Lack of standardization to carry the 4G to 450MHz

The verge of the Brazil tender the 450MHz band - which is geared for the inclusionrural and auction is scheduled now for May by the government Dilma - Qualcomm, a maker of chipsets, today announced that in the near future will have multimode chipsto 450MHz. This means that the chipset will work in the range of 3G and 4G. But tostreamline their production ecosystem, 3GPP also needs to standardize the range for the fourth generation of mobile telephony.

In an interview with Digital Convergence Portal, president of Qualcomm Brazil,Rafael Steinhauser, declined to detail terms for the commercial release of thechipset. "In the near future we will have. Most important is that we are showing the evolution of technology for the track. It's a commitment. But we do need, the standardization of 3GPP to 450MHz for 4G," said the executive.

3GPP is an organization dedicated to the standardization of GSM-based technologies. Also according to Steinhauser, the standardization process is alreadyunderway and that the use of LTE in 450 MHz, and expand the supply of services for users, also favor the roaming coverage areas in other frequency bands.

By participating in the Campus Party, the communications minister, PauloBernardo, was critical to the technology adopted in the 450MHz - CDMA 2000,calling it 'outdated', but the president of Qualcomm Brazil ensures that it is equivalent to that used in 3G services .

"Several countries, including Latin America, use the CDMA 2000 to provide services at 450MHz, no ecosystem on the market and the speeds are equivalent to those offered in 3G. There is no technology lagged," said Steinhauser.

"What we do and we are doing is working its evolution. Chipset with 450MHz forLTE is proof that the use of the band is feasible and can indeed attract telecom operators," he concluded.

Bernard criticizes the Oi and ensures that Anatel maintain rules on quality

By participating in the Campus Party, technology event that happens in the state capital, the Communications Minister Paulo Bernardo said that the action of Oi, who requested the removal of the goals of service quality of broadband, is "totally wrong".It also held that the Anatel will not return after what has already been set in October last year, when the rules were published for the service quality.

Paul Bernardo noted that the charge for broadband service quality was a direct demand of President Rousseff, even last year, when discussing the National Broadband Plan.

"The president has a right to determine if sold 1 Mbps or 10 Mbps, should deliver theclosest thing. She demanded minimum standards of quality. It was then that Anatelhas gained muscles went ahead with the editing rules. Quality was a proposedgovernment and remains, "the minister argued.

When talking about the application of Oi - whatever the elimination of rules of quality measurement proposed by Anatel - Paul Bernardo was very hard. "The positioning ofOi was totally wrong." It ensured that the Anatel will not answer the poll. "Are you in the face that the Anatel will not uphold it. Will someone there, and she complains (Anatel)go back? Can not," he added.



Regarding the possibility of going to court Oi, Paul Bernardo was even more emphatic in his criticism"They may even go to courtbut I believe that the magistrates, in good conscience, no one will pay attention to this election, since they themselves complain that the Internet is slow and without quality," he said.

To the Minister of Communications, the imposition of quality goals means rather thatthe telcos will have to invest more in infrastructure to improve the provision ofserviço.Mas recalled that the government is working to make aa his part.

Both promised that, once againthat 'within days', the Measure of relief for fiber optic networks will be brought to the president Rousseff. "Everything is settled with the economic areaWe will reduce taxes and make our part, but the telcos will have toinvest even more, "added Paul Bernardo.

During his presentation at the Campus Party, Paul Bernardo noted that the $ 16.5 billion of foreign investments accounted for by the Central Bank in the country in 2011, the area of ​​Telecom accounted for 35- about $ 6.5 billion.

Police in Sao Paulo charges the Anatel for LTE network in 700 MHz band

With a pilot LTE network in 700 MHz band, in progress for a year and two months, led by Alcatel-Lucent, with the participation of players such as IBM and Microsoft, and manufacturer of mining MXT, which is a supplier of 12 000 tablets used in cars, the Military Police of São Paulo argues that investment in the private network at 700 MHz is not a fight 'policy'. It is a matter of cost / benefit.

"LTE at 700MHz out up to six times cheaper than at 2.5 GHz In addition, I will share my infrastructure for voice services," writes Colonel Alfredo Deak, responsible for the technology of the Military Police of São Paulo. In this Thursday, 26/01, Military Police and Alcatel-Lucent presented the results of the pilot conducted in the metropolitan region of Sao Paulo.

The test authorized by Anatel, involves three base stations LTE, 4G mobile phone, used to transmit data in real time and seen as crucial for applications, including the monitoring of day-to-day, through cameras surveillance.




Quality of service: The differential LTE
"LTE allowed us to give intelligence to the police. The information has to be passed in real time and without human presence," adds Colonel Alfredo Deak. Still according to him, testing the connection speed has reached 60 Mbps LTE and the institution has not yet found a product in the telecom service offerings: Guaranteed quality of service.

"In the 3G you can not have this transmission in real time, with the quality we need and how quickly we want. In LTE, a private network, we can even prioritize our demand. The public network LTE when it comes, will be a contingency. Police is not only the Police to integrate health, surveillance, "Deak holds.

To show the importance of using technology to the military police, Deak posted the numbers: 100 000 are police officers, 17,000 vehicles (12,000 tablets with them already installed), 23 helicopters, two ships and 600 barges. The numbers 190 and 193 meet 180 000 calls per day, coming out of the 645 municipalities in the state covered by the corporation.

In the pilot project, the investment was around U.S. $ 2 million. The cost of a commercial service is budgeted at 700 MHz, about $ 100 million in the metropolitan region of Sao Paulo. "I do not want to enter the political fray of the band 700 MHz I see the practical side of public safety," insisted Colonel Deak. "Doing our private network that will reduce the range by up to six times the cost, if the band were to be used 2.5 Ghz. And we all know that money that we use is public," he added.



"Besides, we also want to raise our voice service. Today we have 60 and VHF channels available.'s Very little to our day-to-day. Today, in 1000 police officers, only 60 can speak. We need to talk to the radio the cop who is out of the car. we are moving to UHF, which will allow us to get to 360 channels. And we can, yes, use the existing infrastructure to put the RBS of LTE, "insists Colonel AM of St. Paul.

Officially, the Military Police of Sao Paulo asked the Anatel to release a range of 10 MHz + 10 MHz to make your private network LTE. Other MPs, among them the Federal District and the Army itself, has also requested the use of the band, but so far, the agency has not stood up because it works in the release of the 2.5 GHz band The digital dividend in the 700 MHz band is complex because it involves a dispute between broadcasters and telcos.

"We really want a decision by the Anatel later this year. We are ready to make a commercial network. The pilot has proven consistent. The technology does what is asked of her. But no spectrum is not possible," said Deak. Responsible for technology, Alcatel-Lucent argues that the pilot conducted at 700 MHz at 2.5 GHz is feasible, but assumes that there are indeed a matter of cost to be placed.

"2.5 GHz requires much more equipment. In the United States, the projects were for the public safety 700 MHz band by cost," says the president of Alcatel-Lucent, Ionian Foigel. The pilot of the Military Police of São Paulo is the first in the area of ​​public safety, using LTE in Latin America. According Foigel within Alcatel, he is among the five made ​​by the manufacturer in the world.
