Node B (enb) Evolved Packet Core (EPC) 6
INTRODUCTION BASIC INFO LTE COMPONENTS Cont d User Equipment (UE) Clients, connected wirelessly to enb Creates a bearer when connection established with EPC Bearer A term to describe how UE data transfer across the network 7
INTRODUCTION BASIC INFO LTE COMPONENTS Cont d Evolved Node B (enb) Connected to UE and EPC Admission Control Determine if Guaranteed Bit Rate (GBR) and allocate available resources 8
INTRODUCTION BASIC INFO LTE COMPONENTS Cont d Evolved Packet Core (EPC) Create, Activate, and Manage the bearer created when connection established with UE MME and Session Management functions 9
INTRODUCTION BASIC INFO WiMAX Worldwide Interoperability for Microwave Access Uplink and Downlink both utilize Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme. A radio sector theoretical aggregate mobile speed of up to 70 Mb/s (up to 1Gb/s for fixed stations with recent updates) Bit error rate (BER) increases with distance thus significantly reducing bit rate at larger distances (maximum range of 50km) Can be used for broadband connections, cellular backhaul, hotspots etc. Inherently supports technologies such as Quality of Service (QoS) and Multicasting that make triple-play service offerings possible. 10
INTRODUCTION BASIC INFO WiMAX Components Base Station (BS) Send/Receive signal from cloud and send/receive it to the subscriber station Allocate bandwidth, control Quality of Service Subscriber Station (SS) Send/Receive signal from Base Station and send/receive to clients through WLAN or Ethernet connection Known as Client in our Topology 11
