544 Mbs. The ISDN is accessed over one or two services, named by the CCITT as the Basic Rate Access (BRA) and Primary Rate Access (PRA). The speed range of the broadband service is upto 25 Mbps up to the gigabit range. Frame Relay Frame relay creates a long-lasting virtual circuit or a switched virtual can support a various user over the same line. Frame relay is a simple form of a packet switch as it expands up to X. 25 packet switch which help to reduce the network delay, protocol overheads, and the equipment cost. In the X. 25 switching the error correction is done on end-to-end basis instead of using link to link basis. It is the simplest form of packet switching which offer a high speed of transmission and it is generally used to give direction to the protocols such as IPX or TCP/IP and to carry asynchronous traffic or other voice data. There is not any security of data integrity but the Frame relay switches packets end to end are faster. Characteristics of Frame Relay are:- Frame relay is flexible in length and it is up to 4, 096 bytes.

What is Low Power Wide Area Network (LPWAN) Technology? Low Power Wide Area ( LPWA) technology emerged as a term in 2013 not as a new technology standard, but rather as a class of wireless technologies that are well suited to the specific needs of machine-to-machine (M2M) and IoT devices. The majority of IoT devices, especially those in smart city and industrial sectors, don't require the same speed and bandwidth of consumer cellular devices. However, they do need the longevity of traditional LTE cellular networks. LPWA technology gained prominence as the preferred choice for IoT applications in 2015 when the GSMA wireless industry association defined a series of LPWA Network (LPWAN) standards to help network operators meet the specific cost, coverage and power consumption needs of IoT applications. These standards included LTE-M and NB-IoT. Simultaneously, the LoRa Alliance was formed to strengthen another emerging LPWAN technology adding another wireless connectivity option for low bandwidth, low latency IoT applications.

> Network Diagram > Wide Area Network Technologies - Design and Implement High-quality WAN Networks Edraw Network Diagram is ideal for network engineers and network designers who need to draw wide area network diagrams. Wide Area Network Technologies A Wide Area Network (WAN) is a computer network covering multiple distance areas, which may spread across the entire world. WANs often connect multiple smaller networks, such as local area networks (LANs) or metro area networks (MANs). The world's most popular WAN is the Internet. Some segments of the Internet are also WANs in themselves. The key difference between WAN and LAN technologies is scalability. C WAN must be able to grow as needed to cover multiple cities, even countries, and continents. A set of switches and routers are interconnected to form a Wide Area Network. The switches can be connected in different topologies, such as full mesh and half mesh. A wide area network may be privately owned or rented from a service provider, but the term usually connotes the inclusion of public (shared user) networks.
WAN technologies generally function at the lower three layers of the OSI reference model: the physical layer, the data link layer, and the network layer. Key technologies often found in WANs include SONET, Frame Relay, X. 25, ATM and PPP. ATM: A dedicated-connection switching technology that organizes digital data into 53-byte cell units. Individually, a cell is processed asynchronously relative to other related cells and is queued before being multiplexed over the transmission path. Speeds on ATM networks can reach 10 Gbps. Frame Relay: (FR). A high-speed packet-switched data communications service, similar to X. 25. Frame relay is widely used for LAN-to-LAN interconnect services, and is well suited to the bursty demands of LAN environments. SONET/SDH: Synchronous Optical Network is an international standard for high speed communication over fiber-optic networks. The SONET establishes Optical Carrier (OC) levels from 51. 8 Mbps to 10 Gbps (OC-192) or even higher. Synchronous Digital Hierarchy (SDH) is a European equivalent of SONET.
