The term wireless router refers to a type of device that allows for the connection of multiple computers or hardware devices through a network to a single Internet access point without cabling.
The only difference between a wired and wireless router is the cabling. Both of them act as Layer 3 gateways. This simply means the device for instance, provides a connection between networks and thus acts a gateway and at the same time operates at a network level.
The wireless router is especially suited for home of small office networks where it connects the computers on the local area network called LAN to the Internet. It also has the function of filtering incoming and outgoing traffic according to IP addresses. The Draytek devices provide a combination of functions which include acting as firewalls and network switches.
The user has all the advantages of a normal router/modem, but also has the benefit of secure access from an external Virtual Private Network (VPN) client to the LAN. This means that several sites can be linked together through the use of a secure VPN channel or tunnel. Home office workers who are telecommuting can thus access their company’s data from home without expensive cabling between the office and home or having to lease a line from a service provider.
It also means that you can access your LAN from anywhere through the Internet. This definitely increases productivity and reduces communication costs. Not all router/modems come standard with VPN access points. Several of the Draytek products however, include the VPN facilities, which make remote access to data in a secure environment possible.
Special security features such as data encryption and IP encapsulation help to prevent hacking into the network. Secure keys also ensure a safer communication environment. User authentication and Network Address Translation (NAT) features furthermore provide additional security_ NAT converts your public IP address to a private address.
Multi-in-and-out features allow for faster transmission of data in both directions; meaning sending and receiving of data faster than would normally be the case. Automatic switching to the best available channel ensures that there are no blockages, noise or interference while data is transmitted. If you use a Draytek product you can for example, connect all the computers in your warehouse without having long cables.
