Globe Telecom has deployed massive multiple input, multiple output (MIMO) technology to expand its network coverage and capacities so as to improve mobile and wireless broadband services in crowded areas.
The massive MIMO enables a mobile network to multiply wireless connection capacity without adding antennas, thereby increasing wireless throughput that could accommodate more users at higher data rates, Joel Agustin, senior vice president for Programme Governance, Network Technical Group of Globe, explained.
Globe tested the massive MIMO in Makati financial district early this year before rolling it out to its 150 wireless broadband sites, located mostly in Northern and Southern Luzon. The telco said initial test results showed that the technology has expanded its network capacity by six times more than the regular site.
The massive MIMO uses the additional 2600 MHz that Globe gained from partial acquisition of San Miguel Corporation's telecommunication assets last year.
It was activated using 2CC carrier aggregation technology, which uses two separate blocks of 2600 MHz spectrums that are aggregated through LTE-A. To put it simply, Agustin said the 2CC technology is like increasing the number of lanes in a highway from one to two, which makes internet speed faster.
"The use of massive MIMO technology is an important component of our goal to stay ahead of the demand curve for data capacity in densely populated and high-foot traffic areas," said Agustin.
