In a little over a decade, the Internet has grown from an interesting distraction into an essential part of our lives.

Mobile broadband services let users like reality star Kimberly Stewart keep track of e-mail while on the go.

We can’t go more than an hour without checking e-mail. When we have a question or need more information (about anything), we pop open a Web browser and start Googling. At work, it’s all about videoconferencing, the corporate Intranet and online CRM tools. At home, it’s all about Limewire, YouTube and updating our Facebook page.

The ideal way to access all of these tools and resources is with a broadband (high-speed) Internet connection, something we’ve come to expect at home and at the office. According to 2007 statistics, 70 percent of adult Internet users have broadband at home [source: Pew Internet & American Life Project].

What about when we’re on the move? Surveys show that we still have the same hunger for Internet-based information, communication and entertainment. According to a 2008 report by the Pew Internet & American Life Project, 58 percent of all Americans have used a cell phone or PDA for “non-voice data activities” like sending an e-mail or or recording a video. And 41 percent of all Americans have used a WiFi-enabled laptop computer or other mobile device to access the Internet away from the home or office [source: Pew Internet & American Life Project].

Until recently, there have only been a few options for mobile access to the Internet:

• If you have a WiFi-enabled laptop computer or handheld device, you could check e-mail or surf the Web at free WiFi hotspots in places like airports, coffee shops, bookstores and some downtown areas.
• You could use a WAP (Wireless Application Protocol)-enabled cell phone. WAP is the universal standard for applications using wireless communications.
  
• You could buy a BlackBerry, iPhone or other smartphone to surf special WAP Web sites. But surfing speeds are slow and the Web sites are simple (no video, audio or cool graphics) to access e-mail and the Internet at higher speeds.

Now several major national cell-phone carriers have introduced technology that brings DSL-quality speed to any mobile device within range of a cellular signal, including laptop computers. Some even get bling decal kits for their gadgets.

Mobile Broadband Technology

Mobile broadband is powered by the same technology that makes cell phones work. It’s all about radio waves and frequencies. Cell phones and cell-phone radio towers send packets of digital information back and forth to each other via radio waves. In the case of a phone call, the packets of information carry voice data. For mobile broadband, the packets of information would be other types of data like e-mails, Web pages, music files and streaming video.

With mobile broadband, computer users can surf the Internet and check e-mail from any location, including outside.

There are two basic technologies used to operate cell-phone networks: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). GSM is more popular in Europe and Asia and CDMA is more common in the United States. The major technical differences between the two systems have to do with the way each technology shares space on the radio spectrum. Without getting into the details, both GSM and CDMA use different algorithms that allow multiple cell phone users to share the same radio frequency without interfering with each other.

Mobile broadband is also known as 3G, or third-generation cell-phone technology. Both GSM and CDMA have developed their own 3G technology solutions for delivering high-speed Internet access to mobile devices.

The CDMA-based mobile broadband technology is called EV-DO (Evolution-Data Optimized or Evolution-Data Only). The trick behind EV-DO is that it runs over a part of the cellular network devoted entirely to data. Voice calls require a lot of bandwidth to maintain sound quality. By separating the data channel from the voice channel, the network can maximize data transfers and provide higher-speed access to e-mail, the Internet and multimedia. The downside is that you can’t access the Internet and other data tools when talking on your cell phone. EV-DO advertises average speeds of 300-400 Kbps (kilobytes per second), the equivalent of DSL.

To use an EV-DO network, you need to either have a device that’s already loaded with EV-DO hardware (like a BlackBerry or other smartphone) or a special network card that plugs into your laptop. These network cards connect via USB ports or other standard PC card slots and act as antennas for mobile broadband signals. For the fastest download and upload speeds, you need to be within range of the EV-DO cellular signal. Otherwise, you’ll be bumped down to the 1xRTT (Radio Transfer Technology) standard, which broadcasts at speeds between 60 and 100Kbps.

GSM’s answer to EV-DO is something called HSDPA (High-Speed Downlink Packet Access). Unlike EV-DO, an HSDPA network can handle both voice and data transfers, so you can talk to mom and surf the Web at the same time. It maximizes data transfer speeds by focusing on downloading information, not uploading. HSDPA advertises average download speeds between 400 to 700 Kbps.

Like EV-DO, you’ll need special network hardware to access HSDPA mobile broadband. You either need a device with a built-in HSDPA card or a special PC card that plugs into a laptop computer. You’ll also need to be within range of an HSDPA signal, which is concentrated in metropolitan city centers and along major highways.

Now let’s look at some of the features of mobile broadband service as offered by the large cell-phone providers in the United States. For easy buying we can use payday loan

On 2 November 1988 a 22-year old Cornell University student called Robert Morris released an internet worm capable of exploiting vulnerabilities in the UNIX operating system. It is estimated that it infected 10 percent of the internet including computer spy. Twenty years on, the scale of the malware problem has grown astronomically. Today’s internet attacks are organized and designed to steal information and resources from consumers and corporations. Although there have been instances of attacks driven by politics and religion, the main motivation is fnancial. The web is now the primary route by which cybercriminals infect computers, mainly due to the fact that increasing numbers of organizations have secured their email gateways. As a consequence, cybercriminals are planting malicious code on innocent websites. This code then simply lies in wait and silently infects visiting computers.

The scale of this global criminal operation has reached such proportions that we discover one new infected webpage every 4.5 seconds – 24 hours a day, 365 days a year. Computer spy activities such as spyware, adware, malware are world wide threats. 2008 proved that malware is more than just a Microsoft problem. Although the sheer number of Windows threats far outweighs attacks against any other platform, cybercriminals are turning their attention to other operating systems such as Apple Macintosh, and vulnerable cross-platform software. This seems likely to continue in 2009, with the increasing popularity of portable devices such as the iPhone, iPod Touch, Google Android phone and ultra-mobile netbooks.

2008 computer spy activities

Biggest malware threats – SQL injection attacks against websites and the rise of scareware

New web infections – one new infected webpage discovered by Sophos every 4.5 seconds

Malicious email attachments – fve times more at the end of 2008 than at the beginning

Spam-related webpages – one new webpage discovered by Sophos every 15 seconds

New scareware websites – five identifed every day

Top malware-hosting country – US with 37 percent

Top spam-relaying continent – Asia with 36.6 percent

Amount of business email that is spam – 97 percent

It remains paramount that organizations defend themselves at all levels of their business, not just at the email and web gateways. Networks, desktops, laptops and mobile devices must be comprehensively secured to defend against the myriad threats posed by the criminal underground

This tutorial describes the evolution and technologies involved in broadband media services delivery. A brief history tracing the evolution of broadband media services will be presented, along with descriptions of multimedia standards, potential services, and the roles of the various entities involved in creating broadband media services–network providers, content providers, services providers, and businesses and consumers. After working through the tutorial, participants will have a general understanding of the scope, technology, and benefits of broadband media services.Broadband and bandwidth
“Broadband” refers to a type of network connection that supports a very high bit rate, as opposed to “narrowband,” which supports a lower bit rate. The higher the bit rate, which is a measure of speed of transmission of bits per second (bps), the faster the transmission will occur in a given period of time. “Bandwidth” is a measure of capacity. Greater bandwidth allows more information to be communicated in a given period of time. Broadband media services delivery requires transmitting large amounts of information quickly, so the combination of fast broadband transmissions and large amounts of bandwidth required to deliver information are the foundation of broadband media services delivery. But this is just the beginning of the broadband media services story, because the true value of broadband media services lies in the actual services that can be delivered across these high-speed, high-bandwidth networks, the entirely new “on demand” way customers will access them and the customized and personalized ways that individuals will interact with these services. With that in mind, we can formulate a definition of broadband media services:

Broadband media services is the seamless, customized, “on demand” creation and delivery of multimedia services to homes, businesses, and mobile users, including entertainment services (movies, interactive games, broadcast TV), infotainment (e-learning, online training) through high-speed Internet protocol (IP) networks.

Beyond fast Internet access
“Broadband media” is sometimes called “streaming media” because the services, or “content,” that is delivered via broadband networks is digitized, and received by users of the content in continuous real-time “streams.” Broadband content is digitized and accessed utilizing IP, the standard protocol used for Internet access today. In fact, high-speed IP access through digital subscriber lines (DSL) that utilize existing voice lines for high-speed transmissions, is the foundation of the broadband media services network, and DSL is available in many parts of the world today. DSL is a group of increasingly high-speed technologies that enables fast Internet access in homes and businesses. DSL “always on” connections will also form the basis of the sophisticated broadband media services networks of tomorrow.

Fast Internet access barely scratches the surface of the powers of broadband, DSL, and IP technology, which, combined in broadband media services, will connect people and businesses around the world like never before. Broadband media services will put the consumer in total control by enabling personal, custom, on-demand viewing of entertainment, e-learning, video games, and other types of content. Individuals will choose what they want to hear, see, or be entertained by on their own, and people will no longer have to plan around preconceived broadcast schedules for home entertainment. Eventually, we will decide our own schedules for much of our entertainment. Furthermore, broadband media services will allow individuals to easily create their own content, personalize it, and distribute it for viewing on TVs, PCs, remote laptops, and mobile phones and other wireless devices around the world, instantly.

Broadband media services provides endless possibilities for consumers to choose and personalize their entertainment and infotainment. Broadband media services will also create new revenue streams for operators, media companies, and service providers through enhanced usage of existing networks, branded media portals, interactive “one-to-one” advertising and endless e-commerce possibilities. The proliferation of high-speed broadband IP access and broadband media services will require content creators to distribute large amounts of rich media to a global audience of high-speed users with increasingly greater demand for access to specific services. The challenges for broadband media development include understanding true consumer wants and needs for services and perfecting the technology standards behind the high data rates and significant bandwidth required for seamless delivery of high-quality multimedia services.

When the BlackBerry debuted in 1999, carrying one was a hallmark of powerful executives and savvy technophiles.Most executives that wears ID lanyards might have already own a Blackberry.
People who purchased one either needed or wanted constant access to e-mail, a calendar and a phone. The BlackBerry’s manufacturer, Research in Motion (RIM), reported only 25,000 subscribers in that first year. But since then, its popularity has skyrocketed.

In September 2005, RIM reported 3.65 million subscribers, and users describe being addicted to the devices. The BlackBerry has even brought new slang to the English language. There are words for flirting via BlackBerry (blirting), repetitive motion injuries from too much BlackBerry use (BlackBerry thumb) and unwisely using one’s BlackBerry while intoxicated (drunk-Berrying). While some people credit the BlackBerry with letting them get out of the office and spend time with friends and family, others accuse them of allowing work to infiltrate every moment of free time.

In this article, we’ll examine the “push” technology at the center of the device’s popularity, RIM’s former dispute with patent holder NTP Incorporated and its current dispute with Visto Corporation. We’ll also explore BlackBerry hardware and software.

“Push” Technology

A PDA does a lot of the same things a BlackBerry does, and the PDA made its
debut several years before the BlackBerry. But until recently, the only way to make the information on most PDAs match the
information on a person’s computer was to automatically or manuallysync the PDA. This could be time-consuming and inconvenient. It could also lead to exactly the conflicts that having a PDA is supposed to prevent. For example, a manager might schedule a meeting on the PDA, not knowing that an assistant had just scheduled a meeting for the same time on a networked calendar.

A BlackBerry, on the other hand, does everything a PDA can do, and it syncs itself continually throughpush technology. BlackBerry Enterprise Server or Desktop Redirector software “pushes,” or redirects, new e-mail, calendar updates, documents and other data straight to the user over the Internet and the cell phone network.

First, the software senses that a new message has arrived or the data has changed. Then, it compresses, packages and redirects the information to the handheld unit. The server uses hypertext transfer protocol (HTTP) and transmission control protocol (TCP) to communicate with the handhelds. It also encrypts the data with triple data encryption standard (DES) or advanced encryption standard (AES).

A person can send and receive messages and phone calls on a BlackBerry from virtually any location.

The software determines the capabilities of the BlackBerry and lets people establish criteria for the information they want to have delivered. The criteria can include message type and size, specific senders and updates to specific programs or databases.

Once all of the parameters have been set, the software waits for updated content. When a new message or other data arrives, the software formats the information for transmission to and display on the BlackBerry. It packages e-mail messages into a kind of electronic envelope so the user can decide whether to open or retrieve the rest of the message.

The BlackBerry listens for new information and notifies the user when it arrives by vibrating, changing an icon on the screen or turning on a light. The BlackBerry does not poll the server to look for updates. It simply waits for the update to arrive and notifies the user when it does. With e-mail, a copy of each message also goes to the user’s inbox on the computer, but the e-mail client can mark the message as read once the user reads it on the BlackBerry.

People describe BlackBerry use as an addiction, and this is why. Not only do they give people constant access to their phones, they also provide continual updates to e-mail, calendars and other tools.

Lately, RIM had been dealing with issues of patent infringement.

People compose e-mail on a BlackBerry using a QWERTY keyboard and typing with their thumbs. Unfortunately, the BlackBerry’s e-mail capabilities are the focus of a patent dispute.
