There are several LAN (Local Area Network) technology that can link up communication devices in home networking such as wireless 802.11 a/b/g, Homeplug AV, MoCA (Multimedia Over Coaxial cable) and more.

Among these technologies, the most well known one would be 802.11 a/b/g wireless technology that doesn¡¯t require cable and capable of handling high bandwidth.

Besides 802.11 wireless technology, some of us may not aware that there is another type of wireless technology known as UWB (Ultra Wide Band) which could support even higher throughput of up to 100 Mbps for wireless streaming in digital home. 802.11 ¹«¼± ±â¼ú °Ô´Ù°¡, ¿ì¸® Áß ÀϺΰ¡ ÀÌ¹Ì ¹«¼± ±â¼úÀº UWB (¿ïÆ®¶ó ¿ÍÀÌµå ¹êµå)·Î ¾Ë·ÁÁøÀÇ ¹«¼± ½ºÆ®¸®¹ÖÀ»À§ÇÑ µðÁöÅРȨ¿¡¼ ÃÖ´ë 100 MBps 100ÀÇ ´õ ³ôÀº 󸮷®À» Áö¿øÇÏ´Â ¼öÀÖ´Â ´Ù¸¥ Á¾·ùÀÇ ÀνÄÇÏÁö ¸øÇÒ ¼öµµÀÖ½À´Ï´Ù.
As the name mentioned, Ultra Wide Band operates in a very wide spectral range from 3.1GHz up to 10.6 GHz.

The bandwidth is about 80 times wider as compared to 802.11 which stay around 17 MHz. 17 MHzÀÇ ´ë¿ªÆøÀ» ¾à 80 ¹è ÁÖÀ§¿¡ ¸Ó¹°¿¡ ºñÇØ 802.11·Î ³ÐÀºÀÔ´Ï´Ù. In terms of power transmission, UWB has very low transmit power of about 0.1 mW, which is far lesser than 50mW required on 802.11 technologies. µ¿·Â Àü´ÞÀÇ °üÁ¡¿¡¼ º¸¸é, UWB´Â ¸Å¿ì ³·ÀºÀº 50mWº¸´Ù ÈξÀ ´ú 802.11¿¡ ÇÊ¿äÇÑ ±â¼ú¿¡ ´ëÇØ 0.1 mW±îÁö, ¼ÛÀüÇϰíÀÖ´Ù.
With such a low transmit power, UWB has advantage over 802.11 in extending battery life of communication devices, while it doesn¡¯t compromise in the range that it can reach. ³·Àº Àü·Â ¼Ò¸ð¿Í Àü¼Û µî ¾Ê´Â ¹üÀ§¿¡¼ ŸÇùÇÏ¸é¼ ±×°Í¿¡ µµ´ÞÇÒ ¼ö 802.11 ÀÌ»óÀÇ UWB Åë½Å ±â±âÀÇ ¹èÅ͸® ¼ö¸í ¿¬Àå¿¡ ÀÌ¿ëÇϰíÀÖ´Ù.
