Standard | Family | Primary Use | Radio Tech | Downlink (Mbit/s) | Uplink (Mbit/s) | Notes |
---|---|---|---|---|---|---|
LTE | UMTS/4GSM | General 4G | OFDMA/MIMO/SC-FDMA | 360 | 80 | LTE-Advanced update expected to offer peak rates of at least 1 Gbit/s fixed speeds and 100 Mbit/s to mobile users. |
வைமாக்ஸ் | 802.16e | Mobile Internet | MIMO-SOFDMA | 144 | 35 | WiMAX update IEEE 802.16m expected offer up to 1 Gbit/s fixed speeds. |
Flash-OFDM | Flash-OFDM | Mobile Internet mobility up to 200mph (350km/h) |
Flash-OFDM | 5.3 10.6 15.9 |
1.8 3.6 5.4 |
Mobile range 18miles (30km) extended range 34 miles (55km) |
HIPERMAN | HIPERMAN | Mobile Internet | OFDM | 56.9 | 56.9 | |
ஒய்-ஃபை | 802.11 (11n) |
Mobile Internet | OFDM/MIMO | 288.9 (Supports 600Mbps @ 40MHz channel width) |
Antenna, RF front end enhancements and minor protocol timer tweaks have helped deploy long range P2P networks compromising on radial coverage, throughput and/or spectra efficiency (310km & 382km). | |
iBurst | 802.20 | Mobile Internet | HC-SDMA/TDD/MIMO | 95 | 36 | Cell Radius: 3–12 km Speed: 250kmph Spectral Efficiency: 13 bits/s/Hz/cell Spectrum Reuse Factor: "1" |
EDGE Evolution | உலகளாவிய நடமாடும் தகவல் தொடர்புகள் திட்டம் | Mobile Internet | TDMA/FDD | 1.9 | 0.9 | 3GPP Release 7 |
உலகளாவிய மொபைல் தொலைத்தொடர்பு அமைப்பு W-CDMA HSDPA+HSUPA HSPA+ |
UMTS/3GSM | General 3G | CDMA/FDD CDMA/FDD/MIMO |
0.384 14.4 56 |
0.384 5.76 22 |
HSDPA widely deployed. Typical downlink rates today 2 Mbit/s, ~200 kbit/s uplink; HSPA+ downlink up to 56 Mbit/s. |
உலகளாவிய மொபைல் தொலைத்தொடர்பு அமைப்பு | UMTS/3GSM | Mobile Internet | CDMA/TDD | 16 | 16 | Reported speeds according to IPWireless using 16QAM modulation similar to HSDPA+HSUPA |
1xRTT | CDMA2000 | Mobile phone | CDMA | 0.144 | 0.144 | Succeeded by EV-DO |
EV-DO 1x Rev. 0 EV-DO 1x Rev.A EV-DO Rev.B |
CDMA2000 | Mobile Internet | CDMA/FDD | 2.45 3.1 4.9xN |
0.15 1.8 1.8xN |
Rev B note: N is the number of 1.25 MHz chunks of spectrum used. |
Notes: All speeds are theoretical maximums and will vary by a number of factors, including the use of external antennae, distance from the tower and the ground speed (e.g. communications on a train may be poorer than when standing still). Usually the bandwidth is shared between several terminals. The performance of each technology is determined by a number of constraints, including the spectral efficiency of the technology, the cell sizes used, and the amount of spectrum available.
