Nokia’s(s nok) network division is returning to work at Sprint(s s) after a multiple-year hiatus, and it apparently wants to make a good impression. Nokia announced it has used its Flexi base station gear to transmit an eye-popping 2.6 Gbps downlink connection on Sprint’s Spark LTE network, breaking Sprint’s previous record of 1.6 Gbps.
Nokia was able to accomplish this feat by tapping into Sprint’s enormous treasure trove of 2.5 GHz spectrum. Using LTE-Advanced carrier aggregation techniques, Nokia and Sprint bonded together 120 MHz of frequencies, giving it six times the bandwidth of most LTE networks deployed in the U.S. today.
In addition, Nokia likely took advantage of the unique properties of the LTE technology variant Sprint uses in Spark. Time division-LTE uses the same frequencies to transmit to and from the tower – it just sends the uplink and downlink in different time intervals. Most other…
