transmission speed.
it is aim that as a wire and wireless integrated,
enable to real multimedia communication.
4G mobile communication characteristic
transmission speed
when moved 1link per 100mbps
when standstill, it expeced up to 1Gbps
technology flexibility
various environment, various service
functional fusion
guaranteed interworking and interoperability.
using just one cellphone, it can use all service such as
WAN WLAN, internet
it is more faster about 10times and higher throughput than IMT-2000
three dimensions videophone
perfect global roaming
Development route of LTE, Wimax
LTE-Advanced : developed based on 3G celluar system
IEEE 802.16m WiMax : WiFi → fixed Wimax → Mobile Wimax
started as a WiFi`s function and scope extension
started as a wire and wireless internet service`s substitute and complement
strengthen mobility and developed mobile WiMax technology
called Wibro in Korea
