The Android 4 phone features and HTC Sense 4.0 overlay, 1.5 GHz Dual-core Qualcomm Krait CPU, 4.3 in AMOLED with 540×960 resolution, an 8 megapixel back camera with HDR, autofocus, smart LED flash and a front-facing camera with VGA resolution.
The phone is covered with Gorilla glass, and an oxidized finish said to make the body five times stronger than the bare aluminum.
It also features T-Mobile’s HSPA 42Mbps connection, a micro-USB 2.0 (5-pin) port with mobile high-definition video link (MHL) for USB or HDMI connection, Wi-Fi 802.11b/g/n DLNA for wirelessly streaming media from the phone to a compatible TV or computer and Bluetooth 4.0 with low energy technology.
Bluetooth 4.0 features ultra-low power consumption, with the ability to run for years on standard, coin-cell batteries, with low cost, multi-vendor interoperability and enhanced range. It was first available in the iPhone 4S and the new iPad and is also available in the Galaxy S III (but not other recent phones such as the Samsung Galaxy Nexus).
Bluetooth 4.0-enabled smartphones will work on a variety of Bluetooth 4.0 devices, including:
- MOTOACTV fitness tracker with both ANT+ and Bluetooth Low Energy in it.
- Wahoo Blue HR heart-rate monitor. The $79 device connects wirelessly without the need for any adapters, delivering real-time heart rate data through the free Wahoo Fitness App.
- Polar H7 heart strap. Polar makes a wide variety of heart rate sensors and fitness watches with sophisticated training features.
- Find My Car Smarter app. Finds and marks the location when you park your car. A Bluetooth v4.0 enabled dongle plugs into your car’s cigarette lighter and a matching app that runs on the Apple iPhone 4S.
- Casio G-Shock smart watch. Can notify you with a tone or vibration when you receive new calls or emails, and displays a visible alert.
- MOTOACTV. A fitness tracker, smart music player and training system from Motorola.
- Nike Fuelband uses Bluetooth 4 to communicate. Both Bluetooth versions 3.0 and 4.0 can talk to NFC hardware in phones to make pairing a simple process of tapping the two devices together.
- AT&T’s mHealth Platform will provide a single environment where consumers can securely aggregate their data from across silos — insurance companies, doctor’s offices, connected devices, applications. Intel Health has a similar initiative.
Bluetooth Low Energy is likely to become a popular method of connecting bike computers to sensors on your body or bike.
Currently, Garmin’s ANT protocol, also using 2.4 GHz, is often used for ultra-low power networking applications in sport, wellness, home and industrial automation. The ANT+ Alliance is organized by Dynastream Innovations, a subsidiary of Garmin. The Garmin Edge 800 is a high-end ($400) touchscreen GPS bike computer.
The ANT+ Alliance has more than 300 members, including Adidas AG, Concept2, Garmin, Suunto, McLaren, Microsoft, Sony Ericsson, Texas Instruments, Timex and Trek. Devices like the $99 Fitbit electronic pedometer use the ANT protocol. Some Sony Ericsson phones include support for ANT+.
Bluetooth 4.0 with Low Energy, now beginning to appear in smartphones, may give ANT a run for the money. LG’s first Quad-Core smartphone, the Optimus 4X HD, is now available for purchase in Europe. The Android 4 phone uses a quadcore Tegra 3 with a 4.7-inch True HD IPS display with a resolution of 1280 x 720 and includes support for Bluetooth LE.
Windows 8 will support Bluetooth v4.0, paving the way for the first big wave of Smart Ready PCs in late 2012. Hopefully, the new Macs announced today will also support Bluetooth 4.0.
