High Frequency Internet Protocol

High Frequency Internet Protocol acronyms: HFIP or HF-IP. Usually associated with Automatic Link Establishment and HF radio data communications. HFIP provides protocol layers enabling internet file transfer, chat, web, or email. HFIP commonly uses ionosphere propagation of radio waves to form a wide area network that can span thousands of kilometers. HF transceivers in HFIP service typically run 20 to 150 Watts for portable or mobile units, up to approximately 2000 Watts transmitter output for high power base stations with HFIP servers.

STANAG 5066 is a common HFIP standard.

An amateur radio HFIP network called HFLINK uses Automatic Link Establishment for initiating data communications, with ARQ 8FSK frequency shift keying and PSK phase shift keying signals.

Famous quotes containing the words high and/or frequency:

    Gifts of one loved me,—
    ‘T was high time they came;
    When he ceased to love me,
    Time they stopped for shame.
    Ralph Waldo Emerson (1803–1882)

    The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.
    Jean Marzollo (20th century)
