Devices to Send and Receive Messages

Abstract

Wireless communications, which include wireless messaging services, wireless internet

access points, and global positioning systems, are everywhere. Wireless instant

messaging is an Internet communications service that allows a wireless mobile device to

exchange instant messages with one or more mobile devices or online personal

computers. In many public locations, people connect to the Internet through wireless

Internet access points, the two types of which are hot spots and 3G networks. A global

positioning system (GPS) is a navigation system that consists of one or more earth based

receivers that accept and analyze signals sent by satellites in order to determine the

receiver’s geographic location. Anyone can take advantage of wireless communications

using mobile computers and devices.

Wireless Communications Using Mobile Computers and

Devices to Send and Receive Messages

Wireless communications are everywhere. People around the world regularly send

and receive messages wirelessly, that is transmitted through the air. Three types of

wireless communications include wireless messaging services, wireless Internet access

points and global positioning systems.

People use mobile phones, PDA’s and other mobile devices to access text

messaging, instant messaging, and picture messaging services. Through text messaging

Services, users send and receive short text message, which usually consist of fewer than

300 characters. Wireless instant messaging is an Internet communications service that

Allows a wireless mobile device to exchange instant messages with one or mobile

devices or online personal computers. Users send graphics, pictures, video clips, sound

clips, and short text messages with picture messaging services. Some messaging services

Use the term, video messaging, to refer separately to the capability of sending video

clips.

In many public locations, people connect to the Internet through a wireless

Internet access point using mobile computers and devices. Two types of wireless Internet

access points are hot spots and #G networks. A hot spot is a wireless network that allows

mobile users to check e-mail, browse the web, and access any internet service-as long as

their computers or devices have the appropriate wireless capability. A #G network,

which uses cellular radio technology, enables users to connect to the Internet through a

mobile phone or computer equipped with an appropriate PC card.

A global positioning system (GPS) is a navigation system that consists of one or

more earth based receivers that accept and analyze signals sent by satellites in order to

determine the receiver’s geographic location, according to Shelly and Cashman. A GPS

receiver is a handheld, mountable, or embedded device that contains an antenna, a radio

receiver, and a processor. Many mobile devices, such as mobile phones and PDA’s have

GPS capability built into the device.

Mobile users communicate wirelessly through wireless messaging services,

wireless Internet access points, and global positioning systems. Anyone can take

advantage of wireless communications using mobile computers and devices.
