TDK Systems believes that technology should work for people, that mobile technology should bring convenience, efficiency and enjoyment to people both in their business and personal lives. Some of the biggest users of mobile connectivity chose TDK Systems. Why? The answer’s simple. They know that the company’s technology can help shape their future.
Bluetooth wireless technology today
Today Bluetooth has become the de-facto standard for connecting data capable handsets to other devices such as handheld, laptop and desktop computers. Bluetooth is the glue that allows mobile applications to become compelling and ubiquitous for the mobile worker.
Bluetooth simplifies remote and mobile applications allowing the user to make use of “dead time”: to connect where and when he or she needs to. Users may have 100Mbits/s LAN Access in the office, 10Mbits/s within range of a Wi-Fi access point – but the GPRS Bluetooth-enabled handset means users can connect easily virtually everywhere in Western Europe and in may other parts of the world at speeds of 30 to 40K bits/s.
Bluetooth is being integrated in products such as handsets, printers, notebooks and handheld devices such as PDAs, more and more adapters are available to equip existing devices. Bluetooth allows devices to exchange, synchronise and transmit data; allowing peripherals to be shared, allowing devices to interact and unite in the personal area surrounding the mobile user. Bluetooth is in volume production – TDK Systems now ships more wireless products than wired products, the company has shipped over 200,000 Bluetooth adapters.
Economy of scale, cost reduction and availability of Bluetooth silicon is driving costs down strongly, Bluetooth may already be the lowest cost wireless technology of the future. As a reflection of its ubiquity, Bluetooth chipset volumes are fifty times greater than other volume wireless chipsets in current production.
Bluetooth adoption and the marketplace
The connectivity capability of today’s handsets, combined with their developing multimedia content capabilities, means that users increasing need to connect handsets to greater computing such as a PDA or computer to gain the benefit of their capabilities. For example, a data bandwidth of 30 to 40 kBits/s terminated on the mobile handset is not particularly useful – even for browsing WAP pages. Contrastingly, the same bandwidth is very useful when combined with a mobile computer – allowing email, Intranet access and remote applications to function substantially as they do in the cable connected realm of the office.
Eventually, TDK Systems envisages that users will but Bluetooth handsets and connectivity devices at the same time; particularly as the trend for personalising and accessing the multimedia capabilities of handsets becomes more and more popular with consumers. TDK Systems has created a new type of PC adaptor in this mobile entertainment sector that functions as a fully specified Bluetooth adaptor but also allows consumers to have fun with their phone by customising its wallpaper and screen image. Early in 2004 the company will launch a content portal that will allow users to access a unique range of multimedia content that user acquire via subscription. Content will be sent direct to consumers’ computer’s avoiding the need for content to be paid for using the premium Over The Air distribution model.
The strong demand for picture phones has also triggered demand for Bluetooth adaptors for computers. Many camera phones have Bluetooth capability; by utilising this users can transport their pictures from the phone to their PC in a few seconds. Once the image is available on the PC the possibilities for enjoying, using and sharing content are amplified, costs are also reduced – sending a photo as an MMS message has a distinct premium compared to sending a picture as an email attachment for virtually no cost.
Developing opportunities for Bluetooth
Responding to these developments, TDK Systems is adopting a vertical sector focus to tap the potential. An important area of opportunity developing is the industrial sector. In 2003, TDK Systems introduced a Bluetooth module capable of connecting existing devices and sub-systems; such as factory automation, which requires no intelligence in such systems. In this sector it is common to find that cabling represents a significant capital outlay as well as a sizeable maintenance cost. Bluetooth is an excellent cable replacement technology, it has the ability to replace many different cables carrying different types of signals such as analogue, digital and electrical control and telemetry signalling.
Often, a major obstacle for new technologies is the knowledge and familiarity barrier. New technologies need time to become accepted, understood and applied successfully at the engineering level, TDK Systems blu2i technology targets this barrier and reduces it dramatically. blu2i technology in the series of modules for embedded electronics, industrial and other integrated application features an embedded Bluetooth protocol stack allowing the modules appear as a conventional RS232 serial interface. In this way, legacy and even non processor-based equipment can be converted to cable-free operation. The modules also feature a rapid application development capability: the development kit usually allows devices to be connected over Bluetooth in about 30 minutes. TDK Systems has reduced the application evaluation time as well as removed the need for RF and wireless experience as well as the need for Bluetooth approval: this can save approval costs of approximately €30,000 to €45,000.
In the corporate computing sector, Bluetooth is now being understood and appreciated as a mobile efficiency technology. Bluetooth allows mobile workers to recoup a significant degree of the dead time that travel and roaming workers suffer. Many corporate level users have now learnt that Bluetooth and Wi-Fi are complimentary technologies that do not vie with each other in wireless applications. In fact this always was the case; Bluetooth has emerged strongly in mobile device connectivity allowing efficiency gains from getting mobile devices working better for the mobile worker whereas Wi-Fi is an excellent solution for de-cabling office computers and for static hotspots. Bluetooth has an agreeably low cost of ownership (TCO) and, importantly for this and other sectors, its security implementation has proven to be robust. In a study published in 2003 TDK Systems highlighted not only these factors but the rapid pay-back that the technology rewards business users. TDK Systems is working with corporate scale and business users, developing mobile computing policies to aid recognition and awareness of Bluetooth’s usefulness and value.
Bluetooth moving forward
TDK Systems believes in discovering and maximising the potential of Bluetooth today - rather than hopping to the next technology “lily-pad”. Reflecting on the consumer, corporate and vertical market opportunities TDK Systems continues to differentiate its products and focus on each of these three key areas. The company’s product orientation is on application development – providing software applications that allow users to take advantage of Bluetooth making it a useful, compelling and valuable part of their mobile lives.
Education is an important aspect for the future all wireless technologies. TDK Systems has developed education, information and training products targeted to help all types of users learn about, adopt and develop wireless technologies applications. TDK Systems provides knowledge and targeted information from its B-Informed education portal. At www.b-informed.co.uk the company highlights applications, case studies, white papers and provides technology briefings. As TDK Systems and Bluetooth move ahead, knowledge, awareness and experience remain vital.
