Many phone carriers advertise impressive GPRS connection speeds. In reality, while GPRS standard allows for such speeds, most carriers limit your download rates, so the actual speed is slower. Unlike the PING command which is a common way of measuring connection speed with ICMP packets, BMeter downloads stream of data over a TCP connection, just like you do when talking to your mail or web server. Performance of TCP connections depends on many factors: packet loss, TCP window size, PPP protocol overhead, etc. By using TCP, BMeter simulates the real-life performance of typical networking applications on your Palm.
