This document discusses how to extend LTE coverage with limited RRU capacity at DTAC's live network. It provides information on LTE technology power consumption, the LTE formula for cell reference signal (CRS) gain using power boosting (PB), demo predictions of CRS gain using an asset planning tool, calculations of coverage area and population comparisons based on CRS gain, configuration of CRS gain in three vendors' equipment, and recommendations for PB and PA values in DTAC's live LTE network.
ePRTC in data centers – GNSS backup as a service (GBaaS)ADVA
Data center network architecture is vulnerable to GNSS-related attacks such as jamming and spoofing. That’s why enhanced primary reference time clocks (ePRTCs) that utilize a stable frequency standard (such as a cesium clock) are increasingly being leveraged as a backup source. Nir Laufer's WSTS presentation explored several network architectures that utilize ePRTC in data center network synchronization to provide secure and resilient time.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

How to calculate and find the Total Power of PDSCH become
Symbol
12REs
/1PRB
15Khz
RE
1. RE(Resource Element)
'= Engergy (Power) allocated to 1 RE is calleds EPRE(Energy Per 1Resource Element)
2. RSRP =If there is no noise at all, RSRP would be same as EPRE you set for Reference Signal
'= RE for reference Signal Average Power of all the RS(Reference Signal within a Symbol)
3. Total Power PDSCH This value may vary with different symbols
-Symbol 0 in first slot is made up of multiple component - PCFICH, HICH, RS.
-Symbol 4 is made up of PDSCH and Reference signal).
Within Reference Signal
1.RSRP=(p(51)+p(57))/2
2.Total Power PDSCH= p(49)+p(52)+p(53)+p(55)+p(56)+p(58)+p(59)+p(60)
= EPRE PDSCH x 10 (In linear Scale)
3.Total Power PDSCH all Channel
=(RSRP x 2) + Total Power PDSCH
4.Total Power PDSCH all Channel
= EPRE for PDSCH x Number of PDSCH RE
= EPRE for PDSCH (in dBm) + 10 Log(Number of PDSCH RE)
Without Reference Signal
1.RSRP=N/A (since there is NO RS)
2Ttoal Power PDSCH
=p(25)+p(26)+p(27)+p(28)+p(29)+p(30)+p(31)+p(32)+p(33)+p(34)+p(35)+p(36)
=EPRE PDSCHx12 (In linear Scale)
3.Total Power PDSCH all Channel
=Total Power PDSCH
4.Total Power of PDSCH (Without Reference Signal)
= EPRE for PDSCH x Number of RB x 12 (assuming for the symbol with no
Reference Signal)
= EPRE for PDSCH + 10 Log(Number of RB x 12)

How to calculate and find the Total Power of PDSCH become
Example
If DTAC Network allocated at -90 dBm/EPRE for PDSCH and allocated 100 RBs for the PDSCH(BW:20MHz),
Find the Total Power of PDSCH become as follows.
Total Power of PDSCH (in dB/dBm scale )
= EPRE for PDSCH + 10 Log(Number of RB x 12)
= -90 + 10 Log(100 x 12)
= -90 + 30.8
= - 59.2 dBm
If DTAC allocated at -95 dBm Find the Total Power of PDSCH become as follows.
= -95 + 10 Log(100 x 12)
= -95 + 30.8
= -64.2 dBm
If DTAC allocated at -100 dBm Find the Total Power of PDSCH become as follows.
= -100 + 10 Log(100 x 12)
= -100 + 30.8
= -69.2 dBm
If DTAC allocated at -105 dBm Find the Total Power of PDSCH become as follows.
= -105 + 10 Log(100 x 12)
= -105 + 30.8
= -74.2 dBm
If DTAC allocated at -110 dBm Find the Total Power of PDSCH become as follows.
= -110 + 10 Log(100 x 12)
= -110 + 30.8
= -79.2 dBm
