Help Me Choose: Wireless

• An internal wireless card is a small piece of hardware about the size of a credit card that plugs into your computer’s motherboard
• It enables your computer to find wireless connections in your coverage area — such as internet hotspots and home or office local networks as well as wireless devices — and connect to them without a cable
• The speed and range at which your computer can transmit and receive data is based on the wireless standard of your wireless card and the router your computer connects to

 

Wireless provides the simplicity of cable-free connectivity to the Internet, home or office local network, as well as to other wireless electronic devices such as printers, storage, wireless peripherals, and other computers on the network. Dell offers options for wireless connectivity whether you require a basic connection or the next generation in Wi-Fi access.

Wi_Fi


Wireless Terminology
  • Single Band (2.4 GHz)
    •  Single band supports only the 2.4GHz band
    • Lots of wireless devices (phones, computers, appliances, etc) use this band – therefore, it’s very “congested” or “noisey” and can inhibit performance
  • Dual Band (2.4 GHz + 5 GHz)
    • Dual band supports both the 2.4GHz and 5GHz band
    • 5GHz band is much less congested, therefore providing a better wireless experience especially for things like wireless display (WiDi / Miracast)
    • There are more & wider channels in the 5GHz band compared to 2.4GHz
  • Antenna Configurations
    • 1x1 = 1 send antenna and 1 receive antenna (150Mbps throughput for 802.11n / 433Mbps for 802.11ac)
    • 2x2 = 2 send antennas and 2 receive antennas (300Mbps throughput for 802.11n / 866Mbps for 802.11ac)
