Many kind of of our customers involved us for guidance on which WiFi standard would certainly be best for their specific product advancement needs. In this short article, we look at the development of wiremuch less criteria, and also the pros and cons of each.

You are watching: 802.11b/g/n (1x1) wi-fi® and bluetooth® 4.2 combo



In 1997, the Institute of Electrical and Electronics Engineers (IEEE) produced the first WLAN standard. They called it 802.11 after the name of the group created to oversee its breakthrough. Unfortunately, 802.11 just supported a maximum network bandwidth 2 Mbps, as well sluggish for a lot of applications.


IEEE broadened on the original 802.11 standard in July 1999, developing the 802.11b specification. 802.11b supports bandwidth as much as 11 Mbps, equivalent to conventional Ethernet.

802.11b supplies the very same unregulated radio signaling frequency (2.4 GHz) as the original 802.11 typical. Vendors regularly like utilizing these frequencies to reduced their production costs. Being unregulated, 802.11b gadgets have the right to have actually interference from microwave ovens, cordless phones, and other appliances making use of the very same 2.4 GHz array. However, by installing 802.11b gadgets an adequate distance from other appliances, interference have the right to easily be avoided.

Pros of 802.11b - lowest cost; signal array is good and not conveniently obstructed Cons of 802.11b - slowest maximum speed; house appliances may interfere on the unregulated frequency band also


While 802.11b was in advancement, IEEE produced a 2nd expansion to the original 802.11 traditional dubbed 802.11a. Due to the fact that 802.11b got in popularity a lot faster than did 802.11a, some folks think that 802.11a was created after 802.11b. In reality, 802.11a was produced at the exact same time. Due to its greater expense, 802.11a is generally uncovered on service networks whereas 802.11b much better serves the house market.

802.11a supports bandwidth as much as 54 Mbps and also signals in a regulated frequency spectrum approximately 5 GHz. This better frequency compared to 802.11b shor10s the range of 802.11a netfunctions. An 802.11a access point transmitter may cover less than one-fourth the area of a comparable 802.11b/g unit. The better frequency additionally indicates 802.11a signals have more challenge penetrating walls and various other obstructions.

Because 802.11a and also 802.11b use various frequencies, the 2 innovations are incompatible through each various other. Some sellers sell hybrid 802.11a/b netoccupational gear, however these commodities merely implement the 2 criteria side by side, as the connected devices have to use either one or the various other.

Pros of 802.11a - rapid maximum speed; regulated frequencies prevent signal interference from various other tools Cons of 802.11a - highest possible cost; shorter array signal that is even more quickly obstructed


In 2002 and 2003, WLAN assets sustaining a more recent traditional called 802.11g arised on the sector. 802.11g attempts to integrate the finest of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54 Mbps, and also it uses the 2.4 GHz frequency for higher array. 802.11g is backwards compatible through 802.11b, interpretation that 802.11g access points will certainly work-related with 802.11b wireless network adapters and also vice versa.

Pros of 802.11g - rapid maximum speed; signal variety is excellent and not easily obstructed Cons of 802.11g - costs more than 802.11b; appliances may interfere on the unregulated signal frequency


802.11n (also periodically known as "Wiremuch less N") was designed to improve on 802.11g in the amount of bandwidth sustained by making use of multiple wireless signals and antennas (dubbed MIMO technology) instead of one. Indusattempt standards teams ratified 802.11n in 2009 through specifications offering for as much as 300 Mbps of netjob-related bandwidth. 802.11n additionally uses somewhat better selection over previously Wi-Fi criteria because of its boosted signal intensity, and it is backward-compatible via 802.11b/g gear.

Pros of 802.11n - fastest maximum rate and ideal signal range; even more resistant to signal interference from outside sources Cons of 802.11n - traditional is not yet finalized; costs more than 802.11g; the use of multiple signals might substantially interfere with nearby 802.11b/g based networks


The newest generation of Wi-Fi signaling in renowned use, 802.11ac uses dual band also wireless technology, sustaining simultaneous connections on both the 2.4 GHz and 5 GHz Wi-Fi bands. 802.11ac offers backward compatibility to 802.11b/g/n and bandwidth rated as much as 1300 Mbps on the 5 GHz band plus as much as 450 Mbps on 2.4 GHz.

Pros of 802.11ac – offers enhanced bandwidth and more adaptability via simultaneous connection support; backwards compatibility enables usage of existing technologies Cons of 802.11ac –dual bands intend boosted cost; still prone to interference on the 2.4GHz frequency
