Broadband Wireless Access (WiMAX & WiFi)
B. K. Banerjee - Senior Business Manager (Global Telecom Solutions Sector), Motorola India

The requirement for Band width is insatiable, like the desire for money. Users want faster downloads, instant access and interactive gaming all needing larger and larger bandwidths. While fibre is probably the best medium with unlimited bandwidth, making it available to everywhere still pose economic challenges. For long scientists/technologists and Vendors are trying out different wireless technologies to take the bandwidth to where needed. While there has been plethora of technologies and vendors providing high BW wireless access, WiFi and now WiMAX are the probably the two that has the most potential and attracted the max investment/attention.

This paper will examine in brief the commercial and technological implications of Broadband Wireless Access.

Emerging Opportunities in RFIDs and Wireless Broadband Technologies
Dr. Rajeev Shorey - Research Staff Member, IBM India Research Lab

Synopsis:
Wireless networks have seen an exponential growth in the last decade. Even as wireless cellular networks continue to grow, as is seen by current activities in 3G standard, the interest in these networks has saturated and has given way to sensor networks, wireless LANs, wireless MANs and mesh networks.

On the one end of the wireless spectrum is the simple RFID technology. Even though RFID is relatively new to the mass market, it has now become a household word. RFID is an electronic tagging technology that allows an object, place, or person to be automatically identified at a distance without a direct line-of-sight, using an electromagnetic challenge/response exchange. Typical applications include labelling products for rapid checkout at a point-of-sale terminal, inventory tracking, timing marathon runners, secure automobile keys, and access control for secure facilities.

Two emerging technologies that have caught the attention of the world is wireless ad hoc networks and sensor networks. Ad-hoc wireless and sensor networks are emerging as technologies of great practical importance, with their applicability spanning surveillance, emergency response, healthcare, and other commercial applications. Novel approaches are needed to address the challenges of ad-hoc networks, which lack a fixed infrastructure. The topology of ad-hoc wireless networks is dynamic, decentralized, and the nodes forming the network usually have transient connectivity. Hence, networking techniques for these environments must be power-aware, adaptive, and lightweight. Wireless sensor networks are a class of ad-hoc wireless networks that consist of power-constrained, multi-functional sensor nodes which have a small form factor. These tiny sensor nodes consist of sensing, data processing, and communicating components, and are capable of collaborating with each other in an uncertain environment. Wireless sensor networks are evolving from simple data transportation networks to functionally rich distributed systems that additionally support actuation.

A specific form of ad hoc network called "mesh" networks is gaining tremendous popularity. In a wireless mesh network, multiple nodes cooperate to relay a message to its destination. The mesh topology enhances the overall reliability of the network, which is particularly important when operating in harsh environments. This technology delivers self-configuring, scalable, and self-healing networks. Mesh networks dynamically route packets from node to node. Only one access point needs to be connected to the wired network, with the rest sharing a connection over the air. The resulting network is less expensive than a traditional WLAN (wireless LAN).

The talk concludes with a description of a cable replacement technology called WiMax. WiMax is a wireless technology that can provide up to 70M bit/sec of throughput over several miles in the unlicensed or licensed bands. The industry is looking towards the end of 2005 for the general availability of Wi-Max radios based on the first generation of WiMax silicon. WiMax has caught attention in the last one year since it is a possible rival to wired broadband services.

Manufacturers and service providers believe that WiMax is round the corner and has the potential to be widely deployed, and be popular in the near future the same way Wi-Fi has been popular in last few years.

Extending Wireless Awareness into Corporate Network Infrastructure
Parag Arora - Business Development Manager, Cisco Systems, India & SAARC

Synopsis:
There is an emergence of Wireless technology framework to integrate and extend wired and wireless networks to deliver the lowest possible total cost of ownership for companies deploying wireless LANs (WLANs). The flexibility of this framework allows network managers to design the network to meet their specific needs. There are four components to the framework: access points; management and security servers; WLAN clients; and infrastructure devices. Core components and optional components can be deployed based on the size and requirements of the network. Cost effective solutions based on this integrated framework ensure that wireless LANs have the same level of security, scalability, reliability, ease of deployment, and management as wired LANs.

RFID - The next wave
Ratheesh Raveendran - Solution Architect, SAP India

Synopsis:
Radio frequency identification (RFID) is a powerful new technology that is helping companies to improve visibility into their inventory data and increase accuracy across supply chain networks. The presentation will give a bird's eye-view of how RFID works and its relevance for Supply Chain applications. The progress SAP has made in this space would also be discussed

Mesh Architecture - The Answer to Enterprise Wide Wireless LAN Deployment
Raghunandan Charan - Business Consultant, American Megatrends

Synopsis:
First Generation wireless Access Points deployed in public hotspots enabled islands of wifi zones for wireless internet access. The same Access Points have found their way into boardrooms and conference areas in Enterprises. As a Second Generation solution, multiples of these Access Points managed by a Wifi switch or AP controller is one of the answers for enterprise wide WLAN deployment. The Third Generation Mesh Architecture with distributed intelligence offers Enterprise wide pervasive wireless network providing all of the management and security that network managers have come to expect - Making Wireless like Wired.

Multimedia over Wireless: Overcoming Challenges
Vivek Wandile - Chief Architect, Wipro

Synopsis:
WiFi has become pervasive in office and public environment today. Networked devices are rapidly going wireless, more so in the digital home segment. Consumers now demand products that are capable of wirelessly streaming multimedia content from multiple sources, like watching a movie from Cable/Internet/PC/PVR/DVR or watching video feed from Camcorder or listening music from DVD Audio.

Multimedia streaming over Wireless provide a unique set of challenges, like unreliable transmission medium, limited bandwidth availability and variable behaviour of the medium. These result in poor quality multimedia rendering at the receiver.

This presentation will detail how the above problems are analysed and addressed. The residential environment is modelled in a network simulation model and the optimum solution to address the various issues is described.
