15 exciting tech shown at MWC 2015

Google's Project Ara phone comes to MWC

We haven't heard much about Google's Project Ara since last year. Is it still going on? Will Google's Project Ara—Lego-like smartphone concept—really take off?

It turns out that it's alive and well.

We sighted at least one Project Ara-based phone in Marvell's meeting room at the Mobile World Congress. It was housed in a glass case.

Marvell is apparently getting ready for an Ara module, bringing its apps processor knowledge and expertise to Google's project.

Marvell claimed that Google has selected Marvell's quadcore 64bit 5-mode 4G LTE ARMADA Mobile PXA 1928 solution for its Project Ara platform.

LTE-U controversy looming

Qualcomm unveiled LTE-Unlicensed (LTE-U), designed to extend LTE Advanced to unlicensed 5GHz spectrum for higher capacity and coverage.


It's gotten a lot of buzz, especially at Qualcomm's booth (shown above).

Qualcomm's CTO claims the new spec comes with an additional "co-existence" mechanism so that "even a single Wi-Fi user surrounded by LTE-U users will actually perform better than surrounded by other Wi-Fi users."

But astute engineers and consumers are already smelling danger. It's good for cellular vendors, but what about consumers who are so used to using Wi-Fi in hot spots?

What LTE-U is doing to Wi-Fi is a telltale sign of what 5G would end up doing to Wi-Fi.

It is unclear what 5G will do to Wi-Fi. Will it start crowding out this space once it begins to encroach? How will it affect on the massive number of Wi-Fi services now available around the world? Will unlicensed spectrum become licensed?

Huawei to conquer 'Internet of vehicles'

Aside from telecom equipment used in network infrastructure, servers and handsets, Huawei is keen on getting into automotive.

Internet of vehicles

We came across a team of young Huawei engineers demonstrating V2X technologies in the Vodafone booth.

One example the company showed off was what Huawei calls the "car router" of the future. When you're driving behind a large truck, "you'd like to see what's going on in front of the truck, wouldn't you?" asked Mohamed Ibrahim, senior research engineer, Huawei's European Research Center, Internet of the Vehicles, located in Munich. Using a secure V2V connection with very low latency, the truck can stream video (its front view) to the car behind, he explained.

It's still an R&D project, and it may not be even realistic. But it helps people visualise what they could expect in the V2V world, Ibrahim said.

More remarkable is Huawei's commitment to R&D in the Internet of Vehicles.

The Chinese behemoth started out with 100 researchers in Munich only a few years ago. The team has quickly grown to 350, he explained.
