LTE technology (Long Term Evolution) represents the fourth generation of mobile networks (4G) providing customers with a unique experience of using services which require high speeds of data trasfer, as well as faster access to applications such as video contents (Youtube, streaming, mobile TV, etc.), watching hig-quality video files (in HD format), music streaming, transfer and downloading of files, photos and other contets.
In Montenegro Telenor network population coveragewith 4G/LTE signal is around 45%.
GSM (Global System for Mobile communication)
is the technology which is worldwide most used for the requirements of mobile telephony. In the beginning, developed as the European standard for digital voice, data, and textual messages wireless transmission, GSM was also soon accepted by many countries outside Europe so that, today, according to the data of GSM Association (GSM Association, http://www.gsmworld.com
), it covers over 70 % of the world market of mobile communications.
Four frequency ranges are currently used for GSM mobile telephony:
900 MHz, GSM (Global System for Mobile communications)
1800 MHz, DCS (Digital Cellular System), also known as GSM1800
1900 MHz, PCS (Personal Communicatoins Systems), also known as GSM1900
GPRS (General Packet Radio Service)
GPRS is the protocol, which enables data transmission through GSM network. Before it was launched, the data, through GSM network, had been transmitted using CSD (Circuit Switched Data) and SMS (Short Message Service) protocols. Their limitations in rate and quantity (CSD 9600 bit/s and SMS 160 alphanumeric characters per message) called for the development of a new, better method of data transmission.
The theoretical maximum rate when using GPRS is 171.2 kbps. However, in practice, the transmission rate depends on several factors: the characteristics of the mobile telephone, signal level, distance of the mobile unit from the base station, etc.
EDGE (Enhanced Data rates for Global Evolution)
EDGE represents a step forward towards the third generation of (3G or UMTS) mobile communications. It represents faster data transmission via a mobile telephone within the existing GSM network, access to Internet, as well as to other networks based on Internet Protocol (IP). With EDGE, you get significant acceleration of access to all GPRS and MMS services.
The main advantages of EDGE are:
Higher rate of data transmission (EDGE: 236 kbps; GPRS: 53.6 kbps; GSM: 9.6 kbps);
Faster access to Internet and related services;
Faster sending and reception of MMS messages.
A key technology that we call third generation mobile telecommunications – 3G is UMTS, which is abbreviated of the Universal Mobile Telecommunications System.
Such technology enables its users to take advantage of a number of new services, such as video call, watching of TV programs, music spots and movies, ADSL, supervision over major roads and many other multimedia facilities.
HSDPA (High Speed Downlink Packet Acces)
HSDPA represents the natural evolution of third generation to what is becoming the need of nowadays> mobile and broadband access (mobile broadband). This technology is therefore often designated as 3.5 G, that is 3G+ and enables significantly higher speeds of flow with full mobility in coverage zone. Telenor from the very start enables its users to have transfer speeds up to 3.6 Mbps. Even now at several test locations in Podgorica, our users can experience speeds of flow up to 7.2 Mbps. Redirecting to 2G signal devices do automatically (without stopping the service) in zones where there is no 3G+ coverage.
WiMAX (Worldwide Interoperability for Microwave Access)
WiMAX is the abbreviation of English compound Worldwide Interoperability for Microwave Access, and stands for a name for broadband wireless telecommunication technology (IEEE 802.16) which supports fixed, transferable and mobile access.
WiMAX technology enables broadband wireless access in the last part (English term “ last mile” is often used) as the alternative to wire broadband access to cable and DSL systems. The key advantage of WiMAX technology is more efficient usage of frequency volume and higher speeds of data transfer (from 1 megabit per second to theoretical 109 megabits per second), large scope and mobility.
Portable computers and PDA devices that will support WiMAX technology will turn urban zones and towns into “metro zones” for mobile broadband wireless access.
WiFi (Wireless Fidelity)
WiFi or Wireless Fidelity represents wireless telecommunication technology (IEEE 802.11) that enables reliable and fast transfer of data from the access point to the computer or other device.
WiFi technology operates within the spectrum of 2.4 and 5 GHz, with speed of transferring data of 11 megabits per second up to 54 megabits per second (theoretically even more), but different from WiMAX it is characterized by substantially smaller range (of 100 matars). Almost all of the modern electronic and telecommunication devices posess support for this technology.
At some locations (especially in hotels, marines, stores, tourist zones and similar) WiMAX network is used as transport asset for the set of WiFi access points.
We have decided to combine WiMAX, HSPA and WiFi technology in order to enable our users to have larger accessibility to the service.
