What is Global Area Network:Global Area Network is a network composed of several interconnected networks covering an unlimited geographical area. The term is synonymous with the Internet, which is called Global Area Network. Explanation: Compared with Local Area Network (LAN) and Wide Area Network (WAN), Global Area Network covers a large geographical area, because a Global Area Network (GAN) is used to support mobile communication over a series of wireless LANs , the challenge of any GAN is to transfer user communication from one local area to the next local area. The most widely used network after the GAN type is the broadband GAN. Broadband GAN is a global satellite internetwork that uses portable terminals for telecommunications. The terminals will be connected to computers and laptops in remote areas to broadband Internet. Global Broadband Network (BGAN): BGAN is a global satellite internet that can use portable terminals for telecommunications. Terminals used to connect computers and laptops to broadband Internet in remote areas, even if there is line of sight to the satellite, can be used anywhere. The value of BGAN terminals is that, unlike other satellite Internet services, which require huge and heavy satellite dishes to connect, a BGAN terminal is the size of a computer or laptop and can be transported easily. The network is provided by Inmarsat and uses 3 geostationary satellites to provide near-global coverage. What is INMARSAT: It is a leading global satellite services company and its services allow users to make telephone calls, video calls and access the Internet. Operation: High- BGAN terminals with upload and downlink speeds of up to 492 Kbit/sec,...... half the paper......capacity: BGAN delivers mobile broadband connectivity to the office whenever and wherever is required. BGAN supports modern IP services, as well as ISDN data and PSTN services. Advantages:  It is an interconnection of networks covering a geographical area Various applications: It is mostly used for sending emails, voice calls, web browsing, SMS, etc. . Designed for all industries: such as mining, oil/gas services and even engineers. Performance: Supports ISDN at 64 kbps and offers high data transmission speed.
