WiMax – Code Curmudgeon

A long-range wireless technology for high-speed internet access. Originally it was classified as a 3G technology, but because of it’s improved performance can also be classified as 4G, albeit slower than LTE. Supported by Sprint in the USA.

CAN (Controller Area Network)

Controller Area Network aka CAN aka CAN Bus is a wiring standard for vehicles that enables communication between various components and devices without having a host computer. For example doors, brakes, transmission.

LTE

LTE or <i>Long Term Evolution</i> is one of the most common methods of supporting high-speed 4G wireless standards. It uses 3GPP technology and can work with both CDMA and FSM. In the USA Verizon and T-Mobile use it, while AT&T have used different 3G hybrid technologies but have planned LTE rollouts.

The 3rd generation of cellular wireless standards. 3G is implemented in a variety of non-compatible ways by various carriers. This includes CDMA, HSPA, and GSM for the most part. Typical performance is required to support peak data rates of 200 kbit/s. Some modern hybrid systems support several Mbit/s.

The 4th generation of cellular wireless standards - it's the successor the 3G. There is a vast difference between how carriers interpret and implement 4G at the current time, ranging from HSPA to WiMax to LTE, each has difference performance characteristics. The standard requires peak data rates from 100 Mbit/s for high mobility to 1Gbit/s for low mobility.
