4G consumer experience better service than 3G

Wireless customers using 4G LTE-enabled devices face lesser data-related issues, than customers who use 3G and other 4G-enabled devices, according to a report by the J.D. Power and Associates.

The study finds that the number of data-related problems, especially those related to slow connection speeds, is lower among customers using 4G LTE-enabled devices than among those using devices with older 3G/4G technology standards, such as WiMAX and HSPA+.

The report suggests that improving network performance, especially for customers using 4G LTE devices, may translate into incremental revenue by not only increasing monthly spending, but also lowering churn rates.

Huawei announces proposal for the LTE-Advanced Multi-Stream Aggregation (MSA) technology standard

Huawei, a leading global information and communications technology (ICT) solutions provider, on Thursday announced a new proposal for the LTE-Advanced Multi-Stream Aggregation (MSA) technology standard that is capable of increasing data rates at the cell's edge.

With the development of mobile broadband, operators are mostly concerned about user experience. With mobile coverage, should able to enjoy the same quality of services no matter where they are. However, with mobile communication systems, the most challenging issue is system performance at the cell's edge.

The concept behind Huawei's MSA technology is that the user is always able to receive downlink data and aggregate downlink data streams from a cell or cell group with the best signal quality. A similar method applies to uplink data, where the user always transmits uplink data to a cell or cell group with the best signal quality. The uplink data streams are aggregated on the network side.

American telecom giant AT&T is planning to shut 2G wireless networks by 2017

While 2G spectrum is creating headache to operators in Indian mobile market,AT&T to shut 2G network in the U.S.

APAC Expected to Lead 4G Market by 2016

Asia Pacific to lead the 4G LTE market by 2016.
The Asia & Pacific region will overtake North America in number of 4G/LTE subscribers.


Asia & Pacific will have more than 53 percent of 4G/LTE subscribers. Globally, the total number of subscribers will be over 560 million by 2016.


"Fifteen carriers in Asia & Pacific now have live LTE services, with affordable pricing models that prompt robust subscriber growth in this region. Mobile operators worldwide have committed to 4G/LTE as the network technology of the future, but financial conditions, handset costs, and spectrum license availability will all influence the pace and scope of regional deployments" said Harry Wang, director, Digital Health and Mobile Product Research, Parks Associates.


According to research global 4G/LTE subscribership will increase from 9 million in 2011 to over 560 million in 2016.

Alcatel-Lucent Announces Loss and Plans to Cut Down 5,000 Jobs

Mobile equipment major Alcatel-Lucent has decided to slash 5,000 jobs.


The telecom equipment maker will restructure unprofitable markets as part of a program to lower costs by 1.25 billion euros ($1.52 billion) by the end of next year.


Alcatel-Lucent will miss its 2012 profit margin target and pre-announced an adjusted operating loss of 40 million euros on sales above 3.5 billion in the second quarter.


The job cuts will affect 6.4 percent of Alcatel-Lucent's 78,000 employees. The group will also seek to get rid of unprofitable services contracts in which it manages networks for operators, squeeze more money out of its patent portfolio, and exit or restructure in countries where it is weak.


Alcatel-Lucent also gave a new annual profit target of posting a second-half adjusted operating margin better than the first half when it stood at minus 3.7 percent. It confirmed its prior target of aiming for a strong positive net cash position at the end of 2012.


Recently, Nokia and RIM announced their plans to cut jobs.


Alcatel-Lucent said sales in its wireless and optic divisions had a double-digit decline in revenue because of moderate spending from service providers. Sales in its software, services and solution segment also declined, and the services business was almost flat, it added.


Revenue in North-America, Europe and the Asia Pacific region witnessed a double-digit decline, the company said, adding that the decline in Asia was mainly driven byChina, where sales fell by 21 percent.



Competitive pricing was one of the main reasons that eroded profitability, the company said. Overall revenue was €3.5 billion, down 7.1 percent year-over-year.
"These times demand firm actions," said Alcatel-Lucent's CEO Ben Verwaayen in a statement. Besides cutting 6.6 percent of its total of 76,000 employees the company also plans to exit and restructure unprofitable markets and is planning to manage its patent portfolio as an independent profit center, it said.

Huawei surpasses Ericsson as world's largest telecom equipment vendor

Huawei is set to retain top telecom equipment vendor position in coming quarters, thanks to its growing revenue from enterprise and mobile phone businesses.


Its main rivals - Ericsson and Nokia Siemens - do not have this big opportunity to compete with the Chinese telecom equipment maker. 



Chinese telecoms giant Huawei Technologies on Tuesday reported a 5.1 percent rise in sales to 102.7 billion yuan (US$16.1 billion) for first-half 2012, ended Jun. 30, which surpassed Ericsson's 106.3 billion kronor (US$15.25 billion) over the same period.



Since 2011, the slowdown in the global market have seen telecom operators worldwide reporting lower income and profits, resulting in even greater competition between telecom equipment manufacturers.


"[Huawei] continues to maintain robust growth momentum, although the global economic situation and telecom equipment market remains a significant challenge," said the company.


The Chinese telco player was "relatively optimistic" about the operating performance and profitability for the remainder of 2012, said its CFO Meng Wanzhou.


According to Ying Weimin, President of Huawei GSM&UMTS&LTE Network, Huawei helped Deutsche Telekom, Telefonica, Telenor, TeliaSonera, and Vodafone launch their LTE services commercially.
