As presented at the 4G Wireless Evolution conference in Miami, January 22, 2010.
WiFI has been at the heart of the change to OFDM and MIMO solutions. It is not suprising that WiFi is a hotbed of innovation in today’s marketplace. This discussion looks at the current and future opportunities associated with WIFI and the implications for new kinds of deployment and adaptation by the LTE and WiMAX community.
Brough’s keynote address at the October 2010 4G Wireless Evolution Conference.
In it, he argues:
1. All key 4G technologies are pioneered by Wi-Fi (3-5 year lead!).
2. Wi-Fi will be the dominant solution for mobile data offload.
3. 4G technologies represent a wireless tipping point with the result they will revolutionize backhaul and eventually the first mile (via wireless ISPs).
He closes with two slides on his new wireless ISP, netBlazr.

With 802.11n ratification a distant memory, news regarding this giant leap in WLAN capability has also waned. But while 11n has quietly receded into the media background, WLANs have crept out of the cocoon of the data-only world and taken flight as full-fledged networking platforms. From dedicated 802.11 communication systems to generic voice and video over wireless with the explosive availability of smart phones, 802.11n is driving a major shift from locally available point solutions to widely distributed, highly available access for all types of applications.
Technological advances typically highlight new technological challenges, and this quiet revolution is no exception. Networks, devices, and applications all need to be monitored and managed. Mobility introduces previously unconsidered consequences. The network topology constantly changes as users access and exit the network. New devices with new capabilities crop up almost every day. This web seminar will analyze this wireless metamorphosis with a focus on addressing these key technological challenges.
In this web seminar, we will cover:
* Wireless trends
* The Wi-Fi lifecycle
* 802.11n as a driving force
* Management layers for complex wireless networks
What you will learn:
1. The importance of careful Wi-Fi design and planning
2. How to use 802.11n to your advantage
3. How to dissect and address your wireless management needs

Interop 2006: Evolution of the Networking IndustryAbner Germanow
This was a presentation from 2006 where (starting on slide 30) I described how the way consumer networking vendors built their products would ultimately upend the way enterprise vendors built products. Today, the hype around SDN, commodity switching products, and linux based network operating systems is making much of this come true.
This presentation was first given in May 2006 at the Interop trade show.
Slide 30, is where I talked about how the networking market would split from vertically organized vendors to horizontally specialized vendors. I predicted this transition would take 10 years.
At the time, the use of merchant silicon in datacenter and enterprise switching products was a rarity. Today, it is common. Then linux derivative network OSes were limited to consumer products, today they are taking over large scale cloud datacenters.
The networking market hasn’t come as far as I expected in 10 years, but it’s pretty cool much of this either came true or is on the cusp of coming true. Much more change is under way.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.

Editor's Notes
ETSI HIPERMAN following 256 OFDM mode of 802.16a
802.11c provides required information to ensure proper bridge operations, focusing on improving MAC layer for better bridging. This project is completed, and related procedures are part of the IEEE 802.11c standard. Product developers utilize this standard when developing access points. There&apos;s really not much in this standard relevant to wireless LAN installers.
802.11ma It provides Enhancements to the current 802.11 Standard to provide Technical Corrections and Clarifications
The rapid adoption of Wi-Fi standards while they’re still in flux means that vendors are building solutions at varying levels of quality.
Do we want to mention the proprietary CCX stuff? There’s also the proprietary nature of some of the feature sets
Some carriers prefer handset with .11a over .11g due to the presence of interference in the 2.4 GHz band
WBA: Wireless Broadband Forum founded by major carriers to address roaming agreements for Wi-Fi
UMA: unlicensed Mobile Access
Candidate proposals for .11n showing in a later slide
HSDPA providing ~ 4.8 Mbps (peak 10-14 Mbps)
Regional area networking (RAN) is a new term
Self forming: a collection of access points to form a coherent & secure home network with minimal user intervention
Three minutes:
Homes with wired networks still outnumbered those homes with wireless networks
33 percent of broadband households have home networks while an additional 5 percent plan to get one
In comparison, only eight percent of dial-up households have home networks with three percent planning to purchase
&lt;number&gt;
LDPC: 800K gates, with 10 to 12 iterations, and &lt; 6 usec @ 240 MHz/540 Mbps, rate ½ to 5/6
Gain about 2 dB over CC
