Wi-Fi and Security Considerations for ClickShare

Page 10 of 14

Compared to the empirical site survey method, the

deterministic method is usually more convenient and cost-

effective. An optimal configuration can be reached by

simulating different configurations of the environment in which

the network will be deployed. However, an accurate prediction

hereby depends on the availability of data such as the

composition of the obstacles along the signal path and their

corresponding effect on electromagnetic signals (Sarkar et al.,

2003; Iskander & Yun, 2002; Mikas, et al., 2003). In such

cases, site surveying is usually quicker and more accurate.

The IEEE802.3af standard for power over ethernet (PoE) was

developed to facilitate the deployment of WLAN APs in

environments where it is difficult to access power. However,

because it also drives the projector or display and performs

video processing of the incoming video streams, ClickShare is

more than a WLAN AP. Therefore, the ClickShare Base Unit

does not include the PoE capability.

We suggest that SSID broadcasting be switched off for normal

use. Note that the factory activates SSID broadcasting to

facilitate installation. It is then up to the integrator to switch it

off for first use.

A WLAN controller is a device that provides centralized

management and control of a collection of lightweight APs. The

ClickShare Base Unit is neither a WLAN controller nor a

lightweight AP, and so it cannot be operated as such.

ClickShare is a closed system and is not intended to

interoperate with other, more general purpose, APs. Therefore,

we strongly recommend the following:

• Use IEEE802.11n mode in the 5GHz frequency

range,

• Set WPA2 protection with a strong password, and

• Switch off SSID broadcasting.
