Audit Report.Mobile Benchmark Brazil, 2019

Forewörd.

With a gross domestic product of 1.9 billion dollars in 2018, Brazil is the nineth largest economy worldwide. Regarding land area and population, ­Brazil­is­the­fifth­largest­country­in­the­world. And with approximately 208 million people, Brazil is the most popoulos country in South America. After­a­recession­in­2015­and­2016,­ Brazil‘s economy is growing again.

All these factors are very good reasons for umlaut to take a closer look into the Brazilian mobile communications market. umlaut, head-quartered in Aachen, Germany, is a world leader in mobile network testing. The company has over 4,100 employees world wide and­a­­turnover­of­­more­than­350­mil­lion­Euros.

For the most recent crowdsourcing analysis conducted in

Brazil,­1.8­million­users­have­contributed­15.5­billion­sam-

ples. The evaluation area of our crowdsourcing represents

99.6­per­cent­of­the­built-­up­area­of­the­country.­

With­an­area­of­8.5­million­square­kilometres,­Brazil­is­the­

fifth­largest­country­in­the­world,­accounting­for­more­than­

47 per cent of the surface of South America. It is no sur-

prise that this unique geography means huge challenges

for mobile Operators and makes it very hard to provide

countrywide network coverage. As about 90 per cent of

the Brazilian population are located in the federal States

near the southern and eastern coast of the country, ob-

viously mobile network operators focus on servicing these

areas – especially the larger cities. These prerequisites are

also­reflected­in­testing­and­benchmarking­the­perfor-

mance and coverage of mobile networks. For the reasons

mentioned, approaches such as classic drivetesting can

only consider more densely populated areas. In contrast,

the method of crowdsourcing is ideally suited to analyze

the actual characteristics of the Brazilian mobile networks.

These analysis are based on gathering information in the

background­while­smartphone­owners­use­a­set­of­specific­

apps. However, the most important aspect is that this

of the built-up area of Brazil – which makes it statistically

Overview.Crowdsourcing based test data

Telefónica scores highest in Voice and Data.The coverage values determined for voice and data rate

the areas where the according services are available.

However,­it­must­be­taken­into­account­that­the­specified­

percentage­values­do­not­reflect­the­respective­parts­of­

Brazil‘s land area, but the quota of points that an operator

can achieve in this discipline. These points are earned for

both the actual coverage and also the “Quality of Co-

verage“ – a value representing whether voice and data

services actually work in the conside-red evaluation area.

In both disciplines, Vivo scores still higher than its compe-

titors. But the gap is much wider in the data category than

in the voice category, where all four Brazilian operators rank

closely together.

TIM gathers highest number of points for 4G Co-verage.When assessing the coverage of 4G service, TIM is ahead

of its competitors. Vivo and Claro still achieve remarkable

results, while Oi ranks clearly behind.

Claro ahead of competition in User Download Speed.The crowdsourcing also assesses the data rates that users

actually achieve when utilizing their smartphones. In this

examination,­Claro­is­leading­the­field,­Vivo­still­achieve­a­

again, Oi ranks last in this discipline.

Telefónica and Oi leading in Data Service Availa-bility. This KPI rates the number and length of service degrada-

tions within the observation period. Between January 2019

and June 2019, Telefónica and Oi achieved the highest
