When comparing other equipment from different manufacturers, you will want to compare "apples to apples", so look at their specs - usually they are rated in dbm. Look at this chart to compare their dbm rating to our transmit or receive power in miliwatts:

40 dBm 10.00 watts  
36 dBm 4.00 watts .
30 dBm 1.00 watts  
27 dBm 500 milliwatts  
26 dBm 400 milliwatts  
25 dBm 320 milliwatts  
24 dBm 250 milliwatts  
23 dBm 200 milliwatts  
22 dBm 160 milliwatts  
21 dBm 130 milliwatts  
20 dBm 100 milliwatts  
15 dBm 32 milliwatts  
10 dBm 10 milliwatts  
5 dBm 3.2 milliwatts  
4 dBm 2.5 milliwatts  
3 dBm 2.0 milliwatts  
2 dBm 1.6 milliwatts  
1 dBm 1.3 milliwatts  
0 dBm 1.0 milliwatts

How does the type of Security or Password settings affect bandwidth?

Here is a good example

Let's talk about Bandwidth and Netflix.

We have had many questions about how much bandwidth is consumed by streaming video from sites such as Netflix, and here is the breakdown on a 1 user scenario - naturally, you will want to multiply these figures times the number of user you think will stream videos at your property:

Here is a good example provided by Verizon FIOS -

download bandwidth required
and another useful calculation:

Netflix Movies (HD): These guys are around 3.8Mbit, which means it's about 3600MB for a 2 hour HD movie.
Netflix Movies (SD): Each of these movies are around 500-700MB each, depending on the length of the movie.
Netflix TV Shows (HD): A 30-minute TV show will be about 1500MB.
Netflix TV Shows (SD): A 30-minute TV show will be about 400MB.

These numbers are very important when determining how much bandwidth you need and how much you are giving your wireless connections. AND THESE NUMBERS DO NOT TAKE INTO CONSIDERATION NORMAL WEB BROWSING AND EMAIL, ETC.

Here is a good example:
2 guests streaming a video, 5 guests surfing the web, office using internet for reservations, etc and your ISP (Internet Provider) is delivering 10 MBS of bandwidth to your wired connection. Expect some "Free Air Loss" for wireless connections (say 10%, or 1 MBPS). This give your users 9 MBPS total available bandwidth.
A Netflix HD movie takes up almost 1 Gigabit per second - per user, so 2 users are getting 2 Mbits/s - leaves less than 7 Mbps for anyone else, and even then, the "streaming video" will stop and start.

 WiFi Setup:
There are many ways to set up a wi-fi system, but some basic questions must be answered to begin your installation such as:
  • How big is the area that needs coverage?
  • Will there be line of sight betweent the main Access Point and the client or repeater?
  • Do I need a high power transmitter to get the most throughput (not bandwidth) at the far end, or just enough power to cover the area?
  • What should the antenna pattern be - 30º, 90º, 180º 360º ?
  • Is one transmitter and one antenna enough to support the number of users?
If you have the answers to these basic questions, we can certainly help you in your deployment. For an idea of different setup scenarios, look at these:
