摘要： PROBLEM TO BE SOLVED: To provide a radio transceiver circuit capable of significantly reducing the overall size thereof.
SOLUTION: The present invention relates to a radio receiving circuit suitable for being integrated on a single IC chip together with a radio transmitting circuit, comprising: a down-conversion section arranged to down-convert a received first high frequency signal to an intermediate frequency signal; a band filter 220 connected to the down-conversion section and arranged to channel-filter a low intermediate frequency signal; and a detector 224 for information recovery, wherein the low intermediate frequency signal is around a sufficiently low frequency capable of integrating the band filter on the IC chip, and the down-conversion section, the band filter and the detector are integrated into a single IC chip.

摘要： PROBLEM TO BE SOLVED: To provide a cost-effective wireless network that can support both voice and data and for efficient use of the limited radio spectrum. SOLUTION: A wireless network includes master and slave units. The master sends a master address and clock to the slaves. Communication is performed by means of a virtual frequency hopping channel whose hopping sequence is determined according to a function of the master address, and whose phase is to a function of the master clock. Transmitted inquiry messages solicit slave address and topology information from the slaves, which may be used to generate a configuration tree for determining a route for a connection between the master and slave units. Slave address and topological information include own address from each of the slave units and only first order address lists from each of the slave units. Generating of the configuration tree includes generation of the hierarchy of connectivity rings from the first order address lists. COPYRIGHT: (C)2008,JPO&INPIT

解决方案：无线网络包括主设备和从设备。主机向主机发送主地址和时钟。通过虚拟跳频信道执行通信，其跳频序列根据主地址的功能确定，并且其相位是主时钟的功能。发送的查询消息从从站请求从站地址和拓扑信息，这些信息可用于生成用于确定主站和从站单元之间的连接的路由的配置树。从站地址和拓扑信息包括来自每个从单元的自己的地址，并且仅包括来自每个从单元的一级地址列表。生成配置树包括从第一个订单地址列表生成连接环的层次结构。版权所有（C）2008，JPO＆INPIT
