How Can I Amplify Wireless Coverage Indoors and Outdoors?

[LucasTetrick]

I created a wireless coverage map using a device.
Does my coverage map apply just for that device or does that coverage apply to other devices?

I want to improve wireless coverage both indoors and outdoors.
What is the best way to do that?
Do I need a device for both indoors and outdoors to improve the signal strength?

Money is not an issue. I want the best solution.
Thank you!

WiFi range is limited by two primary factors

• Frequency (lower travels further)
  
• RF power output

Max range is therefore achieved by staying in the 2.4ghz band and not allowing the newer 5ghz AND using a wifi router with good RF output. It seems to follow that the higher the RF output, the shorter the life of the router.

The MIMO (multiple-in, multiple-out) class routers (ie has more than one antenna)
will deliver the best.

There are Range Extenders which are just 'repeaters' and boost the RF from that specific location.

If you daisy chain a primary, one secondary and add a range extender, I suggest using the same SSID for each, but unique RF channels to reduce interference.
{eg primary on 1, secondary on 6, extender on 11}

NOW the $64 question: What's the need for range over open ground?
