    (an initiative to assemble/develop the cheapest, easiest to setup, easiest to manage, scalable, Open Source, standards-based, wireless local do-it-yourself telephone company toolkit in the world)
    asterisk = Asterisk is a software implementation of a telephone private branch exchange (PBX) originally created in 1999 by Mark Spencer of Digium. Like any PBX, it allows attached telephones to make calls to one another, and to connect to other telephone services including the public switched telephone network (PSTN) and Voice over Internet Protocol (VoIP) services. Its name comes from the asterisk symbol, "*".
    DSP = Digital Signal Processing (http://www.dsptutor.freeuk.com/intro.htm)
    ATA = Analog Telephony Adapter
    AP = (Wireless) Access Point
    Mesh Potato is the name of a piece of wireless telephony hardware and software that doesn’t exist yet. It is a marriage of a low-cost wireless access point (AP) capable of running a mesh networking protocol and an Analog Telephony Adapter or ATA. The name Mesh Potato came from combining Mesh with POTS (Plain Old Telephone Service) and ATA
    OpenWrt =
    WRT = Wireless Router
    IP PBX = An IP (Internet Protocol) PBX (Private branch exchange) is a business telephone system designed to deliver voice over a data network and interoperate with the normal Public Switched Telephone Network (PSTN)
    With a conventional PBX, separate networks are necessary for voice and data communications. One of the main advantages of an IP PBX is the fact that it employs converged data and voice networks. This means that Internet access, as well as VoIP communications and traditional telephone communications, are all possible using a single line to each user. This provides flexibility as an enterprise grows, and can also reduce long-term operation and maintenance costs. Like a traditional PBX, an IP PBX is owned by the enterprise.

    VOIP = Voice Over Internet Protocol
    SIP = Session Initiation Protocol (a signalling protocol, widely used for setting up and tearing down multimedia communication sessions such as voice and video calls over the Internet)
    ubiquity nanostation =
    UNIVERSAL INFORMATION AND COMMUNICATIONS TECHNOLOGY
    cybercafe = private

    DSP = Digital Signal Processing (http://www.dsptutor.freeuk.com/intro.htm)
    A digital signal consists of a stream of numbers, usually (but not necessarily) in binary form. The processing of a digital signal is done by performing numerical calculations ...
    In many cases, the signal of interest is initially in the form of an analog electrical voltage or current, produced for example by a microphone or some other type of transducer. In some situations, such as the output from the readout system of a CD (compact disc) player, the data is already in digital form. An analog signal must be converted into digital form before DSP techniques can be applied. An analog electrical voltage signal, for example, can be digitised using an electronic circuit called an analog-to-digital converter or ADC. This generates a digital output as a stream of binary numbers whose values represent the electrical voltage input to the device at each sampling instant
    DSP technology is nowadays commonplace in such devices as mobile phones, multimedia computers, video recorders, CD players, hard disc drive controllers and modems, and will soon replace analog circuitry in TV sets and telephones. An important application of DSP is in signal compression and decompression. Signal compression is used in digital cellular phones to allow a greater number of calls to be handled simultaneously within each local "cell". DSP signal compression technology allows people not only to talk to one another but also to see one another on their computer screens, using small video cameras mounted on the computer monitors, with only a conventional telephone line linking them together. In audio CD systems, DSP technology is used to perform complex error detection and correction on the raw data as it is read from the CD....
