Qualcomm Suspends EV-DV Development
Mar 4, 2005, 4:45 PM by (staff)
Due to a lack of interest from carriers, not just in the US but world-wide, Qualcomm has suspended development of EV-DV chipsets. EV-DV is a high speed data standard designed as a faster, more efficient alternative to EV-DO on CDMA 2000 networks. However carriers have instead chosen to launch EV-DO networks since hardware for them is available today, and the next revision of EV-DO (rev. A) adds many of the speed boosts and features that EV-DV offers while maintaining backwards compatibility. Qualcomm has not pronounced EV-DV dead yet, maintaining it will monitor the market for interest in the standard.
Qualcomm Debuts Ultrasonic Fingerprint Scanning Tech
Qualcomm today announced Snapdragon Sense ID, a new fingerprint scanning technology that makes a 3D map of a fingerprint using ultrasonic technology. It's designed to integrate into phone bezels.
Qualcomm Develops 5G Test Platform
Qualcomm has created what it calls a prototype 5G system and trial platform. The 5G New Radio (NR) prototype is able to function across a wide range of spectrum bands, primarily below 6 GHz, and can achieve multi-gigabit per second data rates and low latency.
Qualcomm's Next Target Is Unlicensed LTE Over 5GHz
Qualcomm today announced its initial foray with LTE into the unlicensed 5GHz band, spectrum that is normally reserved for WiFi networks. Qualcomm believes LTE-U, or LTE in unlicensed spectrum, could help carriers fill in blank spots with small cells.
Qualcomm Adds LTE Cat 9 to Snapdragon 810
Qualcomm today announced it has improved the Snapdragon 810 processor by incorporating an LTE Category 9 Carrier Aggregation modem. With LTE Cat 9 on board, Qualcomm claims the 810 has reached download speeds of 450Mbps over three 20MHz LTE carriers in lab-based tests.
Huawei Takes Aim at Snapdragon 810 with Kirin 950
Huawei today announced the Kirin 950 chipset for phones, which is designed to compete with Qualcomm Snapdragon 800-series chipsets in higher-end phones. Huawei claims that the 950 is 25% faster and 44% more power-efficient than the Snapdragon 810, Qualcomm's current flagship chip.
Kind of sad
EV-DV killed by DO
The real story here is that operators want a full IP network and an air interface with low latency to do VoIP.
The other story is the fact that Qualcomm has reduced the latency on EV-DO enough so people think VoIP over EV-DO might be doable in the not so distant future.
I beleive latency on the latest EV-DO release (the one sprint will deploy) is sub 100 ms. That is huge compared to the 300 to 500 ms it is with 1xrtt and its going to get better.
i cant wait for Wimax and Flarion (ofdm) though. thats going to be fun.
