Comparison of Mobile Internet Access methodes

Common Name	Family	Primary Use	Radio Tech	Downstream (Mbit/s)	Upstream (Mbit/s)	Notes
HSPA+	3GPP	General 4G	CDMA/FDD MIMO	21 84 672	5.8 22 168	HSPA+ is widely deployed. Revision 11 of the 3GPP states thatHSPA+ is expected to have a throughput capacity of 672 Mbps.
LTE	3GPP	General 4G	OFDMA/MIMO/SC-FDMA	100 Cat3 150 Cat4 300 Cat5 (in 20MHz FDD) [31]	50 Cat3/4 75 Cat5 (in 20 MHz FDD)[31]	LTE-Advanced update expected to offer peak rates up to 1 Gbit/s fixed speeds and 100 Mb/s to mobile users.
WiMAX	802.16	Mobile Internet	MIMO-SOFDMA	128 (in 20MHz bandwidth FDD)	56 (in 20MHz bandwidth FDD)	WiMAX update IEEE 802.16m expected to offer peak rates of at least 1 Gbit/s fixed speeds and 100 Mbit/s to mobile users.
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 30km (18 miles) extended range 55 km (34 miles)
HIPERMAN	HIPERMAN	Mobile Internet	OFDM	56.9
Wi-Fi	802.11 (11n)	Mobile Internet	OFDM/MIMO	300 (using 4x4 configuration in 20MHz bandwidth) or 600 (using 4x4 configuration in 40MHz bandwidth)		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: 250km/h Spectral Efficiency: 13 bits/s/Hz/cell Spectrum Reuse Factor: "1"
EDGE Evolution	GSM	Mobile Internet	TDMA/FDD	1.6	0.5	3GPP Release 7
UMTS W-CDMA HSDPA+HSUPA	UMTS/3GSM	General 3G	CDMA/FDD CDMA/FDD/MIMO	0.384 14.4	0.384 5.76	HSDPA is widely deployed. Typical downlink rates today 2 Mbit/s, ~200 kbit/s uplink; HSPA+ downlink up to 56 Mbit/s.
UMTS-TDD	UMTS/3GSM	Mobile Internet	CDMA/TDD	16		Reported speeds according to IPWireless using 16QAM modulation similar to HSDPA+HSUPA
EV-DO Rel. 0 EV-DO 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. EV-DO is not designed for voice, and requires a fallback to 1xRTT when a voice call is placed or received.

There seems to be confusion when people discuss terms like 3.5G, 3.75G so i decided to define them. I am sure people who have objections will comment.

Lets first start with 2G systems:

2G = GSM

2.5G = GPRS

2.75G = EDGE

Then moving onto 3G systems:

3G = WCDMA, R99 (i am not looking at other technologies but similar mapping will apply)
3G+{3.5G = HSDPA, 3.75G = HSUPA

3.8G = HSPA+ (HSPA Enhancements)

3.85G = 'HSPA+' + MIMO
3.9G = LTE

International Spectrum is Currently Used by Countries.

4G = LTE Advanced (NOT WiMAX)

Hi Guys!! have U ever wondered of the mobility communications now a days?
Have u ever been interested to know whats the difference between 3G HSUPA or HSDPA or what is HSPA+?
have you ever asked ur self which one works on 3.5G or which one is a part of 3.75G???
