Recently, Qualcomm Technology Co., Ltd. (hereinafter referred to as Qualcomm), in cooperation with Sprint and NASCAR, demonstrated the second-stage over-the-air test of the TD-LTE ultra-dense small base station network at the Phoenix International Circuit. The experimental results show that the LTE network capacity has been significantly improved, and the UltraSON technology can overcome the challenges of unplanned and ultra-dense deployment of small base stations.
Verification chip and ad hoc network technology
The trial was conducted in March 2014 during the NASCARSprintCupSeries March Phoenix City Station. As part of the trial, Qualcomm installed 31 small base stations in the garage area of ​​the Phoenix International Circuit to test density limits, measure network performance and quantify the potential impact on the user's mobile experience.
The ultra-dense network demonstration is based on Airspan's AirSynergy2000 LTE-AdvancedPico base station, which uses Qualcomm's small base station chip and UltraSON (advanced network) technology. The ultra-dense network operates on Sprint's TD-LTEband 41 band, which is equivalent to the density of 1000 base stations per square kilometer.
It is reported that the ultra-dense small base station network test enables Qualcomm to demonstrate how its chip and software solutions (including UltraSON software) improve the total throughput of the cellular network and reduce the frequent switching and signaling load of the core network.
IyadTarazi, vice president of Sprint's network division, said: "Small base stations will play a vital role in Sprint's network strategy. NASCAR is one of Sprint's most important sponsorships, so it can work with Qualcomm on the Phoenix International Circuit. We are very excited about the trial."
Small base stations are more cost effective
It is well known that traditional macrocell base towers excel in providing large area coverage, while small base station deployments provide a more cost-effective solution that delivers high levels of mobile data capacity both indoors and outdoors. Network-intensive areas have outstanding performances, such as shopping malls, restaurants, and NASCAR.
To meet the challenge of 1000 times the growth of data traffic by 2020, Qualcomm is leading the industry to maximize the efficiency of the limited licensed spectrum. In the first phase of the trial, completed in November 2013, Qualcomm demonstrated the ability of UltraSON technology to significantly reduce network signaling load while improving wireless data performance and ultra-dense small base station network service quality.
In the second phase of the trial, Qualcomm demonstrated a significant increase in capacity in ultra-dense small base station networks (compared to existing large-area cellular technologies) while leveraging UltraSON technology to deliver a superior user experience throughout the test area.
It is understood that during the NASCAR competition, the Phoenix International Circuit has a large number of racing fans, bringing challenging radio frequency (RF) conditions and a large amount of mobile data, thus becoming the implementation of Qualcomm Technology's ultra-dense small base station network test. The ideal place.
A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.
The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.
But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
