NOKIA PREPARES OOREDOO TUNISIA FOR 5G WITH CLOUD MOBILE CORE PROJECT

Tunisia power distribution box project

Tunisia power distribution box project

The project comprises five (5) main components: (i) construction of new infrastructure; (ii) rehabilitation of the MT networks; (iii) rehabilitation of the LT networks; (iv) procurement of equipment and resources for studies and operations, and (v) engineering designs, works. TUNIS, November 11, 2025 — The World Bank and the Government of Tunisia have concluded a financing agreement to support Tunisia's energy sector modernization agenda through the Tunisia Energy Reliability, Efficiency, and Governance Improvement Program (TEREG). Tunisia has a current power production capacity of 5,944 MW installed in 25 power plants, which produced 19,395 gigawatt hours in 2024. Revised in November 2024, this map provides a detailed view of the energy sector in Tunisia. The locations of power generation facilities that are operating, under construction or planned are shown by type – including gas and liquid fuels, natural gas, hybrid, hydroelectricity, solar (PV and CSP). The proposed project aims at strengthening Tunisia's electricity transmission system and improving power and gas distribution systems. In 2014, STEG operates a 6 209 km of transmission network distributed as follows : In addition to their function to meet a perpetual growing demand, the new works will allow us to minimize the risks of obsolescence and to prepare our network to play its role as a link in a large system.

Mobile Communication Core Network Switch

Mobile Communication Core Network Switch

Switching is the foundational component of the Core Mobile Network, responsible for routing and relaying communication between different network nodes. Cellular mobile communication is a radio-based system that provides mobile services by dividing a coverage area into multiple small coverage zones called cells. Users connect via mobile terminal devices, such as a mobile phone, to transmit and. As a result, two nodes, SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node) became part of the 2G core network. It's the part of the network where decisions are made, subscribers are authenticated, services are delivered.

What are the core architecture switches

What are the core architecture switches

Sitting at the top of the hierarchical model, core switches interconnect distribution layer switches and provide high-speed data transfer across network segments. Unlike access or distribution switches, a core switch is optimized for Layer 3 performance, modular scalability, and. This determines network efficacy, dependability, and the speed at which information is exchanged. A core switch is the backbone of a large-scale network, designed to handle massive volumes of traffic with ultra-low latency and maximum reliability.

Nicaragua Large Core Fiber OM4

Nicaragua Large Core Fiber OM4

OM4 was developed specifically for VSCEL laser transmission and allows 10 Gig/s link distances of up to 550m compared to 300M with OM3. To recap Optical Fiber can be divided into Multimode Fiber (MMF) and Single-Mode optical fiber (SMF). Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at. 5/125µm and 50/125µm, which are much larger than the 9/125µm core of. There are five main types of multimode fiber, standardized by ISO/IEC 11801: OM1, OM2, OM3, OM4 and OM5. WideBand OM5 Multimode Fiber is a 50 micron (μm) laser-optimized multimode fiber designed to help meet the demanding requirements of today's 850 nm based networks, as well as next-generation multimode short wavelength division multiplexing (SWDM) applications.

Core switch has two VLANs

Core switch has two VLANs

This post will deal with creating Layer 2 VLANs on Cisco switches and performing all relevant configurations. By default, only VLAN 1 is configured on the switch, so if you connect hosts on an out-of-the-box switch they all belong to. Configuring a switch to support multiple VLANs isolates network traffic, improving security and performance.
