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 Air 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 wireless 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.
*Maximum wireless signal rate based on IEEE Standard 802.11b specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead lower actual data
