Robert Cooper - Ofcom - Bands under study for 5G
The document discusses studies being conducted by various international and national bodies on frequency bands being considered for 5G technologies. The International Telecommunication Union is studying bands between 24.25-86 GHz, and will next meet in spring 2017. The UK supports identifying global bands for 5G and early harmonization of a pioneer band in Europe. Studies are focusing on bands including 3400-3800 MHz, which the UK plans to auction 150 MHz of and consider sharing arrangements for the remainder. Tests can be conducted under non-operational licenses after coordination to prevent interference.

Radio Design Webinar: Optimising Your 700 MHz Deployments
This document provides an overview of 700MHz spectrum including its commercial status, main frequencies by region, and why it is important for 5G networks. Key points include:
- 700MHz spectrum is being cleared for mobile use in many regions to meet targets by 2020-2027 for coverage including rural areas.
- It can provide widespread coverage due to favorable propagation characteristics and is essential for applications requiring ultra-reliable communications like IoT.
- Technical challenges in deploying 5G include adding new spectrum and radios to existing sites which risks exceeding space and wind loading limits. Solutions like antenna combiners and remote radio heads help overcome these challenges cost effectively.

This document analyzes quality of service (QOS) parameters in UMTS networks based on handovers and sectorization. It discusses:
1) Handovers play a major role in continuing services as users move between cell boundaries. Sectorization divides cells into sectors using directional antennas to reduce interference and increase capacity.
2) Simulations are conducted using OPNET to analyze soft and hard handovers as a user moves between sectors. Results show the active cell count changes and cells added and removed from the active set.
3) Analysis of soft and hard handovers using applications like HTTP shows that soft handovers provide better performance with lower object and page response times, ensuring seamless service continuity.
NB-IoT: a sustainable technology for connecting billions of devices
Under the umbrella of 3GPP, radio-access technologies for mobile broadband have evolved effectively to provide connectivity to billions of subscribers and things. Within this ecosystem, the standardization of a radio technology for massive MTC applications – narrowband IoT (NB-IoT) – is also evolving. The aim is for this technology to provide cost-effective connectivity to billions of IoT devices, supporting low power consumption, the use of low-cost devices, and provision of excellent coverage – all rolled out as software on top of existing LTE infrastructure. The design of NB-IoT mimics that of LTE, facilitating radio network evolution and efficient coexistence with MBB, reducing time to market, and reaping the benefits of standardization and economies of scale.
The IoT embeds a broad range of MTC applications, and among the different types, massive MTC – including applications like smart metering, agriculture and real estate monitoring – sets a number of performance targets for connectivity. Attempting to meet these IoT targets using a radio-access technology designed for mobile broadband, however, doesn't make economic sense. Networks that provide connectivity to massive MTC applications need a radio-access technology that can deliver widespread coverage and low power consumption, often in signal-challenged locations. Hence the need for narrowband-IoT (NB-IoT).
NB-IoT is a 3GPP radio-access technology designed to meet the connectivity requirements for massive MTC applications, as well as the design targets for IoT including low device cost, extended coverage, 40 devices per household, long battery life, and uplink latency of under 10 seconds.
NB-IoT enjoys all the benefits of licensed spectrum, the feature richness of EPC, and the overall ecosystem spread of 3GPP. At the same time, NB-IoT has been designed to meet the challenging TCO structure of the IoT market.
This articles reveals how NB-IoT is being designed and how it can be deployed in GSM spectrum, within an LTE carrier, or in an LTE or WCDMA guard band.

Wireless networks gsm cdma
The document provides an overview of the key differences between GSM and CDMA wireless networks. It discusses differences in their radio spectrum usage, network architectures, radio channel technologies, call processing, and evolution to 3G. The network architectures for both include mobile stations, base stations, base station controllers, and mobile switching centers. However, GSM uses TDMA while CDMA uses direct sequence spread spectrum. CDMA allows frequency reuse in all cells while GSM requires frequency assignments between adjacent cells. The document also compares their historical development and technical parameters.
Whitepaper tipping the_scale_for_5g
The document discusses key technology enablers for 5G networks, including 5G radio, ultra dense heterogeneous networks, mobile edge computing, network function virtualization, software defined networking, network slicing, and internet of things. The objectives of 5G include supporting peak data rates of 10Gbps, guaranteed rates of 50Mbps, latency of 1ms for radio access and 5ms end-to-end, high mobility up to 500km/hr, location accuracy of less than a meter, and connectivity for over 1 million devices per square kilometer. 5G aims to enable a wide range of new applications through these advanced capabilities.

5G Spectrum in EUROPE
This document summarizes the views on 5G spectrum from the GSA Spectrum Group European regional team. It outlines that both low and high frequency spectrum bands will be needed to meet the diverse 5G usage scenarios. The "pioneer bands" identified by the European Union for 5G trials and early commercial deployment include 700 MHz, 3400-3800 MHz, and 24.25-27.5 GHz bands. The 3400-3800 MHz (C-band) is particularly important as it can provide wide contiguous blocks of 100 MHz or more per operator. However, the C-band spectrum is currently fragmented in Europe and consolidation is needed to enable 5G deployment by 2020.
5G Fundamentals
The document discusses 5G fundamentals including:
- 5G is expected to enable a fully mobile and connected society from 2020 onward.
- 5G will require new technologies like millimeter wave communications, massive MIMO, and network densification to meet requirements for high data rates, low latency, and connectivity of many devices.
- Millimeter wave frequencies above 30 GHz offer vast amounts of unused spectrum but propagation is sensitive to blockages. Massive MIMO using hundreds of antennas can compensate through beamforming.

406MHz - 430MHz Sharing and Trials
The document discusses the 406.1-430 MHz frequency range and updates from the UK Spectrum Policy Forum meeting. It notes there appears to be demand for spectrum from multiple industry players in this range due to the UK UHF2 band plan. It also mentions the potential for increased sharing between the private sector and Ministry of Defense, subject to technical studies. Ofcom is establishing a group to examine the nature of demand in this area and consider remaining process issues.
CMU Update Review
The Spectrum Central Management Unit (CMU) is responsible for delivering the UK's public sector spectrum release programme and improving strategic spectrum use across government. The CMU brings a commercial and policy perspective to managing spectrum. Its objectives are to release spectrum from public to private use to generate economic and financial value. Over 384MHz of spectrum has already been released or shared towards the programme's 2022 target of releasing 750MHz below 10GHz. Challenges include changing spectrum needs, pressure for more efficient use, and balancing commercial and departmental priorities. Relationships and evidence are key to progressing decisions on release or sharing.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
