    • Part 16: Air Interface for Broadband Wireless Access Systems Amendment 1: Multihop Relay Specification
802.16-2012 – Air Interface for Broadband Wireless Access Systems

The standard specifies the air interface:

  • MAC – Medium Access Control (Layer 2)
  • Physical (Layer 1)

It enables the following:

  • Deployment of the WiMAX products
  • Originate competition in broadband access
  • Encourages consistent spectrum allocation all over the world
802.16p-2012 – Air Interface for Broadband Wireless Access Systems

Amendment 1 provides support for machine to machine applications.

802.16.1b-2012 Standard for WirelessMAN-Advanced Air Interface for Broadband Wireless Access Systems

Amendment 1 improves support for machine to machine applications.

802.16.2-2004 Recommended Practice for Local and Metropolitan Area Networks Coexistence of Fixed Broadband Wireless Access Systems

Recommendations for the design and deployment of fixed WiMAX networks. It covers the frequency spectrum 2 GHz – 66 GHz, but specifically 3.5 GHz, 10.5 GHz, 23.5 – 43.5 GHz.

802.16/Conformance04-2006 – Conformance to IEEE 802.16

Enables the WiMAX network also for the mobile wireless users.

What is WiMAX

WiMAX – Worldwide Interoperability for Microwave Access, is the wireless technology for longer distances. Sometimes it is called WiFi on steroids.

WiMAX Services

You can find two kinds of the WiMAX services NLOS WiMAX services (Non line of sight services) and LOS WiMAX services (line of sight).

More about the WiMAX networks and services you can read on What is WiMAX and How WiMAX Works.

Advantages and Disadvantages of  the WiMAX Technology

The biggest benefits of the WiMAX technology is that provides long range wireless access and it can serve great numbers of users at the same time.

The biggest WiMAX problems are high cost, delay and big power consumption.

802.16 – The Final Notes

IEEE 802.16 is a family of standards that defines the WiMAX networks and how it works. The WiMAX Forum is an organization which goal is to promote the WiMAX technology.
