Top Engineering Colleges in India EC Scholars Explained UMB Features UMB or Ultra Mobile Broadband is the coming revolution of CDMA2000 type of cellular or mobile communication system that runs under auspices as 3GPP2. The latest system promises to deliver relatively fast data transferring speeds and allow the device to compete with various other types of mobile broadband systems, like Wi-Fi and WiMax. EC scholars of top engineering colleges in India said that UMB performs its functions with the prime objective to bring significant increase in the data rates used by users while comparing to already existing CDMA 2000 cell phone technologies. Furthermore, UMB leads to increase in overall capacity of a system, lowers cost associated with one bit of transferring data, enhancements to already existing solutions, creating possibilities for many new applications and ability of using latest spectrum opportunities. Features and Techniques Offered by the System UMB or Ultra Mobile Broadband mobile communication systems provide many innovative techniques and features to satisfy high expectations of people and to allow competing with various other emerging technologies. According to scholars of top engineering colleges in India, •
UMB allows increase in data rates to more than 275 M bits per second in downlink or base station to mobile and about 75 M bits for one second in uplink i.e. mobile to base station.
•
Latest cellular communication system uses air interface as OFDMS or OFDM and FDD called as Frequency Division Duplex.
•
Advanced version of CDMA2000 as UMB incorporates IP networked architecture and scalable frequency range or bandwidth that starts from 1.25 MHz and reaches maximum 20MHz.
•
Lastly, UMB supports distributed, flat and mixed type of network architectures.
Therefore, UMB cellular system will play its major role in providing drastic leap based on capability as compared to already existing CDMA2000 systems.
