High Quality Content by WIKIPEDIA articles! The AMPRNet (AMateur Packet Radio Network) is an effort by amateur radio operators to build a computer network connected over amateur radio. Other names for the network include IPv4 Network 44/8 and Network 44. Amateur radio already used TCP/IP on packet radio network, long before the appearance of the public Internet. The class A 44 netblock of 16.7 Million IP addresses was set aside for amateur radio users worldwide, having been secured in the 1970s by Hank Magnuski, when the internet was in its infancy. The AMPRNet is connected by links over amateur packet radio. Due to the bandwidth limitations of the radio spectrum, links are usually restricted to a maximum of 9600 baud and are commonly 1200 baud and on occasion as low as 300 baud. The AMPRNet fully supports TCP/IP allowing for support of FTP, telnet, ping, finger and HTTP. Recently the AMPRNet has gained radio link speeds upwards of 108 Mbit/s using HSMM.
