Wireless Networking Standards

Wireless networking is becoming increasingly important to businesses, both small and large. Use this chart to make sense out of all the wireless local-area network standards.

Use this wireless networking standards chart to get quick information to help you differentiate between the available wireless networking standards and choose which standard might be the right fit for your business. See the links below the chart for further information on wireless networking standards.

Pros/Cons & More Info

IEEE 802.11 Up to 2Mbps in the 2.4GHz band FHSS or DSSS WEP & WPA This specification has been extended into 802.11b.
IEEE 802.11a
(Wi-Fi)
Up to 54Mbps in the 5GHz band OFDM WEP & WPA Products that adhere to this standard are considered "Wi-Fi Certified." Eight available channels. Less potential for RF interference than 802.11b and 802.11g. Better than 802.11b at supporting multimedia voice, video and large-image applications in densely populated user environments. Relatively shorter range than 802.11b. Not interoperable with 802.11b.
IEEE 802.11b
(Wi-Fi)
Up to 11Mbps in the 2.4GHz band DSSS with CCK WEP & WPA Products that adhere to this standard are considered "Wi-Fi Certified." Not interoperable with 802.11a. Requires fewer access points than 802.11a for coverage of large areas. Offers high-speed access to data at up to 300 feet from base station. 14 channels available in the 2.4GHz band (only 11 of which can be used in the U.S. due to FCC regulations) with only three non-overlapping channels.
IEEE 802.11g
(Wi-Fi)
Up to 54Mbps in the 2.4GHz band OFDM above 20Mbps, DSSS with CCK below 20Mbps WEP & WPA Products that adhere to this standard are considered "Wi-Fi Certified." May replace 802.11b. Improved security enhancements over 802.11. Compatible with 802.11b. 14 channels available in the 2.4GHz band (only 11 of which can be used in the U.S. due to FCC regulations) with only three non-overlapping channels.
IEEE
802.16
(WiMAX)
Specifies WiMAX in the 10 to 66 GHz range OFDM DES3 and AES Commonly referred to as WiMAX or less commonly as WirelessMAN or the Air Interface Standard, IEEE 802.16 is a specification for fixed broadband wireless metropolitan access networks (MANs)
IEEE
802.16a
(WiMAX)
Added support for the 2 to 11 GHz range. OFDM DES3 and AES Commonly referred to as WiMAX or less commonly as WirelessMAN or the Air Interface Standard, IEEE 802.16 is a specification for fixed broadband wireless metropolitan access networks (MANs)
Bluetooth Up to 2Mbps in the 2.45GHz band FHSS PPTP, SSL or VPN No native support for IP, so it does not support TCP/IP and wireless LAN applications well. Not originally created to support wireless LANs. Best suited for connecting PDAs, cell phones and PCs in short intervals.
HomeRF Up to 10Mbps in the 2.4GHZ band FHSS Independent network IP addresses for each network. Data is sent with a 56-bit encryption algorithm. Note: HomeRF is no longer being supported by any vendors or working groups. Intended for use in homes, not enterprises. Range is only 150 feet from base station. Relatively inexpensive to set up and maintain. Voice quality is always good because it continuously reserves a chunk of bandwidth for voice services. Responds well to interference because of frequency-hopping modulation.
HiperLAN/1 (Europe) Up to 20Mbps in the 5GHz band CSMA/CA Per-session encryption and individual authentication. Only in Europe. HiperLAN is totally ad-hoc, requiring no configuration and no central controller. Doesn't provide real isochronous services. Relatively expensive to operate and maintain. No guarantee of bandwidth.
HiperLAN/2 (Europe) Up to 54Mbps in the 5GHz band OFDM Strong security features with support for individual authentication and per-session encryption keys. Only in Europe. Designed to carry ATM cells, IP packets, Firewire packets (IEEE 1394) and digital voice (from cellular phones). Better quality of service than HiperLAN/1 and guarantees bandwidth.
OpenAir Pre-802.11 protocol, using Frequency Hopping and 0.8 and 1.6 Mb/s bit rate CSMA/CA with MAC retransmissions OpenAir doesn't implement any encryption at the MAC layer, but generates Network ID based on a password (Security ID) OpenAir is the proprietary protocol from Proxim. All OpenAir products are based on Proxim's module.
