The key feature of this system is its ability to offer low-cost, high quality and flexible services not currently available in areas not economical to serve terrestrially. It utilizes existing public and/or private network facilities to extend mobile users' global connectivity. GLOBALSTAR subscribers will be able to communicate wherever and whenever they happen to be. Furthermore, such operation is deemed to be both profitable and low risk.","PeriodicalId":254396,"journal":{"name":"IEEE International Symposium on Personal, Indoor and Mobile Radio Communications.","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131595016","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 influence of reuse distance, i.e. cluster size, and traffic intensity on the performance parameters has been investigated. The mobile environment is considered as (fast) Rayleigh fading channel. The UHF groundwave propagation law is introduced by considering the local mean power to be inversely propotional to the fourth power of propagation distance.","PeriodicalId":254396,"journal":{"name":"IEEE International Symposium on Personal, Indoor and Mobile Radio Communications.","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116253933","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}

Temporal variations are caused by human movement or human induced motion of the communication equipment on the otherwise static indoor radio channel.

Using this model, the performance of a BPSK radio modem operating in rooms with different sizes and the systems with different power level, outage requirements and antenna systems is evaluated. It is shown that if the omnidirectional antenna is used in a 30m by 30m room, the data rate cannot reach above 5 Mbps with an outage rate of .01 for the acceptable error rate of .0001. If a six-sector antenna system is used, and the selection criterion is to choose the sector with the largest power, a data rate of 2OMbps can be achieved in the same environment. For a given data rate of 15 Mbps and a transmitter power of lw, the omnidirectional antenna system cannot reach an outage probability of .01 with in a 10m by 10m room.

Using these schemes upper bounds on the performance of power control schemes are derived. Numerical results indicate that these upper bounds exceed the performance of conventional systems by an order of magnitude in interference suppression and by a factor of 5 in capacity.
