The 900 MHz is a longer wave than 2.4 GHz, and penetrates obstructions much better. The XPress Ethernet Bridge is designed to work at a low data rate (1.54 Mbps over-the-air and 1.0 Mbps streaming) at long distances (1000-2000ft indoors and up to 15 miles outdoors, line of sight). Some tests have shown 802.11g working indoors much farther than 300ft, but with reduced throughput to about 1.0 Mbps. ![]() It is interesting to note that after 300ft the link is not necessarily broken. The speed of the 54 Mbps connection drops significantly indoors and nearly dies out at 300 feet. For long distances the 2.4 GHz wave is smaller and does not penetrate obstructions as well as other ISM band frequencies, such as 900 MHz. ![]() 802.11g''''s primary function is to transfer data at high speeds (54 Mbps over-the-air and 35 Mbps streaming) at a short range (<300 ft indoors).
