Samsung has unveiled a new version of its Galaxy Note 4, featuring support for LTE Advanced Tri-Band Carrier Aggregation and Category 9 cellular networks.
Dubbed Galaxy Note 4 LTE-A, it promises much faster download speeds over 4G LTE compared to the regular models, which the South Korean maker announced in early-September.
Galaxy Note 4 LTE-A is capable of offering download speeds of up to 450 Mbps.
To put things into perspective, that is 50 per cent faster than the Qualcomm Snapdragon 805-equipped Galaxy Note 4 - which is no slouch to begin with - and a whopping 200 percent faster than the Exynos-powered model.
However, Galaxy Note 4 LTE-A will only be able to reach those kind of download speeds later in 2015, when 4G LTE Category 9 cellular networks are expected to be commercially available.
That being said, the phablet does have another trick up its sleeve, which it will be able to use much sooner.
Because it features LTE-A Tri-Band Carrier Aggregation, Galaxy Note 4 LTE-A can connect to three cellular network bands at the same time, and, as the name of the technology implies, aggregate them into one, juiced-up connection.
Compared to the Snapdragon 805-powered Galaxy Note 4 - which can only connect to up to two bands simultaneously - the new model is better equipped to maximise the transfer speeds offered by today's fastest 4G LTE cellular networks, which enable download speeds of up to 300 Mbps.
One thing that Samsung is not clear on is which processor powers the new Galaxy Note 4 LTE-A. Is it still Snapdragon 805, or has Qualcomm supplied its newer Snapdragon 810? Given Samsung's track record, I'm inclined to believe it is the latter.
There is no official word yet regarding where Galaxy Note 4 LTE-A will be available, and how much it will cost when it goes on sale.
