Improved performance compared to the external modulation scheme previously reported is achieved and comparison with the use of a standard electronic up-converter shows only a slight degradation. The direct modulation represents a major improvement in terms of set-up simplicity and improves the efficiency of the conversion process. It does not degrade the phase noise properties of the photonic oscillator. This simple set-up allows as well the distribution (over 50 m) of the 60 GHz radio signal using radio-over-fibre. Transmission of the up-converted signal over 5 m of air does not show any significant degradation.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114932139","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}

A successful connection of IEEE802.11a was established between a mobile unit and the remote base station (BS) which in turn was connected via an optical fibre to the wireless access point. A maximum data throughput of 20 Mbps and 18 Mbps was achieved at a 10 m separation distance between the mobile unit and the BS antenna in the uplink and downlink directions respectively. Results are also presented for the data throughput performance of the system with varying free space distance and the measured average throughput in both transmission directions.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"221 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115786346","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}

Direct intensity modulation and direct detection (IM-DD) were employed in the system. The AP employs spatial diversity. Throughput measurements of the distributed IEEE802.11g signal were carried out at different locations in an office and indicated that high throughputs could be maintained even when the fiber length difference between the two RAUs was 200 m. These results are compared with throughput measurements taken when only a single port of the AP is used to drive the RAUs, that is, without making use of the spatial diversity. The results show a significant improvement in performance with spatial diversity.","PeriodicalId":115448,"journal":{"name":"2008 International Topical Meeting on Microwave Photonics jointly held with the 2008 Asia-Pacific Microwave Photonics Conference","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123528556","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}

We defined the suppression ratio of the crosstalk as the ratio of the mm-wave power of the desired channel and undesired channels which are estimated from optical spectrum of the detected RoF signal.
