    • This invention is related to increasing the Quality of Service (QoS) and lowering Packet Loss Rate (PLR) by protecting high priority packets transmitted in a WLAN from hidden nodes that is often encountered in neighboring WLANs and 802.11s mesh networks by utilizing selective RTS/CTS signaling architecture. The WLAN devices developed in this invention send RTS signal and wait for CTS before sending high priority packets but do not send RTS for other packets which are lower priority. High priority packets are usually video or voice packets that require real time delivery with high QoS requirements and with very low PLR. By enabling RTS/CTS signaling only for high priority traffic, the total overhead caused by RTS/CTS signaling is minimized and the total network throughput capacity is optimized. Those devices can also transfer voice and video or like signals at high quality by forming IEEE 802.11s Standard compliant wireless mesh networks in order to overcome wireless signal attenuation problems encountered in concrete buildings. Every mesh point in 802.11s mesh network also implement selective RTS/CTS signaling in order to protect high priority packets throughout the mesh network. The devices invented may also include VoIP, IPTV or DSL modem features integrated in the same hardware utilizing different IEEE 802.11 standards including IEEE 802. Hg and IEEE 802.Hn.
    • 本发明涉及通过利用选择性的RTS / IP网络来保护在WLAN中传输的高优先级分组从经常在相邻WLAN和802.11网格网络中遇到的隐藏节点降低分组丢失率(PLR) CTS信令架构。 在本发明中开发的WLAN设备发送RTS信号,并在发送高优先级数据包之前等待CTS,但不对其它优先级较低的数据包发送RTS。 高优先级数据包通常是视频或语音数据包,需要具有高QoS要求和极低PLR的实时传送。 通过仅对高优先级业务启用RTS / CTS信令,RTS / CTS信令引起的总开销最小化,并且优化了总网络吞吐量。 这些设备还可以通过形成IEEE 802.11s标准兼容的无线网状网络来传输高质量的语音和视频或类似信号,以克服混凝土建筑物中遇到的无线信号衰减问题。 802.11s网状网络中的每个网格点还实现选择性的RTS / CTS信令,以便保护整个网状网络中的高优先级分组。 所发明的设备还可以包括集成在相同硬件中的VoIP,IPTV或DSL调制解调器功能,其使用不同的IEEE 802.11标准,包括IEEE802.HP和IEEE802.Hn。
