Point-to-Point Tunneling Protocol (PPTP)
PPTP uses proprietary means of connecting two private networks over the
Internet. PPTP is a way of securing the information that is communicated
between networks. PPTP secures information by encrypting the data inside
of a packet.
IP Security (IPSec)
IPSec provides a more secure network-to-network connection across the
Internet or a Wide Area Network (WAN). IPSec encrypts all
communication between the client and server whereas PPTP only encrypts
the data packets.
Both of these VPN implementations are used because there is not a
standard for VPN server software. Because of this, each ISP or business
can implement its own VPN network making interoperability a challenge.
Introduction to Wireless Networking
D-Link wireless products are based on industry standards to provide
easy to use and compatible high-speed wireless connectivity within your
home or business. Strictly adhering to IEEE 802.11b the D-Link wireless
family of products will allow you to access the data you want, when and
where you want it. No longer will you be tethered to a workstation or
forced to run new wiring. You will be able to enjoy the freedom that
wireless networking delivers.
Standards Based Technology
Based on IEEE 802.11b, D-Link Air products can throughput data up
to 11 Megabits per second. This means you will be able to transfer large
files quickly or even watch a Movie in MPEG format over your network
without noticeable delays. This technology works by using multiple
frequencies in the 2.4GHz range utilizing Direct Sequence Spread
Spectrum (DSSS) technology. D-Link Air products will automatically
sense the best possible connection speed to ensure the greatest speed and
range possible with the technology.
