What You Need to Know About WiMAX 802.16

July 26, 2018 at 8:00 AM

 

In the IEEE’s world of standards, 802.16 is dedicated to the global deployment of broadband metropolitan area networks. The technology for this standard has been named WiMAX (Worldwide Interoperability of Microwave Access), it is used for long-rage wireless networking for mobile and fixed connections. Though not as popular as Wi-Fi or LTE, WiMAX has much to offer.

 

When compared to similar technologies, WiMAX offers low cost and increased flexibility. It is an OFDMA-based, all IP, data-centric technology ideal for use in 4G mobile. WiMAX can be installed with shorter towers and less cabling, which supports city or country-wide non-line-of-sight (NLoS) coverage. This cuts down installation time and saves on cost when compared to standard wired technology such as DSL. In addition to fixed connections, WiMAX service is offered through a subscription for access via devices with built-in technology. Currently, WiMAX is in many devices such as phones, laptops, Wi-Fi devices and USB dongles.

 

WiMAX is capable of speeds up to 40 Mbps over a distance of several miles. WiMAX can also provide more than just internet access, it can deliver video and voice transmissions and telephone access. All of these capabilities, plus lower cost and faster installation times make it an attractive option for areas where wired internet is too costly or not available. WiMAX can also be used in several other ways: as a backhaul to transfer data through an internet network, as a replacement for satellite internet for fixed wireless broadband access and for mobile internet access comparable to LTE.

 

After many revisions, WiMAX has now evolved into its most current version: WiMAX Advanced, which is backwards-compatible with previous versions (WiMAX Release 1.0 and 2.0). WiMAX Advanced utilizes all of the same capabilities while providing 100 Mbps mobile speeds and 1 Gbps fixed station speeds. Plus, WiMAX Advanced supports additional devices and broadband wireless access technologies, MIMO, beamforming and radio access technologies for operation within a multi radio access network. WiMAX is managed by the WiMAX forum, a non-profit group that certifies and endorses wireless products that are compatible with the 802.16 standard, these include WiMAX Advanced, AeroMACS and WiGRID.

 

Of course, there are drawbacks to WiMAX, speeds can get slower as the source gets further away. Also, when multiple users are connected at the same time, performance can suffer. WiMAX might never be as popular as Wi-Fi, but there are plenty of benefits that make it a good option to consider.
