Key Features

Type: A wireless access point is a device that is used to transmit a wireless online connection and allows users to log on without the inconvenience of a wired network. Wireless bridges are designed to connect multiple networks between wireless access eux.Point
WLAN Standards: A device supports a number of wireless standards, that indicate the features of this device, and the standards that the wireless adapter itself must take charge.IEEE 802.11a
IEEE 802.11g / b
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.WEP
WPA
TKIP
MAC address filtering Wireless

Other Features

802.11a Data Rates: Data rates supported by the device using this type of connection. A single device can support multiple rates données.54 Mbps, 48 ​​Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, 9 Mbps, 6 Mbps
802.11b Data Rates: Data rates supported by the device using this type of connection. A single device can support multiple rates données.11 Mbps, 5.5Mbps, 2 Mbps, 1 Mbps
802.11g Data Rates: Data rates supported by the device using this type of connection. A single device can support multiple rates données.108 Mbps, 54 Mbps, 48 ​​Mbps, 36 Mbps, 24 Mbps, 28 Mbps, 12 Mbps, 9 Mbps, 6 Mbps, 5.5 Mbps, 2 Mbps, 1 Mbps
Operating Frequency: 802.11b and 802.11g standards use the 2.4 GHz signal frequency, which achieves high data rates with longer spans. The WLAN at 2.4 GHz are sometimes subject to interference from cordless phones, microwaves and other WLAN. The 802.11a standard uses for its part, the frequency of 5 GHz signal, which, besides providing a much broader spectrum, is relatively susceptible to interférences.2, 4 GHz
5 GHz
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. Thesesignals 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

WEP Encryption Length: WEP data encryption, as defined by the 802.11 standard, is used to build a network of two main security features: the first is to prevent unauthorized persons can access the network using a similar wireless LAN equipment. The second is to prevent unauthorized traffic on the LAN. WEP works on the following principle: the administrator can define "key" for each user of the wireless network and access is denied to all persons who have no clé.40 bits (= 64 bits)

Antenna Type: Access Points Wireless are provided with 1 or 2 antennas. There are several types of antennas.

Internal
The internal antennas are incorporated into the device. They can not be changed or oriented in a specific direction.

External
External antennas can be oriented in different directions. They are usually used to increase the range of the device.

Removable
The detachable antennas are screwed to the device. They can easily be replaced by models puissants.1 internal antenna / integrated
