Circuit Switched Data
... Circuit Switched Data (CSD) is the original form of data transmission developed for the time division multiple access (TDMA)-based mobile phone systems like ... CSD uses a single radio time slot to deliver 9.6 kbit/s data transmission to the GSM Network and Switching Subsystem where it could be connected through the equivalent of a normal modem to the ... Prior to CSD, data transmission over mobile phone systems was done by using a modem, either built into the phone or attached to it ...
Internet In The United Kingdom - Broadband - Digital Subscriber Line (DSL) - Max and Max Premium
... Both Max services offer downstream data rates of up to 7.15 Mbit/s ... Upstream data rates are up to 400 kbit/s for the standard product and up to 750 kbit/s for the premium product ... Whilst the maximum downstream data rate for IPStream Max is often touted as 8 Mbit/s, this is in fact misleading because, in a departure from previous practice, it actually refers to the ...
Chirp Spread Spectrum - Uses
... originally designed to compete with ultra-wideband for precision ranging and low-rate wireless networks in the 2.45 GHz band ... low power usage and needing relatively low data rates (1 Mbit/s or less) ... In particular, IEEE 802.15.4a specifies CSS as a technique for use in Low-Rate Wireless Personal Area Networks (LR-WPAN) ...
Wlan - History
... The first generation of wireless data modems was developed in the early 1980's by amateur communication groups ... They added a voice band data communication modem, with data rates below 9600 bps, to an existing short distance radio system such as a walkie talkie ... These modems provided data rates on the order of hundreds of Kbps ...
Internet Access - Data Rates
... The bit rates for dial-up modems range from as little as 110 bit/s in the late 1950s, to a maximum of from 33 to 64 kbit/s (V.90 and V.92) in the late 1990s ... Data compression can boost the effective bit rate for a dial-up modem connection to from 220 (V.42bis) to 320 (V.44) kbit/s ... However, the effectiveness of data compression is quite variable, depending on the type of data being sent, the condition of the telephone line, and a number of other factors ...

Famous quotes containing the words rates and/or data:

    [The] elderly and timid single gentleman in Paris ... never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.
    Henry Brooks Adams (1838–1918)

    To write it, it took three months; to conceive it three minutes; to collect the data in it—all my life.
    F. Scott Fitzgerald (1896–1940)
