The question of interest is whether or not wireless connections can be used for accessing distant sensors and actuators through fieldbus [Pleinevaux and Decotignie 1993]. The question of interest is where the bandwidth of available wireless connections allows access to distant sensors/actuators through a fieldbus protocol. The paper describes a gateway design for the extension of a FIP standard fieldbus through a narrowband radio channel. The performance limit is evaluated and an example given for a 9600 bps channel.","PeriodicalId":433500,"journal":{"name":"Proceedings of 6th International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124127104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When we transmit multimedia information such as speech, image and data, differences in the information rate, traffic performance and required quality should be taken into account. The wireless CDMA system can achieve a flexible balance of these differences if the transmission power distribution is controlled using channel measurement information such as traffic. The optimal control of transmission power is derived by linear programming and nonlinear programming. Numerical results demonstrate that the proposed method can satisfy the required quality.","PeriodicalId":433500,"journal":{"name":"Proceedings of 6th International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126841713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Support of user terminal mobility, particularly the capability for fast and seamless handoffs, over the B-ISDN is an expected requirement that is not currently met. We propose extensions to the B-ISDN user transport and signaling network architectures and signaling protocols to meet these requirements. The proposed extensions optimizes the handoff delay over the B-ISDN while minimizing the resources allocation, chances of handoff failure, and the call processing load in the intelligent network (IN). The network architecture extensions are backward compatible to current B-ISDN standards and implementations.","PeriodicalId":433500,"journal":{"name":"Proceedings of 6th International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127428269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Voice and data transmission over an 802.11 wireless network 通过802.11无线网络传输语音和数据

The data is transmitted in a contention based access period, while the voice samples are transmitted during a contention free period, based on a polling scheme. Because statistical multiplexing can be utilized, speech may be outdated when a poll arrives. The portion of outdated speech is then clipped to decrease the load on the channel. We analyze the quality of the voice conversations in terms of the percentage of bits clipped as well as the throughput of the data for various parameters. We show the boundary conditions involved in the transmission of voice over the WLAN and demonstrate the impact of a time-bounded service on the throughput during the contention period. The results show that the high overhead introduced by the 802.11 WLAN standard results in a low number of possible voice conversations. It can also be concluded that the cooperation of the contention based and contention free periods results in a poor performance. Further, variation of the maximum payload size reveals that the largest possible maximum payload size must be selected to minimize the percentage of clipped bits and maximize the throughput. Finally, we show that a larger superframe length provides the opportunity for more voice conversations or a higher data throughput, but requires increasing the time to live for the speech bits to retain an acceptable quality.","PeriodicalId":433500,"journal":{"name":"Proceedings of 6th International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"579 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129036605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The minimum number of channels required at a base-station to ensure a specified quality of service at a given capacity requirement is determined.

Abstract The technical feasibilit GaAs Monolithic circuits for wireless communicatmi application has been long proven in theory and practice [l-41. Still, the commercial success of the GaAs monolithic parts is not always guaranteed. In a paper published recently [5], an explanation was offered which attributes the reluctance of the large manufacturers to replace existing designs with monolithic designs. The muse according to the author is that competing designs based on dwrete components are as inexpensive and available as monolithlc solutions. This in fact is probably the single most important obstacle to a widespread commercial success of GaAs m o n o l i ~ c receivers for consumer wireless applications so far.","PeriodicalId":433500,"journal":{"name":"Proceedings of 6th International Symposium on Personal, Indoor and Mobile Radio Communications","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133670452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
