ZTE achieves HSUPA upload rates of 15.2 Mbps. Do we really care?

ZTE has broken a record today. No, it’s not in smartphone sales or anything like that. It has to do with HSUPA upload speeds. The Chinese company has conducted a test in which it managed to obtain 15.2 Mbps uploads via HSPA tech.

That’s more than the previous record of 12 Mbps. Nowdays, most devices today support a theoretical maximum of 5.76 Mbps for uploads. ZTE claims that carriers around the world can use their solution (which comprises of interference cancellation technology, multi-antenna independent scheduling technology, and four antennae receiving technology) without the need to upgrade the terminals.

The question, though, is whether anyone really cares. Let me explain.

Yes, upload speeds have always severely lagged behind download speeds in the mobile world. After all, the advertised speeds in any contract are always the download speeds. And while those are important too (and arguably still more so than upload speeds), with the advent of social media and constant sharing and smartphones which enable that constant sharing… more and more people are feeling the limitations of current upload speeds.

However, with most of the carriers in the ‘Western’ world now considering LTE deployments, the question remains. Will anyone really care about this? Will you ever get such upload speeds from your carrier of choice?

ZTE obviously hopes so, since for that to happen that carrier needs to become its customer. But realistically, this development is a bit late to the party. Two years ago, it would have been all the rage. Now though, all we can think about is LTE. Yes, LTE won’t make it to some parts of Europe, for example, for at least another year, and deployments will be limited at first (all new mobile tech suffers from this gradual rollout). But incorporating ZTE’s new upload tech over HSPA will surely take a few months as well, so it’s doubtful that any carrier that has an LTE roadmap will bother investing in HSPA to this extent anymore.

    This technique does not increase an individual user’s peak data rate, which at Cat6 always remains at 5.76Mbps, it increases the total UL sector throughput. An individual user would not notice any difference
