Help Me Choose: Wireless

 
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


 For wireless access, you'll need:
  • Broadband Internet access like DSL or cable (not dial-up)
  • A wireless router to connect to your cable or DSL modem
  • An internal wireless card or USB adapter for your desktop


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)
    • 3x3 = 3 send antennas and 3 receive antennas (450Mbps throughput for 802.11n / 1.3Gbps for 802.11ac)

Wireless Standards
  • Current generation of Wi-Fi standard is 802.11n
  • Starting in 2013, a new standard will launch called 802.11ac
  • Tri-band WiFi combines 2.4GHz, 5GHz, and 60GHz into a single module. The third WiFi band over 60GHz is called WiGig which provides up to 4.6Gbps up to 10 meters away (near range)
  • WiGig is currently used for docking station applications which provides the ability to connect to a WiGig based docking station that enables connectivity to Ethernet, USB, HDMI, Display Port, or VGA port
