The Communications sector includes technologies that are targeted at the private and public telecommunications markets. It may be easier to define as what it does NOT include, such as Internet technologies, communications-related semiconductors and new media – all to be found under different sectors in the database. The technologies that ARE included are mainly related to communications infrastructures on the one hand and specific applications and devices on the other.
FTTx, xDSL, CATV, IPTV, MPEG, Router, Switch, Cable, LAN, WAN, WLAN, Wi-Fi, 802.11, 802.16, DSL, SOHO, WiFi, WiMax, LTE, OFDM, Ethernet, Radio, TV, Telecom, Telco, WLAN, GSM, TDMA, CDMA, VAS, Antenna, Wireless, Cellular, PDA, Operator, Modem, IP, RF, Telephony, Phone, Television, Carrier, ITU, SIP, Protocol, GPS, SDH, SONET, Fiber, PON.
An access network is that part of a communications network which connects subscribers, mostly homes and businesses, to their immediate service provider (also referred to as The Last Mile). It is contrasted with the core network, which is the central part of the telecom network. Relevant technologies which enable the access network a wider bandwidth are: xDSL, FTTx (Fiber-To-The-X), PON (Passive Optical Network), BWA (Broadband Wireless Access).
Dedicated to Television, Video and Audio Broadcasting Technologies. Amongst them are CATV (Cable TV - a system of providing television to consumers via RF signals transmitted to televisions through fixed optical fibers or coaxial cables), IPTV (Internet Protocol Television - a system where a digital television service is delivered using Internet Protocol), ITV (Internet television - a television distributed through the Internet). Other relevant keywords: HDTV, VOD, Video and Audio Compression (MPEG), streaming and various satellite technologies.
An enterprise network connects all the isolated departmental or workgroup networks into an intra-company network, with the potential for allowing all computer users in a company to access any data or computing resource. It provides interoperability among autonomous and heterogeneous systems, integration and management of disparate networks. The enterprise network has the eventual goal of reducing the number of communication protocols in use. Common technologies: LAN, WLAN, VPN, Ethernet.
Home network is defined as two or more computers interconnected to form a local area network (LAN) within the home (wired or wireless). It allows computer owners to interconnect multiple computers so that each can share files, programs, printers, other peripheral devices, and Internet access with other computers, reducing the need for redundant equipment. The advanced home network provides home automation, i.e. controls for the home ambient environment, security systems, household appliances etc. This sub-sector also includes SOHO (Small Office/Home Office) Networks.
Refers mostly to applications which are developed for Mobile phones and smartphones. Companies in this sub-sector engage mostly in the development of applications related to one or more of the following: Entertainment, Gaming, Advertisement, M-Commerce, LBS, Mobile web. Applications developed by companies in this sub-sector often use software technologies such as Symbian, BREW, Java, J2ME, and Linux.
Includes companies which develop components (such as antennas, base stations, amplifiers etc.) and technologies which conduct the cellular network infrastructure. Furthermore, it contains companies which develop innovative mobile handsets. Relevant keywords: GSM, CDMA, Wimax, LTE, OFDM, 3G, 4G, HSPA.
NGN & Convergence
Next-Generation Network (NGN) is the term given to describe a telecommunications packet-based network that handles multiple types of traffic (such as voice, data and multimedia). It is the convergence of service provider networks that includes the public switched telephone network (PSTN), the data network (the Internet), and, in some instances, the wireless network as well. This sub-sector also includes Fixed-Mobile Convergence (FMC) – the ability to provide fixed and mobile services with a single phone or personal device, which could switch between networks ad hoc.
Dedicated to networking technologies that rely on optical transmission of digital data as light pulses using fiber optic communications. Optical networks are high-capacity telecommunications networks based on optical technologies and components that provide routing, grooming, and restoration at the wavelength level as well as wavelength-based services.
Companies included in this sub-sector engage in the development of technologies such as lasers, WDM (Wavelength Division Multiplexing), SDH/SONET (Synchronous Digital Hierarchy/Synchronous optical networking) and products such as fiber-optic cables, amplifiers and optical switches.
Please note that technologies such as PON and FTTx can be founded under the "Broadband Access" sub-sector.
Telecom applications refer mostly to software either embedded into a system or separately installed on a main computer, for the control, diagnostics and performance analyses of all telecom (mainly networking) hardware. The relevant applications provide different services, such as Network or traffic Management and Optimization, QoS (Quality of Service). OSS/BSS (Operations Support Systems / Business Support Systems), Billing, Roaming, CRM (Customer Relationship Management) and other Value Added Services (VAS). Main users of telecom applications are ISPs (Internet Service Providers), telecom carriers and service providers.
VoIP & IP Telephony
VoIP (Voice over Internet Protocol) is a general term for a family of transmission technologies for delivery of voice communications over the Internet or other packet-switched networks. IP telephony describes telephony devices that use IP as the native transport for voice and call signalling. VoIP & IP Telephony are important for Computer telephony integration (CTI), a technology that allows interactions on a telephone and a computer to be integrated or coordinated. Other technological keywords might be H.323 - a set of standards from the ITU-T, which defines a set of protocols to provide audio and visual communication over an IP network, and SIP (Session Initiation Protocol).
Applications developed for wireless networks or PDAs (Personal Digital Assistant). Common usages of these applications are: business - rugged PDAs (EDA - Enterprise Digital Assistants) used for Mobile Workforce and Fleet Management; supply chain management or facilities maintenance and management such as remote monitoring and Telemetry. RFID (Radio-Frequency Identification) applications, Navigation and LBS (Location Based Services) combining GPS. Other relevant wireless technologies are Wi-Fi and Wlan (802.11).
Refers to telecommunications networks where interconnections between nodes are implemented without the use of wires. Relevant technologies include WLAN, Wi-Fi, WiMAX (802.16), RF, Microwave and Bluetooth. This subsector includes defense and military wireless networks and equipment as well.
