Modern wireless Internet services have greatly helped people enhance the way they do their work. Their role has become so crucial that businesses may become paralyzed when they cease to become available.
There are three general types of wireless Internet services. These are cellular Internet, hotspot wireless Internet, and satellite Internet.
Cellular Internet is made possible by a cellular architecture that is made up of a backbone network. A group of cell phones located in a certain area can communicate using a common base station called a cell. Cells are made to overlap each other to ensure continuity of communication. Mobile units of different cellular Internet providers are able to connect with each other using the base stations and the backbone network of each provider.
To further facilitate communication among cell phones using different providers, a standard system has been developed. This is called Global System for Mobile Telecommunications, which has made roaming possible.
Hotspot wireless Internet, on the other hand, is useful for enabling Internet access in certain areas that are called hotspots. Examples of these areas are airports, coffee shops, and hotels. Internet access in these hotspots may come with a fee, but some offer it for free to further attract visitors in their respective areas.
Wireless local area network standards are used by hotspot wireless Internet. An example of such a standard is IEEE 802.11b, which allows connections at speeds of more than 10 megabits per second.
Meanwhile, satellite Internet from anywhere is being used for rescue services and other industries such as mining, transportation, and traveling. This provides better quality than traditional radio systems. To enable such service, a user needs to have an antenna that is aimed at the correct satellite and a modem that will be used to connect to the computer. The architecture of satellite Internet consists of an elliptical satellite dish, modems, and coaxial cables between the dish and the modems. The satellite dish needs to be mounted to a high place to ensure faster transmission of data.
Wireless Internet has indeed been crucial in helping businesses grow and governments improve. Because of its practical uses, it has also become a tool for personal use. One can only expect further improvements to be introduced to wireless Internet because, as time passes by, the demand for it will continue to rise.

February 7th, 2010Ethernet Internet Service Package
January 26th, 2010
Many companies are now relying and depending on the use of internet. This is because Internet offers and delivers services with high-quality, high-speed connections for companies or even individuals who depends on the Internet for critical applications. All you have to do is simply plug the switch of router into the RJ-45 Ethernet connector that your service provider have installed. Right away, you are connected to the Internet at broadband speeds. Ethernet Internet uses the same protocol that runs on Local Area Network connection.
Nowadays, there are varieties of broadband Internet access through DSL, Cable Internet, Wireless ISPs, or T1 lines. There are many service providers that offer a comprehensive suite of Internet options, not only traditional connections (TDM) from T1 to OC48 but also Ethernet connections from 10 Mbps ports to 10 Gbps ports. Internet Services (EIS) transport Internet access over a full-duplex Ethernet connection. With Ethernet Internet connection, you gain the ability to cost effectively connect your network to the Internet using a familiar technology. And for this reason, you can easily expand to meet your company’s growing bandwidth requirements.
Ethernet Internet is available through this service package:
Ethernet – 2M to 10M in 2M increments
Fast Ethernet* – 2M to 100Mbps in 2M increments up to 10M, then 5M increments up to 100M
Gigabit Ethernet* – 50M to 1000M in 10M increments to 100M, 25M increments to 250M, 50M increments to 1000M
10 Gigabit Ethernet* – ICB Only – 1000M to 10,000M in 1000M increments
As repeater driven, meaning – signal is digitally reestablished every 6000 feet, Ethernet Internet service is available several miles from telephone central offices.

Metro Ethernet Service and Providers – The Basic Concept of LAN
December 1st, 2009
Different Metro Ethernet services include various concepts which are covered in terms of data in the metro. Concepts such as the forms in which an Ethernet service can take shape, for example “retail” or traditional private line services and “wholesale” where a carrier may sell a large transport pipe to many smaller service providers.
In both of these scenarios many different customers will be sharing the same Metro Ethernet equipment and infrastructure. Even so this is not an issue as each client is issued with an isolated circuit, so traffic is not all bundled up together. This service is the business of selling transport pipes in which the customer receives a well defined SLA, and this is dictated by circuit they purchase.
If switching or packet multiplexing is applied as in the case of Ethernet Transport, EOS, and RPR, things become slightly different. Different customer packets will be “multiplexed” in the same pipe, which means they share the same bandwidth. There is nothing physical which divides one customer’ service from another, in other words no hard boundaries. The only boundaries which exist are logical and this means traffic is separated by means of “packet queuing” this ensures QoS and definition for multiple services.
The service provider knows how to define and identify one customers’ traffic from another, when the network or pipe is shared and they are also able to identify as well as enforce the service which a particular customer has purchased. Specific bandwidth is allocated per the customers’ package and they are able to “transparently” move traffic for a specific customer between different locations. Scaling the number of customers is also important, as is deploying a VPN service for any-to-any connectivity.
Ethernet itself is the most widely used form of LAN or Local Area Network technology. It was originally developed from a system known as Alohanet from the Palo Alto Research Center, which was further developed by Xerox, Intel and DEC. Typically this kind of network makes use of coaxial cables which are made up from pair of twisted wires. The most commonly used are 10BASE-T which provides up to10Mbps transmission speeds.
We also find Fast Ethernet which is known as 100BASE-T where we are looking at speed of 100 Mbps, a 1000Mbps speed is not unknown, and this provides and incredibly high level of support to the LAN. We also find Gigabit and 10 Gigabit Ethernet also.
It was named by one of the developers, a certain Robert Metcalfe, and it was name such because of the light-transmitting “ether” which was supposedly the way light traveled, or pervaded the Universe. By the same token the cabling or “ether” is also able to carry information throughout an entire network which could be considered to be its own little universe.
It is has become a very standard protocol to use for the purposes of communication, and believe it or not Robert Metcalfe invented this in 1973. Because Digital, Intel and Xerox were responsible for developing the first working models, the first standard model for Ethernet was known as “DIX” and it was this hard wired LAN which came into world-wide use. Now you have a little background on Metro Ethernet Service.
