Wideband local access: wireless LAN and wireless ATM
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 reviews the channel access rules that apply in the new unlicensed PCS band. The purpose of this article is to outline the channel access procedures and put them in the context of an operating system. This discussion provides a rationale for the rules and background scenario to aid understanding of the new rules. It should be noted, however, that the discussion in this article is provided for information only and is the viewpoint of the author. For details of compliance and further i...

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 ...

A prototype microcellular wireless asynchronous transfer mode network (WATMnet) capable of providing integrated multimedia communication services to mobile terminals is described in this paper. 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...

The explosive growth of today's wireless communication market has brought an in­ creasing demand for high performance radio-frequency (RF) circuits in low-cost tech­ nologies. Because of advancements in RF CMOS circuits, devices, and passive elements in the last decade, it has become possible to develop a RF system-on-chip (SoC) that integrates RF, analog and digital circuits completely. Direct downconversion, or zeroIF downconversion architecture, shows an advantage over traditional superhetero...

Wireless video in acceptable quality is only possible by following an end-to-end approach. WaveVideo is an integrated, adaptive video coding architecture designed for heterogeneous wireless networks. It includes basic video compression algorithms based on wavelet transformations, an efficient channel coding, a filter architecture for receiver-based media scaling, and error-control methods to adapt video transmissions to the wireless environment. Using a joint source/channel coding approach, Wave...

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...

Analytical results for a frame- and car- rier frequency synchronization scheme with repetition preamble (2) are derived. When such a preamble is composed of random Orthogonal Frequency{Division Multiplexing (OFDM) symbols with cyclic preflx, a surprising statistical efiect occurs in non{dispersive channels; the lock{in probability of the frame synchro- nizer is non{uniformly distributed inside the valid syn- chronization range. This efiect is illuminated with a theory which perfectly corresponds...

The wireless data communication industry has experienced fast development in the past few years. With the finalization of new series of IEEE 802.11 and ETSI BRAN HIPERLAN standards, new features have been integrated into the conventional wireless LAN, which was introduced as an alternative of fixed LAN. New emerging technologies, such as HomeRF and Bluetooth, are becoming new impetus for the fast expansion of the market. In this paper, we present an overview of the current status and future tren...

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...

One step toward the realization of the CASCOM vision is the development of an intelligent agent-based peer-to-peer (IP2P) environment. IP2P environments are extensions to conventional P2P architectures with components for mobile and ad hoc computing, wireless communications, and a broad range of pervasive devices. Software agents will be a key technology to address the challenges of CASCOM as they offer an adequate abstraction for dealing with services from pervasive devices in IP2P environments...
