Cellular communications

Events What is Cellular Communications: Mobile Technology Mobile phone or cellular technology is widely used and is based upon the concept of frequency re-use by the application on a series of coverage cells. What is cellular communications Mobile phone or cellular telecommunications technology has been in widespread use since the early s.

Branchless banking and Contactless payment In many countries, mobile phones are used to provide mobile banking services, which may include the ability to transfer cash payments by secure SMS text message.

Kenya's M-PESA mobile banking service, for example, allows customers of the mobile phone operator Safaricom to hold cash balances which are recorded on their SIM cards. Cash can be deposited or withdrawn from M-PESA accounts at Safaricom retail outlets located throughout the country and can be transferred electronically from person Cellular communications person and used to pay bills to companies.

Branchless banking has also been successful in South Africa and the Philippines. Zidisha uses mobile banking for loan disbursements and repayments, transferring funds from lenders in the United States to borrowers in rural Africa who have mobile phones and can use the Internet.

Eventually, the idea spread and in Cellular communications, the Philippines launched the country's first commercial mobile payments systems with mobile operators Globe and Smart.

Some mobile phones can make mobile payments via direct mobile billing schemes, or through contactless payments if the phone and the point of sale support near field communication NFC. Cellphone surveillance and Mobile phone tracking Mobile phones are commonly used to collect location data.

While the phone is turned on, the geographical location of a mobile phone can be determined easily whether it is being used or not using a technique known as multilateration to calculate the differences in time for a signal to travel from the mobile phone to each of several cell towers near the owner of the phone.

Both the SIM card and the handset can be tracked. They possess technology that enables them to activate the microphones in mobile phones remotely in order to listen to conversations which take place near the phone.

A sign in the U. It is widely considered dangerous due to distracted driving. Being distracted while operating a motor vehicle has been shown to increase the risk of accidents. In Marcha U. In Egypt, Israel, Japan, Portugal, and Singapore, both handheld and hands-free use of a mobile phone which uses a speakerphone is banned.

Cellular Communications Definition A cellular mobile communications system uses a large number of low-power wireless transmitters to create cells—the basic geographic service area of a wireless communications system. Variable power levels allow cells to be sized. A mobile phone, known as a cell phone in North America or hand phone in Asian English, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The fundamentals of radio propagation, modulation and cellular basics are also covered in a way that will give readers a real grasp of how cellular communications systems and equipment work. * Explains the principles and applications of cellular communications systems using a minimum of mathematics, providing a firm grounding for engineers /5(3).

In other countries, including the UK and France and in many U. A simulation study at the University of Utah found a sixfold increase in distraction-related accidents when texting.

This has introduced additional difficulties for law enforcement officials when attempting to distinguish one usage from another in drivers using their devices. This is more apparent in countries which ban both handheld and hands-free usage, rather than those which ban handheld use only, as officials cannot easily tell which function of the mobile phone is being used simply by looking at the driver.

This can lead to drivers being stopped for using their device illegally for a phone call when, in fact, they were using the device legally, for example, when using the phone's incorporated controls for car stereo, GPS or satnav.
