User Equipment (UE) Categories
3GPP Release 8 defines five LTE user equipment categories depending on maximum peak data rate and MIMO capabilities support. With 3GPP Release 10, which is referred to as LTE Advanced, three new categories have been introduced.
| 3GPP Release | User Equipment Category | Maximum L1 datarate Downlink | Maximum number of DL MIMO layers | Maximum L1 datarate Uplink |
|---|---|---|---|---|
| Release 8 | Category 1 | 10.3 Mbit/s | 1 | 5.2 Mbit/s |
| Release 8 | Category 2 | 51.0 Mbit/s | 2 | 25.5 Mbit/s |
| Release 8 | Category 3 | 102.0 Mbit/s | 2 | 51.0 Mbit/s |
| Release 8 | Category 4 | 150.8 Mbit/s | 2 | 51.0 Mbit/s |
| Release 8 | Category 5 | 299.6 Mbit/s | 4 | 75.4 Mbit/s |
| Release 10 | Category 6 | 301.5 Mbit/s | 2 or 4 | 51.0 Mbit/s |
| Release 10 | Category 7 | 301.5 Mbit/s | 2 or 4 | 102.0 Mbit/s |
| Release 10 | Category 8 | 2998.6 Mbit/s | 8 | 1497.8 Mbit/s |
Note: These are L1 transport data rates using 20 MHz of bandwidth, not including the different protocol layers overhead. With 10 MHz of spectrum, maximum downlink data rates are 73 Mbps with 2x2 MIMO and 147 Mbps with 4x4 MIMO, and upstream 36 Mbps. With 5 MHz of spectrum, downlink is 37 Mbps and 72 Mbps respectively, and upstream 18 Mbps.
Note: The 3.0 Gbit/s / 1.5 Gbit/s data rate specified as Category 8 is near the peak aggregate data rate for a base station sector. A more realistic maximum data rate for a single user is 1.2 Gbit/s (downlink) and 600 Mbit/s (uplink). Nokia Siemens Networks has demonstrated downlink speeds of 1.4 Gbit/s using 100 MHz of aggregated spectrum.

Famous quotes containing the words user, equipment and/or categories:
“A worker may be the hammer’s master, but the hammer still prevails. A tool knows exactly how it is meant to be handled, while the user of the tool can only have an approximate idea.”
—Milan Kundera (b. 1929)
“Why not draft executive and management brains to prepare and produce the equipment the $21-a-month draftee must use and forget this dollar-a-year tommyrot? Would we send an army into the field under a dollar-a-year General who had to be home Mondays, Wednesdays and Fridays?”
—Lyndon Baines Johnson (1908–1973)
“all the categories which we employ to describe conscious mental acts, such as ideas, purposes, resolutions, and so on, can be applied to ... these latent states.”
—Sigmund Freud (1856–1939)
