How about that: A 100 Mbps mobile hotspot

Huawei has packed a lot of speed into its latest mobile hotspot. The rather awkwardly named E589 FDD is intended to push the limits of current LTE technologies, offering peak speeds of 100 Mbps, which it can redistribute to as many as 10 Wi-Fi devices. The catch is that the hotspot is only available in Japan, because that’s where the only network resides that can support it.

In January, I wrote about eAccess building the mother of LTE networks, and this month it’s set to launch. By maximizing the technical standards of LTE to the hilt, eAccess is building a network that can support theoretical capacities of 300 Mbps, so while Huawei’s device is impressive, it’s not even taking advantage of the network capabilities. I should be able to support the peak speeds eAccess is advertising to its customers, 75 Mbps – not too shabby considering U.S. LTE networks top out at about 25 Mbps.

It will be a while before U.S. networks can support such eye-popping speeds – U.S. operators don’t have such large contiguous spectrum blocks – but that’s probably a good thing. At today’s mobile data pricing, consumers could eat up their monthly gigabyte allocations within days, if not hours, especially if they’re connecting multiple devices to a hotspot.

      Hi Lora,

      A lay out some of the details in my post from January, but essentially a lot of spectrum, complex modulation and a bunch of antennas. Though the Huawei device doesn’t appear to use all of those.

    Kevin, all current LTE MiFi’s sold in the U.S. and worldwide (beside motorola’s) are Category 3 UE, and capable of 100mbps down and 50mbps up. That’s of course limited by 10Mhz physical layer to 73.6mbps. In Scandinavian countries where their providers have 20Mhz channels, you’ll often see 100mbps UE maxing out at about 98mbps. Impressive nonetheless.

      Hi Milan,

      You’re right. I forgot about the TeliaSonera and other Nordics using 20×20 carriers. We’re going to see a lot more of that in Europe — they’re getting some big spectrum chunks, right?

      Any thoughts on why Huawei didn’t push for Category 4? The way Apple and T-Mobile are talking the technology seems to be available.

        Rel.8 Cat 4 isn’t available at the moment, with Qualcomm releasing first UE in Q2 2013, and Renesas actually starts sampling it Q3 this year. Cat 4 chip would completely open up that 150mbps 2x20Mhz channel.
        Also, keep in mind that when we are talking about LTE 73.6mbps peak, those are the real world speeds after the overhead. In other legacy technologies like 42mbps HSPA+, we are talking of maximum theoretical speeds. Real world speeds are noticeably lower, usually around 30mbps.
