摘要： A local area network is provided where an OFDM station and DSSS/CCK station coexist. During a contention-free period both stations operate under the point coordination function rules as defined in the IEEE 802.11 specification. Both stations transmit data when polled by the access point. The contention-free period comprises a sub-contention period during which only the OFDM station communicate. During the sub-contention period the OFDM station operates under the distributed coordination function while the DSSS/CCK station waits to be polled by the access point before starting to communicate.

摘要： A local-area network is provided where a plurality of OFDM stations and DSSS/CCK-only stations coexist. A beacon signal having a contention-free-period (CFP) is transmitted from an access point to the plurality of stations. The OFDM-modulated data is transmitted to the plurality of stations before the CFP ends, and after the CFP period ends, the DSSS/CCK-modulated data is transmitted, thereby preventing collisions between the stations.
摘要翻译：提供了一个局域网，其中多个OFDM站和仅DSSS /仅CCK站共存。具有无争用周期（CFP）的信标信号从接入点发送到多个站。在CFP结束之前，OFDM调制数据被发送到多个站，在CFP周期结束之后，发送DSSS / CCK调制数据，从而防止站点之间的冲突。

摘要： Wireless radio devices that communicate in close proximity to each other typically suffer from interference. Such interference between the wireless radio devices can result in performance degradation in either/both the wireless radio devices. Functionality can be implemented to schedule communications of one wireless radio device around communications of the other wireless radio device based on a coexistence table comprising scheduling information of the other wireless radio device. Communications of the wireless radio devices can also be controlled based on communication priorities. Functionality can also be implemented to dynamically control a number of packets transmitted in an aggregate based on the scheduling information.

摘要： A method and system for operating a wireless access point is disclosed. In an embodiment, a wireless access point determines whether bursty interference is present within the operating range of the wireless access point and then adapts a transmission characteristic in response to the determination. In an embodiment, the wireless access point determines whether bursty interference is present by changing at least one transmission characteristic and monitoring the resulting error rates. The presence of bursty interference can be detected if a lowering of the transmission rate causes an increase in the error rate. The increase in the error rate is a result of the lower transmission rate and corresponding longer transmission time for each frame, which in turn increases the likelihood that a frame will overlap with bursty interference.
摘要翻译：公开了一种用于操作无线接入点的方法和系统。在一个实施例中，无线接入点确定在无线接入点的工作范围内是否存在突发干扰，然后响应于确定来适配传输特性。在一个实施例中，无线接入点通过改变至少一个传输特性并监视产生的错误率来确定是否存在突发干扰。如果传输速率的降低导致错误率的增加，则可以检测到突发干扰的存在。错误率的增加是每个帧的较低传输速率和相应更长的传输时间的结果，这又增加了帧将与突发干扰重叠的可能性。
