wibro 대 HSDPA

WiBro (Wireless Broadband, Korean: 와이브로) is a wireless broadband Internet technology being developed by the Korean telecoms industry. It adapts TDD for duplexing, OFDMA for multiple access and 8.75MHz as a channel bandwidth.

WiBro was devised to overcome the speed limitation of mobile phone and to add mobility to broadband Internet. In February 2002, the Korean government allocated 100 MHz of electromagnetic spectrum in the 2.3 - 2.4 GHz band, and in late 2004 WiBro Phase 1 was standardized by the TTA of Korea and in late 2005 ITU reflected WiBro as IEEE 802.16e (mobile WiMAX).

WiBro is the service name for mobile WiMAX in Korea. Two Korean Telco (KT, SKT) launched commercial service in June 2006, and the tariff is around 30 US$.

High-Speed Downlink Packet Access (HSDPA) (Sometimes known as High-Speed Downlink Protocol Access) is a 3G mobile telephony protocol in the HSPA family, which provides a roadmap for UMTS-based networks to increase their data transfer speeds and capacity. Current HSDPA deployments now support 1.8 Mbit/s, 3.6 Mbit/s, 7.2 Mbit/s and 14.4 Mbit/s in downlink.

수도권은 고속으로 와이브로(다운로드 Max 40Mbps, 시속 60km의 속도), 전국적으로는 쇼를 하는 HSDPA(다운로두 Max 3.5Mbps, 이동 속도 시속 250km) 가 가능할테니
