Sprint Corp has demonstrated downlink transmission speeds of more than 300Mbps using the Samsung Galaxy S7, which it says is one of the first devices on the market with hardware capable of supporting three-channel carrier aggregation (CA). Sprint currently uses two-channel CA – equivalent to 40MHz of spectrum on select 2.5GHz cell sites – to deliver peak speeds of more than 100Mbps in more than 150 ‘LTE Plus’ markets across the country. Three channel CA will see Sprint utilise 60MHz of bonded spectrum to create wider channels and produce more capacity and faster speeds.
Sprint CTO Dr John Saw commented: ‘Our high-band 2.5GHz spectrum excels at moving high volumes of data at very fast speeds. And while 60MHz of spectrum can deliver the kind of phenomenal speeds shown today, we’re just getting started. With holdings of more than 160MHz of 2.5GHz spectrum in the top 100 US markets, we have more capacity than any other carrier in the US. This is a tremendous advantage, allowing us to keep adding the capacity and speed needed to serve our customers’ demand for data now and well into the future’.
