Key Features

WLAN Standards: IEEE 802.11a
IEEE 802.11b
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.AES
OF

Interfaces

Interfaces LAN: 10 Base-T
10/100 Base-T
WAN interfaces: When you buy a router for a long-distance network, remember that this type of network covers a large number of different devices and services. You must therefore choose the interface based on the type of service and the nature and amount of traffic that the network will transmettre.ATM
CSU / DSU

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. The key for the user that the device uses the boNo protocol to communicate with other ordinateurs.ATM

Wireless

Data Rates 802.11a: 54 Mbps, 48 ​​Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, 9 Mbps, 6 Mbps
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
CCK
QPSK
BPSK
DBPSK
DQPSK
16QAM
64QAM
