The wireless data industry is changing daily. It is becoming incredibly difficult for the wireless professional to stay updated on emerging technologies and trends. Between at home wireless applications, emerging third generation wireless concepts and incredible new products, wireless data is rapidly evolving. This 2- Day course is designed to introduce the student to the major technologies being utilized by wireless carriers to transport data services. The primary focus is on the three major Second Generation competing carrier-based technology systems: CDMA, GSM and iDEN, but basic TDMA is also briefly discussed. While the basic carrier technologies are a baseline, this course will run through all generations of technology growth including 1G, 2G, 3G, 4G, and beyond. A major component of this course is the open forum for questions and discussion on current and future trends in the wireless arena.
This training enables the participants to understand cell planning including frequency planning and traffic dimensioning. Participants will create a nominal cell plan and gain a basic understanding of the various radio network features.
With more advanced handsets and faster network connections, MMS (Multimedia Message Service) is set to succeed SMS as the next big thing in the mobile data services world.
MMS is the evolution of SMS, Short Message Service, which is currently moving toward the exciting Enhanced Message Service (EMS) for illustrated text messages.
MMS can transmit messages containing text, graphics, photographic images, audio and even video clips between mobile devices using Wireless Application Protocol (WAP) as bearer technology and powered by the high-speed transmission technologies.
