Disadvantage Of Cable Modem Networking
Connection instability: One of the supposed advantages that circulate around this type of connections is that they are very stable, more than the ADSL. This is not true at all. Let's see, the transmission of this data depends on the same network that serves mobile phones, and is subject to exactly the same coverage and interference problems as these. It is true that in areas with very good coverage there are no problems, but ... Who has not ever run out of it on the mobile? But not only is this, is that at the moment when the signal is bad for 3G transmissions, it automatically goes to GPRS, with the consequent loss of speed (the maximum attainable speed in data transmission by GPRS is 115 Kbps). It is true that these connections are not influenced by the state of the line (copper pair),
Lack of coverage: This theme links in part with the previous one. We have talked about the advantages of the enormous mobility that have this type of connections compared to traditional ADSL, even if they are Wifi ... but this is, of course, as long as we have coverage, and I repeat, who has not stayed any time without mobile coverage? In addition, contrary to what happens with ADSL connections, which are not influenced by problems of voice line saturation, in the case of 3G connections this does occur, and before saturation in the repeater from which the signal that we are using either will significantly lower the speed or we will lose the connection. In addition, not all signal repeaters are ready to offer 3G connections, and less HSDPA. I know that many will say that they have no problem,
High latency: The latency time on a 3G or HSDPA connection is longer than an ADSL line or cable. This is not usually very important for browsing or instant messaging services, but for other uses, such as online games.
