The three most commonly used satellite frequency bands are the C-band, Ku-band, and Ka-band. C-band and Ku-band are the two most common frequency spectrums used by today s satellites. To help understand the relationship between antenna diameter and transmission frequency, it is important to note that there is an inverse relationship between frequency and wavelength when frequency increases, wavelength decreases. As wavelength increases, larger antennas are required to receive the signal. C-band satellite transmissions occupy the 4 to 8 GHz frequency ranges. These relatively low frequencies translate to larger wavelengths than Ku-band or Ka-band. These larger wavelengths of the C-band mean that a larger satellite antenna is required to gather the minimum signal strength. The minimum size of an average C-band antenna is approximately 2 3 meters in diameter as shown in Figure 24-2 .

SIP and SDP make a wonderful partnership for the transmission of session information. SIP provides the messaging mechanisms for the establishment of multimedia sessions and SDP provides a structured language for describing those sessions. The message body in SIP, identified by the entity headers, provides a neat slot where SDP can be used. It is this usage that this section will discuss. SIP uses SDP in an offer/answer model. The initiator of a session offers a selection of media formats to be used in the session. The receiver of the offer either rejects the offer completely or selects those media formats that have been offered and which the responder is willing to accept. If the

Now apply some calculus analysis. The first derivative of the function is, using the quotient rule:

Engine A subset of a computer program that performs a particular task, usually on an ongoing basis. Engines are designed in such a way that they can be used in several different games, thus saving the cost of redeveloping that part of the code for each game. The most common types of engines are graphics engines (which display 3-D spaces on the screen) and physics engines (which compute the behavior, including collisions) of moving objects in a 3-D space. Some development companies license their engines to other development companies to allow them to make games more quickly. Executable

When users run a report, the object with the dynamic link to a web site address is displayed as a hyperlink. As long as you set the object format in Designer as Read As HTML, Desktop Intelligence users can access the web site by clicking the link. For Web Intelligence users, though, they must specifically format the cell to read the data as a hyperlink. In the screen shown here, you also see the correctly formatted web site address that will take you to the web site for the city of Leeds (www.leeds.co.uk).
