"Key features of Rev A include:
Improved broadband speeds : Provides a peak data rate of 3.1 Mbps in the forward link and 1.8 Mbps in the reverse link in a 1.25 MHz FDD carrier. In commercial networks, Rev A achieves average throughput of 450-800 kbps in the forward link and 300-400 kbps in the reverse link
Higher spectral efficiency : Supports1.2 times Rel 0 forward link sector capacity and3.4 times reverse link sector capacity. Increased rate quantization on both forward and reverse link enables more efficient use air link resources, better network utilization and lower cost of delivery
Increased Capacity – On both the forward and reverse link, Rev A allows operators to support more users and it improves the cost of delivering voice, data and multimedia services.
Symmetry – By increasing uplink speeds, Rev A is the first commercially available wireless technology to deliver a true synchronic broadband experience. Symmetry is important for applications where users send packets of data as often as they receive them, such as receiving and sending email with attachments.
Low latency : The average latency of Rev A is below 50 milliseconds, making it ideal for delay-sensitive applications.
Advanced Quality of Service (QoS) mechanisms that support the prioritization and delivery of individual packets based on the type of application or user profile. These mechanisms ensure a consistent, high-quality user experience.
All-IP: Internet Protocol (IP) is the foundation for CDMA2000 radio access networks. Like 1xEV-DO Rel 0, All-IP Rev A networks provide operators service flexibility and higher bandwidth efficiencies, which translate into greater control and significant cost savings.
Advanced services : Enables the enhanced performance of real-time broadband, symmetric data link, and delay sensitive services such as VoIP, push-to-talk (PTT), push-to-media (PTM), video conferencing, multicasting, and rich 3D gaming with multiple players.
Backward compatibility: Rev A networks support existing Rel 0 applications and devices. This backward compatibility preserves an operator’s previous network investments. Rev A it is backwards compatible with 1X and cdmaOne systems through multi-mode devices . "
It says avg latency is below 50ms for rev A!!!! What the ef.
Fortunately we managed to locate an unused ADSL line in our office, and will be cancelling.
