What are high data rates?
HDR is a Qualcomm wireless technology that provides high-speed, high-capacity IP packet data services that carriers can deploy in metropolitan areas. It can provide up to a 2.4-Mbit/sec data transfer rate in a 1.25-MHz channel for use by stationary users, portable devices, and mobile services.
Data rate is the amount of data in bits per second of footage, measured per second and expressed as bits per second. Bit rate is the number of bits per second of footage, measured per frame or field, also expressed as bits per second. The common units for both are: Kbps (or kbps) – Kilo bits per second.
- Bitrate refers to the number of bits—or the amount of data—that are processed over a certain amount of time. In audio, this usually means kilobits per second. For example, the music you buy on iTunes is 256 kilobits per second, meaning there are 256 kilobits of data stored in every second of a song.
- In this context, bitrates refer to the amount of data stored for each second of media that is played. Therefore, the higher bitrate is a general rule, but not 100% true. The same applies to videos – a higher bitrate will have a higher quality when comparing the same video with the same resolution.
- In data communications, bits per second (abbreviated bps or bit/sec) is a common measure of data speed for computer modems and transmission carriers. As the term implies, the speed in bps is equal to the number of bits transmitted or received each second.
The speed with which data can be transmitted from one device to another. Data rates are often measured in megabits (million bits) or megabytes (million bytes) per second. These are usually abbreviated as Mbps and MBps,respectively. Another term for data transfer rate is throughput.
- If either the wireless router or the wireless client can support only 11a or 11g, the link rate would be a maximum of 54 Mbps, and the actual data transfer speed would be about 22 Mbps. The most common 11n maximum link rates are 150 Mbps and 300 Mbps.
- bandwidth: The data transfer rate of a network: measured in kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second (Gbps).
- The original IEEE-1394 standard is known as FireWire, IEEE-1394a, DV or as i.Link® (Sony®'s implementation of the standard). Occasionally it is referenced as FireWire 400 due to its maximum data transfer speed of 400 Mbps.
Video data rates are given in bits per second. The data rate for a video file is the bitrate. So a data rate specification for video content that runs at 1 megabyte per second would be given as a bitrate of 8 megabits per second (8 mbps).

- A benchmark can be used to measure throughput. In data transmission, network throughput is the amount of data moved successfully from one place to another in a given time period, and typically measured in bits per second (bps), as in megabits per second (Mbps) or gigabits per second (Gbps).
