Wi-Fi is a standard device in the lives of most people, but many users do not really understand what they are using and how it works. While Wi-Fi is extremely useful for all your laptop for wireless internet on your smartphone, it is not without risks. It is essential that you understand how wireless networks work, both at home and in public to keep your information and devices securely. These common questions will give you a look at what you need to know.
What is WiFi?
Wi-Fi is a type of wireless network technology. It allows you to connect your device to the Internet without wires. You can configure a wireless connection in your home or connect to Wi-Fi. There are potential dangers in using the Wi-Fi, such as slower speeds of access and the potential risks security, which are discussed later.
Wi-Fi is provided by a router. Your computer or other device will transmit data via a radio signal. The router takes the data, decodes it and sends to the Internet via its wired Ethernet connection. The router communicates with the connected device with its own radio signal, so your Internet connection is established.
802.11 networking What are Standards?
Wi-Fi routers are classified as 802.11 networking standards developed by the Institute of Electrical and Electronics Engineers (IEEE). These standards define the type of coding used, the maximum speed of the router, and indoor range of the router. Wireless standards apply both 2.4 gigahertz (GHz) and 5 GHz frequency bands public. The essential characteristics of each standard are:
- 802.11a - 5 GHz transmission, up to 54 megabits (Mbps) of data per second, orthogonal frequency division multiplexing (OFDM) encoding, 95- feet inside. range
- 802.11b -. transmission 2.4GHz, up to 11Mbps, Direct Sequence Spread Spectrum (DSSS) encoding, indoor range of 150 feet
- 802.11g - 2.4 GHz transmission, up to 54 Mbps, OFDM, indoor beach 170 feet
- 802.11n - .. 2.4 or 5 GHz transmission, 150 Mbps per antenna, OFDM, indoor range 230 feet
- 802.11ac - 5 GHz transmission, 433 mbps per antenna, OFDM, the indoor range is 230 feet.
How do I choose a wireless router?
There are two types of wireless routers on the market today. The current standard is 802.11n. These routers transmit on both frequencies 2.4 GHz and 5, although most users find the 5 GHz band less cluttered and more efficient. Using multiple antennas, these routers can transmit much more data than their predecessors.
There are also 802.11ac routers on the market. They are much faster, but also more expensive. These routers use multiple antennas as well, and each can support more than double Mbps of an antenna in an 802.11n router. Almost all hardware supports standards, so you can choose the router with the label capacity and price that best suit your needs.
How can I protect my wireless network?
Security is a major concern with any device that connects to the Internet. Your wireless router comes with integrated safety functions, but you should know how to use them. Your WEP or WPA router. If you can, WPA is far superior. With keys that change regularly, WPA makes it incredibly difficult to hack your Wi-Fi network.
Although your router has undoubtedly encryption features, they are usually turned off for shipping. Make sure you enable active encryption. Do not assume that it works. Run a firewall to computers connected to your Wi-Fi network for added security.
How can I stay safe on Public Wi-Fi?
Public Wi-Fi is incredibly useful, but it opens up a world of new security risks. Protection software and a firewall is essential if you use the Wi-Fi on your device. The safest way to use an Internet connection is a virtual private network (VPN). A VPN encrypts your data and creates a secure tunnel that you can pass through. Using a VPN like Hotspot Shield free you from many of the concerns of the use of Wi-Fi, offering a secure connection, you can use without worry.
Free Hotspot Shield VPN is available for your mobile (Android, iOS, Windows Phone) and desktop (Windows and Mac). And as soon as your like an extension of your browser (Chrome and Firefox). Stop worrying about your connection, and start accessing your favorite content without geographical restrictions now:
Are All Hotspots WiFi created equal
There is a Wi-Fi in most of the public space, but your device can not always automatically connect to those networks. Some places offer free Wi-Fi, but others require you to pay for the service or pay a guest. Hotels, for example, can provide a Wi-Fi connection, but typically provide the password for people staying on the property. While most Wi-Fi hotspots are legitimate, you should be aware of the potential to appeal to networks set up by hackers that will use the connection to try to steal your data.
Your data is vulnerable even on a legitimate Wi -Fi network if it is not encrypted. A secure website with https: // prefix encrypts data for that particular site. Wired reliable secure connection encrypts all data sent over the network, but most of the public access points do not do that. Using Hotspot Shield VPN, you can be assured that all your information is encrypted.
With a secure connection, Wi-Fi has the potential to stay connected to the world almost everywhere. With a smartphone, you have the unlimited potential of the Internet in your pocket.
