Connectivity: Wireless
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.2 detachable antennas
WLAN Standards: IEEE 802.11b
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.AES
802.1x

Interfaces

Integrated: Integrated Switch 4-port
LAN Interfaces: 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.ADSL over ISDN

Standards and Protocols

StandardsLAN: IEEE 802.3 CSMA / CD or Ethernet
IEEE 802.3u 100 Mbps (Fast Ethernet)
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 correct protocol to communicate with other ordinateurs.ATM

PPPoE
Routing protocols: OSPF
RIP Version 1
RIP Version 2
BGP
EIGRP
Management Protocol: A network protocol is a set of rules, conventions and formal data structures that govern how computers exchange information over a network. Fruit of years of evolution and development, network protocols are defined by many standards organizations and vendors technologiques.SNMP
HTTP
Telnet

Firewall / VPN

VPN tunnels: 20
Firewall Features: SPI (Stateful Packet Inspection)
NAT
VPN Protocols: IPSec Pass-Thru
PPTP Pass-Thru
L2TP Pass-Thru
IPSec
Authentication: RADIUS
TACACS +
VPN Encryption: The standard DES (Data Encryption Standard) is the standard method of data encryption. She uses the key DES56 bits to encrypt and decrypt data.
3DES 168-bit encryption (sometimes called "Triple") is an algorithm that guarantees a higher level of security because it encrypts each data block three times with each time a key unique.3DES

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 advantagereduce 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
