    Abstract: The convergence of computing and communications is upon us. What this concept implies for network operators is that the wireless industry can soon expect demand for wireless data services to increase, driven by mobile computer users. Operators have an opportunity to get their networks ready and potentially capitalize on this demand.

    Bluetooth technology is expected to be a key enabler of this convergence by solving a major ease of use obstacle for mobile end-users. Bluetooth technology allows for the replacement of proprietary cables that connect one digital device to another with a universal short-range radio link. Mobile computers, cellular handsets, network access points, printers, PDA’s, desktops, keyboards, joysticks and many other devices can be embedded with Bluetooth radios. Once ubiquitously deployed in mobile devices, Bluetooth technology has the potential to take wireless data usage to a new level. The first products enabled with Bluetooth technology are expected to appear on the market as soon as the first half of 2000.

    The implications for the wireless data services industry are large. The advent of Bluetooth technology is coming at the same time that a new generation of faster, lighter, lower cost and more powerful mobile computers and cellular handsets arrive. At the same time there is growing public acceptance of data applications such as e-commerce. Operators have an opportunity to capitalize on these developments if they are ready. The removal of the ease-of-use obstacle should help drive up demand for data services, but operators need to address other major obstacles – low data transmission speeds, lack of awareness and lack of marketing of data services.

    Network operators can view the deployment of Bluetooth technology as a potential call to action to focus on data. They can upgrade their network infrastructure to newly available higher speed data technologies, and expand their marketing of data services. Operators can prepare to build their customer base beyond voice, and be ready to reach and serve a broader market of mobile data customers.

    This paper complements the presentation by Intel Corporate Vice President Stephen Nachtsheim at the 1999 GSM World Congress, where he will describe the impact of Bluetooth technology on GSM terminals, mobile computing, cellular data services, applications, and the wireless market segment. Mr. Nachtsheim will also demonstrate the technology. This paper is available at the Mobile Data Initiative’s website: http://www.gsmdata.com/cannespaper.htm.

     

    Overview:

    This paper presents a description of the key environmental issues driving wireless data, the evolution of the mobile computers, Intel’s and industry efforts to make wireless data accessible and easy to use through Bluetooth technology, and a call to action for network operators.

     

    Introduction - Issues driving wireless data

    The cellular industry has been very successful in marketing voice services to businesses and consumers. This highly competitive industry seems to agree that the next big opportunity for wireless networks will be differentiation based on data and multimedia services. Several factors have converged to create this opportunity. On the computing side, advances in mobile technology and price reductions have turned mobile computers into practical and cost effective tools for mobile business users. On the communications side, the robust data capabilities of GSM technology have made it possible for a business user to plug a cellular phone into a mobile computer and gain access to the Internet and corporate networks.

    However, several obstacles have thus far prevented more widespread adoption of mobile data services by end users. Chief among the obstacles is that mobile data computing has been frustratingly complex to connect and configure. Other major obstacles have been the low data transmission rate and the unavailability of data services globally. Mobile devices themselves have been expensive and cumbersome for mobile users. The security of data transmitted wirelessly has always been a concern to users. Finally, potential customers often have not known of data services’ existence.

    This picture is about to change dramatically because solutions to these obstacles are here. These are expected to act as a catalyst to the growth in demand for mobile data, and to accelerate the convergence of computing and communications. The implications are large for network operators, with the creation of new opportunities to address the needs of an increasingly mobile world.

    Intel has been active in driving the mobile computer market segment to address customers’ needs. As part of our effort to increase the value of our mobile products and improve ease of use, we continue to help develop and promote new capabilities. One of these, known as Bluetooth technology, will have a tremendous impact on mobile computing and communication as we know it today.

    Bluetooth technology and standards will allow for the replacement of proprietary cables that connect one device to another with a universal short-range radio link. Bluetooth radio links built into both the cellular phone and the computer would replace the cumbersome cable used today to connect a mobile computer to a cellular phone. The first Bluetooth technology-enabled products are expected to appear as soon as the first half of 2000.

    Bluetooth technology is being developed through the combined contributions of the members of the Bluetooth Special Interest Group founded by Ericsson, IBM, Intel, Nokia and Toshiba. As of October 1998 about 200 members had signed up. The Bluetooth SIG is seeking to make it available worldwide in high volume production of devices including mobile computers, handsets, PDA’s, network access points and many other devices.

    The implications of untethering computing and communications devices are significant. Bluetooth technology will change the way mobile communications terminals and mobile computers interact, and more broadly, it may change the way we communicate and compute. It is expected to create new uses for computing and communicating devices, and create a myriad of opportunities for new applications and data services. Network operators can realize these potential opportunities by readying their infrastructures and offering innovative new services to users.

     

    The evolution of the mobile computers

    The data services market segment is primed to grow. Among the biggest factors leading up to this are major developments in mobile computers over the last two years.  These have mainly been in the arenas of  market segmentation, data connectivity, price and performance. As a result of these advances, demand for mobile computers has been overwhelming - the Intelā Pentiumā II for mobile computers ramped faster than any previous CPU, either mobile or desktop.

     

    Market segmentation: As with cellular phones and desktop computers, market segmentation is occurring among mobile computers. From the mobile end user perspective, this means that a range of form factors and prices are now available for very powerful mobile computers.

    In addition to the full-sized professional notebooks, there are now several new form factors to choose from: performance/mainstream, thin and light, and the mini notebook. The latter device weighs less than three pounds by incorporating a scaled-down keyboard and LCD screen, and by using external CD-ROM drives and other peripherals. Business users purchase mini-notebooks primarily as a second PC, to use for e-mail, Internet access and calendar applications when they are away from the office. Some of these devices are the size of a videocassette, an ideal platform for mobile data users.

     

    Data connectivity: Current mobile computers are easier to connect and use than before, thanks in part to new generations of software that incorporate mobile features and efforts such as the Intel-founded Mobile Data Initiative. Connectivity and ease of use will be taken to the next level once devices are embedded with Bluetooth radios.

     

    Price: Mobile computers have become much more affordable in the last two years. The average purchase price points have been dropping, and lower price points are emerging. The steady reduction in the costs of LCD displays and other components, as well as improvements in process technology in microprocessor manufacturing, have allowed prices to drop. An Intel® Pentium® II processor-based mobile computer that provides great performance for standard business applications can now be purchased for well under $2,000. In addition, Intel’s Wired for Management initiative has reduced the total cost of ownership by making notebooks easier to manage in a corporate environment.

     

    Performance: Mobile computers now rival desktop systems in performance. When you combine the latest Intel® Pentium® II processor with greatly improved LCD displays, graphics capabilities, several gigabyte hard drives, improved batteries and many other features, you have a high end system that allows mobile users to work and access information, wherever and whenever they want to.

    Advances in process technology have had a huge impact on mobile performance. Probably the most relevant advance is the continued voltage scaling that silicon technology has offered over the last few years. This enables increased performance with lower power consumption.

    Security has always been a major concern for users considering wireless data computing, and the industry has striven to address this issue. The latest generation of mobile devices includes enhanced security and authentication features, and more are planned. The rapid increase in e-commerce activity in the past year is perhaps testament to some alleviation of security concerns.

     

    Bluetooth technology

    On the connectivity and ease of use side, the computing and communications industries have been struggling with the question of how to eliminate the last cumbersome cable – the data connection cable between the cellular phone and the mobile computer. There were several conditions for a successful solution. The solution had to be global, inexpensive, use little power, and provide high bandwidth to accommodate the data and multimedia content required and demanded by notebook users.

    Since no solution yet existed and nothing was on the drawing boards of the cellular industry to address these requirements, a new paradigm was required. A proposal was made to bridge the notebook and cellular phones by integrating into each a short range radio in the free 2.4GHz spectrum. This concept is the basis for the Bluetooth technology industry initiative.

    Bluetooth technology was designed for and will be optimized for use in mobile devices. Mobile computers, cellular handsets, network access points, printers, PDA’s, desktops, keyboards, joysticks and virtually any other device can have Bluetooth radios integrated into them. First generation Bluetooth radios will use tiny radio-frequency transmitters, no larger than 1.0 by 0.5 inches, that can run off a watch battery for months.  Power considerations are always important for battery-powered mobile devices, and Bluetooth’s low power modes are planned to meet those requirements with less than 0.1 W active power. And since Bluetooth is designed for both computing and communications applications, it is designed to support high quality simultaneous voice and data, with robust data transfer rates of up to 721 Kbps.

    Bluetooth technology is being developed through the combined contributions of the members of the Bluetooth Special Interest Group.  Intel brings architectural knowledge, advanced silicon technology, manufacturing expertise and software components to the group. Ericsson contributed the basic radio technology. Nokia is contributing the radio technology and mobile handset software. IBM and Toshiba are developing a common specification for integrating Bluetooth technology into mobile devices. In addition to the founding members of the special interest group, about 400 additional companies have signed up as adopters to support the technology and to ensure that Bluetooth radios will be implemented in many different devices. Bluetooth SIG members are very pleased with the unprecedented level of cross industry commitment to this initiative.

    Bluetooth technology is being developed as an open specification, and will be licensed royalty free to all companies who sign up to become members of the Bluetooth initiative. This open specification will allow a quick proliferation of the technology through a wide range of mobile products and devices. The first products with Bluetooth radios integrated in them to be available as soon as the first half of 2000.

    Among the most promising aspects of Bluetooth technology are the ease of use it offers mobile computer users and the new uses it makes conceivable.

    Ease of use and new uses

    Freeing users from the challenges of finding connectors and cables to link their computing devices is just one of the ways Bluetooth radios will make mobile computing easier.

    Bluetooth architecture will allow "hidden computing" usage models. What does this mean? It refers to the ability to use one device to perform a function while the other connected device necessary to aid in the function is "hidden" - stored in a briefcase or pocket, or out of sight, for instance. For example, users will be able to write an e-mail message on their mobile computer and be able to send it wirelessly without removing their handset from their pocket. Another example could be that a user would translate e-mail messages into speech and listen to them over a handset while in a taxi, with the handset connected via a Bluetooth radio to a mobile computer in the trunk.

    Another example of hidden computing might be the ability for devices to synchronize with each other when they are within range. One important capability of Bluetooth architecture will be to allow automatic synchronization of information such as an e-mail application, calendar or address book, for example, when they are within range of each other.

    Many others uses can be imagined. As the technology development continues, we expect to see new ideas that we have not even imagined to this point.

    With a mobile computer and mobile phone each integrated with a Bluetooth radio, users will be able to wirelessly access the Internet or corporate intranet from a mobile computer at speeds similar to PSTN, ISDN, or xDSL connections, once the right network infrastructure has been put in place by operators. There will be no more need for special cable connectors to a mobile phone, LAN line, or phone line. The only requirement is for the mobile computer to be within range of an access point such as a handset.

      

    A call to action to network operators

    The developments described above in mobile computing technologies and ease of use are expected to make wireless data ubiquitous. This may translate into continuous growth for the mobile computing and communications market segments. But this growth can only be realized if there is a data "dialtone", and if customers know that it’s there and that it will meet their data needs.

    In order for network operators to potentially capitalize on these developments, they could make themselves ready. Bluetooth architecture addresses the ease-of-use aspect, but cannot remove the major network obstacles – low data transmission speeds, lack of awareness and lack of availability of data services globally.

    Network operators should view Bluetooth technology deployment as a potential call to action to upgrade their network infrastructure to newly available higher speed data technologies such as HSCSD, GPRS and EDGE, which are in trials now, and already being deployed by some networks in mid-1999. These will boost speeds to over 100 Kbps, which is expected to be a major incentive for customers compared to the currently available speed of 9.6 Kbps.

    Network operators should also start building their customer base of data users now and begin to think differently about how they emphasize their services. Many customers today have no idea that they can connect their handset to their mobile computer and have access to data services. As industry analyst Andrew Seybold recently said regarding data, "it could be a significant windfall for network providers who are interested in obtaining and keeping new customers." (Seybold’s Outlook, August 1998.) Operators can prepare to build their customer base beyond voice customers, and be ready to reach and serve a broader market of mobile data customers.
