Since your voice and data transmissions pass every other house connected to the coax cable, security is a major concern in the absence of an effective encryption mechanism Third, much like 10Base5 Ethernet and very much unlike DSL, the CATV local loop network is shared Therefore, the more active users are on the network, the worse the performance While the CATV providers speak of total bandwidth of as much as 500 Mbps and user access at rates of as much as 10 Mbps, those are best case gures quoted on the assumption that the load on the shared medium is light enough to support transmission rates of 10 Mbps for all active users DOCSIS cable modems work on an asymmetric basis, as do most xDSL options.

Speci cally, the maximum aggregate usable bandwidth of a downstream channel currently is 31 Mbps, and the maximum aggregate usable upstream bandwidth ranges from 200 kbps to 100 Mbps, depending on the speci cs of the eld implementation of a network conforming to DOCSIS 11 speci cations Especially with the strength of AT&T (ie, AT&T prior to the merger with SBC) behind it, it seemed as though CATV network providers had an excellent chance of securing a large segment of the market for high-speed Internet access The CATV providers did, indeed, enjoy considerable success, although nancial problems caused AT&T Broadband to merge with (read be acquired by) Comcast in 2001, only two years after it was formed About the same time, AT&T s primary ISP, At Home Corp.

The direction of the light is important because it determines where shadows fall. The shadows are what create depth in a photo, and if the direction isn t just right, you should either move the subject to change the direction of the light or wait for the light to move. The direction of the light can either bring out the details in your subject or hide them. Light can hit a subject in four distinct directions.

, ceased operations, and its Excite@Home customers were left stranded for several days until AT&T and other CATV providers managed to switch them to their in-house ISP networks Since that time, Comcast and other CATV providers in the United States have enjoyed tremendous success According to the Telecom-.

The temporal variability of wireless channels has an impact on whether the channel can be identi ed (measured) in a unique way. A band-limited time-invariant channel can always be identi ed by appropriate measurement methods, the only requirement being that the RX ful lls the Nyquist theorem [Proakis 2005] in the delay domain i.e., samples the received signal suf ciently fast. In a time-variant system, the repetition period Trep of the sounding pulse p(t) is of fundamental importance. The channel response to any excitation pulse p(t) can be seen as one snapshot (sample) of the channel (see Figure 8.2). In order to track changes in the channel, these snapshots need to be taken suf ciently often. Intuitively, Trep must be smaller than the time over which the channel changes. This notion can be formalized by establishing a sampling theorem in the time domain. Just as there is a minimum sampling rate to identify a signal with a band-limited spectrum, so is there a minimum temporal sampling rate to identify a time-variant process with a band-limited Doppler spectrum. Thus, the temporal sampling frequency must be twice the maximum Doppler frequency max : frep 2 max (8.5)
