    Springer
    Wireless personal communications 3 (1996), S. 389-396 
    Details
    ISSN: 1572-834X
    Keywords: Patch antenna ; wireless LANs ; HIPERLAN
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract A patch antenna suited for indoor HIPERLAN is presented. The antenna operates in T M 02 mode and its radiation pattern is omnidirectional in azimuth and has a null in the normal direction. An experimental prototype has been designed and tested. A 6.1% bandwidth of VSWR≤2 and 4.2 dB antenna gain were measured at 5 GHz band.

    A discussion of some of the issues facing the regulator in dealing with the newly developing nomadic services including HIPERLAN (1996)

    Notes: Abstract HIPERLAN is a new standard for nomadic computer equipment being developed by ETSI. The practicalities of licensing of such computer networks make it unlikely that there will be an individual licensing scheme. Nomadic equipment cannot be restricted to certain regions or countries. There are clear indications that it will play an increasingly large role in communications. The best solution to the issue of nomadic equipment and its future development would appear to be an international effort at spectrum planning and frequency allocation.

    Predicted HIPERLAN coverage and Outage performance at 5.2 and 17 GHz using indoor 3-D ray-tracing techniques (1996)
    Springer

    ISSN: 1572-834X
    Keywords: HIPERLAN ; ray tracing ; equalisation ; propagation

    Notes: Abstract The European Telecommunications Standards Institute (ETSI) has recently defined a European standard for High Performance Radio LANs. This standard, known as HIPERLAN, has dedicated spectrum in both the 5 GHz and 17 GHz frequency bands. The system has been designed as an indoor wired-line replacement offering raw data rates in excess of 20 Mb/s. In this paper, simulated propagation data at 5.2 GHz and 17 GHz has been generated for a typical HIPERLAN environment. The analysis was performed using an indoor three dimensional ‘ray-tracing’ algorithm developed for site specific single floor environments. The model is capable of predicting narrowband (power) and wideband (time dispersion) characteristics even in non-line-of-sight locations. Using this propagation information, the design of a suitable equaliser and the expected coverage of a HIPERLAN node is investigated for a particular indoor location. Emphasis has been placed on the need to develop low cost and robust receiver designs that are compatible with the design goal of a small and low power terminal.

    Comparative indoor RF channel soundings at 2, 5 & 17 GHz (1996)
    Springer
    Wireless personal communications 3 (1996), S. 353-363 
    Details
    ISSN: 1572-834X
    Keywords: HIPERLAN ; LAN ; delay spread ; channel sounding ; indoor radio propagation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract There is a relatively large selection of results for indoor channel soundings at frequencies around 1 to 2 GHz but relatively few at the HIPERLAN frequencies of 5 and 17 GHz. This work provides some results taken at all three frequencies in order to redress this deficiency and also to compare results at these frequencies. A 20 GHz network analyser was used to perform the soundings. The analyser was capable of performing the Chirp Z transform to convert complex frequency response data to the time domain. Soundings were made in the Agency's office headquarters at Waterloo London and in their investigation facility at Whyteleafe. These two locations provided some diversity of sounding environments involving small offices, meeting rooms and large laboratories. Both buildings were of a 1930's style brick construction with some modern plaster board internal walls. Decay exponents and delay spreads are given for the test frequencies. Results show similar delay spreads at all frequencies.

    Co-channel and self-interference analysis for indoor wireless channels (1996)
    Springer
    Wireless personal communications 3 (1996), S. 411-419 
    Details
    ISSN: 1572-834X
    Keywords: Co-channel interference ; self-interference outage ; HIPERLAN ; indoor wireless systems

    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract To achieve a user data rate of 20 Mbit/s in the high performance local area network (HIPERLAN) system operating in indoor environments, channel equalization must be used to mitigate the effects of multipath propagation. If, however, the indoor channel impulse response length is too long, then the multipath power outside of the equalisation capability of the equalizer acts as a form of self interference. Moreover, co-channel interference may also be present at the detector input. Considering these two effects as well as the rms delay spread, this paper derives analytical expressions for the probability of outage.

    Signal processing hardware in a radio LAN demonstrator (1996)
    Springer
    Wireless personal communications 3 (1996), S. 429-443 
    Details
    ISSN: 1572-834X
    Keywords: HIPERLAN ; radio LANs ; equalisation ; DFE
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract In order to demonstrate the practicality of high speed radio LANs, such as HIPERLAN, a hardware demonstrator has been built. To overcome the inter-symbol interference caused by the dispersive nature of the indoor radio channel, a decision feedback equaliser has been included in the system. No central synchronisation is provided in a network and a node must be able to derive all synchronisation from a received packet. This paper describes all of the signal processing hardware built for the demonstrator. The demonstrator is not standards compliant but the physical layer parameters are very similar and the signal processing required in HIPERLAN equipment will be very similar to that in the demonstrator.
