You're on a bus traveling at 70mph. You need to maintain a constant wireless connection of 100Mbps, or your boss's presentation will be ruined. What do you do, hot shot? What do you do?
Well, if you were in Jeju Island, Korea yesterday, you could have hopped on board a specially designed bus at Samsung's 4G Forum, in which the company presented the world premier of 4G WiBro (Wireless Broadband) technology. Granted, the bus was traveling at around 60kmph (or about 37mph).
The bus stunt was an effort to prove the stability of 4G technology by demonstrating a multi-cell handover with data speeds of 100Mbps, simultaneously offering delegates a live broadcast of the forum, Internet access, and video on demand, according to Samsung.
Additionally, the company showed off 4G's nomadic speed of 1Gbps data transmissions inside the forum venue with simultaneous 32HD channel broadcast (20Mpbs) downloads, Internet access, and video telephony. Furthermore, a 3.5Gbps data transfer demonstration using 8x8 MIMO (multi-input multi-output) was part of the display.
A speedy cousin to WiMax, WiBro's nomadic speed of 1Gbps is 50 times faster than 3G, according to Samsung. With speeds of 1Gpbs, it would take about 2.4 seconds to transfer 100 MP3 files (300MB), and 5.6 seconds to transfer one 800MB movie.
Samsung isn't the only company eyeing the next generation of wireless networking. Sprint this month declared its intent to unfurl a WiMax-based 4G mobile network by next year. Notably, Samsung as well as Intel and Motoral are partnering with Sprint, equipping notebook PCs and a variety of mobile devices to use the 4G network.
Additionally, NTT DoCoMo reported last February achieving data transmission speeds of 2.5Gbps in 4G field trials.
WiBro is based on the IEEE 802.16.e-2005 standard. The 4G mobile communications format is expected to become commercially available around 2010. Samsung already holds more than 220 patents related to 4G mobile communications.
The spectrums for 4G technology will be decided at WRC (World Radiocommunication Conference) in October of 2007.
