Apple Iphone 6: The Outstanding Smartphone

Samsung And Apple competition is going on the next level. Both are giving each a tough competition and the reason is more profit. And Apple launched the most profitable smartphone of the generation the iPhone 6 in the later 2014. 

As for the ROM, Apple has withdrawn from the set of available options Models with Flash-memory 32 GB and 128 GB added for the iPhone 6. Prices are still going increments of $ 100, starting at $ 649 for the iPhone with 16 GB of memory. The iPhone 6 chip’s architecture is similar to the chips of Qualcomm, which greatly simplify and improve the situation of cellular communication. Firstly, instead of five varieties with different frequencies list of supported LTE, now there are only two models of iPhone 6 and iPhone 6 Plus.

The inbuilt iPhone 6 Modem MDM9625M is corresponding to category 4 LTE, which provides a bandwidth of up to 150 Mbit / s. But to get that speed, the operator shall provide a continuous range of 20 MHz or to maintain FDD-LTE (inbound and outbound channels on different carriers). A third method to obtain peak bandwidth input – Carrier Aggregation: combine two different carrier bands, necessary for forming LTE Cat 4 20 MHz band. To do this in the iPhone 6, there was a separate receiver Qualcomm WFR1620 in addition to the transceiver WTR1625L. However, despite the fact that the chip supports all standard WFR1620 frequency, iPhone 6 configuration for some ranges it is not available, in particular Band 20. Add support VoLTE – voice channel directly without shifting LTE to GSM or CDMA, is required before.

Wi-Fi module in the iPhone 6 complies with IEEE 802.11ac and support one spatial stream with theoretical bandwidth on the PHY-level 433 Mbit / s. Apple iPhone finally got support for NFC, but realized it is quite specific way. Due to the metal housing of the iPhone 6 is not possible to put a large inductive antenna, as is done in the devices of other manufacturers. Moreover, it is still not known exactly where the antenna NFC in the iPhone 6 and 6 Plus. Judging by the opening of the device, which had iFixit, the most likely candidate for the role of the antenna – the upper segment of the metal housing. And it imposes certain restrictions on the use of the interface. NFC operates in the 13.56 MHz frequency, which corresponds to a wavelength of 22 m. If the antenna is shorter than the wavelength so as presumably the iPhone 6 has (and not a traditional inductor), then sufficient signal strength cannot be achieved by it. This explains the presence of the chip Active Load Modulation, which amplifies the output signal. However, this does not improve the properties of the iPhone as a signal receiver. It is possible that in practice the machine can communicate according to NFC only if the other end of the device is a also active and passive card and NFC-tags can simply be read.

Once again, Apple is best with its iPhone 6 and now it is ready to improve its functionality with the arrival of new iOS9 update.
