Data Roaming vs Cellular Data Cellular data is the ability to use data services via cellular networks, whereas Data roaming is the ability to use such service while roaming outside the geographical coverage area of the service provider. Data roaming is dependent on the agreements between service providers and GRX (GPRS Roaming Exchange) hubs which […]
Difference Between Modulation and Demodulation
The key difference between modulation and demodulation is that modulation is to transfer the message signal by adding it with the carrier signal while demodulation is the process of filtering out the actual message signal from the carrier signal. In general, radio carrier generates at the transmission side of a telecommunication link. In transmission, it […]
Difference Between Diameter and SS7
Diameter vs SS7 Diameter and SS7 are signalling protocols generally used in telecommunication systems. Diameter is highly used in 3GPP latest releases for AAA services (Authentication, Authorization and Accounting), while SS7 was initially used with PSTN and GSM networks for digital signalling between different nodes for call management and other services management. Diameter protocol run […]
Difference Between RFID and NFC
RFID vs NFC Both RFID (Radio Frequency Identification) and NFC (Near Field Communication) technologies are identified as wireless technologies, which are used to transfer data within electronic devices. They are increasingly used in various kinds of applications in the real world to accomplish several tasks quicker and easier. RFID technology uses radio frequency waves to […]
Difference Between Wireless Broadband and Mobile Broadband
Wireless Broadband vs Mobile Broadband Wireless and mobile broadband provide fast methods to access the internet. In general broadband is a transmission facility that has the bandwidth to carry data, voice, and video channels at the same time. Different technologies are developed, in order to access the internet at bandwidths starting from few hundreds of kbps […]
Difference Between WCDMA and LTE
WCDMA vs LTE WCDMA (Wideband Code Division Multiple Access) and LTE (Long Term Evolution) are mobile communication technologies that falls under the 3rd Generation Partnership Project (3GPP) releases. LTE standards are part of the latest 3GPP releases, which are considered as 4th Generation (4G), and WCDMA is the older technology which was specified as 3rd […]
Difference Between CDMA and WCDMA
CDMA vs WCDMA Code Division Multiple Access (CDMA) and Wideband Code Division Multiple Access (WCDMA) are multiple access technologies used in telecommunication networks for users to access the network resources and services. Since the spectrum is a scarce resource, which is directly related to capacity, efficient use of the spectrum is a major concern in […]
Difference Between Encoding and Decoding
Encoding vs Decoding Encoding is the process of transforming data in to a different format using a method that is publicly available. The purpose of this transformation is to increase the usability of data especially in different systems. It is also used for reducing the storage space required to store data and for transferring data […]
Difference Between GSM and 3G Network Technology
GSM vs 3G Network Technology GSM (Global System for Mobile Communication) and 3G (3rd Generation mobile technology) are both mobile communication technologies that have been evolved over the time. GSM was introduced as a standard in 1989 while 3G was proposed by 3GPP (3rd Generation Partnership Project) in year 2000.GSM and 3G uses different multiple […]
Difference Between ATM and Frame Relay
ATM vs Frame Relay Data link layer of OSI model defines the ways of encapsulating data for transmission between two endpoints and the techniques of transferring the frames. Both Asynchronous Transfer Mode (ATM) and Frame relay are data link layer technologies and they have connection oriented protocols. Each technique has its own application dependent advantages […]
