We’re barely out of the gates with 802.11n, and we already have two new emerging standards that are likely to shake up the wireless world: 802.11ac and 802.11ad. 802.11ac is in many ways a "lessons learned" from 802.11n. It employs many of the same techniques to achieve even greater data rates, while requiring less power than with 802.11n – one of its biggest challenges. 802.11ad will expand data rates even further, taking advantage of new spectrum, which will enable entirely new uses cases for 802.11.
The future of Wi-Fi remains very strong. It is already way beyond critical mass, and with 802.11ac and 802.11ad it will remain the go-to-solution for the last 100 yards of any data network, and perhaps more. Users are now dependent on Wi-Fi, and there's nothing even close in the market that's ready to take its place. Please join us to discover how these new specifications will further entrench 802.11, where they’re likely to be used first, and whether or not you should be preparing yourself for a technology upgrade in the near future.
In this web seminar, we will cover:
- Current timeline in 802.11 development
- Characteristics of 802.11ac and 802.11ad
- Improvements over 802.11n
- Potential use cases for 802.11ac and 802.11ad
What you will learn:
- Whether 802.11ac and 802.11ad will have an enterprise footprint
- How 802.11ac and 802.11ad will integrate with current 802.11 deployments
- When you should be planning for a technology upgrade

Wireless Standards Wi Fi 6 Evolution and Wi Fi 7ijtsrd
IEEE standardized wireless technologies as 802.11, 802.11a b g n, 802.11ac. 802.11 legacy was released by IEEE in 1997. IEEE 802.11b was made available to users through Wi Fi routers. With 802.11g n increased the network capacity and data throughput support. 802.11n or Wi Fi 4 introduced MIMO technology. Downlink MU MIMO was one of the main features of 802.11ac or Wi Fi 5. The latest 802.11ax or Wi Fi 6 supports both downlink and uplink MU MIMO. The use of OFDMA, dual bands, Target Wake Time technologies will help in handling traffic offloaded from the 5G wireless network and help in catering to dynamic network needs, handling massive dense IoT networks, and high throughput demands. Wi Fi Alliance started working on the next wireless generation that is IEEE 802.11be or Wi Fi 7. Wi Fi 7 will be standardized by 2023.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Goodbye Windows 11: Make Way for Nitrux Linux 3.5.0!SOFTTECHHUB
As the digital landscape continually evolves, operating systems play a critical role in shaping user experiences and productivity. The launch of Nitrux Linux 3.5.0 marks a significant milestone, offering a robust alternative to traditional systems such as Windows 11. This article delves into the essence of Nitrux Linux 3.5.0, exploring its unique features, advantages, and how it stands as a compelling choice for both casual users and tech enthusiasts.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

3. 1. WI-FI: UNLICENSED, GLOBAL
AND EVERYWHERE
It is not hard to see the appeal of wireless LAN (WLAN) technology, commonly referred
to as Wi-Fi: a set of unlicensed wireless spectrum bands that can be used globally without
restrictions, fueled by the vast number of portable devices supporting it in a wide variety
of variants (IEEE 802.a/b/g/n).
The global numbers for public and private hotspots (zones in which Wi-Fi is used) at
the end of 2011 were estimated to be 1.3 million and 345 million, respectively (Informa
Telecoms & Media, see Figure 1). These numbers, together with predictions for the future
by the same analyst firm, show that usage of Wi-Fi technology will continue on a steady
rise for years to come.

The use of public Wi-Fi hotspots comes with a number of problems:
• Inconsistent coverage and performance
• Potential for congestion due to the shared medium with no stringent traffic policy and
Quality of Service (QoS) control
• Less-than-perfect security
• A complex and at times complicated login procedure, which calls for expert knowledge
about Wi-Fi protocols in order to find a network and configure security and login settings

4. The use of public Wi-Fi hotspots also includes a diverse range of pricing options, including
many free and pay-per-use options. The strong appeal to break away from the prohibitively
pricy cellular data plans and high costs of roaming was enough to make Wi-Fi a de facto
choice for semi-nomadic wireless data use globally.
The further adoption of Wi-Fi will be stimulated by technological improvements aimed
at the use of wider and different spectral bands (IEEE 802.11ac, IEEE 802.11af) and
variants of techniques that have already found a place in the cellular world, such as
multi-user MIMO (MU-MIMO).
The biggest boost to even wider adoption of Wi-Fi may result from HotSpot 2.0, an
industry-wide initiative driven by the Wi-Fi Alliance (WFA) and aimed at facilitating and
automating secure and trusted Wi-Fi connection with the ability to use a variety of user-
or device-based credentials. HotSpot 2.0 is built around a set of new IEEE specifications
(see Figure 2):
• IEEE 802.11u: network discovery
• IEEE 802.11i: encryption
• IEEE 802.11x: authentication
Hotspot 2.0 promises to automate network discovery, registration, provisioning and
network connectivity – steps that today are manual when a Wi-Fi user connects to
a given hotspot.

5. 2. CARRIER WI-FI
The exponential growth of data traffic on wireless cellular infrastructures over the last
several years has been matched or even surpassed by a phenomenal increase in Wi-Fi
traffic originating from Wi-Fi-enabled smartphones and tablets.
From individual homes and workplaces, to coffee shops, retail stores, hotels and airports
(and yes, even on the planes), Wi-Fi hotspots are continuing to proliferate and are becoming
ubiquitous for semi-nomadic data connectivity. While the appeal of Wi-Fi lies primarily
in its availability and relatively easy configuration, the use of Wi-Fi comes with the
burden of:
• Shared (unlicensed) spectrum
• No guarantees for network performance and QoS
• A potentially high price (for example, daily or hourly fees)
• The need to manage access configuration for many Wi-Fi hot spots through
protocols and passwords
• Many security concerns
Historically, Wi-Fi hotspots have been “dark corners” on coverage maps of mobile operators
because at these hotspots the operators start losing visibility into their customers: insight
into their connectivity and enhanced communication preferences (for example, context and
location). At these dark corners, the end-user data services riding over Wi-Fi start traversing
alternative network infrastructures that do not always belong to wireless operators.
The same situation is also valid for the wireline operators, including cable operators and
multiple service operators (MSOs). While their service offering has been driven by large
bandwidth interconnectivity with static, big-screen requirements (Internet over DSL
or cable, IPTV at home, enterprise connectivity), they also see the opportunity in the
“smartphone revolution” and would like to capitalize on it.
With Wi-Fi’s maturity in both technology evolution and standards development (for example,
MIMO and IEEE 802.11u), wireless, wireline and converged operators alike are looking at
Wi-Fi technology as an option to increase their service and business reach. Mobile service
providers and wireless operators view Wi-Fi as another wireless technology that can augment
their macro and small cell networks with affordable coverage and capacity, and with
universal acceptance. Wireline providers view Wi-Fi as a new opportunity to light up
the ends of their last miles to attract more customers and also to leverage their overall
network for reselling and wholesaling opportunities. Obviously, the ability to deal with
unlicensed spectrum has an additional appeal for all of these service providers and
network operators.
Since 2010, many different approaches have been considered, examined and even
deployed to allow the integration of Wi-Fi hotspots into wireless and wireline networks.
While these approaches have been somewhat standardized, they still represent many
different options, and often they mix different technologies to ensure the end-device
connectivity. As a result, there is increased management and billing/charging complexity.
In practice, many instances of operator-owned Wi-Fi rollouts have resulted in parallel
network infrastructures with duplication of separate networks as well as subscriber/policy
and traffic management systems, as seen in Figure 3.

Until recently, standards-based approaches for carrier Wi-Fi have been based on treating
WLAN (Wi-Fi) as untrusted access and have required the use of dedicated network
elements which otherwise might not have been needed.
The latest 3GPP standards work is focused on trusted WLAN access to evolved packet core
and based on 3GPP R11 SaMOG (S2a-based Mobility over GTP), as shown in Figure 4.

7. This approach leverages improved WLAN security (based on IEEE 802.11-2007, IEEE
802.11i, Advanced Encryption Standard) and more efficient secure tunnel management
(tunnels between Wi-Fi access points and the WLAN gateway), eliminating the need for
Enhanced Packet Data Gateway (ePDG) or Home Agent (HA) elements in 3GPP-only
network environments. This approach results in the ability to address Internet offload
directly from the Trusted WLAN gateway instead of requiring the traffic to cross the
backhaul network through the packet core.
There are few or no changes in end-user equipment (mobile terminals) because this
approach replaces the large-scale IPsec connectivity requirement between end-user
devices and a gateway (potentially millions), per previous standards, with manageable
scaling of secure tunnels between access points (APs) and a gateway (potentially thousands)
using Generic Routing Encapsulation (GRE) or IPsec. With protocol support on the WLAN
for interfacing Authentication, Authorization and Accounting (AAA) servers, this model
allows easy integration with a network operator’s billing and charging systems while
ensuring AP-cellular inter-mobility.

WI-FI SOLUTION AND A HIGH LEVERAGE
NETWORK FRAMEWORK
As an inventor, innovator and leader in all types of wireless technologies, Alcatel-Lucent
has been investigating Wi-Fi to create and deliver a comprehensive solution for easy
integration of Wi-Fi – both as an access technology and as a service — into network
infrastructures and service offerings of wireless and wireline network operators and
service providers.
The Alcatel-Lucent lightRadio™ Wi-Fi solution enables extending wireless coverage
and increasing the network capacity delivered to end users and their mobile devices
(for example, smartphones, tablets and netbooks). Operator-managed and controlled
Wi-Fi APs are fully integrated with the overall network infrastructure to ensure seamless
connectivity and an enriched end-user experience.
With Alcatel-Lucent, Wi-Fi no longer needs to be delivered as another parallel infrastructure
that incurs additional CAPEX and OPEX and has extra complexity in the form of a separate
network and separate subscriber/policy and traffic management systems. Wi-Fi technology
becomes simply another wireless technology for network operators to manage and include
as part of a larger heterogeneous RAN or wireline access/service strategy — and this is
essential to preserve/expand the customer base and offer a more complete solution.
With the Alcatel-Lucent lightRadio Wi-Fi solution, Wi-Fi can be integrated with the rest
of the operator’s network in a cost-effective and trusted manner, allowing the network
to become a strategic platform for service innovation and revenue growth. At the same
time, the lightRadioWi-Fi solution offers the benefits of traffic offload – using the most
appropriate and cost-effective part of the network to reduce overall network costs.
This solution is based on the industry-leading Alcatel-Lucent High Leverage Network™
(HLN) evolution framework. As is shown in Figure 5, HLN allows service providers to
extract more value from the network, harness Application Enablement and turn challenges
into growth opportunities for long-term business success.

4. ALCATEL-LUCENT lightRadio WI-FI
SOLUTION FOR WIRELESS SERVICE PROVIDERS
The Alcatel-Lucent lightRadio Wi-Fi solution is equally applicable to wireless service
providers and network operators – and to wireline network operators (fixed service
providers, cable operators/MSOs) who plan to incorporate Wi-Fi access either as a part
of their service offering or as a means to boost their revenues through reselling and
wholesaling opportunities.
The solution reduces the overall complexity for both end users and service providers.
Relying on the latest advances in 3GPP and IEEE standards, it allows easy, secure and
trusted Wi-Fi access with zero configuration for end users, improving their experience
with seamless connectivity and mobility between Wi-Fi and the cellular network.
For network operators, the lightRadio Wi-Fi solution creates an opportunity to further
improve their network and subscriber yield.

ALCATEL-LUCENT WIRELESS
PACKET CORE
The extension of wireless access coverage and capacity that comes with the Alcatel-Lucent
lightRadio Wi-Fi solution has a direct impact on the wireless packet core. All end-user
and/or end-device traffic that may have used alternative wireless and transport infra-
structures (such as end-user traffic traversing over third-party Wi-Fi hotspots and Wi-Fi
backhaul networks) must now be accommodated in the wireless packet core to achieve
full management of end-users’ QoS/QoE with seamless mobility, connectivity and policy
management, for millions of connections, in real time.
To cope with this influx of bandwidth and signaling caused by the addition of users,
connected devices and network applications that are served by the lightRadio Wi-Fi
solution, the wireless packet core needs to deliver high data and control plane performance
with the scalability required for massive delivery of wireless broadband — to potentially
millions of users and devices.

11. Alcatel-Lucent Wireless Packet Core has been engineered for the further evolution of
broadband to address the multi-dimensional and exponential increase in the number of
users, devices and applications as well as higher bandwidth, lower latency and longer
duration of data sessions.
With Alcatel-Lucent Wireless Packet Core, mobile operators and service providers can
converge and consolidate their wireless core — for 2G/3G/3G+, LTE/4G and now
Wi-Fi on a super-scalable all-IP multiservice infrastructure with exceptional performance,
advanced QoS capabilities and high operational flexibility. Significant savings can be
obtained from the packet core ability to deliver traffic more reliably and cost-efficiently
and by leveraging network intelligence and policy management to generate new forms
of revenues from new network services and applications. Alcatel-Lucent Wireless Packet
Core is also a foundation for the overall core convergence — for wireless, wireline and
converged network environments.
As shown in Figure 8, Alcatel-Lucent Wireless Packet Core comprises:
• Alcatel-Lucent 7750 SR, an industry-leading service routing platform that provides
converged data/user plane mobile gateway functions (SGW/PGW/GGSN) for 2G,
