There are several phone types as well as phone systems Chicago types. There may be some that are curious as to what these things are on a much deeper level. To those interested, there are at least three main types that may be discussed further. One is the internet protocol variant, another is the plain old telephone service and then there would be cellular phone systems.

The landline system that is still being widely utilized in households and offices today are actually part of the POTS or the plain old telephone service. This is the analog service that has copper wiring. It can be said to be a direct descendant to the system that was originally developed by Alexander Graham Bell.

There are actually several advantages to the use of this variant. Some of the advantages would include having standardized equipment and predictable sound quality. Because of its direct connection to the central office of the company, there exists no need to share its capacity with anyone else who may be in need of it.

All of the switches are already set in place. This creates private circuits for every phone call that is made. Because of that, many refer to it as Public Switched Telephone Network or PSTN. This is something that has been available and used for many decades, even after other variations have risen with all the improvements of technology. Its use has not yet falter in a significant manner.

The second type is utilized heavily by cellular phones. Companies can occasionally have networks that are exclusive to them. Simultaneously, what they have will vary in terms of the type and how far off their technology is. It is comparable to POTS, since it is a full duplex system. That means those on both lines may talk and listen simultaneously.

Despite its similarity, there also exists a notable difference. Such a difference comes in the form of radio frequencies, which is utilized in this variation rather than copper wire. These things started out exclusively as a mobile voice network, they are basically incapable of carrying voice and data at the same time.

Some networks are operating on a national scale. Others are even operating internationally, and one of the best parts is that new technologies are frequently being developed. 3G is known support not only cell phones, but smartphones as well, together with netbook computers and wireless modem aircards.

Voice over internet protocol or VoIP is also called IP. This is another example of what is used today. This service piggy backs existing connections like DSL or cable services. An analog telephone adapter also serves as the mediator that connects a phone to the modem or the router.

This system can be set up with the utilization of just one line for both telephone and internet services. This is how some people save up on expenses. Rather than set up for data or voice, T1 lines can be used as a method of handling both. These are some information that concerns phone systems Chicago.
