You're familiar with the benefits of wireless LAN, most importantly convenience but you may have concerns about security and coverage. Even if you don't use a wireless computer yourself, you may be concerned that your colleagues do, and the potential risk that adds to your business. Corporate confidentiality or security could be compromised. All DrayTek wireless routers and access points provide multiple independent methods of security. This includes industry standard encryption, but also device locking ( MAC Address ), wireless VLANs and user authentication. In addition, using a directional aerial can increase range but only in the direction you choose, i.e. into your building.
