HDTV over Wi-Fi

HDTV over Wi-FiTelephonyOnline has an article speculating that wireless high definition television will be available this summer. Celeno Communications, an Israeli start-up backed by Cisco, manufactures Wi-Fi chips. Their semiconductors can make Wi-Fi networks robust enough to deliver multiple high-definition television (HDTV) streams to PCs, TV’s or other consumer electronics devices. Celeno’s technology would deliver on a significant part of the anywhere, anytime video promise.

Celeno’s OptimizAIR technology will work with existing receivers such as set-top boxes, uses the 5 GHz spectrum. OptimizAIR uses standard PHY and MAC layers. It uses proprietary algorithms that the company says can double the throughput of standard 802.11 Wi-Fi. It can also increase the range of the Wi-Fi signals as much as eight times. Celeno’s technology additions include Spatial Channel Awareness and Beam-Forming MIMO (multiple inputs, multiple outputs). The company said it can stream HD video 120 feet, through four brick walls and more than three floors.

Nortel Declares Bankruptcy

Chinese hackers had widespread access to Nortel's corporate computer networkUpdated 02-14-12 The Wall Street Journal reported that for nearly a decade before Nortel collapsed  Chinese hackers had widespread access to its corporate computer network.

According to the article, the hackers used seven passwords stolen from top Nortel executives, including the chief executive. The suspected Chinese hackers penetrated Nortel’s computers at least as far back as 2000 and over the years downloaded technical papers, research-and-development reports, business plans, employee emails, and other documents.

Updated 03-12-09 WirelessWeek is citing The Wall Street Journal is reporting that Nortel is in talks to sell its core wireless equipment business as well as a separate unit that builds telecom systems for offices, according to anonymous sources in the WSJ.

The WSJ reported that Nortel is talking to Nokia Siemens Networks, to sell its wireless business. Avaya and Siemens Enterprise Communications, a joint venture of Siemens and technology private equity firm Gores Group, are interested in the company’s enterprise unit. Cisco Systems reportedly looked at the enterprise unit but wasn’t expected to bid. Nortel declined to comment.

Nortel Declares Bankruptcy113-year-old Canadian technology firm Nortel filed for Chapter 11 bankruptcy today. Nortel’s losses in the third quarter ballooned to $3.41 billion and 1,300 people had to be let go. CEO and President Mike Zafirovski wrote on the company’s Website. “Most importantly, Nortel is still very much in business.

Next steps for the former Northern Telecom may include selling various business units or receiving a capital investment as a way to go private, According to Avi Cohen, managing partner at analyst firm Avian Securities, on TheStreet.com,The most likely bidders for Nortel’s assets are Ericsson, Huawei (002502), Nokia Siemens, and Cisco (CSCO). We believe Alcatel-Lucent (ALU) and Motorola are less likely bidders because they are struggling with their own challenges and would have a hard time financing such a purchase.

UBS analyst Maynard Um speculated on CED that the acquisition of Nortel by Huawei would be a possible outcome giving the Chinese firm a significant increase in market access in North America. However, this scenario may run into trouble with the Committee on Foreign Investment in the U.S. (CFIUS) regulations.
