Optus Launches LTE TDD Advanced Carrier Aggregation with Huawei

Optus launched Carrier Aggregation (CA) technology on its live commercial LTE TDD (Long Term Evolution Time-Division) network  in Australia.

The deployment, which was carried out in partnership with Huawei, combines two 20MHz carriers on Optus' 2300 MHz 4G Plus spectrum. Initial tests have already shown speeds of above 160 Mbps on a single device.  The live deployment has been rolled out across a number Optus' "4G Plus" sites in Melbourne, and follows an earlier trial of CA and other advanced technologies which saw speeds hit over 500 Mbps on LTE TDD.

"Carrier Aggregation is an LTE-Advanced technology which combines multiple spectrum bands – it's the technological equivalent adding extra lanes to a highway, allowing for higher-speed data traffic," said Huawei Australia CTO Peter Rossi. "This project adds to Huawei's long list of world-first technology breakthroughs. By combining two or more channels or ‘carriers' on existing live commercial LTE spectrum bands, Optus can dramatically increase throughput on its mobile data network."

Additional CA tests have been conducted by Huawei and Optus in St Marys, west of Sydney, combining four 20MHz carriers for a total of 80MHz on the 2300MHz band to deliver mobile broadband speeds of over 520 Mbps.

The same trial also demonstrated a number of additional LTE technologies including:


  • 4×4 MIMO (multi-input-multi-output), which delivered 125 Mbps speeds on a single 20MHz carrier
  • Beamforming, where the network intelligently forms radio signals to deliver the best experience to users as they move around a cell coverage area. Beamforming tests showed a 67% improvement in data speeds at the edge of a cell, from 18 Mbps to 30 Mbps.
  • Circuit-Switched (CS) Fallback, which allows Packet-Switched LTE 4G connections to revert to CS GSM/UMTS 3G networks for voice calls

Huawei expects to launch mobile broadband devices compatible with CA (known as Cat-6 TD-LTE) in 2014.

Huawei Cites 53 Customers for its 400G Core Router

As of the beginning of 2014, Huawei claims that 53 operators worldwide have deployed its 400G core router over the past five months.

Huawei NE5000E boasts a capacity of up to 2 Tbps per slot, 6.4 Tbps per chassis, and 32 Tbps per system.

  • In August 2013, Huawei deployed a 400G IP backbone network for Mobily in Saudi Arabia, and upgraded IP backbone networks for True and DTAC in Thailand.
  • In October 2013, Russian operator MegaFon and Huawei rolled out Europe's first 400G backbone network.
  • In November 2013, Spain’s fixed network operator Jazztel took the lead in deploying Huawei's 400G solution in Western Europe. 


AT&T Ups the Mobile Price War with Incentives for T-Mobile Customers

AT&T launched a limited-time offer to pay T-Mobile customers up to $450 per line when they switch to its network and trade in an eligible smartphone.  The deal provides up to $250 for the trade-in of a recent model smartphone and subsequent purchase of a new smartphone from AT&T at full retail price, plus $200 per line migrated from T-Mobile to AT&T.

  • T-Mobile has announced a press event for the upcoming CES 2014 in Las Vegas, where it is expected to launch its own package of incentives for customers who switch from AT&T.


FireEye Acquires Mandiant for $1 Billion

FireEye acquired privately held Mandiant in a transaction valued at around $1 billion.  The deal consists of
21.5 million newly issued shares (NASDAQ: FEYE), options to purchase shares of FireEye stock, and approximately $106.5 million of net cash to the former Mandiant security holders.

Mandiant is a leading provider of advanced endpoint security products and security incident response management solutions. It has more than two million endpoints installed globally. The solution is designed to tell a company when it has been compromised and what the material impact of the breach is. The company was founded in 2004 by Kevin Mandiant and is based in Washington, D.C..

The acquisition, which recognizes the ever-increasing intensity of cyber attacks and follows nearly two years of collaboration, creates the industry’s leading advanced threat protection vendor with the ability to find and stop attacks at every stage of the attack life cycle. The transaction closed on December 30, 2013.

The combination of FireEye and Mandiant brings together two highly complementary companies, each a recognized leader and innovator in security, and creates an organization uniquely qualified to meet organizations’ needs for real-time detection, contextual threat intelligence, and rapid incident response.

FireEye offers a purpose-built, virtual machine-based Multi-Vector Virtual Execution (MVX) engine that conducts signature-less analysis atop a patented, virtualization technology purpose-built for security. The MVX engine is designed to provide scalable, accurate, and timely protection across the primary threat vectors - Web, email, file, and mobile.. FireEye now has more than two million virtual machines deployed worldwide, providing real-time, dynamic threat protection to more than 1,500 government, enterprise, and small and mid-sized customers.

Mandiant’s endpoint products are already integrated with the FireEye platform.  The companies have been collaborating for 2 years.

FireEye said the combined organization unifies the critical components required to provide state-of-the-art cyber security: the most complete library of actionable threat intelligence on advanced threats and a product suite that can apply that intelligence to detect and prevent attacks on both the network and on endpoints.

“Organizations today are faced with knitting together a patchwork of point products and services to protect their assets from advanced threats,” said David DeWalt, chairman of the board and chief executive officer of FireEye. “Together, the size and global reach of FireEye and Mandiant will enable us to innovate faster, create a more comprehensive solution, and deliver it to organizations around the world at a pace that is unmatched by other security vendors.”

In February 2013, A highly publicized report from Mandiant, a security consulting firm based in Arlington, Virginia, linked cyber attacks on over 140 U.S. corporations to a specific unit of China's People's Liberation Army.


The report, called "APT1: Exposing One of China’s Cyber Espionage Units," details how it has the PLA's Unit 61398 systematically carried out spear-phishing attacks and stole confidential data from leading companies across multiple industries.  Mandiant claims the widespread attacks are on-going.  

In addition to describing the methodology of the attacks, the Mandiant report provides domain names, MD5 hashes of malware and X.509 encryption certificates associated with the attackers.

Some highlights of the widely-cited Mandiant report:
  • APT1 has systematically stolen hundreds of terabytes of data
  • APT1 is believed to have dozens, if not hundreds of human operators.
  • APT1 maintains an extensive infrastructure of computer systems around the world.
  • In over 97% of the 1,905 times Mandiant observed APT1 intruders connecting to their attack infrastructure, APT1 used IP addresses registered in Shanghai and systems set to use the Simplified Chinese language.
  • Mandiant observed APT1 establish a minimum of 937 Command and Control (C2) servers hosted on 849 distinct IP addresses in 13 countries. The majority of these 849 unique IP addresses were 
  • registered to organizations in China (709), followed by the U.S. (109).
