Anywhere Computing Opens Endless Possibilities …

Increasingly, it’s getting tougher for people to throw their computers out the window when they encounter a gottcha' because they may already be outside. The rapid spread of the new public wireless networks is keeping people plugged in without being plugged in.

Wireless hot spots or nodes are popping up everywhere – coffee shops, libraries, bookstores, airport lounges and even parks. Affectionately called Wi-Fi, it is helping boost notebook and hand-held organizer sales. Technically, the wireless networks are based on IEEE 802.11 (a, b or g) standards.

Looking like a standard PCMCIA memory card – but with a loop antenna – the Wi-Fi cards slip easily into the computer’s card slot and will automatically find a nearby wireless node. If you have difficulty locating an access node, free “sniffer” software programs are available to find all nearby networks. Then, you can choose the one you want to connect with.

Open Environment
The same open spirit that started the original Internet more than 10 years ago is rapidly building out the nation’s Wi-Fi network. User groups, companies, retailers (theaters, coffee shops, restaurants, malls) as well as governmental and educational agencies are adding nodes in stores, parks, public buildings.

The high-speed wireless network (top speed of 11 Mbps with higher speeds in the wings) is either free or relatively inexpensive and delivers data to your system much more rapidly than dialup, DSL or cable modems. Obviously, the trend for wireless connectivity is also attracting service providers – Boingo Wireless and T-Mobile are among the earliest and most widely known.

The fact that the gratis sites are as open to you as to anyone else means it can be relatively easy for less than scrupulous individuals to “borrow” your passwords, credit card information and other vital data. For the majority of your work or activity, this is of little concern. When it is, tap into one of the subscription services that deliver some level of security (it is getting better). New virtual private network (VPN) software encrypts your communications, making it difficult to hack as it mixes with the other traffic on the Web.

While we don’t expect the free ride wireless service to last forever (someone is paying for the Internet connection you share), it will always be price-competitive--especially considering the speed of sending/receiving data.

Whether you choose the free route, a more secure subscription service or a combination of the two; wireless on-the-go computing is changing almost everything about the way we conduct business or simply stay in touch.

Stimulates System Sales
For computer manufacturers, integrators and resellers the Wi-Fi phenomenon has produced the one bright spot on the PC sales landscape. The rapid delivery of high bandwidth, security and quality-of-service makes it enticing to mere mortals.

It is also creating a new area of concern with corporate and IT managers.

The problem is that with higher-performance CPUs and larger storage capacities, the laptop and notebook computer are rapidly becoming users' primary computer, rather than just their on-the-road supplement. At first blush, that sounds good because users can have instant access to the most current information, regardless of their location – in the office, in the conference room, at home, in the airport, in their hotel room or in a client’s office.

The problem – and the operative words are, "current information."

Areas of Concern
Contingency Planning Research points out the obvious:
- There has been a dramatic increase in the volume of data stored on PCs (even in the corporate office environment). Because of the extremely low cost, storage capacity has increased 80 percent over the past 12 months and will increase more than 50 percent in the coming 12 months.
- Corporate users have traditionally resisted hierarchical storage management (HSM), preferring to retain “their” data on their systems. Forty percent of corporate users resist or circumvent centralized storage.
- Less than 30 percent of all PC users backup their data
- The Internet has opened systems to the world, meaning that any and all data is available to others.
- Thirty-one percent of users are susceptible to virus attacks and 56 percent are vulnerable to exposing private data online.
- Even users that utilize virus protection software are only protected from existing viruses. There is no protection for new viruses which usually require 2-3 days for antivirus firms to research and block.

If you feel this is discouraging, consider the notebook or laptop computer user:
- Notebook and laptop computers are five times more likely to be stolen than desktop systems. The IRS lost or misplaced more than 2300 laptop computers over the last three years.
- Fifteen percent of all laptops are stolen every year.
- Because of heightened airport security, the number of laptop and notebook computers lost, misplaced, stolen or forgotten at airports has increased more than 80 percent in the past 12 months.
- Notebook hard drives are 10 times more likely to crash than desktop systems.
- Today, an organization’s most current customer data is in the field – not in the office – the cost of manual recovery is prohibitive.

While insurance can be purchased for the replacement of notebook or laptop hardware, there is no insurance that can replace the data.

Added Care, Protection
Users need to understand that these mobile systems aren’t invisible, nor are they invincible. While it is impossible, we would almost recommend that anyone who receives a portable computer also receives an orientation on how and why they need to protect the corporate data they will be carrying with them around the country and the globe. Any portable PC can be configured to require a password before the user can access any data on the system. This ensures at least some data protection.

To protect users from virus-inflicted disasters, the leading PC antivirus firms have automated their products so that scheduled updates are carried out without the user’s intervention.

While these steps do protect the systems from outside theft or attack, they do not protect the individual's and the organization's most valuable asset – the data. There's simply no substitute for an economical and reliable backup and disaster recovery solution that will protect the individual’s and organization’s most valuable asset and is easy to use!

Tailor Protection
Only full, incremental and differential backup scheduling can protect vital information from the top mobile PC disasters.





New automated backup solutions are available that provide both drive image and file backup. With convenient features such as the ability to exclude and include files, users can bypass or select specific file types from multiple folders for backup. Advanced solutions such as NTI’s Backup NOW! enable unattended backup across multiple drives and multiple media.

The advanced solutions also incorporate the ability to produce a bootable disc for fast, reliable disaster recovery.


Traditionally, backup software only backed up hard drives to tape. The new breed of software backs up mission-critical data to virtually any medium – tape, MO, USB pen drives, Zip, Jaz, floppy, DVD, CD and even other hard drives. In addition, advances have been made to allow users to carry out backup across multiple media or multiple discs.

Since CD writers are generic to almost every notebook and laptop computer (internal or external), and the media is almost as economical as paper, CDs provide an excellent backup and recovery medium for mobile users.

For best protection, incremental or differential backups backup should be carried out on a daily basis and full backups should be made at least every other week.

A World of Ifs
Some users only focus on the incremental or differential backups. This would be fine if your hard drive never crashed, if viruses never worked their way into your OS and application software or if… Most people forget that it can take hours to reinstall the OS and all of their applications. Returning your settings and configuration (forget about the raw data) to its previous condition can take days…weeks…and will probably never be quite the same.

Once you have made your latest CD full backup, put these discs in your suitcase when you travel (obviously, the backup in the bag with your portable PC is of little assistance if the bag is stolen). Data recovery specialists often recommend that you keep 2-3 sets of your backups with you. The newest in the suitcase with your clothes, the next older in another safe travel location and the oldest with your computer.

Looking at the various backup disc sets, it may look like paranoid overkill until you lose or have your notebook/laptop stolen, the hard drive crashes or a very persistent virus corrupts your entire system. With any luck at all, you will never have to use the sets of older backups and can reconstruct your system in almost no time, except for the most current data. Usually, the amount of lost data is less than 2-4 MB – a difficult but “tolerable” loss compared to attempting to recover 10-30GB of files.

Rapid Mobile Growth
Wi-Fi usage is becoming increasingly popular (Gartner Group estimates that usage will grow to more than 1.9 million in 2003, up from 700,000 in 2002) as hot spots triple across the country. Today, there are about 3,300 nodes in the U.S. Individual and corporate users will find it even more attractive as next-generation 54G versions (54 Mbps, 5X faster than current Wi-Fi speeds) become more widely available and the set up for each new location becomes faster and easier.

Quality of service (QoS) was a major concern during the early days of the Internet and is for the most part a non-issue. The same holds true for Wi-Fi connectivity. Communication security options are readily available and appear to work extremely well. The weakest link in the protection of data continues to be the human factor.

As people increasingly extend their working environment to parks, coffee shops and airport lounges; IT management will have to focus more of their attention on helping people understand that they are carrying the company’s most valuable resource with them. Mobile users need provide the same level of protection to the notebook-stored data that they would give a company-private file folders they would lock in their desk drawer.

New backup/recovery software automates much of the protection process. Used in conjunction with CD writers and CD media, the software provides the added level of data protection people need as they extend their work hours and work environments.

Planning your backup and disaster recovery program just as you get up to leave Starbucks and watch your notebook PC slip from your hands after eating a croissant will be a little late. Fortunately, there are firms that specialize in recovering data from a damaged system. It only takes time and money.

Today’s new backup/recovery software, combined with your notebook or laptop CD writer, can make data protection as natural as a second cup of coffee.

Re: your personality type? - Hi Michelle! If you are the present-moment focused, this is your result. If it doesn't seem spot on, I'll give you the big-picture focused result. The Enjoyer of Life. You enthusiastically enjoy experiencing the five senses, creative pursuits and social harmony in the here-and-now. You are independent, socially upbeat, and enjoy creating a positive and happy atmosphere. Despite your outgoing “persona,” you are a private person and few people truly know you well). #1 Strength: Comfort Creator #2 Strength: Expressing Social Feeling 1) Comfort Creator -- Creating a comfortable physical environment. Feels the ?ve senses vividly. Adept at using objects, or ?nding or building objects, to make a physical space the most soothing to all ?ve senses. Also organizing so objects are easily found in a convenient way. Both the physical comfort of self, and others, is important. Often feel a need to ensure those close to them are warm enough, fed, rested, etc. Will easily offer help to others in these areas, lending a jacket, or offering a snack. 2) Expressing Social Feeling Setting an emotional tone, vibrant, energetic, or serious, etc. Concerned with the emotional environment as it?s happening -- the vibe of people at a party, the tone of a situation, other people?s responses. Setting the tone -- dramatic and serious, or lighthearted and a celebration. Emotional displays are important for knowing how others are feeling, whether bad or good. Someone talking in a monotone about feelings seems insincere. Feels should be shown, so they can be read by others. Your best type would be: The Conceptualizer. You are an inventive creator of logical systems of possibilities that you use to create processes, products or strategies.

Outsourcing Increased My Productivitiy By 200% - Recently I’ve been testing some new ideas with “outsourcing” for Internet Business Path and from what I can gather, it’s been able to increase my productivity by at least 200%. What I did before outsourcing work to people was to create a mindmap of what the business needed in order to grow and continue to run without my input. Below is the mindmap of my businesses in it’s simplest form: IBP Mindmap If want to create one, a really good software to use is FreeMind. It’s very easy to learn and very powerful for any business because it allows a business owner to laid down their ideas in a logical path. Since applying a mindmap to my business I’ve been able to design the system to increase my productivity by 200%. How Do I Outsource If I Don’t Have The Money? Firstly let me say, if you don’t have the money to afford $3 - $5US an hour to pay someone to handle your tasks that needs to be done repetitively, then you shouldn’t be in business. Okay, I’ll be fair and tell you this: I had the mindset previously to do everything myself because it was always about not having enough money. I know how you feel when you first start running an Internet business or is still a one man show, but it’s having the courage to step out of your comfort zone and learn to delegate tasks to other people to do. It’s not going to be perfect at the beginning, but with a little training, some trial and error and time you will be able to leverage your time and increase your productivity. Outsourcing Administrative Tasks An example that I’ve been able to outsource for $3 US an hour is the ability to get my virtual assistant to check and reply to customer service emails every second working day. Provided that I have given the guidelines and information for how to respond, I have eliminated at least 10 hours a week of my time that I used to spend replying and following up emails. When you think about it, it only costs me around $30 US for a virtual assistant to free up 10 hours of my week. Isn’t that worth the trade off when my time is worth $500 per hour? There are many other examples I could give you on how to outsource your work, you can read more of it in my Internet Business Blueprint report. A Web Developer Will Solve All Your Website Issues If you’ve read my business timeline, you would know that I graduated with a Computer Science degree from UNSW. Even with a degree in Computing Science I’m still not a good programmer and I choose not to be. I would rather leave the technical issues for a web developer that I can hire on an ongoing basis and pay them to work on my projects. It would take them a couple of hours to do something that would take me all week. Hence the websites I design and this blog you are reading has been designed by a web developer I hire and I simply project manage the process to achieve a great result for my clients. A Bookkeeper Will Keep The Tax Office Happy If you’re like me and hate seeing piles of invoices and accounts unreconciled, then I know you would hate book keeping. It’s a crucial part of your Internet business and without it there’s no way to measure how well your business finances are doing. There are systems that allow you to keep track of your business online, but not all of them are compatible with the tax laws within your country. Therefore I still purchase accounting software that is meeting Australian standards, such as MYOB Accounting. I hire a book keeper to help make sure my accounts are up to date and to generate reports to show me the financial health of the business. I hire a book keeper on a monthly basis where I can have all my paper work batched and she will enter the information at one time. She makes sure that my books are up to date and tax is paid on time and I don’t get calls from the tax office. She would save at least 20 hours + a month of book keeping that I would have had to do myself, all for the cost of a dinner with my partner. I’m Still The Writer And Internet Marketer I love writing and expressing my ideas on Internet Business Path and will continue to do so for a very long time. I found that it’s a great way to communicate with people from all over the world and I love receiving feedback and comments. I do this because I’m passionate about Internet business and if you know me I usually share my ideas with my friends and family most of the time. I could outsource the writing to a ghostwriter quite easily and let someone else do the marketing, though I have learnt that these are my strengths and communicating and promoting my business is my passion.
