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communications minister, PauloBernardo, was critical to the technology adopted in the 450MHz - CDMA 2000,calling it 'outdated', but the president of Qualcomm Brazil ensures that it is equivalent to that used in 3G services .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

4G in Brazil: Operators persist in separate 450 MHz from 2.5 GHz

In a public hearing held on Tuesday, 31/01, in Brasilia, Anatel, the SindiTelebrasil defended the decoupling of the bands 2.5 GHz and 450MHz in the auction for the sale of spectrum, scheduled to take place in April by Dilma. Also stated that goal setting 4G service coverage occur only for the host cities and sub-offices of the Confederations Cup and 2014 World Cup.

The position places telcos and again Anatel in opposing camps. The FCC linked the tracks on the grounds of attracting interested in buying the 450 Mhz band, aimed to bring telephony services and broadband to rural areas. For SindiTelebrasil, however, bands of 450 MHz and 2.5 GHz 'features and have different purposes. "

In his presentation, made ​​it clear that aa SindiTelebrasil technology available for use in sub-450 MHz band is not indicated for the Brazilian case, because there is no synergy with other technologies in operation. Also according to the entity, "this track has less capacity for data transmission, low production scale and uncertain progress."

Now with respect to the use of 2.5 GHz, for their technical and functional characteristics, the range is ideal to meet the needs of data capacity, not coverage, still held Sinditelebrasil. The operators made ​​it clear that "the coverage targets set out in the announcement, for the use of 2.5 GHz, require high levels of new investments to be made ​​that have occurred without the amortization of the investments made for the service of the notice of 3G ".

Anatel works with prediction that all host cities Confederations Cup 2013 will be served by the end of May 2013 with the 4G technology. Also claims that by the end of that year, all branch offices and headquarters of the World Cup 2014 will be achieved. For the capitals and cities with over 500,000 inhabitants, the fourth generation of mobile phones should arrive by May 2014, while cities with more than 100,000 residents are expected to benefit up to December 2015.

Finally, in addition to charge using the 700 MHz band for 4G - this band is caused by the scanning divididendo digital TV by using the SBTVD - the SindiTelebrasil stressed the need for mechanisms to be established for coverage and service areas rural and remote areas, with public funds, especially the telecommunications sector funds.

The public consultation on the draft bidding documents for the issuance of permits use of the Radio sub-band 2.5 GHz and 450 MHz, associated with exploration permits for Multimedia Communication Service (SCM), the Fixed Switched Telephone Service Aimed at use of the General Public (STFC) and and the Personal Mobile Service (SMP), available through the Public Consultation No. 4, was opened on January 25 and will receive contributions until February 26
