• Provide 1 to 7 networking structure. Bluetooth standard specification employs 1 to 7 Micronet that allows your PC to connect with up to 7 peripherals or Bluetooth handheld devices (such as cellular phones, PDAs, keyboards, mice, earphones, printers, presenters). Thus, you can form a small wireless network sharing Internet bandwidth or perform local networking operations with the EPoX Bluetooth USB Adapter and other Bluetooth enabled computers.
• Farther transmission distance. Compared with other RF products, Bluetooth adapters can provide farther wireless working range. The standard Class 2 Bluetooth products have transmission distance up to 10 meters while the Class 1 products can reach up to 100 meters
• No line-of-sight restriction. While Infrared products work only via line-of sight transmission, Bluetooth-enabled products eliminate the restriction by its radius wireless communication mode. In addition, Bluetooth devices transmit low-frequency signals that can penetrate nonmetal objects such as desks, chairs, briefcases, clothing, etc., making the wireless applications more practical in both business and home life.
• Superior anti-interference capability. By utilizing frequency hopping technology that reaches 1600 hops per second, adjusting transmission power according to external interference, and adapting the short data packets, which maximizes throughput during interference, Bluetooth devices can maintain a stable connection when confronted with interference in a noisy environment (such as the interference from cellular phones, wireless LAN, microwaves, RF, etc.). This superior interference-free capability guarantees you a clear communication and connection.
• Available with disparate wireless applications. The official Bluetooth specification developed by Bluetooth SIG, which were founded by leading international computer manufacturers, software developing companies, and telecommunication equipment manufacturers, has its mission to realize interoperability between personal digital devices by the use of this uniform wireless interface. Therefore, Bluetooth adapters can establish wireless communication links with a very broad range of devices (such as cellular phones, headsets, MP3 players, PDAs, digital cameras, printers, etc.) Moreover, the connected devices require no any driver programs to set up the connections. Therefore users can employ various wireless applications easily, and are free from the troubles of carrying proprietary cables.
• High security for data transmission. Bluetooth security is enforced with 128-bit encryption, authorization, and authentication, therefore your personal privacy and data security will be better protected.
