Glossary
2,5 G :
2,5G is a non-official term that covers GPRS technology between the second (2G) and third (3G) generations of mobile telephony. GPRS is an extension of GSM standard providing higher data transfert rate and can be utilized for services such as WAP access, SMS / MMS and emails.
3G+ :
3G+ is a commercial naming that designates HSDPA, an evolutionary improvement for the UMTS standard. HSDPA achieves the increase in the data transfer speeds up to 10 times higher than 3G (UMTS) technology.
ADSL :
Asymmetric Digital Subscriber Line (ADSL) is a data communications technology that enables faster data transmission, voice over IP and TV-cast over copper telephone lines.
ARPU :
Average revenue per user (ARPU) is used by (fixed-lined or mobile) operators to calculate the revenue generated by a customer per month. ARPU includes not only the revenues billed to the customer each month for usage, but also the revenue generated from incoming calls, payable within the regulatory interconnection regime. ARPU reached 32,5 EUR in 2005 by European mobile operators (vs 65 EUR in Japan)
CRM :
Customer Relationship Management (CRM) is a broad term that covers concepts used by companies to manage their relationships with customers, including the capture, storage and analysis of customer information.
Dégroupage :
See Local Loop Unbundling.
DRM :
Digital Right Management (DRM) refers to technologies used by publishers or copyright owners to control access to and usage of digital data or hardware, and to restrictions associated with a specific instance of a digital work or device.
DVB-H :
DVB-H (Digital Video Broadcasting - Handheld) is a technical specification for bringing broadcast services to handheld receivers. This technology adapts the successful DVB-T (Digital Video Broadcasting - Terrestrial) system for digital terrestrial television to the specific requirements of handheld, battery-powered receivers
EDGE :
Enhanced Data Rates (EDGE) is an evolution of the GSM mobile network technology technology. It is generally classified as a 2.75G network technology. It allows to increase data transmission rate and improve data transmission reliability.
Fibre Optique :
Developed in the 70's, the Optic Fiber offers possibilities to transport a big amount of data in high speed mode (compared to coax cables for example). Makes it possible to use content services as visio conferences, television, phone and transport large packages of data.
FTTH :
Fiber To The Home (FTTH) is a form of fiber optic communication delivery in which the optical signal reaches the end user's living or office space. This still expensive technology will compete with xDSL / Cable on dense area offering much higher data transfer rates (1 Gbit/s) and reliability.
HSDPA :
High Speed Downlink Packet Access (HSDPA) is an evolutionary improvement for the UMTS standard. HSDPA achieves the increase in the data transfer speeds up to 10 times higher than 3G (UMTS) technology.
Local Loop Unbundling :
Local loop unbundling (LLU) is the regulatory process of allowing multiple locally- and national-based telecommunications operators to make use of connections from the telephone exchange's central office to the customer's premises.
MBMS :
Multimedia Broadcast Multicast Service (MBMS) is a broadcasting service that can be offered via existing GSM and UMTS cellular networks. The infrastructure offers an option to use an uplink channel for interaction between the service and the user.
MVNO :
A mobile virtual network operator (MVNO) is a company that does not own a licensed frequency spectrum, but resells wireless services under their own brand name, using the network of another mobile phone operator.
TV HD :
High-Definition Television (HDTV) covers both technologies and equipments that allows high quality TV broadcast. It is enabled by 2 technologies evolutions: emerging digital broadcast and increasing size and resolution of screens.
UGC :
User-generated content (UGC) refers to various kinds of media content that is produced or primarily influenced by end-users. The term came into the mainstream during 2005 in web publishing and new media content production circles.
UMTS :
Universal Mobile Telecommunications System (UMTS) is one of the 3rd generation mobile technologies. It supports up to 1,920 Mbit/s data transfer rates in theory although at the moment users in deployed networks can expect a performance up to 384 kbit/s. Nonetheless UMTS enables downloading of music and video content, as well as live TV or Video telephony.
VOD :
Video on Demand (VoD) covers the distribution of video content available for download to end-users through high-bandwidth fixed-line (ex. : ADSL) or wireless network (ex. : 3G).
VOIP :
Voice over Internet Protocol, (VoIP) is the routing of voice conversations over the Internet or through any other IP-based network.
