Ultra Mobile Broadband(UMB)

This OFDMA-based air interface feature of the CDMA2000 mobile phone allows users to work within OFDMA technology standards by implementing various antenna strategies that are used within several applications. These techniques provide potential peak rates upward of 280 million bits per second. With a bandwith of nearly 20MHz, Ultra Mobile Broadband works to improve a system's capacity by increasing the amount of data that runs throughout it. UMB offers data speed capabilities of nearly 275 M bits per second downstream as well as 75 upstream.

UMB 101

Ultra refers to the speed in which the technology supports a specific increase in data transmission. This speed is associated with the rate in which various forms of online media i.e. voice, entertainment, IT, multimedia, broadband and consumer electronics are delivered.

Mobile defines the support feature of many different wireless services that offers users a full-flow online environment. Some of the wireless services available include: UWB, Wi-Fi and WiMAX.

Broadband explain the high speed capability of the UMB service. This speed is calculated by order of hundreds of megabits per second.

What's Included in UMB

UMB offers increased user data rates by utilizing a management system that will accommodate different services. Through a high RL sector, these services are available through various L1 and L2 handoffs throughout the system. By implementing various FL antenna method techniques, users are offered a reduced amount of interuptted service. Through various power control techniques, this user data interface offers a CDMA control channel through a low-signal service. With a relatively new IP structure support, various inter-technology handoffs are offered to its users. This multi-carrier acquisition allows for a real-time service through a series of wideband devices.

This energy-conserving method enhances one's existing connection and thus, lowering the overall cost. This effective feature helps to expand other technological opportunities as well. UMB offers a complete mobile environment by providing its users with coexisting IP-based services. This standard will begin mid 2007 and will continue to grow through 2009. Ultra Mobile Broadband offers various tradeoffs with existing technologies including: 1xEV-DO and CDMA2000 1X. UMB supports both macro and mirco cellular cells through central topologies.

Why UMB Works

This high bandwidth technology incorporates an existing TCP/IP network that allows for a near impossible application offering. This high quality service has help to improve bandwidth network capabilities as well as increased the efficiency of the overall service. With a larger, better capacity, UMB infuses a breathing phenomenon within it. This concept involves the increased difficulty of microcell additions within the service as well as limits the overall bandwidth availablity to various handset users.
