...Cell phones are both voice and data. Voice was the first initiative use for the phone. Then after they have noticed that the cell phone could transfer data, they decided to push the data limitations. That is how we got to 4g today. A landline is voice without a modem. The landline cannot transfer data unless it has a converter called a modem. When this modem is applied the landline then could connect to a computer and transfer data. Sms/text messaging is definitely just data. There is no voice involved in those programs. Texting is the same as typing and is delivered like a message from an email. Sms is correlated with chat online which is a data transfer. Fax machines are considered voice/data. With this I do get confused. On some fax machines you talk on them, while others are more like computers. Most fax machines are connected to the landline. Pagers are data, there is not talking into them. And you can only receive data, and maybe send one back. Some pagers are considered sms/text messengers, with that in mine; it definitely reassures me that it is a data. VoIP is data. You ask me how I know. I say because of the cord that it has to go through. It would most likely go through a cat 5. VoIP is an online phone service. Anything online is considered data regardless of the voice that you get to input into it. Skype and face time are both voice and data. It really depends I guess where you Skype from or with what. Cell phones are both data and voice. So what is Skype…...

...carriers use data networks. Some of the most common technologies used are HSDPA, HSUPA, EDGE, HSPA and UMTS. These are all 3G technologies and provide some of the fastest 3G speeds. 2. Landlines also use data networks. Once the sounds leave your home or business on the telephone lines it will go to the Telco’s switch in the area or to a digital concentrator box. Here your voice is digitized into 8,000 samples per second and 8-bit resolution before being transmitted onto its destination. 3. SMS/Text Messaging uses data networks also. This would seem natural since most cell phones use data networks and SMS/Text Messages are sent from cell phones. The way it works is because cell phones are always sending and receiving information, even when they are not in use. This is so the phone is constantly telling towers where it is so when a message is sent to a particular number the message can find its intended recipient. 4. Not surprisingly, Fax Machines use a data network to send information. This is done by digitizing an image. I say image because even if it is a text document it is still taking a picture of the document and transmitting it to the recipient. It is divided into a grid of dots and each dot would either be “on” or “off” using a 1 or 0. 5. Pagers use a data network also. Pagers are used to send messages and are sent from either a phone line or through email. There is not the option to send any type of document and/or voice communication and therefore a voice network would...

...Cell Phones: When cellular phones first came about they were all voice transmitting information in an analog format, similar to a fixed-line telephone. (Andrew Oliviero, 2012) Once the second generation of cell phones was introduced in the late 90s early millennium the transmission shifted from analog to digital. Aside from using voice, they introduced data which allows you to text or send an MSM to another person without actually talking. Think of using AOL or MSN messenger back in the day on your computer except through your cell phone. Now we are up to 4G which allows more data, applications, and a stronger connection. A minicomputer in your pocket that allows you to talk, text, play games, email, GPS, varies applications such as counting your calorie intake for you. Fax Machine: Fax machines use voice to transfer data. The fax would be connected to a Voice over IP line if it could, but that specific data transfer was not designed to carry fax, therefor fax over VoIP is not reliable. You would lose data packets because UDP would simply ignore it, and VoIP uses UDP packets to send voice data to the phone line. Pagers: In the beginning pagers only used the data networks sending just numbers from the control system to the devices. Then over time the pagers systems changed by using both voice and data network with sending voice messages to the pagers. Each station covers a wide area range from 15 to 30 miles. The page is transmitted over RF by the transmitter. Different...

...Voice vs. Data In this lesson we talked about seven things to compare the difference between voice and data communication. The first item are cell phones, cell phones are voice and data communications. Cell phones are a mobile device used for voice and data communication over a network of base stations, sites where antennas and electronic communication equipment together create a cell in a mobile phone network. Today mobile phones are used for many other purposes than the standard voice function, which is it primary purposes. Mobile phones are used for text messaging by means of SMS, for sending and receiving videos and photographs by means of MMS and for email and internet services using GPRS. The second was Landline phones, Landline phones are voice communication. Landline telephones serve a variety of functions, even in today’s largely mobile world. Accessibility of landline phones for people with disabilities means that the range of services provided through landline phones to everyone without disabilities is also accessible in some ways that provides equivalent functionality for people with disabilities. There are several accessibility features which are either present in a telephone, or can be added by attachment; these included speakerphone functionality, large keys, flash on incoming calls, ability to connect a Braille reader. Landline phones are also used for very limited data collection, data retrieval and remote control through the digit transmission they...

...in a given area. It use both voice and data network. 2. A landline telephone is a device with a physical line connection to a telecommunications network. The phone is plugged into a phone jack in the wall in order to connect with the larger system of cables and relays controlled by the telephone company. These phones use voice network. 3. SMS (short message service) is text messaging. The maximum size of one text is 160 characters. The phone is constantly sending and receiving information. It is talking to its cell phone tower over a pathway called a control channel. The reason for this chatter is so that the cell phone system knows which cell your phone is in, and so that your phone can change cells as you move around. The tower sends the message to your phone as a little packet of data on the control channel. 4. A document is scanned with a fax machine which processes the contents as a single fixed graphic image, converting it into a bitmap and then transmitting it through the voice network. 5. The paging service takes the message and sends it onto the paging centre. The paging centre transmits the message via radio signal (data network) to the base stations and transmitters. 6. VOIP is a method for taking analog audio signal, and turning them into digital data that can be transmitted over the Internet. 7. Skype is software that enables users to make video and voice calls with other Skype users and non-users. It relies on voice-over-Internet protocol, VoIP...

First Generation (1G) phones were known for their voice data. However, when Second Generation (2G) phone were created, they were about to transmit and receive via voice and data networks. Third Generation (3G) and Forth Generation (4G) both transmit and receive via voice and data networks as well. In fact, cell phones are commonly used to transmit via data networks due to people preferring to text/email rather than placing voice calls to one another. • Landline phone use both data and voice networks. Landlines work by transmitting voice and data signals by copper wire through electric pulses. This means landline phones would still work even if there was a blackout or a satellite disturbance, causing interference with mobile phones. • SMS / Text Messaging use data network.

...Voice and Data Communication Elisha Myles NTC/360 February 21, 2011 In many households can have various setups of a network from basic Internet connections to electronic devices. Here we will explain how one home network system can be achieved with the proper hardware and devices to make it work. In this home network consist of one desktop computer hard wired with Arris Telephone Telephony cable modem and CATV coaxial cable wiring provided by the cable company. The computer is connected to the cable modem through Ethernet connection and also has a telephone line connection. This is also connected using Ethernet wiring to a NETGEAR Wireless N Router (WNR2000) with a Push ‘N’ Connect feature for using WiFi protection that comes in handy because the house also has a laptop that uses a Wireless-N 300 USB adapter and Playstation 3 in a separate room, both are protected by a password, this is important because the wireless will pick up other signals in the neighborhood and it provides security from other people gaining access to the computer. The differences between Rotary and Dual Tone Multi-frequency phones are with rotary phones or the rotary dial was improvements to the old form of sending telegraph signals in the 1900s. The rotary dial phones was a mounted device on a telephone or switchboard designed to send electrical pulses that corresponded with the number dialed.

...Phones – The first generation of cell phones transmitted voice through an analog wireless connection. The current generations of phones use both voice and data sent over digital wireless connections to transmit their signals. A cell phone is used for full duplex two-way radio telecommunications (for both voice and data) over a cellular of stations known as cell sites. Landline Phones – Landline phones use analog voice. They are connected to the Central office by a local loop that is 2 copper wires in a twisted pair. Landline phones get their power from this local loop. Also call POTS nowadays or Plain Old Telephone Service. SMS/Text Messaging – SMS stands for Short Message Service. The control channel (a pathway from your cell phone to the cell tower) provides the pathway for SMS messages. When you send an SMS message, the message flows through the SMSC, then to the tower, and the tower sends the message to the phone as a little packet of data on the control channel. Fax Machines – Fax Machines connect to another device on the other end of the line. They convert the images to data and transmit them over the analog telephone lines. If the spot of paper that the photo cell was looking at were white, the fax machine would send one tone; if it were black, it would send a different tone. Pagers – pagers work on radio waves similar to cell phones. When someone calls a pager and inputs a number it gets sent to the pager via a data packet. A pager is primarily used in hospitals, any office...

...September 17, 2015 Voice vs. Data Cell phones- wireless phones served by a cellular telephone system broken into small geographical areas. It’s a two-way that carries full duplex conversations. Cell phones have evolve from 1G, which carries information similar to the way fixed line phones transmit voice from subscriber to central office to 4G network for fast access of the internet. It uses both voice and data networks. (woodward, 2012) Landline phones – Initially landline phones started as a device to transmit voice. While it didn’t seem like a good choice to transmit data, however, for many years it was subscribers’ only choice for transmitting data. SMS/Text messaging –The short messaging services (SMS) still works on voice networks. It is the mechanism of sending short messages over mobile networks. The message from the sending mobile is stored in a central SMS center which then forwards it to the destination. SMS can be no longer than 160 characters. (http://www.wirelessdevnet.com) Fax Machine – short for facsimile machine is a device that can send or receive pictures or text over a telephone line. It works by digitizing the image into grids of dots. The dot is either black or white representing on or off. (http://www.webopedia/TERM/fax-machine.html) VOIP (voice over IP) uses VOIP technologies for placing and transmitting calls over an IP network such as the internet, instead of the traditional public switch telephone network (PSTN).

...phones I would say uses both data and voice. You can use these devices to talk to other people via voice, and you can use it to access the internet via data services. Cell towers are essential for either of these functions to work. • Landline Phones - Landline phones originally were voice only. Created to carry audio from human beings. With the invention of modems, and then to IDNS and now DSL, it is also used as data as well. • SMS / Text Messaging – SMS / Text messaging uses Data services. These services allow you to send and receive blocks of characters (ie letters / numbers) between devices. There are no vocal communication done between these devices. • Fax Machines – Fax Machines use data services. It takes a digital print of a document and turns them into packets of data to be sent to a receiving fax machine that then takes those packets of data and translates them into a printed document. • Pagers – A pager is a device that uses data services. It would take an incoming call by its tone and transfer that data into a readable digital message. This way the receiving person can then use that message to call back a person at the given number on the device. • VOIP (voice over IP) Phones – VOIP like Vonage uses Data services. One might think that voice services would be used seeing you are making a call, but it’s all done on a digital level. It takes your voice, transforms it into data that is then sent out and transformed back into voice at the receiving end. It...

...Assignment 1. Voice vs. Data Cell phones use both voice and data networks. Both of these networks can use the same antenna. Cellular networks allow automatic and persuasive use of mobile phones for voice and data communication even though you usely use a cell phone to talk on it, the new cell phone killer app is data. Landlines phones use both voice and data networks. They work by transmitting voice and data signals by copper wire. Landlines refer to a phone that uses a solid medium telephone line such as a metal wire or fiber optic cable for transmission. In 2003 there was 1.263 billion main telephone lines worldwide. SMS/Text messaging known as short messages use a data network. SMS is a service component of phone, web, or mobile communication systems. It uses standardized communication protocols to allow fixed line or mobile phone devices to exchange messages using data application. Has an estimated 3.5 billion active users. Fax Machines use voice networks. With a fax line you plug into a fax terminal adapter, and then plugs into a network connection. They often share a phone extension and have a fax switch. You need to use a proper fax over IP protocol, such as T.38 to achieve consistent reliable faxing. Pagers are designed to receive the paging signals that are transmitted under control of the paging terminal. These paging signals are designed to carry pager-specific address information in order to alert an individual pager. Pagers use voice and data networks. VOIP...
