Bluetooth is a short range, wireless radio. When Bluetooth-capable devices come within range of one another, an
electronic conversation automatically takes place to determine whether they have data to share or whether one needs
to control the other. Then, the devices hop frequencies in unison so they stay in touch with one another and avoid
interference with other devices. Bluetooth devices send out very weak signals of 1 milliwatt. By comparison, the
most powerful cell phones can transmit a signal of 3 watts. This limits their range to about ten meters. Even with the
low power, the walls in your house won't stop a Bluetooth signal, making the standard useful for controlling several
devices in different rooms.
Antennas
The GoBook VR-2 has several embedded antenna options to support wireless communications.
Improving Radio Coverage
Wireless connectivity between your GoBook VR-2 and wireless network access points is essential. Maintaining this
wireless connectivity over a wide area is fundamental to the usefulness of the network. This makes the scope and
reliability of radio coverage a primary concern. Therefore, one of the most important features of the wireless
network is the degree of radio coverage provided. Coverage can be influenced by terrain, buildings or even a
crowded room. Here are some tips to help you improve radio coverage, depending on your location.
In any Location
1. Performance can vary significantly at different times of the day.
2. Weather can affect performance.
