Abstract
An overview of the status of wideband wireless local access technologies is provided. Service scenarios and availability of the market and products for wireless LAN and wireless ATM technologies are discussed. Similarities among IEEE 802.11 and HIPERLAN standards for wireless LANs and the developing prototypes for wireless ATM are evaluated. An update on the status of the available unlicensed bands in the United States as well as the status of the wideband wireless projects in the European Community and Japan are presented.

HIPERLAN is the new European standard for radio LANs currently being formulated by ETSI RES10 for operation at 5 GHz and 17 GHz. It will be suitable for radio replacement of wired LANs and for ad hoc networking providing a user data rate of 10–20 Mbit/s. This paper is a review of the work of ETSI RES10 on the formulation of the HIPERLAN standard. The origins of ETSI RES10 are documented. The targets set for HIPERLAN and the problems in achieving these targets are discussed. The paper reviews the...

Recent developments attest to wide interest in wireless asynchronous transfer mode (ATM). The Federal Communications Commission (FCC), for example, recently announced that it will open up 350 MHz of bandwidth in the 5-GHz band for inexpensive Internet access at schools and libraries. Moreover, in June 1996, the Wireless ATM Working Group was formed within the ATM Forum. Bell Labs has been working on a wireless ATM prototype in its Mobile information infrastructure (MII) project, which is partial...

Pahlavan (1985) published an article entitled "Wireless office information networks". That article examined spread spectrum, standard radio and infrared (IR) technologies for intra-office wireless networking. In May of that year the FCC released the ISM (industrial, scientific, and medical) bands for spread spectrum local communications. Although ISM bands are not restricted to any specific application, wireless local area networks (LANs) were one of the most prominent applications that were env...

This article examines the telecommunications and socioeconomic trends in the USA that are forcing regulators and policy makers to re-examine the concept of universal service. It proposes criteria and guidelines for redefining universal service in this changing environment, and performance indicators that may be used to monitor compliance. The relevance of this approach for other countries is discussed, with examples of how these principles and guidelines could be adapted for specific country req...

As technology evolves, it is now feasible to implement sophisticated adaptive routing scheme on networks which support different kind of services with heterogeneous bandwidth characteristics. Adaptive routing can increase the network throughput by routing calls to less congested paths. It can also be used to bypass transmission facility failures. In this paper, we analyze and compare two adaptive routing schemes. The first is called the maximum mean time to blocking (MTB) routing which is based ...

The experimental system's hardware consists of laptop computers (NEC Versa-M) with WATMnet interface cards, multiple VME/i960 processor-based WATMnet base stations, and a mobility-enhanced local-area ATM switch. The prototype wireless network interface cards operate at peak bit-rates up to 8 Mb/s, using l...

The SWAN (Seamless Wireless ATM Network) is an experimental indoor wireless network that instigates the combination of wireless access with multimedia networked computing in an indoor setting. It is based on room-sized pico-cells and mobile multimedia endpoints. It enables users carrying multimedia endpoints, such as personal digital assistants (PDAs), laptops, and portable multimedia terminals, to seamlessly roam while accessing multimedia data resident in a backbone wired network. The network ...

The paper presents a simulation study of TCP performance over congested ATM local area networks. The authors simulated a variety of schemes for congestion control for ATM LANs, including a simple cell-drop, a credit-based row control scheme that back-pressures individual VCs, and two selective cell-drop schemes. The simulation results for congested ATM LANs show the following: (1) TCP performance is poor under simple cell-drop, (2) the selective cell-drop schemes increase effective link utilizat...

Quality of Service (QoS) support has generally been lacking from WPAN and WLAN technologies, which has motivated the research of TUTWLAN. Design objectives have been relatively simple network architecture and capability to support real time services ranging from sensor data to multimedia streaming. The main TUTWLAN entities for QoS support are the Medium Access Control (MAC) protocol called TUTMAC and TUTWLAN Access Point (AP). The channel access is based on dynamic reservation Time Division Mul...

This paper proposes a new optical polarity-reversing correlator for optical CDMA radio highway network. We theoretically analyze the carrier-to-interference-plus-noise power ratio of regenerated radio signal at the control station. Analysis results clarify that optical CDMA using bipolar code sequences can be applied to the fiber-optic link of radio highway and we can assign more distinct code sequences to radio base stations compared with the unipolar type correlator using prime codes. By the p...

Next generation networks no doubt will include various types of multimedia data, ranging from real-time news updates to audiovisual multicast events. Multimedia terminals play an integral role in the overall information access fabric. While traditional desktop and settop terminals most likely will continue with the existing technology, portable and wireless multimedia terminals have lots of research and development issues to be solved. This paper starts with reviewing current technology through ...

This paper presents a 12.4 mW front-end for a 5 GHz wireless-LAN receiver fabricated in a 0.24 /spl mu/m CMOS technology. It consists of an LNA, mixers and an automatically tuned third-order filter controlled by a low-power PLL. The filter attenuates the image-signal by an additional 12 dB beyond what can be achieved by an image-reject architecture. The filter also reduces the noise contribution of the cascode devices in the LNA core. The LNA/filter combination has a noise figure of 4.8 dB and t...

Efficient radio resource utilization and fairness are important goals that must be achieved since wireless ATM systems support various services with different traffic characteristics such as CBR and UBR. This paper proposes a novel delay-and-queuing data size-based MAC protocol for broadband wireless ATM. The proposed MAC protocol relies on a new resource scheduling algorithm that decides the priority of channel assignment based on both the queuing delay and the queuing data size in the transmis...

We describe the roaming service with mobile IP between public WLAN and cdma2000 1/spl times/ Ev-Do design, and implemented. In terms of network configuration, the coverage of public WLAN network is overlapped with that of Ev-Do network. In this configuration, mobile terminal will decide the access system among the available systems. We propose the roaming method based on measuring the power of WLAN signal in hybrid network environments, and implement it. In order to confirm the effectiveness of ...

This paper proposes a unified matrix-analytic approach to characterize the output processes of general discrete-time lossless/lossy queueing systems in which time is synchronized/slotted into fixed length intervals called slots. The arrival process can be continuous- or discrete-time Markovian processes. It can be either renewal or non-renewal. The service of a customer commences at the beginning of a slot, consumes a random number of slots, and completes at the end of a later slot. The service ...

In a hybrid TDMA/FDMA digital communication system such as the GSM system, Global System for Mobile communications, a channel is defined by a tuple consisting of frequency band number and slot number. For a normal voice connection, an idle time slot will be assigned upon a channel request in uplink direction and correspondingly one for downlink direction. For multimedia applications with multi-rate connections, multiple slots are to be assigned. The problem of how to assign the slots efficiently...
