摘要： The present invention provides an efficient point-to-multipoint microwave ATM network including a base station (BS) broadcasting a continuous transmission with a sector antenna. The system uses time division multiplex (TDM) for downstream transmission and time division multiple access (TDMA) for upstream transmission. The downstream transmission consists of ATM cells encapsulated in MAC protocol data units (PDUs) for forward error correction (FEC) and synchronization. Small Subscriber Terminals (STs), including Subscriber Radio Units (SRUs), receive the broadcast and pass it to a Subscriber Access System (SAS) that drops the ATM cells addressed only to them. To allow strong FEC protection and to maintain the same symbol rate as the downstream transmission without sacrificing bandwidth, a modified trellis code modulation technique, which incorporates Reed Solomon coding, is used during upstream transmission.

摘要： A method of supporting voice-band modem-to-modem calls in a wireless communication system is disclosed. In some embodiments, once a modem call is detected, the modem call is terminated. Data in the terminated modem call is then demodulated and relayed from one end of a wireless broadband channel to the other end of the wireless broadband channel. Transfer of the data to the second modem is completed when the other end of the wireless broadband channel places a modem call to the second modem. By sending data in high-rate modem calls via a wireless broadband channel rather than over multiple, dedicated wireless voice channels, resources of the wireless communication system are utilized more efficiently that can result in significant gains in system capacity.
摘要翻译： 公开了一种在无线通信系统中支持语音频带调制解调器到调制解调器呼叫的方法。 在一些实施例中，一旦检测到调制解调器呼叫，则调制解调器呼叫被终止。 接收终端的调制解调器呼叫中的数据然后被解调并从无线宽带信道的一端中继到无线宽带信道的另一端。 当无线宽带频道的另一端向第二调制解调器发出调制解调器呼叫时，完成数据到第二调制解调器的传送。 通过经由无线宽带信道而不是通过多个专用无线语音信道发送高速率调制解调器呼叫中的数据，更有效地利用无线通信系统的资源，这可以导致系统容量的显着增加。
