WiFi standards: what’s available …
A number of customers have asked me what’s the data rate and wireless range for the different wireless, or WiFi standards. Here is a useful reference table that might help answer those questions.
|Type||Frequency||Data Rate||Indoor Range||Approx Range|
|[802.11a]||5 Ghz||54 Mbps||~35 meters||~100 meters|
|[802.11b]||2.4 Ghz||11 Mbps||~38 meters||~120 meters|
|[802.11g]||2.4 Ghz||54 Mbps||~ 38 meters||~140 meters|
or 5 Ghz
|248 Mbps||~70 meters||~140 meters|
|[802.11y]||3.7 Ghz||54 Mbps||~50 meters||~5000 meters|
Ghz = Gigahertz
Mbps = Megabytes per second
1 meter = 3.281 feet
Data rate = how fast your network can potentially go
Approx Range = maximum approximate range the signal can go if you are out in the open with minimal interference
If you are wondering why the indoor range is different from the approximate range, it is because the wireless signal weakens when you have objects in the way (e.g. furniture, metal equipment, walls etc.) . Signal interference may also occur when using common household appliances like Microwaves and cordless phones. Also, WiFi signal strength/ range may decrease depending on how your house is setup, the structure of your house/ building (the more metal beams, the worse your signal is) and/or where you put your wireless router. To make sure you are getting the WiFi standards and speeds you’re paying for, you can use an Internet speed test, like this one from speedron.com.
