Navini Networks’ WiMax technologiesIEEE

Navini Networks is committed to developing, supporting and implementing operator-accepted standards for wide-area wireless broadband networks, as it is our belief that standards are necessary to facilitate the healthy growth of this industry. While Navini's Ripwave system is based on all relevant IP and WAN standards, there are no air interface standards available today for wide-area wireless broadband systems that meet the following operator requirements:

  • Indoor or outdoor use with no external or window-mount antennas required
  • Zero-install at end-user location - simple, plug-and-play end-user devices
  • Non-line-of-sight operation
  • Portable/Mobile Broadband
  • Operator-driven standards based on technology with commercial success

To this end, Navini is an active participant in two standards committees: TIP1.4, an ANSI working group and IEEE 802.16e. Both standards initiatives encompass technology that will meet Operator requirements for indoor use, zero-install modems at end-user locations and non-line-of-sight operation.

T1P1.4
This is a working group of the T1 committee of ANSI, accredited telecom systems standards-setting organization which focuses on functions and characteristics to interconnect and interoperate communications networks and operation support systems between virtually all parts of a complete end-to-end network - from carrier equipment to end-user equipment to information providers, ISP and application or enhanced service providers. T1 is also responsible for international coordination with the ITU. The T1P1 subcommittee is responsible for wireless and mobile systems; it is an operator-focused standards-setting body with strong vendor participation.

This working group is focused on Wireless Wideband Internet Access (WWINA) with the following attributes :

  • Optimized for high-speed packet data services > 1 Mbps
  • Defines a non-line-of-sight wireless Internet air interface
  • Supports full screen portable devices (beyond 3G handset devices)
  • Improved performance over high-mobility (3G) systems
  • Embraces both fixed and nomadic wireless broadband access

IEEE 802.16e

The 802.16e is a task group of the IEEE 802.16 Working Group on Broadband Wireless Access Standards, which develops standards and recommended practices to support the development and deployment of Broadband Wireless Metropolitan Area Networks. IEEE 802.16 is a unit of the IEEE 802 LAN/MAN Standards Committee, the premier transnational forum for wireless networking standardization. EEE 802 LAN/MAN standards committee, focusing on Layers 1 and 2 of the OSI (Open Systems Interconnect) reference model. The IEEE 802 standards committee is a computer industry-driven standards body for developing LAN standards, but has been expanded to also incorporate MAN standards as well. This committee is a vendor-focused standards body with operator participation.

The IEEE 802.16e task group focuses on developing standards to support vehicular speed mobility with handoffs in the 2 to 6GHz frequency range. The group provides the following attributes:

  • Optimized for IP data with peak user data rates > 1 Mbps
  • Supports fixed and vehicular mobility up to 75 miles per hour
  • Targets spectral efficiencies, sustained user data rates and numbers of active users significantly higher than existing mobile systems
  • Support fix as well as true mobile wireless broadband access, a future requirement of operators
  • Operates in the 2 to 6Ghz frequency Range with bandwidth > 5MHz
  • Optimized for low latency data applications
