Mobile IP or MIP is an Internet Engineering Task Force (IETF) RFC 2002, De-Facto standard communication protocol. It is created by extending Internet Protocol, IP. The Mobile IP allows mobile device users to move from one network to another while maintaining the same permanent IP address. The concept and role of Mobile IP are very…

Wireless Application Protocol or WAP is a programming model or an application environment and set of communication protocols based on the concept of the World Wide Web (WWW), and its hierarchical design is very much similar to TCP/IP protocol stack design. See the most prominent features of Wireless Application Protocol or WAP in Mobile Computing: WAP…

Bluetooth technology is a high speed and low powered wireless technology designed to connect phones or other portable equipment for communication or file transmissions. This is based on mobile computing technology. Following is a list of some prominent features of Bluetooth technology: Bluetooth is also known as IEEE 802.15 standard or specification that uses low…

Spread spectrum is a technique used for wireless communications in telecommunication and radio communication. In this technique, the frequency of the transmitted signal, i.e., an electrical signal, electromagnetic signal, or acoustic signal, is deliberately varied and generates a much greater bandwidth than the signal would have if its frequency were not varied. In other words,…

Minimum Shift Key Modulation is another type of digital modulation technique used to convert a digital signal into analog signals. It is also called Minimum-shift keying (MSK) or Advance Frequency Shift Keying because it is a type of continuous-phase frequency-shift keying. Key features of Minimum Shift Key Modulation or Minimum-shift keying (MSK) Minimum-shift keying or MSK was…

Modulation is a process of mixing signals with a sinusoid to produce a new form of signals. The newly produced signal has certain benefits over an un-modulated signal. Mixing of low-frequency signal with a high-frequency carrier signal is called Modulation. In other words, you can say that “Modulation is the process of converting one form of…

Multiplexing is a technique used in the area of electronics and signal processing. In mobile computing, telecommunications and computer networks, Multiplexing is a method that can be used to combine multiple analog or digital signals into one signal over a shared medium. The main aim of using this method is to share a scarce resource.…

Fixed and Wireless Networks are both used in Mobile computing. Fixed networks commonly operate on radio transmission to connect established, wired communications systems. Let’s see the differences between fixed and wireless networks in mobile computing. Difference between Fixed and Wireless Networks The differences between Fixed and Wireless networks can be distinguished as that the wireless…

The main idea of Mobile computing was evolving since the 1990s. It has evolved from two-way radios to modern day communication devices. Devices used in Mobile Computing Following is the list of most common forms of devices used in mobile computing: 1. Portable Computers A portable computer is a computer that is designed in a…
