Samsung Electronics announced the a Galaxy Note 4 S-LTE, the first commercially available LTE Advanced (LTE-A) Tri-Band Carrier Aggregation (CA) smartphone that provides a download peak speed of 300Mbps, four times faster than the speed of today’s 4G LTE service. The LTE-A Tri-Band CA enabled Samsung Galaxy Note 4 is able to select optimally available bandwidths. The device receives three different frequency bands -- 20MHz bandwidth in 1.8GHz band, 10MHz bandwidth in 800MHz band, and 10MHz bandwidth in 2.1GHz band -- and aggregates them into a single connection, supporting Category 6 network service with speeds of up to 300 Mbps. Users can download a 700MB video in about 19 seconds or 10 songs with 40MB in about one second.

The LTE-A Tri-Band CA Galaxy Note 4 is also LTE-A Category 9 service ready, with speeds of up to 450 Mbps download expected to be commercialized later 2015.

SK Telecom plans to offer a tri-band LTE-A service coverage in Korea. In order to provide tri-band LTE-A service, base stations that support three different frequency bands are required. Tri-band LTE-A is offered in areas where coverage of all three component carriers intersect./Tri-band LTE-A is offered in areas where signals from all three frequency bands – i.e. 800MHz, 1.8GHz, 2.1GHz – overlap.
