ZTE Announces First EV-DO Revision B on CDMA2000 System
February 24, 2009 12:17 PM | Technology | Comments (0)
 EV-DO is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. It was designed as an evolution of the CDMA2000 (IS-2000) standard that would support high data rates and could be deployed alongside a wireless carrier's voice services. It is standardized by 3rd Generation Partnership Project 2 (3GPP2) as part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers worldwide, particularly those previously employing CDMA networks. |
The company has completed the first stage of achieving EV-DO Rev.B and adopted 3-carrier bundling technology, with each carrier having a bandwidth of 1.25 MHz. Compared with mature commercial EV-DO Rev.A, what ZTE's EV-DO Rev.B does is to only upgrade EV-DO Rev.A's software, with no additional hardware equipment required. Both ZTE's EV-DO Rev.A and Rev.B adopt identical baseband chipset.
ZTE plans to commercialize its EV-DO Rev.B system in Q3 2009, reaffirming its leading position in EV-DO technology development.
In future, EV-DO Rev.B can bundle up to a maximum of 15 carriers, with a download (forward) rate of 73.5 Mbps and an upload (reverse) rate of 27 Mbps. Among the unique features of EV-DO Rev.B include allocating flexible bandwidth and offering better QoS, hence enhancing user experience.
