Mobile WiMAX, MIMO-Based Coverage Enhancement Solution Debuts | Wireless IQ

Dekolink Wireless, Ltd. is today announcing an industry-first in-building repeater solution for the WiMAX market. The Deko2425-M WiMAX MIMO-based repeater can be implemented in mobile carriers' and other mobile WiMAX networks in the 2.5-2.7 GHz bands.

KT, LG-Nortel And Nortel Combine Expertise At Mobile Wimax Service Conformance Verification Center

Service Conformance Verification Center. The SCVC is built around Nortel’s WiMAX technology, comprised of Nortel’s WiMAX Base Transceiver Station (BTS) 5000 - a MIMO-powered solution, Access Service Network (ASN) Gateway, Connectivity Service Network (CSN), and WiMAX PCMCIA cards provided by Nortel’s multi-vendor ecosystem members. Nortel recently announced the WiMAX 4G Ecosystem Center of Excellence in Taiwan which will promote interoperability across WiMAX devices and applications such VoIP, video streaming and IPTV.

WRC-07 agenda item 1.4 | Ofcom

Summary of conclusions

1.1 The following points highlight Ofcom's main conclusions on candidate bands following a review of the responses to the consultation it published on WRC 07 agenda item 1.4 on 27 February 2007:

* Ofcom’s preference for the band 470 to 862 MHz is a co-primary mobile allocation in Region 1 in the table of allocations in Article 5 of the Radio Regulations;
* Ofcom supports a co-primary mobile allocation for the sub-band 3400 to 3800 MHz and an identification for IMT coupled with a requirement for an associated Resolution to reflect the need to provide appropriate protection for existing satellite use whilst facilitating access to the band for new use;
* In view of the emerging opposition from various European administrations to the sub-band 3800 to 4200 MHz Ofcom supports a position of no change to the table of allocations;
* For the other candidate bands, we have concluded that there is no need to change the position proposed in the consultation however the UK may wish to consider the merit in signing up to any "no change" proposals developed within Europe.

IEEE802.16 "WiMAX" Software Reference Designs

The solution scales from femtocells through microcells to sophisticated multi-sector basestations, with full support for mobility, MIMO and beam-forming. What’s more, it is completely software upgradeable, from certified 16d to 16e, Wave 2 and MIMO — and with a roadmap to 16j and 16m.

WiMax To Become Part of 3G Umbrella

WiMAX could become a sub-3G technology before 2008 thanks to pre- approval of proposals submitted by the IEEE and the WiMAX Forum to the International Telecommunication Union.

The 22nd meeting of the ITU Radiocommunication Sector (ITU-R) Working Party 8F (WP 8F) in Kyoto, Japan reached a significant milestone in its work when it forwarded for approval a new terrestrial radio interface for IMT-2000, "OFDMA TDD WMAN" as a specific subset of WiMAX. This new terrestrial radio interface complements the existing family of IMT-2000 radio interfaces and is in direct response to the demands of ITU Members to address the continuously growing wireless marketplace.

IMT-2000 radio interface expanded with OFDMA technology

Geneva, 31 May 2007 - The 22nd meeting of the ITU Radiocommunication Sector (ITU-R) Working Party 8F (WP 8F) in Kyoto, Japan reached a significant milestone in its work when it forwarded for approval a new terrestrial radio interface for IMT-2000, "OFDMA TDD WMAN" as a specific subset of WiMAX. This new terrestrial radio interface complements the existing family of IMT-2000 radio interfaces and is in direct response to the demands of ITU Members to address the continuously growing wireless marketplace.

WP 8F has delivered a number of key Recommendations and Reports that update and expand the family of IMT-2000 radio interfaces, establish the foundation for IMT-Advanced, and call for additional spectrum for IMT. It has woven together a definition, a recipe, and a roadmap foreseeing the future beyond 3G that is comprised of a balance between a market and services view, a technology view, and a spectrum view. Along with regulatory aspects, these are the key elements for business success in the wireless industry, and ITU-R continues to deliver value to industry and government.

Working under a mandate to address "systems beyond 3G", WP 8F progressed from delivering an initial vision to establishing a name for the future (IMT-Advanced) and set out principles for the process of development of IMT-Advanced. These deliverables stimulated research and development activities worldwide, spawned ideas on potential technologies, and promoted views on spectrum required to address a rapidly growing wireless world.

Clearwire Completes Acquisition of AT&T Mobile WiMAX Spectrum

Clearwire announced the completion of its acquisition of all the 2.5 GHz wireless broadband spectrum previously owned or controlled by AT&T Inc. and the former BellSouth.

With this acquisition and assuming closing of other pending spectrum purchases, Clearwire's U.S. spectrum holdings increased to approximately 14.0 billion MHz-POPs, covering an estimated 223 million people with varying depths of spectrum. In addition, Clearwire holds approximately 8.7 billion MHz-POPs of spectrum in Europe, covering approximately 199 million people. Clearwire holds one of the world's largest portfolios of next-generation wireless broadband spectrum in the frequency bands identified by the mobile WiMAX standard.
