1. Cell Phones:
The mobile phone, otherwise known as the cell phone, uses a combination of voice and data to transmit. But basically, it uses a data network. When making a voice call, the voice is converted to data and when the phone connects to a cell tower for a voice call, the phone needs to send the data at a speed of 13 Kbps for outgoing audio and to receive data at that same speed.
Now, phones that support the fastest wireless broadband data networks, also known as 3G or more recently, 4G is best for Web surfing, streaming video or music or downloading data heavy attachments. This is due to packets of data being sent from one tower to the next.
2. Landline Phones:
Landline Phones uses voice networks. Land lines work by transmitting voice and data signals thru copper wire (and lately, by fiber optic cable using LED or Laser Technology) by use of electrical pulses.
POTS (Plain Old Telephone Service) is the voice grade telephone service that is based on analog signal transmission that was common before ISDN (Integrated Services Digital Network), cellular phones and VoIP (Voice over Internet Protocol)
As such, Landline phones would still work even if there’s a blackout or a satellite problem causing interference with mobile phones.
3. SMS/Text Messaging:
SMS (Short Messaging Service) is a text messaging service component of phone, web, or mobile communication systems. SMS uses data networks and is the most widely used data application available, with an estimated number around 3.5 billion active users or about 80% of all mobile phone subscribers at the end of 2010.
4. Fax Machine:
The traditional fax machine used the voice network. Many businesses still use the fax machine. The big reason is because it’s a good standby just in case the network does go down. There is IP faxing- a process for sending faxes over the Internet network. Internet faxing converts data packets of a fax transmission and sends these packets over the network as...
