TIM Brazil will have carrier aggregation, WiFi Calling, ViLTE and VoLTE

Huawei was the supplier chosen by TIM Brazil to deploy new technologies.

TIM is expanding its 3G and 4G network infrastructure in Rio de Janeiro. TIM will also use the occasion to test new services on living network, as WiFi Calling, VoLTE and ViLTE (video call for LTE) with selected users. The 4G is the big bet. It is expected that, with the presence of tourists and thanks to the high purchasing power of whom will attend the event, 70% of the data traffic will transit in 4G.

For the event, TIM will increase by 47% the amount of 4G sites that will be 1,137 sites. By the end of the year, more will be added, for a total of 1300, among which 76 will be temporary.

The 3G was also remembered. The company is expanding 14% of the amount of 3G sites, that is, 1,003 sites will be added, of which 61 will be temporary. The others will be legacy. By the end of the year, the company promises to have more than 1200 3G sites in the city.

The metropolitan area also has backup. Leonardo Capdeville, CTO of the company, says that TIM will expand in 53% 4G sites in cities around the capital, and in 30% the 3G.

With the investment, Rio de Janeiro became the city with greater coverage of the operator in the country, edging out Sao Paulo. "We are also investing in São Paulo, which by the end of the year will return to have more sites," he explains.

Technologies

Huawei was the vendor chosen to implement the expansion of the network who is installing capable sites of carrier aggregation and technology C-RAN, software control of the ERBs. TIM will use 1.8 GHz bands and 2.6 GHz, adding 10 MHz of each track.

Huawei also delivered a key event project assurance – a system of monitoring and measurement of network usage able to correct faults or overloads in real time which will equip the existing headquarters of TIM.

In the stadiums, TIM enters the network infrastructure sharing, which uses the active architecture and carrier aggregation. At airports, the copartilha and Porto Maravilha, TIM deployed 40 3G and 4G small cells. In addition, TIM strengthened the coverage on the routes that lead to the sites of the event.

To be able to test the services of WiFi Calling, VoLTE and ViLTE, TIM updated the network architecture for IMS technology. "With this architecture we're already prepared to add future services to enrich the user experience, expanding coverage and offering more spectral efficiency," says Capdeville.

He did not say when these three technologies will be released to the end user. To happen, the commercial offer of the services they need, first, pass the test and, second, be defined. The operator doesn't know yet what the best business model: charge per call, taking it out of the franchise, or the franchise of data.

Roaming

TIM wants to attract the most foreign travelers to their network. So, TIM expanded the amount of international agreements that it has with outside carriers. In 3G, it has a contract with 345 operators of 160 countries. In 4G, it tripled the number of interconnections which will accept 60 cellular operators of 30 countries.
