The third generation (3G) cellular systems were developed with the purpose of offering high speed files and multimedia connectivity in order to subscribers. The International Telecommunication Union (ITU) provides standard known as, IMT-2000 (International Mobile Tele commmunications-2000 for 3G systems or devices. This lecture also briefly explain Core Network (CN). The Core Network is divided in circuit switched and packet switched domains.
This lecture briefly describe on Wireless LAN Network Communication System. A Wireless LAN provides wireless network communication over short distances using radio or infrared signals instead of traditional network cabling. Each user in the wireless network communicates directly with all others, without a backbone network sometimes called ad-hoc network. Here also briefly explain Infrared LANs, Narrowband RF LANs, Spread Spectrum LANs etc. Finally explain Wireless LAN requirements.
Principle purpose of this lecture is to explain Mobile and Wireless Communication System. Wireless communication is one of the fastest-growing technologies. The demand for connecting devices without the use of cables is increasing everywhere. Wireless LAN technologies can be classified into four types: infrared, spread-spectrum, narrowband RF and home RF and Bluetooth. This lecture briefly explain benefits of Wireless LANs and major problems with wireless network.
A Wireless LAN provides wireless network communication over short distances making use of radio or infrared signals as an alternative to traditional network cabling. Wireless communication is the fastest-growing technologies. The demand for connecting devices without the application of cables is increasing everywhere. major principle of this lecture is to explain on Wireless LAN Technologies. This lecture briefly describe on the benefits of Wireless LANs and find out major problems with Wireless network.
Wireless mobile ad-hoc network technology is designed for the establishment of a network anywhere and at any time, without any fixed infrastructure to aid the mobility of the users inside network. A wireless ad-hoc network is an accumulation of mobile nodes with a dynamic network infrastructure developing a temporary network. This lecture briefly describe on the overview of Wireless Ad-Hoc Networks and Routing in Ad-Hoc Networks.
This lecture briefly explain technical evolution of 3G System. The third generation (3G) cellular networks were developed with the plan of present high speed data and multimedia connectivity to subscribers. The International Telecommunication Union (ITU) provides the standard known as, IMT-2000 (International Mobile Tele commmunications-2000 for 3G system. Here brielt explain on UMTS System Architecture, UMTS Network Architecture and CDMA2000 evolution to 3G.
This lecture briefly describe on fundamental of Networking and Internetworking. Networking is any connection between two or more computers. A network’s speed can be summed up with two values: Bit rate and Latency. Internetworking is any connection between two or more networks. Here also explain what is Local Area Network (LAN), Important Network Properties, Internet Implementation. here focus on various Schemes for Organizing the Responsibility of Networking Components. Finally explain some Network Service Models.
This lecture briefly describe on how to Deal with different types of networks. Here major focus on Circuit-switched (e.g. telephone) and Packet-switched (e.g. Ethernet, ATM) networks. This lecture also focus on Multiple Access Strategies; in terms of Schemes for Sharing a Communication Medium; and portrait advantages and disadvantages of different types of networks. Finally explain relation between Carrier Sensing Hardware and Carrier Sensing Networks.
Mechanical contractors also concentrate in the added exclusive great equipment jobs. Maybe you want a conveying method or manufacture line for a big factory. Or maybe you require latest industrial farm tools. A mechanical contractor should be on your list. One that has knowledge in your meadow can do the finest job and get you going in no instance at all.
Motor oil is a necessary element of all engines. It is used to lubricate and cool a variety of parts to make sure that wear and tear is minimized, and the possibility of a severe fault developing is thin. Most of us do not come into straight contact with motor oil separately from when checking the level in our vehicles a pair of times a year.
