IEEE 802.11ac is a wireless networking regulation that was implemented in 2013   by IEEE Standards Association to provide higher/ faster/ efficient data transmission rates in wireless local area networks.

The IEEE 802.11ac standard Combines dual bands 5 GHz and the traditional IEEE 802.11n 2.4 GHz

The Wi-Fi AC technology simultaneously auto optimizes the 5 GHz & 2.4 GHz bands to improve transmission rates at least 1 Gigabit per second and a single- link transmission of at least (500 Mbit/s). 500 megabits per second more details here

The Next generation wireless networking -IEEE 802.11ac enables new WLAN usage scenarios:

  • Simultaneous gaming, browsing, and streaming of HD video to multiple devices
  • Fast synchronization, sharing and backup of large data files.
  • Wireless display
  • Large/wide area deployments and automation

What is the difference between the 802.11ac and 802.11 n/g?

802.11 (n,g) WI-FI – a lot of  overlapping in the channels used in the transmission therefore a lot of interference that affects the performance of most networks.

802.11ac- WI-FI – has less interference, a lot more channels and higher data transmission speed and good network performance

Note- where there are many users, the 5 GHz have a short range compared to 2.4 GHz

802.11ac- WI-FI Supports backward compatibility. Hence devices with in built 2.4 GHz chipsets and Wi-Fi Adapters can be can s work perfectly with 802.11ac- WI-FI devices.

Setting up a Wi Fi- network like a pro – What you will need to know

  • How to optimize Wi-Fi network performance
  • How to selects the right channels ( faster) in 802.11n devices
  • How to deal with nearby interference
  • Routers to buy and what to consider before buying a routers

Understanding the 2.4 GHz (802.11n) & 5.GHz (802.11ac) Routers, and Access Points (AP) Channels

Majority of the Wi-Fi (wireless Networks) installations are still done in 802.11n (2.4 GHz)

All networking routers and access points adopting these standard operate between the frequencies of (2500MHz – 2400MHz)

The difference gives use range of 100MHz- split into 14 channels of 20 MHz each.

From the diagram above you notice that at least each frequency interferes with 2 to 4 frequencies

From the diagram above the best channels that do not have overlapping are 1, 6 and 11- they are well spaced apart they don’t overlap for a non MIMO set up- router/ Wi- Fi access point.

Applying to your 2.4 GHz Wireless Router/ AP

Now, you will realize in your wireless router interface the channel is set to auto,

You can select stick to 1,6 and 11  hence the 3 channels can deliver maximum throughput

Note: Using the 40MHz is suitable for isolated places only where airwaves are not congested

Setting up an efficient wireless network in a crowded place: offices and open

 

As discussed above, channels 1, 6 and 11 give the maximum efficiency for your wireless network

Check for interference- if you are using channel 1 and the neighboring office is using channel two then you will experience a poor performance of your network.

However, if you are separated by thick walls and far apart windows, the walls will do a good job in attenuating/ weakening the signals. Otherwise talk to your neighbors to use to set up the routers to use the channels 1, 6 and 11

You can use tools like VISTUMBLER to help you find the clearest channel

Applying to your 5.0 GHz (802.11ac Next Generation Wi-Fi) Wireless Router/ Access Point)

 

The AC routers and access points have higher frequencies, and have up to 23 channels, hence less interference.

Most 802.11ac MIMO routers or Access points have inbuilt to choose the best channels and modify output power to maximize efficiency and reduce interference

5.0 GHz allow use of up to 40, 80 and 160 MHz channels.

If your router has MIMO technology, let it do the optimization for you.

Higher frequencies get attenuated easily, Therefore with interference AC routers will perform better but have a limited range.
