Key Features

Antenna type: Internal antennas are built into the device. They can not be changed or directed.
External antennas can be oriented in different directions. They are usually used to increase the range of the device.
The detachable antennas are screwed to the device. They can easily be replaced by models puissants.3 external antennas
WLAN Standards: IEEE 802.11n
IEEE 802.11g
Security: All access points are wireless to guarantee a certain level of security to protect access to data you transmit. These are safety standards that the device is conforme.WPA
WPA2

Standards and Protocols

Protocols: The protocols are standard formats for converting data between devices. They determine many aspects of data: error checking, compression types and names of the procedures for sending and retrieving data from the devices. Programmers can choose from a wide variety of standard protocols, each with their advantages and disadvantages. Some are easier than others, some are more reliable and more faster.

Wireless

802.11b data rates: 11 Mbps, 5.5 Mbps, 2 Mbps, 1 Mbps
802.11g data rates: 54 Mbps, 48 ​​Mbps, 36 Mbps, 24 Mbps, 28 Mbps, 12 Mbps, 9 Mbps, 6 Mbps, 5.5 Mbps, 2 Mbps, 1 Mbps
Modulation: There are many standards of modulation. The most commonly used are:

DSSS
The standard DSSS (Direct-Sequence Spread Spectrum) is a transmission technology that combines the data signal to a sequence of data bits higher technique called "chipping." This ensures an increased resistance to noise and better data integrity.

OFDM
The standard OFDM (Orthogonal Frequency Division Multiplexing) is to transmit digital data by radio wave by dividing a radio signal into multiple sub-signals. These signals are then transmitted simultaneously at different frequencies. This modulation technique has the advantage of reducing the crosstalk noise.

CCK
CCK (Complementary Code Keying) uses a sequence of 64 code words 8 bits to encode data. This results in speeds of 5.5 and 11 Mb / s in the 2.4 GHz band of laOFDM
