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.
