Billing Issues Wi-Fi vendors are also looking for ways to solve the problem of back-end integration and billing that has dogged the roll-out of commercial Wi-Fi hotspots. One model that can be used as the starting point is the way cell phone carriers have set up their back-end billing systems. However, the amount of capital required to set up a Wi-Fi hotspot is far less than that required for cellular operators (about $100 for a wireless base station vs about $1 million for a cell phone tower); hence, the economic scale will be quite different.

INTRODUCTION
Figure 1.11 What can WiMAX deliver
Some of the ideas under consideration for Wi-Fi billing include per day, per hour and unlimited monthly connection fees. Right now, users are willing to pay a premium for hotspot access, but as pricing becomes more competitive, hotspot owners will need a larger share of the revenues they generate for the equipment companies and hotspot providers.
Right now the most prevalent revenue share models value the network far more than the location. The owner of a venue hosting a hotspot receives substantially lower percentage of the revenue generated by the Wi-Fi hotspot, while the major part goes to the equipment manufacturer and the hotspot provider, which is responsible for support and installation.
Larger venues such as airports or convention centres can make a handsome amount even with a small share of the revenue, but venues like coffee shops, pubs, malls and fast-food outlets are not making attractive amounts from Wi-Fi hotspots. These venues being the key to driving Wi-Fi growth as well as penetration, hotspot providers and aggregators will need to offer them a larges slice of the pie to encourage more venues to install hotspots (Figure 1.11).

The prospect of broadband Internet access anywhere, at any time, has seemed a distant dream, far from reality for the vast majority of PC, laptop and handheld users. However, with WiMAX, it will soon become

something users cannot live without. WiMAX is one of the hottest wireless technologies around today.
WiMAX systems are expected to deliver broadband access services to residential and enterprise customers in an economical way. Although it has one name, WiMAX will be two different market technologies. The first is for fixed wireless and falls under the IEEE 802.16-2004 standard approved last year. The second, for mobile applications, will be under the 802.16e specification expected to be finalized this year.
As of now, fixed WiMAX is capable of becoming a replacement for DSL or cable or for network backhaul. In future, WiMAX will transform the world of mobile broadband by enabling the cost-effective deployment of metropolitan area networks based on the IEEE 802.16e standard to support notebook PC and mobile users on move.
There are many advantages of systems based on 802.16, e.g. the ability to provide service even in areas that are difficult for wired infrastructure to reach and the ability to overcome the physical limitations of traditional wired infrastructure. The standard will offer wireless connectivity of up to 30 miles. The major capabilities of the standard are its widespread reach, which can be used to set up a metropolitan area network, and its data capacity of 75 Mbps.
This high-speed wireless broadband technology promises to open new, economically viable market opportunities for operators, wireless Internet service providers and equipment manufacturers. The flexibility of wireless technology, combined with high throughput, scalability and long-range features of the IEEE 802.16 standard helps to fill the broadband coverage gaps and reach millions of new residential and business customers worldwide (Figure 1.12).

INTRODUCTION
What is WiMAX?
WiMAX is:
A wireless technology optimized for the delivery of IP centric services over a wide area.
A certification that denotes interoperability of equipment built to the IEEE 802.16 or compatible standard. The IEEE 802.16 Working Group develops standards that address two types of usage models: a fixed usage model (IEEE 802.16-2004) and a portable usage model (802.16 REV E, scheduled for ratification in 2005).
A scaleable wireless platform for constructing alternative and complementary broadband networks.
Commonly referred to as WiMAX or less commonly as Wireless-MANTM or the Air Interface Standard, IEEE 802.16 is a specification for fixed broadband wireless metropolitan access networks (MANs) that use a point-to-multipoint architecture. Published on 8 April 2002, the standard defines the use of bandwidth between the licensed 10 and 66 GHz and between the 2 and 11 GHz (licensed and unlicensed) frequency ranges, and defines a MAC layer that supports multiple physical layer specifications customized for the frequency band of use and their associated regulations. 802.16 supports very high bit rates in both uploading to and downloading from a base station up to a distance of 30 miles, in order to handle such services as VoIP, IP connectivity and TDM voice and data.
