EVOLUTION OF WIRELESS APPLICATIONAleksejs JurenoksRiga Technical University,1, Kalku Street, Riga LV-1658, LatviaE-mail: ajurenoks@rsdc.lvKEYWORDSWireless network, mobile solution, quality of serviceABSTRACTThe <strong>in</strong>troduction of wireless communication isdramatically chang<strong>in</strong>g our lives. The ability tocommunicate anytime anywhere <strong>in</strong>creases our quality oflives and improves our bus<strong>in</strong>ess productivity. The recenttechnological developments that allow us to executebandwidth-hungry multimedia applications over thewireless media add new dimensions to our ability tocommunicate. This opens an array of excit<strong>in</strong>gopportunities <strong>in</strong> bus<strong>in</strong>ess, residential, healthcare,education, leisure, and many other areas. Wirelessvideoconferenc<strong>in</strong>g will connect us with bus<strong>in</strong>ess partnersand family members. Remote video medical consultationwill enhance care <strong>in</strong> rural areas and at the accident scene.Interactive games that <strong>in</strong>clude video and graphics withpartners over the globe will add new dimensions not onlyto our leisure opportunities but also to provision<strong>in</strong>g of aneffective remote learn<strong>in</strong>g environment.INTRODUCTIONOver the last ten years, the impact of wirelesscommunications on the way we live and do bus<strong>in</strong>ess hasbeen surpassed only by the impact of the Internet. Cellphones, pagers, and wireless Personal Digital Assistants(PDAs) have become so commonplace <strong>in</strong> our lives that itis easy to forget that ten years ago, they were a rarity. Butwireless communications is still <strong>in</strong> its <strong>in</strong>fancy, and thenext stage of its development will be <strong>in</strong> supplement<strong>in</strong>g orreplac<strong>in</strong>g the network <strong>in</strong>frastructure that was traditionally“wired” as well as enabl<strong>in</strong>g network <strong>in</strong>frastructures thatpreviously could only be imag<strong>in</strong>ed. From local coffeeshops to commercial <strong>in</strong>ventory control systems, with<strong>in</strong>restaurants and throughout public airports, access<strong>in</strong>gcentral pools of <strong>in</strong><strong>format</strong>ion and communicat<strong>in</strong>g directlybetween users and among the devices themselves,wireless commerce is beg<strong>in</strong>n<strong>in</strong>g to challenge theexchange system that our modern world currentlyembraces.No longer are we restricted by the shortfalls ofprocess<strong>in</strong>g and battery power, operat<strong>in</strong>g systemefficiencies, or heat dissipation with<strong>in</strong> the small footpr<strong>in</strong>tof the mobile device. Rather, we are limited only by thepractical application of these technologies. How will weaccess <strong>in</strong><strong>format</strong>ion? How will we <strong>in</strong>tegrate multiplehardware and software technologies <strong>in</strong>to <strong>in</strong>telligent anduseable form factors? Not all bus<strong>in</strong>ess models necessarilyimply the use of a s<strong>in</strong>gle term<strong>in</strong>al to supply the user withvoice, video, and data services. Ergonomic factors maydictate that voice services are ma<strong>in</strong>ta<strong>in</strong>ed privately whiledata exchange and video <strong>in</strong><strong>format</strong>ion is easily viewablefrom a specified distance, perhaps on complementarydevices.EVOLUTION OF WIRELESS MULTIMEDIAAPPLICATIONThe landscape of Internet usage is dramaticallychang<strong>in</strong>g because of the rapid evolution of access towireless communication with its associated mobility.Consumers <strong>in</strong> both bus<strong>in</strong>ess and residential markets arebecom<strong>in</strong>g <strong>in</strong>creas<strong>in</strong>gly dependent on ubiquitous access.Such access is enabled by the proliferation of wirelesscommunication. Consumers realize the benefits of manynew bus<strong>in</strong>ess applications such as those <strong>in</strong> e-commerce,collaboration, supply cha<strong>in</strong>, and telemedic<strong>in</strong>e. They alsostart to appreciate the benefits for their family andpersonal needs such as communication with friends,enterta<strong>in</strong>ment, gam<strong>in</strong>g, and location and safety services.As the speed and quality provision<strong>in</strong>g of wirelesscommunication <strong>in</strong>crease, consumers' dependency onapplications delivered through the wireless media will<strong>in</strong>crease. They will also enjoy improved graphics as thewireless media will be able to deliver content-richapplications through their higher speed wirelessnetworks.This new era of ubiquitous wireless communicationwill provide an array of applications supported by theability to access the Internet everywhere and anytime.Wireless communication will be available at home and atthe office. Other types of global networks are envisionedonce high-speed 3G cellular phones become available byTELE2 (Latvia) company.Some of the applications that currently use wirelessnetworks as their transmission media were previouslyavailable via wired media and some applications are new.Here is a partial list of these applications:• Stream<strong>in</strong>g videoAnnual <strong>Proceed<strong>in</strong>gs</strong> of Vidzeme University College “ICTE <strong>in</strong> Regional Development”, 2006124
