Very Small Aperture Terminal (VSAT) Communication Networks Introduction Very Small Aperture Terminal (VSAT) communication networks are a form of satellite communication where business and industry can transmit data, voice and video around the world through a satellite link. Companies such as Walmart use VSATs to process data to and from their stores nationwide (Lawton, 1994). Understanding the basics of what constitutes a VSAT network and how it operates will establish a basis of knowledge
For Rectangular patch antenna, the length (L) of the patch is often (0.33330λ0< L < 0.50λ0), where (λ0) is the free space wavelength. The patch is chosen to be very thin such that (t<<λ0) (where (t) is the patch thickness). The height (h) of the dielectric substrate is usually defined (0.0030λ0 ≤ h ≤ 0.050 λ0). The dielectric constant of the substrate (Er) is normally in the range (2.20 ≤ Er ≤ 12). Microstrip
that uses portable terminals for telecommunication. The terminals will be connected to computers, laptops in remote areas to broadband internet. Broadband Global Area Network (BGAN): BGAN is global satellite internetwork that can uses portable terminals for telecommunication. The terminals used to connect computers, laptops to broadband internet in remote areas, even if as long as line-of-sight to the satellite exists, In anywhere terminal can be used. The Value of BGAN terminals is that different
1. Diverse demographics Maritime Industry is depended hugely on human capital, and diverse demographic is a common state of affair of the industry. The demographic composition depends on market trends, legislation and demographic realities such as local content requirements for operating in certain countries, etc. Having a diverse workforce and managing it effectively brings in huge advantages to the organization. We have around 30 nationalities working in our organization with varied gender, race
these antennas were considered to be energy storage devices but in this paper we have made use of the DRA antennas as radiators. These antennas have been described with their features which separates them from ordinary antennas, the features include small size, high efficiency etc. The DRA are compared to micro strip antennas in this review paper. Basically this paper gives an idea about the evolution of directive resonator antennas and their applications and the different DRA antennas are compared
The deployment of wireless technology has taken by both of the Giant company, FedEx and UPS in order to keep the company competitive advantage. The Bluetooth short – range wireless specification, 802.11b wireless LANs, and general packet radio service (GPRS) are the wireless solution for both big companies. These lead to the operational efficiency, saving cost – the critical business requirement, and increasing customer satisfaction while also doing more with the same resources. The devotement of
The Impact of Internet on Education A dusty, one-room schoolhouse on the edge of a village. An overworked teacher trying to manage a room full of boisterous children. Students sharing schoolbooks that are in perpetual short supply, crammed in rows of battered desks. Children worn out after long treks to school, stomachs rumbling with hunger. Others who vanish for weeks on end, helping their parents with the year-end harvest. Still others who never come back, lacking the money to pay for school uniforms
From early ages to present humanity always have been curious about space. With development on science humanity start to explore space in mid-twenty centuries. Thenceforward scientists have used enormous amount of money and effort for the space researches every year. However, most of the people think that scientist could not get enough information in spite of amount of effort they used in. People who do not know the real life application of space research deliberate that budget for space research
facilitate both the production of eggs and milk. The male tract is quite simple. The female tract has qualities similar to those of birds, though female echidnas also possess pouches. The monotreme egg is also very specialized and somewhat similar to a reptile egg. Platypuses and echidnas have very different behaviors when it comes to mating, but their genetics are quite similar. Monotremes possess a few large chromosomes and several unpaired microchromosomes. The descendants of the first radiation
