无线局域网TCP技术

无线通信和因特网的结合无疑是未来发展的趋势.Internet中的TCp协议提供端到端可靠的服务,可以为多媒体业务的传输提供Qos保证,广泛应用于支持如FTP、Telnet、Http等Internet业务.TCP最初是针对有线信道特性设计的,有线信道中的传输性能相对较好,可以认为网络拥塞是影响Qos的唯一原因,因此其TCP协议都是据此进行拥塞控制和流量控制的.而无线信道的特性,如多径衰落、干扰、频谱有限等使得当传统的有线TCP协议应用于无线链路时性能严重降低.

TCP Wireless LAN Technology

Wireless communications and the Internet is the future with the development trend.Internet TCP protocol provides reliable end-to-end services,multimedia services can provide QoS guarantees transmission is widely used in support such as FTP,Telnet,HTTP and Internet business.TCP was originally aimed at the design of cable channel,cable channel transmission performance is relatively good,network congestion that can affect QoS is the only reason,therefore this is a TCP Congestion Control and Flow Control.The channel features such as multipath fading,interference,and makes limited spectrum when the traditional wired TCP performance when used in wireless serious decline.
