Demoing improvements to mobile phone networks is difficult. Where an individual vendor such as Intel or AMD can show off an improved CPU architecture mostly by themselves, it takes a lot of cooperation between companies to show off advanced mobile data initiatives.
This is just what Sprint, Qualcomm, and Motorola teamed up to do last week at the Smoothie King Center in New Orleans, Louisiana.
The first part of the story revolves around Sprint’s unique placement in the US mobile network market. While network operators such as Verizon, ATT, and T-Mobile in the US currently operate their LTE networks on low and mid-band LTE frequencies, the vast majority of Sprint's allocated frequency into the high-band range of 2.5GHz. The reason that Sprint has this spectrum is from their short-lived rollout of WiMax technology with Clear.
High-band frequencies can provide several advantages when deploying technologies enabling Gigabit-class LTE and on the road to 5G.
First, the antenna size needed in the 2.5GHz range is substantially smaller than the antenna size for a more common LTE frequency like 1900MHz. This means that when looking to deploy cellular sites utilizing technologies like 4X4 MIMO antenna arrays, Sprint can make smaller cell sites and be more nimble by placing them in areas where they are seeing substantial network load.

Asus’ PadFone is a cool idea that’s never yet made it stateside—but that’s all about to change with the advent of the PadFone X, which will be headed exclusively to AT&T at some point in the future (TBA). The PadFone was a concept first introduced in 2011 that involves a smartphone which docks with a larger tablet for seamless transition between screen sizes. Everything is also constantly and instantly synced between the two gadgets via independent Wi-Fi and cellular data connections without the need to manually invoke synchronization. Any applications which are currently running on either device will automatically resize to fit the other screen when the PadFone is docked or undocked.
It’s a really clever design that we’re happy to see is coming to the US. Pricing and detailed specifications are still up in the air, but here’s what we do know about it:
- 5-inch 1080p screen
- Docks with a 9-inch 1080p companion tablet station
- Brushed metal frame with soft-touch back cover
- Dual front speakers
A “large” battery in the companion tablet station also allows for charging of the 5-inch PadFone when docked, providing “2 times longer” battery life.
The PadFone X supports a couple of new technologies on AT&T’s network as well to help improve voice quality:
- Voice over LTE (VoLTE): This is a new technology which allows for much better quality voice transmission using a codec referred to as HD Voice (technically called Adaptive Multi-Rate Wideband).
- Carrier Aggregation: A part of LTE Advanced, this allows for the grouping of up to five separate 20 MHz bands to produce up to a maximum aggregated bandwidth of 100 MHz. Essentially, it translates to better voice quality for the PadFone X.
More details about the PadFone X will be announced soon.
In the meantime, Asus also unveiled the PadFone mini, which is not tethered to any particular carrier. It’s essentially a more basic version of the PadFone X, and judging by the screen resolution alone (800x480 for the phone and 1280x800 for the tablet), it’s clear that it’s intended more for the mainstream market than tech enthusiasts.
The full specs are as follows:
- CPU: Intel Atom Z2560 processor
- RAM: 1GB LPDDR2 RAM
- Storage: 8 GB internal w/ Micro SD slot for expansion
- Phone: 800x480 IPS
- Station: 1280x800 IPS
- Camera: 8 MP rear camera (f/2.0) and 2 MP front-facing camera
- Phone: 4.5Wh, 1170mAh, non-removable polymer battery
- Station: 8.3Wh, 2100mAh, non-removable polymer battery
- Phone: 116g; 124.42 (L) x 61.44 (W) x 6.3-11.2 (H) mm
- Station: 260g; 199.85 (L) x 119.43 (W) x 13.91 (H) mm
- Five color choices: Black, White, Red, Blue, and Yellow
- Dual-SIM support
- New ZenUI interface layered atop Android OS, which provides new apps, visual tweaks, and some useful extras.
