Flash OFDM network efficiency
Jireček, Martin ; Mikulka, Jan (referee) ; Hanus, Stanislav (advisor)
The FLASH-OFDM networks (Fast Low-latency Access with Seamless Handoff-Orthogonal Frequency-Division Multiplexing) are insert to network of fourth generations. The system are set to fast data transfer. These networks have lower latency than network of third generations. On average is transmission speed for downlink cca 1,5Mb/s and for uplink cca 300-500kb/s. In connection with progress of high-speed network and systems with finite mobility (Bluetooth, IEEE 802.11), creationed want of new standard, which connect both merits. For WiMAX was defined new basic requirements: • mobility of user, • high-speed data transfer with roaming, • the lest latency of systém using aplications in real time, • high count of at the same time communication users in cell, • chance of better control QoS (Quality of Service).
