Connect from wherever to wherever with Wi-Fi.
Wi-Fi or WLAN technologies are popular alternatives and supplements to wired networks. The mobility of wireless devices compared with the lightweight laptops, cell phones and other handhelds has provided an undisputable success for the Wi-Fi devices.
So why bother with cables at all?
Even with the latest improvement of the Wi-Fi bandwidth the performance is lagging behind that of its wired cousin, the fast Ethernet.
There are also shortcomings and restrictions the user may have to overcome. Any deviation from the optimal signal strength will trigger a substantial slowdown in the transmission speed.
Besides, Wi-Fi is highly distance sensitive. The performance will slow down significantly, not only as the distance from the laptop to the access point increases, but also obstacles in the line of sight can attenuate the strength of the signal.
However, with an optimal reception a wireless connection will provide a more than acceptable performance for most common purposes.
Wi-Fi has a few more problems that may lower the performance. Not only can WLAN’s encounter interference problems from neighboring networks, but also microwave ovens, cordless phones, Bluetooth devices, and other electronic devices generates RF waves that can degrade the signal.
A professional designer knows of all these problems and can help you to minimize them.
A wireless signal travels through the air much like a light beam, and armed with a simple piece of equipment, anybody within ‘sight’ can intercept the signal. It is therefore critical that the WLAN traffic is secured with an appropriate level of encryption and that access to the configuration is guarded with strong password protection.
