How to wireless network is something I need to share for all of you. In these days, many people working on the move, wether they are marketing, sales or business owner. for those mobile users wireless device is the only option device they have to do their jobs while away from the office. Sometimes these professional bring their work at home too, so they need network systems of their own.For those who’s not familiar with IT think setup a network installation could be a daunting task as they don’t know where to start and what todo. So for people who don’t know anything about technology could start from making some checklist about their needs. First list all you need from network systems, such as printer sharing, file sharing, gamings for kids and even internet sharing. After your list complete look again to see what is important to your goals. Then you need to create another list of peripheral that you need to connect it to your wireless network.

Now based on the list you make we can look what kind of peripheral you have that compatibel with your network design. From here you can measure how much money you need to spend on building your wireless network. After you create your budget then you may look some brands that suits your needs and off course you need to consider about compatibiliy issue for your hardware since you need to grow your wireless network as you update your devices.

For wireless network installation you can follow instruction on manual that comes with your hardware just look on how to. Wireless network is the simplest network systems to set up by your own. But if you feel confused and need some advice, contacting a network installer professional is your only option as these professionals has the ability to run network installation and also can advice you to choose the best network you need within your budget.

Wireless network
From Wikipedia, the free encyclopedia
Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes is implemented without the use of wires.[1] Wireless telecommunications networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” of the network.
Types
Wireless PAN
Wireless Personal Area Network (WPAN) is a type of wireless network that interconnects devices within a relatively small area, generally within reach of a person. For example, Bluetooth provides a WPAN for interconnecting a headset to a laptop. ZigBee also supports WPAN applications.[3]
Wireless LAN
Wireless Local Area Network (WLAN) is a wireless alternative to a computer Local Area Network (LAN) that uses radio instead of wires to transmit data back and forth between computers in a small area such as a home, office, or school. Wireless LANs are standardized under the IEEE 802.11 series.

* Wi-Fi: Wi-Fi is a commonly used wireless network in computer systems to enable connection to the internet or other devices that have Wi-Fi functionalities. Wi-Fi networks broadcast radio waves that can be picked up by Wi-Fi receivers attached to different computers or mobile phones.
* Fixed Wireless Data: This implements point to point links between computers or networks at two locations, often using dedicated microwave or laser beams over line of sight paths. It is often used in cities to connect networks in two or more buildings without physically wiring the buildings together
Wireless MAN
Wireless Metropolitan area networks are a type of wireless network that connects several Wireless LANs.
* WiMAX is the term used to refer to wireless MANs and is covered in IEEE 802.16d/802.16e.
Mobile devices networks
In recent decades with the development of smart phones, cellular telephone networks have been used to carry computer data in addition to telephone conversations:
* Global System for Mobile Communications (GSM): The GSM network is divided into three major systems: the switching system, the base station system, and the operation and support system. The cell phone connects to the base system station which then connects to the operation and support station; it then connects to the switching station where the call is transferred to where it needs to go. GSM is the most common standard and is used for a majority of cell phones.[4]
* Personal Communications Service (PCS): PCS is a radio band that can be used by mobile phones in North America and South Asia. Sprint happened to be the first service to set up a PCS.
* D-AMPS: D-AMPS, which stands for Digital Advanced Mobile Phone Service, is an upgraded version of AMPS but it is being phased out due to advancement in technology. The newer GSM networks are replacing the older system.

Wireless networks have had a significant impact on the world as far back as World War II. Through the use of wireless networks, information could be sent overseas or behind enemy lines easily, efficiently and more reliably. Since then, wireless networks have continued to develop and their uses have grown significantly. Cellular phones are part of huge wireless network systems. People use these phones daily to communicate with one another. Sending information overseas is possible through wireless network systems using satellites and other signals to communicate across the world. Emergency services such as the police department utilize wireless networks to communicate important information quickly. People and businesses use wireless networks to send and share data quickly whether it be in a small office building or across the world.[5]
Another important use for wireless networks is as an inexpensive and rapid way to be connected to the Internet in countries and regions where the telecom infrastructure is poor or there is a lack of resources, as in most developing countries.
Compatibility issues also arise when dealing with wireless networks. Different components not made by the same company may not work together, or might require extra work to fix these issues. Wireless networks are typically slower than those that are directly connected through an Ethernet cable.
A wireless network is more vulnerable, because anyone can try to break into a network broadcasting a signal. Many networks offer WEP – Wired Equivalent Privacy – security systems which have been found to be vulnerable to intrusion. Though WEP does block some intruders, the security problems have caused some businesses to stick with wired networks until security can be improved. Another type of security for wireless networks is WPA – Wi-Fi Protected Access. WPA provides more security to wireless networks than a WEP security set up. The use of firewalls will help with security breaches which can help to fix security problems in some wireless networks that are more vulnerable.
