Ten Technologies That Will Rock 2010

Below is my list of the ten technologies that will leave the biggest marks on 2010:

1.The Tablet: It’s the most anticipated product of the year. The mythical tablet computer (which everyone seems to be working on). There are beautiful Android tablets, concept tablets, and, of course, the one tablet which could define the category, the Apple Tablet. Or iSlate or whatever it’s called. If Steve Jobs is not working on a tablet, he’d better come up with one because anything else will be a huge disappointment.Why do we need yet another computer in between a laptop and an iPhone? We won’t really know until we have it. But the answer lies in the fact that increasingly the Web is all you need. As all of our apps and data and social lives move to the Web, the Tablet is the incarnation of the Web in device form, stripped down to its essentials. It will also be a superior e-reader for digital books, newspapers, and magazines, and a portable Web TV.
2.Geo: The combination of GPS chips in mobile phones, social networks, and increasingly innovative mobile apps means that geolocation is increasingly becoming a necessary feature for any killer app. I’m not just talking about social broadcasting apps like Foursquare and Gowalla. The advent of Geo APIs from Twitter , SimpleGeo, and hopefully Facebook will change the game by adding rich layers of geo-related data to all sorts of apps. Twitter just recently launched its own Geo API for Twitter apps and acquired Mixer Labs, which created the GeoAPI.
3.Realtime Search: After licensing realtime data streams from Twitter, Facebook, MySpace, and others, Google and Bing are quickly ramping up their realtime search. But realtime search is still treated as a silo, and is not regularly surfaced in the main search results page. In 2010, I expect that to change as the search engines learn for what types of searches it makes sense to show Tweets and other realtime updates. In the meantime, a gaggle of realtime search startups such as Collecta, OneRiot, and Topsy will continue to push the ball forward on the realtime search experience. Realtime search will also become a form of navigation, especially on Twitter and Facebook. The key will be to combine realtime search with realtime filters so that people are delivered not only the most recent information but the most relevant and authoritative as well.
4.Chrome OS: In November, Google gave the world a sneak peek at its Chrome operating system, which is expected to be released later this year. The Chrome OS is Google’s most direct attack on Windows with an OS built from the ground up to run Web apps fast and furious. Already a Google is rumored to be working on a Chrome Netbook which will show the world what is possible with it a “Web OS.” It sounds like it would be perfect for Tablet computers also (see above). Chrome is a risky bet for Google, but it is also potentially disruptive.
5.HTML5: The Web is built on HTML (Hypertext Markup Language) and the next version which has been taking form for a while is HTML5. Already browsers such as Firefox and Google’s Chrome (the browser, not the OS) are HTML5-friendly. Once HTML5 becomes more widespread across the Web, it will reduce the need for Flash or Silverlight plug-ins to view videos, animations, or other rich applications. They will all just be Web-native. HTML5 also supports offline data storage, drag-and-drop, and other features which can make Web apps act more like desktop apps. A lot of Websites will be putting HTML5 under the hood in 2010.
6.Mobile Video: With video cameras integrated into the latest iPhone 3GS and other Web phones, live video streaming apps are becoming more commonplace—both streaming from phones and to them. As mobile data networks beef up their 3G bandwidth and even start to tiptoe into true broadband with 4G (which Verizon is heading towards with its next-gen LTE network), mobile video usage will take off.
7.Augmented Reality: One of the coolest ways to use the camera lens on a mobile phone is with the increasing array of augmented reality apps. They add a layer of data to reality by placing everything from photos to Tweets to business listings directly on top of the live live image captured by the camera. Tonchidot’s Sekai Camera, Layar, GraffitiGeo and even Yelp are examples of augmented reality apps.
8.Mobile Transactions: As mobile phones become full-fledged computers, they can be used for mobile commerce also. One area poised to take off in 2010 are mobile payments and transactions. Twitter founder Jack Dorsey’s latest startup Square turns the iPhone into a credit card reader. Verifone has its competing product, as does Mophie. The idea is that any mobile phone can become a point of sale, and those mobile transactions can tie into back-end accounting, CRM, and other enterprise systems.
9.Android: Last year saw the launch of nearly two dozen Android-powered phones, including the Verizon Droid. In a few days, Google’s Nexus One will launch as the first Android phone which can be unlocked from any given carrier (it is launching with T-Mobile). Android is Google’s answer to the iPhone, and as it reaches critical mass across multiple carriers and handsets it is becoming increasingly attractive to developers. There are already more than 10,000 apps on Android, next year there will be even more. And other devices running on the mobile OS are launching as well.
10.Social CRM: We’ve seen the rise of Twitter and Facebook as social communication tools. This year, those modes of realtime communication will find their way deeper into the enterprise. Salesforce.com is set to launch Chatter, it’s realtime stream of enterprise data which interfaces with Twitter and Facebook and turn them into business tools. Startups like Yammer and Bantam Live are also making business more social.

Raman Amplifiers

Amplifiers based on Raman gain, which results from the effect of stimulated Raman scattering.

The Raman-active medium is usually an optical fiber, although it can also be a bulk crystal, or a cell with a gas or liquid medium. An input signal can be amplified while co- or counterpropagating with a pump beam, the wavelength of which is typically a few tens of nanometers shorter. For silica fibers, maximum gain is obtained for a frequency offset of 10–15 THz between pump and signal, depending on the core composition.

Source:www.timbercon.com/Raman-Amplifiers.html

Raman amplifier

A type of amplifier used in long haul, single-mode (SMF) fiber optic transmission systems (FOTS). Raman amplification usually occurs throughout the length of the transmission fiber itself in a process known as distributed amplification, rather than in a discrete amplification, or lumped amplification configuration such as that employed by an erbium-doped fiber amplifier (EDFA). Raman amplification occurs as a high-energy pump wavelength is sent in the reverse direction from the output end of the fiber span, where the incoming signal is weakest. The pump wavelength, which generally is in the 1450 nm range (E-Band), interacts with and excites atoms in the crystalline lattice of the fiber core.The atoms absorb the photons, and quickly release photons with energy equal to the original photon, plus or minus atomic vibration. In other words, a frequency/wavelength shift occurs as the pump wavelength propagates along the fiber in the reverse direction.The energy lost in the pump wavelength shifts to longer-wavelength (within about 100 nm) signals, generally in the 1550 nm window (C-Band), in the forward direction, thereby serving to amplify them. Raman amplifiers offer the advantage of amplifying signals in the broad range extending from 1300 nm to 1700 nm. Further, they perform better than EDFAs in terms of signalto-noise ratio (SNR). Raman amplifiers often are used as preamplifiers to enhance the performance of EDFAs in dense wavelength division multiplexing (DWDM) systems.

Raman Amplifier

A Raman optical amplifier is not a "black box" like an EDFA. It consists of little more than a high-power pump laser, usually called a Raman laser, and a WDM or directional coupler. The optical amplification occurs in the transmission fiber itself. The optical amplification is distributed along the transmission line. Optical signals are amplified up to 10 dB in the network optical-fiber. The Raman optical amplifiers have wide gain bandwidth (up to 100 nm). They can use any installed transmission optical-fiber (single-mode optical fiber, TrueWave, etc.). In effect, they reduce the effective span loss and improve noise performance of the transmission line by boosting the optical signal in transit. They can be combined with erbium-doped fiber amplifiers (EDFA) to achieve very wide optical gain flattened bandwidth. Figure 3 shows the topology of a typical Raman optical amplifier. The two key elements of the Raman optical amplifier are the pump laser and the directional coupler. The pump laser, in this case, has a wavelength of 1535 nm. The circulator provides a convenient means of injecting light backwards in to the transmission path with minimal optical loss.
shows the optical spectrum of a forward-pumped Raman optical amplifier. In this case, the pump laser is injected at the transmit end rather than the receive end as shown in Figure 3. The pump laser has a wavelength of 1535 nm. As is usually the case, the amplitude of the pump laser is much greater than the data signals. Figure 5 shows the received signal after the same length of fiber used in the SRS example above. While the amplitude of the pump laser is significantly decreased, the amplitude of the six data signals is now much stronger and they all have roughly equal amplitudes. In this case, a great deal of energy was robbed from the 1535 nm pump laser signal and redistributed to the six data signals.

IMS Architecture

The IP-Multimedia Subsystem (IMS) defines the functional architecture for a managed IP-based network. It aims to provide a means for carriers to create an open, standards-based network that delivers integrated multimedia services to increase revenue, while also reducing network CapEx and OpEx.

IMS was originally designed for third-generation mobile phones, but it has already been extended to handle access from WiFi networks, and is continuing to be extended into an access-independent platform for service delivery, including broadband fixed-line access. It promises to provide seamless roaming between mobile, public WiFi and private networks for a wide range of services and devices.

The IMS architecture has been designed to enable operators to provide a wide range of real-time, packet-based services and to track their use in a way that allows both traditional time-based charging as well as packet and service-based charging. It has become increasingly popular both with wireline and wireless service providers as it is designed to increase carrier revenues, deliver integrated multimedia services, and create an open, standards-based network.

IMS provides a wide range of session border control, including call access control, reachability and security. It also provides a framework for the deployment of both basic calling services and enhanced services, including

•multimedia messaging
•web integration
•presence-based services
•push-to-talk.
At the same time, it draws on the traditional telecommunications experience of

•guaranteed QoS
•flexible charging mechanisms (time-based, call-collect, premium rates)
•lawful intercept legislation compliance.
Network operators also hope that IMS will cut their CapEx and OpEx through the use of a converged IP backbone and the open IMS architecture.

•The IMS architecture defines many common components (for example, call control and configuration storage) so less development work is required to create a new service as this existing infrastructure can be reused.
•The use of standardized interfaces should increase competition between suppliers; preventing operators from being locked into a single supplier's proprietary interfaces.
As a result, IMS should enable new services to be rolled out more quickly and cheaply, compared with the traditional monolithic design of telephony services

IP Multimedia Subsystem (IMS)

IP Multimedia Subsystem (IMS) is a generic architecture for offering multimedia and voice over IP services, defined by 3rd Generation Partnership Project (3GPP). IMS is access independant as it supports multiple access types including GSM, WCDMA, CDMA2000, WLAN, Wireline broadband and other packet data applications. IMS will make Internet technologies, such as web browsing, e-mail, instant messaging and video conferencing available to everyone from any location. It is also intended to allow operators to introduce new services, such as web browsing, WAP and MMS, at the top level of their packet-switched networks

IP Multimedia Subsystem is standardized reference architecture. IMS consists of session control, connection control and an applications services framework along with subscriber and services data. It enables new converged voice and data services, while allowing for the interoperability of these converged services between internet and cellular subscribers. IMS uses open standard IP protocols, defined by the IETF. So users will be able to execute all their services when roaming as well as from their home networks. So, a multimedia session between two IMS users, between an IMS user and a user on the Internet, and between two users on the Internet is established using exactly the same protocol. Moreover, the interfaces for service developers are also based on IP protocols.

Some of the possible applications where IMS can be used are:

•Presence services

•Full Duplex Video Telephony

•Instant messaging

•Unified messaging

•Multimedia advertising

•Multiparty gaming

•Videostreaming

•Web/Audio/Video Conferencing

•Push-to services, such as push-to-talk, push-to-view, push-to-video



Effectively, IMS provides a unified architecture that supports a wide range of IP-based services over both packet- and circuit-switched networks, employing a range of different wireless and fixed access technologies. A user could, for example, pay for and download a video clip to a chosen mobile or fixed device and subsequently use some of this material to create a multimedia message for delivery to friends on many different networks. A single IMS presence-and-availability engine could track a user's presence and availability across mobile, fixed, and broadband networks, or a user could maintain a single integrated contact list for all types of communications.

A key point of IMS is that it is intended as an open-systems architecture: Services are created and delivered by a wide range of highly distributed systems (real-time and non-real-time, possibly owned by different parties) cooperating with each other. It is a different approach to the more traditional telco architecture of a set of specific network elements implemented as a single telco-controlled infrastructure.

Voice Changer Software – Customize the voice as you need

The technology we have today already created many tools that really helps our daily activities, for example, the Internet. When we don’t have an Internet, we often use post office to send all of our letters or documents that will need days, weeks, or even months to arrive.

However, with the help of Internet, we could send the same documents faster and cheaper, even free! This is why technology is really important for our live.

Voice changers are one of the technologies that start rising today. You probably already saw them in the movie, especially the one in Mission Impossible 3. Who could have realized before that most of the technologies we found today starting from an idea? Nobody would really dream of one day that we could be holding realtime conferencing with our counterpart who are sitting in their room , and conducting business meeting via teleconference technology ! The idea that keeps bugging in the head, with a good execution will make it a worthy product.

3G Tutorial

Original 3G Tutorial – January 2003

By Brough Turner and Marc Orange, NMS Communications

You may download our complete 120+ slide tutorial on 3rd Generation Mobile Wireless Systems, in PDF (2 MB) or PowerPoint *(6 MB) formats. This comprehensive slide set on 3G communications will benefit both the technical and general telecom audience. The tutorial reviews the history and evolution of mobile radio, evolving network architectures, services, applications, and business models. Alternative 3G paths and potential for convergence in the evolving network are reviewed in detail.

*NOTE: The PowerPoint version is roughly three times as large as the PDF version, and requires Microsoft PowerPoint to display. The advantage of the PowerPoint version, however, is that many of the graphical slides "build" on consecutive keystrokes, illustrating message flows or the evolution of network architectures.

Here is an outline of the slide set:

A brief history of cellular mobile telephony
The 3G vision and variants that are included within "3G"
2G and 3G radio technologies and how today's systems evolve to 3G
Core network architectures and their evolution to 3G
The potential for global roaming
New applications and application frameworks
Business models: what's really happening and how is the 3G vision likely to unfold?
Evolving services in 2.5G and 3G: SMS, EMS, MMS Messaging; location and presence; video and IP multimedia
