Polkomtel and Ericsson carried out joint tests of aggregation of three spectrum bandwidths in the LTE-Advanced standard and obtained a download speed of as much as 450 Mbps. It was possible thanks to simultaneous use of three 20 MHz carrier frequency slots from 800 MHz, 1800 MHz and 2600 MHz bandwidths. Ericsson software, enabling the aggregation of frequency blocks of up to 60 MHz, was used during the tests.
LTE-Advanced Carrier Aggregation technology enables not only increased maximum download data rates but it also increases the capacity of the LTE network, thus ensuring access to broadband services for a larger group of users. The tests confirmed that the LTE-Advanced standard, together with Carrier Aggregation, could offer a real alternative to fixed-line links.
