Qualcomm successfully implemented gigabit LTE connectivity: This speed is also unprecedented
On September 21, Qualcomm announced that Telstra, a joint venture between Ericsson and the Australian telecom operator, was the first to successfully implement downstream 979Mbps and upstream 129Mbps on Telstra's existing network. This speed once again refreshed the 4G network's record of success Into the Gigabit era.
Although only the test data of the operator, it is still a period of time that the consumer is actually commercial, but this is great help to promote the speed of commercial mobile broadband. The demonstration uses a test terminal equipped with the Qualcomm Snapdragon X16 LTE modem that leverages advanced connectivity technologies such as LTE-A carrier aggregation (CA), uplink 64-QAM / downlink 256-QAM and 4x4 MIMO.
When we lamented the fact that broadband has not fully entered the Fast Ethernet at home, mobile broadband has been rapidly developed and our mobile terminals are capable of Gigabit connectivity. Its download speed is already 10 times that of the first generation of LTE, even up to 500 times that of the early 3G terminals. In addition to downstream speeds, the uplink speed has tripled than most 50 Mbps LTE network rates.
At this stage, both for the consumer market or the professional market, LTE gigabyte-speed chip, Qualcomm introduced only Snapdragon X16 LTE modem. It is the first commercial gigabit LTE chip introduced in February 2016 and features a 14nm FinFET process. The Snapdragon X16 brings LTE Cat 16 download speeds of up to 1 Gbps by supporting downlink carrier aggregation up to 4x20 MHz and 256-QAM (Enhanced Rate Modulation and Demodulation) technology across FDD and TDD spectrum; Up to 2x20 MHz uplink carrier aggregation and 64-QAM, up to 150 Mbps upstream. The Snapdragon X16 also leverages 4x4 MIMO, doubling LTE throughput over the same spectrum, helping mobile operators improve network spectrum efficiency.
Earlier this year, Qualcomm has demonstrated at the MWC how the Snapdragon X16 modem achieves gigabit downstream rates by leveraging triple carrier aggregation, 4x4 MIMO on two aggregated carriers, and higher order modulation of 256-QAM. Now Qualcomm succeeded in implementing gigabit-level LTE connectivity over Telstra's network, which is the basis for our 5G adoption and a positive impetus for our current LTE mobile broadband, one more step forward in commercial adoption.
The die casting process involves the use of a furnace, metal, die casting machine, and die.
The metal, typically a non-ferrous alloy such as aluminum, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting.
The castings that are created in this process can vary greatly in size and weight, ranging from a couple ounces to 100 pounds. One common application of die cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.
Metal housings for a variety of appliances and equipment are often die cast.
Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
