? . WiBro : Service Concept (cont’
(cont’d)
WLAN: High-speed Wireless Internet Service (IEEE 802.11 series)
• Wireless IP service in a local or private area
• Very high data rate up to 54Mbps
• But, limited coverage and poor QoS
Cellular: Medium or Low Speed Wireless Internet Services (cdma2000,
WCDMA)
• Public mobile service on Cellular-based platform
• Higher Infra cost
– Designed to provide voice and data simultaneously in
nationwide area.
• Lower data rate
– 144/384 Kbps (cdma2000 1x, WCDMA), 2.4/15Mbps (Ev-DO,
HSDPA)
• But, too expensive and limited data rate
