Qualcomm chip gives better LTE connections

Apple’s iPhone 7 và Plus are usually powered by either Intel’s XMM7360 modem or Qualcomm’s MDM9645M, & both are assumed khổng lồ give equal performance in all scenargame ios. However, the lademo research conclusion from Cellular Insights negates this common belief.


The research firm tested the LTE performance of both modems across the three bands, B& 12(10MHz), B& 4(20MHz), & B& 7(20MHz), in the 4×2 MIMO configuration using Transmission Mode 4, notes The Register. The conclusion from the retìm kiếm was that the iPhone 7 models with the Intel modem performed 30% worse on average compared to the Qualcomm-fitted models when there was a weak signal. The Hãng sản xuất Intel Model required an adjustment of its Transport Block Size, the reason being that the Block Error rate exceeded 2%, & with a signal of -105dBm, the Blochồng Error rate reached 20%. Further, at -108dBm, it crossed 75%.

In the United States, thiết bị di động carriers Sprint và Verizon offer the Qualcomm-powered phones. AT&T và T-mobile sell Intel-powered iPhones that do not work on the CDMA-operated Sprint và Verizon networks, notes The Register. Qualcomm offers support for all U.S. carriers, and therefore, an unlocked iPhone 7 purchased on the Sprint or Verizon networks can also be operated with on AT&T’s & T-Mobile U.S.’s networks.

Intel aims to lớn make it big in 5G wireless

Meanwhile Intel is looking lớn foray inkhổng lồ the 5G wireless market after seeing the growth of the 3F and 4G di động wireless markets. This time, the chip maker is looking khổng lồ be directly involved in the high-tốc độ 5G networks & not just a tư vấn partner.

Murthy Renduchintala, head of Intel’s Smartphone and Internet of Things Group, said “Clearly Hãng sản xuất Intel was late coming khổng lồ the buổi tiệc nhỏ on 4G. But I think at least from a modem perspective sầu, we are now sitting at the tiệc ngọt table.”

Renduchintala said that until now, the company had not announced a 5G chip, but it is working in the U.S. & elsewhere with its wireless industry partners.
