Until now, the only way to ensure the presence of a Wi-Fi network is to own a PC or PDA incorporating technology. The SmartID Wi-Fi detector housing provides a simple and inexpensive alternative to this problem. Barely above a pack of cigarettes, but almost twice as close, it is easier to use can not. No need to waste his time reading the Getting Started guide, the transaction is to just push the button and the strength of Wi-Fi signal is displayed, if there is one within range of antenna.
Difficult to make more explicit. The housing comprises a button and five light emitting diodes (LED), a green and four red. The green lights by pressing the power button. Then the red LEDs light up depending on the Wi-Fi signal picked. No LED lit, no signal. The four diodes logically correspond to a maximum current signal. Everything is to let the finger on the start button, the system being devoid of switch on / off. What is all the same tiresome.
That’s the theory, in practice the Wi-Fi detector is more sensitive shows that some Wi-Fi devices that we’ve tested. The Toshiba Pocket PC e750 for example loses signal earlier than the detector. The difference is in the order of two to three meters, but we can still acknowledge the performance.
A signal received by the detector is not synonymous with free internet access. First, the sensor is not able to report a protected network, either by the protocol WEP (Wireless Encryption Protocol) or any other system. It is possible to be in the coverage area without access to the network.
In addition, the Wi-Fi detector responds to all signals in the 2.4 GHz frequency band. Wi-Fi of course, but also Bluetooth, DECT cordless phones … or even the microwave! Do not panic if it finds a network in your kitchen while you reheat a chicken.
