Check out this #infographic that explains how #CBRS 2.0 will bring significant enhancements to the CBRS band, including reduced protected areas, extended heartbeat for devices, and improved coexistence among users, enabling even wider adoption of the shared spectrum technology. https://lnkd.in/e6mpiaq6

AT&T has proposed to relocate the CBRS band and hold a reverse auction to evict PAL licence holders. As is expected, this has been bet my fierce opposition from CBRS users who are outraged at the plans. Full details in Mirva Villa's story below. IMO it is an odd proposal. The CBRS band is now well established in the US, and there have not been any hints that the FCC is interested in a radical change. In fact, the regulator often boasts about CBRS internationally and has actually been working to make a series of minor improvements to the regime, hinting at its long term commitment to the idea. That being said, measuring the "success" of CBRS is difficult. Yes, the band is providing value to thousands of licensees, but it is also possible that if we are measuring success by the number of sites, mobile operators could make more extensive use of the band. (Although this is likely a flawed measure of success). It will be up to the FCC to decide what is a better use, but evidence so far does suggest they are committed to maintaining a diverse cohort of users in CBRS.

The success of CBRS demonstrates that sharing regimes can and should be deployed in other key spectrum bands. The reality is that dynamic spectrum sharing: ✅ Advances Investment ✅ Drives Innovation ✅ Spurs Competition ✅ Supports Diverse Use Cases ✅ Maximizes a Limited Resource ✅ Recognized Internationally More from Spectrum for the Future: https://bit.ly/3TF3CJR

CBRS 2.0 is here! Check out what the major enhancements to the #CBRS band are and how they will further unlock the potential of CBRS with greater performance, reliability, and reduced interference. https://lnkd.in/egdChca9 #sharedspectrum

In today's PolicyTracker story, we have a look at the reaction to AT&T's proposal that the #CBRS should be moved to different frequencies so MNOs can have more spectrum for 5G. AT&T says it's a win-win, as MNOs get 530 MHz of contiguous spectrum and CBRS users get 200 MHz—50 MHz more than they have currently. Those outside the mobile industry are not so sure. "AT&T doesn’t just want to kill competition in the CBRS band, they want exclusive control over spectrum currently shared among a diverse array of users," says Tamara Smith of Spectrum for the Future (members include the Dynamic Spectrum Alliance and the big US cable operators). "Odd as it may seem to AT&T, CBRS was not designed for carriers and 5G," said Harold Feld, Senior Vice President of Public Knowledge®. "This band does not need a disruptive makeover simply to benefit AT&T and other carriers." Full story: https://lnkd.in/eHj9wVZR

Interesting improvements from CBRS 2.0: - Longer heartbeats (from 4 min to 24 hours) allows minimum disruptance when the CBSD-SAS link is down. - Smaller DPA regions brings less preemption probability to the CBSD's which are at protected areas. - GAA coexistence facilitates interference mitigation, specially when enterprises and SP's uses GAA at close locations #private5g #cbrs #privatenetworks

CBR Test: • For classifying and evaluating sub-grade and base course materials * for flexible pavements *. • Empirical test: not true representation of resilient modulus. • Generally CBR decreases with increase in penetration. Hence, CBR5 < CBR2 - 3mm, but if we get greater value of CBR5 then adopt if after confirmation. • Standard plunger → 50 mm (1.25 mm/min)

In the U.S., CBRS is playing a bigger and bigger role in connectivity - both for ISPs and for Critical Infrastructure networks.
