IP以太网：未来霸主十兆、百兆到千兆和万兆,甚至40G的技术已经开始实验,IP以太网技术自1996年“信仰之争”后,以超越摩尔定律的发展速度迅猛发展,在经过了30多年的技术发展之后,再也没有任何人怀疑今后网络发展的主流是IP以太网技术。在IP以太网技术中,100BaseT是一个里程碑,确立了以太网技术在桌面的统治地位。千兆以太网以及随后出现的万兆以太网标准是两个比较重要的标准,以太网技术通过过这两个标准更是将IP以太网技术从桌面的局域网技术延伸到校园网以及城域网的汇聚和骨干。又要低功耗!谁能做到？八仙过海之无线3G：好事多磨作为第三代无线移动通信技术,3G能够处理多种媒体形式,提供包括网页浏览、电话会议、电了商务等多种信息服务。从上世纪90年代出现开始,3G技术就一直牵动着整个业界的发展。2000年5月,国际电信联盟(ITU)确定了w-CDMA、CDMA2000和TDS-CDMA三大主流无线接口标准；2000年左右,3G实验网开始在全球进行铺设；2004年,以爱立信、NEC等企业在3GWCDMA标准基础上扩展的HSDPA技术更是将3G技术标准的上传、下载性能指标提升很多倍、如今,3G终端、商用模式、运营经验等均取得了长足发展,但对于3G还只能是等待、再等待……WLAN：只是减去一条线缆曾被喻为推动下一代例络通信的最大推动力的WLAN,从最初与HomeRF、红外、蓝牙等技术的竞争,接着是基于802.11的各种标准之争,再后来是中国无线安全标准WAPI让全球沸沸扬扬……如今,WLAN在辗转运营商、行
IP Ethernet: Future overlord ten trillion, Gigabit to Gigabit and 10 Gigabit, or even 40G technology has begun to experiment, IP Ethernet technology since the 1996 “dispute of faith” to move beyond the rapid development of Moore’s Law, After more than 30 years of technological development, no one doubts the mainstream of future network development is IP Ethernet technology. In IP Ethernet technology, 100BaseT is a milestone, establishing the dominance of Ethernet technology on the desktop. Gigabit Ethernet and the ensuing 10 Gigabit Ethernet standards are two of the more important standards, Ethernet technology through these two standards is the IP Ethernet technology from the desktop LAN technology extends to the campus network and the metropolitan area network The convergence and backbone. But also low power consumption! Who can do it? Eight Immortals wireless 3G: Good things and more grinding As the third generation of wireless mobile communication technology, 3G can handle a variety of media forms, including web browsing, conference calls, electricity and other business information services. From the 90s of last century appeared, 3G technology has been affecting the development of the entire industry. May 2000, the International Telecommunication Union (ITU) identified the three mainstream w-CDMA, CDMA2000 and TDS-CDMA wireless interface standards; around 2000, 3G experimental network began laying the world; in 2004, Ericsson, NEC, etc. Enterprises in the 3GWCDMA standard based on the expansion of HSDPA technology is the 3G technology standard upload, download performance index to enhance many times, and now, 3G terminals, business models, operating experience have made great strides, but for 3G can only be Waiting, Waiting ... WLAN: Just minus a cable WLAN has been hailed as the biggest driver of next-gen intercom communications from initial competition with HomeRF, Infrared, Bluetooth and other technologies, followed by 802.11 The standard dispute, then the Chinese wireless security standard WAPI to make the world an uproar ... ... Now, WLAN operators removed in the line
