Qualcomm has announced the first samples of the LTE modem X20 LTE speeds of cellular data networks up to 1.2 GB/s. the Chips are made in compliance with the advanced 10-nanometer process technology FinFET.
We are talking about decision represents the seventh generation of multimode LTE modems the company and the second generation of its Gigabit solutions LTE. The modem for the first time in the industry provides commercial support for LTE Category 18, so that the maximum download speed reaches 1.2 GB/s.
In addition, the modem provides support for the aggregation of the carrier frequencies of 5 × 20 MHz for downstream communication lines of the radio-frequency FDD and TDD. X20 Snapdragon LTE obnocious is the first commercial solution that enables mode 4 × 4 MIMO over all three carrier aggregated LTE-frequencies — as a result, supports simultaneous reception of up to 12 LTE data spatial streams (each with bit rate up to 100 Mbps).
Finally, the first LTE modem, the Snapdragon it supports Dual SIM Dual VoLTE (DSDV). The maximum transmission speed from user to the base station, provide the X20 Snapdragon LTE is 150 Mbps.
X20 Snapdragon LTE supports all the key mobile communication technologies (LTE FDD, LTE TDD, WCDMA, TD-SCDMA, EV-DO, CDMA 1x and GSM/EDGE) and LTE Broadcast and VoLTE support high-quality audio, Ultra HD Voice using the EVS codec. The modem is compatible with 40 frequency bands and has more than 1000 variants of aggregation of the carrier frequencies.
Qualcomm said that the chip allows to achieve the speed and quality of wireless Internet, close to the performance of fiber-optic networks.
Note that in the iPhone 7 and iPhone 7 Plus, Apple uses two types of LTE modems. In models A1778 A1784 and installed the Intel chip XMM7360 (GSM only), but the versions and A1660 A1661 module is used MDM9564M Qualcomm (GSM/LTE). The tests showed that in all cases, the iPhone 7 with a modem from company Intel was the loser. And the lag from the models flagship with a Qualcomm reaches 30%.
Apple is likely to appeal to new solutions Qualcomm. Although the background of judicial confrontation of the first companies to be more difficult to negotiate with the chip maker. In January of this year, the iPhone maker accused the provider in a non-competitive behavior in the market, refusal of payment of the refund amount for the transaction and forced to buy products only from her.
