Summary:

Nokia Siemens Networks is ready to take wireless broadband to a whole new level: peak rates of 672 Mbps by 2013 with Long Term HSPA Evolution. T-Mobile is happily backing the effort, since it’s not yet clear what 4G path the carrier will take.

Nokia Siemens Networks Wednesday promoted a new wireless broadband standard that could offer peak downloads speeds of 672 Mbps, or roughly 100 times faster than the average 3G speeds of today. The proposed standard, Long Term HSPA Evolution (LTHE), already has initial backing from T-Mobile USA, a carrier that hasn’t yet decided on its 4G, next-generation plans. Instead, the operator is migrating its network to HSPA+, which currently tops out at 21 Mbps.

To achieve such speeds, which are far beyond what any currently available wireless data networks offer, signals from up to eight different frequencies could be combined to create a single — albeit very fast — data stream. Indeed, a similar solution is used now in DC-HSPA+ or Dual-Channel HSPA+ networks, which combine data from two frequencies and deliver speeds up to 42 Mbps. T-Mobile has previously considered a future speed bump of its network beyond 42 Mbps and would likely use DC-HSPA+ to do so, but if LTHE is approved as a standard, the carrier could step on the accelerator and offer much faster speeds as early as 2013.

Increased download speeds aren’t the only benefit of the new proposed standard, which has approval by the 3GPP, a telecommunications standards body, to proceed with further investigation. LTHE would be backward-compatible with older HSPA and WCDMA devices, making the transition easier for device makers and consumers alike. And, the ability to combine data streams from multiple channels or frequencies can help operators that may not have enough spectrum in a single channel; by using a secondary frequency, there’s less need for a carrier to purchase more spectrum in a particular frequency, for example.

For folks like me who are blown away by 12 Mbps speeds from Verizon’s recent LTE deployment, it’s almost hard to fathom that devices in 2013 could use a wireless network capable of 100 Mbps, let alone nearly seven times that. I wonder if such devices will be larger due to the need for additional antennas to support multiple channels. More important may be the costs and data plans for such speed: At 500 Mbps, for example, a 5 GB monthly data plan could be used up in 82 seconds!

I suppose I’ll have to make do with today’s HSPA+ and LTE networks for a while, because there’s no guarantee the LTHE standard will be approved. For now, this is all in the planning stages and will be researched further within 3GPP work groups.

  2. Interesting but completely non sequitur. It does not follow that even if you can transmit data solo at extremely high rates on unoccupied interference-free frequencies, which is all the demonstrations have shown at this point, that it can be applied to congested urban settings. It’s that old physic’s thing: there’s a fundamental limit of how much information can be pushed through a given volume of space in a given amount of time with a given amount of spectrum independent of the technology employed. 672Mps of peak capacity for one person is 2Mps at best for 336 people; not as an exciting a prospect.

    However, there are some that may be giddy with anticipation: the carriers and phone manufacturers, Both want new acronyms to push product. (A good example is how the ‘4G’ label is being misused.) The carriers alone want new reasons to pressure the government in their public spectrum land grab.

    I’m not against technological innovation, but before I can judge whether not something might be good or not, I need intelligent and reasoned assessments as to who benefits and doesn’t and if real progress is being made. I’m afraid pre-rollout backyard tests of new services and hardware just don’t cut it.
