Wireless Frequently Asked Questions

As part of CORE Cabling’s emergence in the wireless installation market, we have compiled a list of questions we receive on a regular basis regarding wireless. If you have any questions you’d like to ask, let us know via email, or please post them on our LinkedIn page and we’ll get back to you as soon as possible!


The Wi-Fi Alliance is a non-profit organization responsible for the testing and certification of IEEE 802.11  devices for Interoperability between them. Basically, when a device is certified by the Wi-Fi Alliance, everyone is speaking the same language and using the same standards for communicating.

WHAT IS IEEE 802.11?

The IEEE (Institute of Electrical and Electronics Engineers) develops and maintains the standards under the banner known as 802.11. The most widely known standards are 802.11B, 802.11G, 802.11A and 802.11N.

WHAT ARE 802.11 A,B,G,N?

  • 802.11A operates in the 5Ghz band and supports an aggregate speed up to 54 Mbs (Mega Bytes per Second)
  • 802.11B operates in the 2.4Ghz band and supports speeds up to11 Mbs
  • 802.11G operates in the 2.4Ghz band and supports speeds up to 54 Mbs
  • 802.11N operates in the 2.4 and 5 Ghz band and supports speeds up to 150 Mbs


Multi-path is when the generated RF wave is disrupted by Reflection, Absorption, Refraction, Diffraction and Scattering which causes the same RF wave to arrive at the Device at different times. This causes severe damage to the received signal and can bring  a 802.11 A/B/G network to a crawl.
