What is WLAN modem?
Wireless network Modem (WLAN) is a radio frequency (RF) device that allows local computers to communicate wirelessly. It also allows all computers on the network to share one Internet connection. The traditional WLAN modem sits on the desktop to serve the network to a home, commercial building or the general national environment. There are also mobile wireless modems that provide an access point or hotspot on the go.
and WLAN modem comes with a built -in router for direct operation in the local network. The router monitors the origin of the requirements and reaction to the infusions to the appropriate machine by reading data packets with unique address information. The router also processes the requirements filed on and from the Internet when the connection is available.
In order to communicate with the WLAN modem, computers require a wireless network card. The card consists of a radio transmitter and a receiver, similar to the WLAN modem. Network card does not include because it is designed only for connecting one PCummer to the network. Network cards are usually internal, but external wireless network adapters can also be purchased.
wireless communication protocols are standardized so that competing manufacturers can produce products that will work together. Standards are set by the institute of electric and electronic engineers (IEEE), non -profit, international groups. The protocols are governed by the numeric designation 802.11, followed by a letter meaning the exact taste of the protocol. For example, 802.11a, 802.11b, 802.11g and 802.11n are four wireless standards, the last two are the latest incarnations. Wireless network cards must share at least one common standard 802.11 with WLAN modem to successfully replace data.
Wi-Fi ™ Alliance is an international group that supports wireless technology. Tocertifies presented products such as Wi-Fi ™ -compliant when these products meet strict standards Interopability. The products can then transfer the Wi-Fi ™ logo. The device that carries the logo is essentially guaranteed to cooperate for potentially smoother running networks. The actual Wi-Fi ™ network consists only of certified hardware.
Wi-Fi ™ certification is not free for the manufacturer, so the hardware approved by Wi-Fi ™ is more expensive. In general, businesses could opt for Wi-Fi ™, while extra money is probably unnecessary in most home networks. The WLAN modem, which is not certified, will usually be cheaper.
In addition to the desktop WLAN modem, a mobile access point or roaming hotspot is created by a wireless modem that is designed to go on the road. These compact modems come in different footsteps from USB Dongles to elegant cards and use cellular technology to ensure Internet access to multiple devices. Account with a cell carrier is required.
6 For the future investment is the best to buy a product that supports the latest standards even if ZPThe previous standard can also delay the need to update older cards or products.
