NTT DoCoMo Achieves "Super 3G" 250 Mbps Downlink

NTT DoCoMo has demonstrated a downlink transmission rate of 250 Mbps

over a high-speed wireless network in an outdoor test of an experimental Super 3G system for mobile communications. The "Super 3G" system trial has been underway using an actual wireless environment near its R&D labs in Yokosuka, just south of Tokyo, since February. The test involves four Multiple-Input Multiple-Output (MIMO) antennas for base-station transmission and mobile-station reception in the 20MHz bandwidth, the maximum under new Super 3G standards.


DoCoMo said it is continuing to test connection handover from one base station to another, and the functionality of applications in indoor and outdoor environments.


Super 3G, which features low-latency data transmission and high spectrum efficiency, is an evolution beyond the High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA) protocols of W-CDMA, an original technology for 3G packet transmissions. Super 3G, also known as Long Term Evolution (LTE), is being standardized by the 3rd Generation Partnership Project (3GPP) and core specifications have been approved already.

  • In September 2007, NTT DoCoMo announced a milestone of the way to "Super 3G" wireless, also known as Long Term Evolution (LTE) in the 3rd Generation Partnership Project (3GPP) -- the company has developed and successfully tested a trial large-scale-integration (LSI) chip incorporating advanced power-saving signal-processing technologies that enable the chip to work at a sufficiently low power consumption and to be made small enough to fit into forthcoming Super 3G handsets and beyond.


    DoCoMo reports that its LSI achieved a transmission rate of 200Mbps with high precision over a high-speed wireless network, while power consumption did not exceed 0.1W thanks to its proprietary signal-processing technology.


    The company said its LSI demodulates and separates MIMO (multiple-input multiple-output)-multiplexed OFDM (orthogonal frequency division multiplexing) signals transmitted in the 20MHz bandwidth from four antennas. Signal processing is based on MLD (maximum likelihood detection) technology that DoCoMo has originally developed for 4G wireless access. Redundant circuits have been eliminated in the experimental chip, which was made with 65 nanometer processing.


    DoCoMo plans to continue to develop Super 3G and 4G technologies in combination with its LSI technology, as well as cooperate in the establishment of related international standards.

mimoOn GmbH Demos 3GPP LTE on Software Defined Radio Platforms

mimoOn GmbH announced the implementation of an end-to-end LTE software solution. The company said its platforms offer the high processing power required for LTE, but instead of using high clock frequencies, use parallel processing technology in order to keep power consumption low. The software solution also offers key features such as reconfigurability, which is key for supporting legacy mobile standards such as 3G and 2G whilst LTE evolves. The mimoOn SDR LTE platform supports the optional features of LTE, and it is future-proof and scalable to meet the processing requirements of future releases such as Advanced LTE and MIMO in the uplink.


mimoOn offers two versions of its SDR LTE product: one customized for base stations, picocells, and femtocells; and the other for client devices such as data cards, mobile phones, wireless modules and wireless modems. http://www.mimoOn.de

BigBand Selected by China's Zhongshan Cable

China's Zhongshan Cable is deploying BigBand Networks' Broadband Multimedia-Service Router (BMR) to process, manage and deliver digital television services, including HDTV and video-on-demand (VOD). Zhongshan Cable serves approximately 300,000 subscribers in the city of the same name, among the larger urban centers in China's Guangdong Province. Financial terms were not disclosed.


Zhongshan Cable is using the BMR as a digital "headend-in-a-box." BigBand's "RateShaping" capability leverages advanced algorithms to allow Zhongshan to increase the amount of standard and high-definition digital video that can be delivered over its cable network without using additional bandwidth. The BMR also performs quadrature amplitude modulation (QAM), scrambling and acquisition functions to allow video content acquired from satellites to be delivered over Zhongshan's network.http://www.bigbandnet.com

Lockheed Martin Announces Milestone for Navy's Next-Gen Satellite

Lockheed Martin announced a key milestone in the development of the Mobile User Objective System (MUOS)

with the successful completion of static loads testing of the first satellite in the program constellation. MUOS is a next-generation narrowband tactical satellite communications system. The new satellites, which will deliver simultaneous voice, data and video in real time to mobile terminals around the globe, will replace the current narrowband tactical satellite communications system known as the Ultra High Frequency Follow-On (UFO) system.


Lockheed Martin said the test validated the satellite's strength and ability to sustain its launch weight of over 13,000 pounds, proving that the structure can carry the physical loads it will experience during the satellite's manufacturing, launch and operation in geosynchronous orbit.


MUOS satellites will be the largest of Lockheed Martin's flight-proven A2100 spacecraft series. The first MUOS satellite along with the associated ground system are scheduled for on-orbit hand over to the Navy in 2010.


Lockheed Martin Space Systems serves as prime contractor and systems engineering lead for the MUOS program. The company is under contract to design, build and deploy the first two MUOS satellites and the associated MUOS ground system.http://www.lockheedmartin.com

Motorola to Split into Two in 2009

Motorola announced plans to split into two independent, publicly-traded companies in 2009. The split would occur as follows:

The Mobile Devices business will continue to supply multi-mode, multi-band communications products and technologies. The business designs, manufactures and sells mobile handsets and accessories globally with integrated software solution. It also licenses a portfolio of intellectual property. Motorola is currently searching for a new CEO for this business.


The Broadband & Mobility Solutions business includes Motorola's Enterprise Mobility, Government and Public Safety, and Home and Networks businesses. These businesses manufacture, design, integrate, and service voice and data communication solutions and wireless broadband networks for enterprises and government and public safety customers worldwide. These businesses also provide end-to-end digital and IP video solutions, cellular and high speed broadband network infrastructure, cable set-top receivers, and associated customer premise equipment for residential and commercial wireless network system access.http://www.motorola.com
  • Earlier this month, Motorola announced the resignation of Stu Reed, president of its Mobile Devices business, effective immediately.




  • On January 31, Motorola confirmed that it is exploring strategic alternatives for its Mobile Devices business. Motorola said at that time that its alternatives may include the separation of Mobile Devices from its other businesses in order to permit each business to grow and better serve its customers.

  • Also in January, Motorola reported Q4 2007 sales of $9.65 billion and net earnings of $0.04 per share, which include $0.05 per share from continuing operations and a net loss of $0.01 per share from discontinued operations. The company said its Mobile Devices business remains challenged, with sales declining 38 percent versus prior-year quarter, while its Home & Networks Mobility and Enterprise Mobility Solutions business continued to deliver strong results.

    Motorola Demos CDMA/EV-DO Rev-A to LTE Handoffs

    Motorola announced the first successful packet-switched network handoff between CDMA EV-DO Rev-A and Long Term Evolution (LTE) technologies in a demonstration with VoIP calls and streaming video. In the Motorola demonstration, laptops and mobile devices are equipped with dual radio transceivers that support both CDMA/EV-DO Rev-A and LTE and are active during the packet handoffs. As a device loses LTE connectivity, it automatically switches to EV-DO to ensure consistent streaming without dropping IP packets. The process is then reversed, and devices switch back to LTE when LTE connectivity is restored. Motorola noted that the handover mechanisms employed in this demonstration leverage concepts which are part of the non-optimized handover procedures in LTE core network SAE standard 3GPP TS 23.402.


    Motorola said its handoff technique illustrates how service providers using CDMA-based networks can smoothly integrate broadband OFDMA and IP packet-based wireless broadband technologies like LTE into their network.

    Verizon Lobbies for Faster Disconnects from Cable TV

    Verizon has asked the FCC to require the cable industry to make it as easy for consumers to choose a new video provider as it already is for them to switch voice providers. Verizon argues that the currently many cable companies refuse to accept video service cancellations from a new provider, creating extra work and confusion for consumers. However, long-established procedures enable a new provider to submit a voice disconnection order on behalf of the customer.


    "The process to switch video providers is more cumbersome for consumers," Verizon wrote in a petition filed with the FCC today to request a declaratory ruling. "Cable incumbents do not accept disconnect orders from the new provider; instead, they require the customer to contact them directly to cancel service after choosing a new video provider and to return equipment.


    In a separate filing with the FCC earlier this week, Verizon said that the cable industry delays its customers' switches to competing voice providers by regularly failing to meet the commission's timing requirements for local number portability.
