How can I connect to free wifi hotspots with my laptop?

I’m talking about free wireless in cafes, pubs, parks etc. I have tried once and my laptop said it was connected but it wasn’t. Do I need anything other than the password of the internet service?
My laptop is pretty new, it has wireless lan and everything. At home I connect through wireless router.

You should be able to pick up the wireless network in a cafe or place were WiFi is available as long as you have a wireless card installed in your laptop. Check this website for more information.

Wireless Quality-of-service

Focusing on an important and complicated topic in wireless network design, Wireless Quality of Service: Techniques, Standards, and Applications systematically addresses the quality-of-service (QoS) issues found in many types of popular wireless networks.

In each chapter, the book presents numerous QoS challenges encountered in real-world applications and delineates ways to overcome these obstacles. Some of the challenges explored are performance impairments in WLAN hotspots, video streaming applications, and broadband wireless access. The techniques and mechanisms covered to tackle these problems include medium access and call admission control techniques, a parameter tuning algorithm, the QoS-enabling features of IEEE 802.11e, a Markov chain model, a probe-based distributed admission control mechanism, topology-transparent scheduling protocols, and a novel multicast congestion control mechanism.

Addressing advanced topics and future directions, the expert contributors acknowledge the need for more research to solve several open issues. In the meantime, they offer innovative solutions to solve current QoS problems.

How do I start writing software for mobile phones?

Mobile phones meaning GSM phones, and software meaning application software. I have no clue on how to start writing. i.e languages, SDK, other requirements on my part. I only know the meaning of writing software, but the whole work of converting the ideas in my head to the tangible product is what I don’t know. I think I can learn it if I knew the works. I have ideas about some applications that I would like to try out. Thanks for any suggestions you may be able to give me.
The applications are network applications.

you should have a look at Mobile Processing it involves writing programs in the processing environment, and transferring them onto your phone.

What is the best way to secure your connection at wifi hotspots?

Areas unsecured such as airports, cafes, hotels, etc.

Possible free VPNs or other security software?

The thing about Wi-fi hotspots is they are for the general population, and therefore encryption keys are usually not used and therefore unsecured.

However, the only real reason to secure any wireless connection is because you don’t want others piggy-backing off your network and taking away from you bandwidth.

Just because you are using a wireless connection does not mean you are fully exposed & an easy target for a hacker.
But word to the wise, most hacking is done through acquiring personal information that most people provide quite easily if asked the right way.

Example: Maybe you have a picture of your dog Ralph as your desktop background picture. Then someone strikes up what seems to be polite conversation while you are checking out your portfolio of recent investments. They may say something like, "what a beautiful dog, what’s his name?"
and of course you say "Ralph." Well now this person may have one of the answers to your secret question you setup incase you forget your password. It’s subtle & sneaky; but you’d be surprise how quickly that can equate to a successful hack.

And please, don’t have your badge from work hanging on your rear-view mirror in your car when your not at work. I see it all the time, and just pray these people don’t work in government or something similar.

Good luck and be safe.

technically, what is the difference between CDMA and GSM wireless services?

hi i am a electronics and communication engg student and looking for a fundamental , technical answer please help me out plzzzzzzz ……..people tell me the answer for this

CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code) to allow multiple users to be multiplexed over the same physical channel. By contrast, time division multiple access (TDMA) divides access by time, while frequency-division multiple access (FDMA) divides it by frequency. CDMA is a form of "spread-spectrum" signaling, since the modulated coded signal has a much higher data bandwidth than the data being communicated. An analogy to the problem of multiple access is a room (channel) in which people wish to communicate with each other. To avoid confusion, people could take turns speaking (time division), speak at different pitches (frequency division), or speak in different languages (code division). CDMA is analogous to the last example where people speaking the same language can understand each other, but not other people. Similarly, in radio CDMA, each group of users is given a shared code. Many codes occupy the same channel, but only users associated with a particular code can understand each other.

———————-

GSM is a cellular network, which means that mobile phones connect to it by searching for cells in the immediate vicinity. There are five different cell sizes in a GSM network—macro, micro, pico, femto and umbrella cells. The coverage area of each cell varies according to the implementation environment. Macro cells can be regarded as cells where the base station antenna is installed on a mast or a building above average roof top level. Micro cells are cells whose antenna height is under average roof top level; they are typically used in urban areas. Picocells are small cells whose coverage diameter is a few dozen metres; they are mainly used indoors. Femtocells are cells designed for use in residential or small business environments and connect to the service provider’s network via a broadband internet connection. Umbrella cells are used to cover shadowed regions of smaller cells and fill in gaps in coverage between those cells. Cell horizontal radius varies depending on antenna height, antenna gain and propagation conditions from a couple of hundred meters to several tens of kilometres. The longest distance the GSM specification supports in practical use is 35 kilometres (22 mi). There are also several implementations of the concept of an extended cell[12], where the cell radius could be double or even more, depending on the antenna system, the type of terrain and the timing advance.

Indoor coverage is also supported by GSM and may be achieved by using an indoor picocell base station, or an indoor repeater with distributed indoor antennas fed through power splitters, to deliver the radio signals from an antenna outdoors to the separate indoor distributed antenna system. These are typically deployed when a lot of call capacity is needed indoors; for example, in shopping centers or airports. However, this is not a prerequisite, since indoor coverage is also provided by in-building penetration of the radio signals from any nearby cell.

The modulation used in GSM is Gaussian minimum-shift keying (GMSK), a kind of continuous-phase frequency shift keying. In GMSK, the signal to be modulated onto the carrier is first smoothed with a Gaussian low-pass filter prior to being fed to a frequency modulator, which greatly reduces the interference to neighboring channels (adjacent channel interference).

Proactive Software And The Business Of The Future

The Internet has combined with evolution of corporate data, processes and communications to create the basis for a revolution in corporate organization. Businesses are becoming increasingly modular, doing what they do best and outsourcing the rest. The organization is increasingly turning toward project teams which can be assembled when necessary and dispersed when projects are completed. To facilitate this, procedures and systems are being developed to control and support collaboration. The result? New opportunities for remote workers and virtual offices, with leaner, task focused and ultimately a more efficient organization, essentially unlimited access to resources and personnel around the globe.

The New Office of the Future

At the heart of the new business organization is the virtual business or virtual office. The virtual business can span geographical boundaries and provide instant and flexible collaboration to efficiently develop products and services with minimal supporting overhead. In this “office of the future”, remote workers are linked in a dispersed infrastructure that is supported by software that supports and controls collaboration. Individuals share data and applications over a distance, transmit data of all types easily and efficiently, and the workgroup can meet together to exchange information and views using a variety of different techniques, including videoconferencing, shared whiteboards, teleconferencing, instant messaging, and a variety of asynchronous correspondence and mail capabilities.

Supporting the office of the future is a wide and growing range of collaborative software tools that provide communications, project coordination, data sharing, and application access. The base for this communication is, of course, the Internet, which has been speeding as higher bandwidth technologies are rolled out. These large pipes enhance the opportunities for collaboration.

Always on, anywhere, any time provides the office of the future a number of advantages to both staff and business. To sketch in some of these:

* Any time – flexile working hours, with improved scheduling for business, and more efficient performance from remote workers.

* Any place – flexible work location making it possible to employ people who work at home or in different parts of the country, or even across the globe.

* Any competent task group – flexibility of project staffing, making it possible to make most efficient use of available personnel,

* Wider skill application – particular specialists may contribute to various projects rather than being dedicated to a single operation at one time in one place.

* Amorphous organization – making it possible to create workgroups as needed to handle new projects or new support activities without the upheaval associated with different times and places.

* Scalability and security – incorporating these characteristics in the modular systems and network infrastructure. Modules can be easily grown or combined, and security is integral to both policy and supporting IT infrastructure.

Management Implications

To gain these advantages, the virtual business requires careful planning. Special requirements include:

* A need to keep track of employees’ work, which may not be immediately visible as supervisors may not in the same place or even time zone.

* Need to provide and maintain adequate communications, including sufficient bandwidth for extended communications requirements of collaboration, and special communications tools to support collaborative work without the noise of the communications methods swamping the useful work.

* Tools to support the virtual organization, including communications and management applications. Management requirements are often overlooked, but are the making or the breaking of the virtual organization.

* Implementation of the components of the virtual organization without overspend. This requires careful planning and selection of appropriate systems. There is no one size fits all solution, and whatever infrastructure is working today there will be a need to change and adapted to future both operational requirements and meet today’s budget.

Management is a significant component of this new working environment and helps to bring all of the pieces together. Management tools need to be able to aid in project organization as well as being fitted into the collaboration infrastructure. Coordination applications need to be accessed by all workers on teams and within an organization. Management tools also need to fit organizational budgets and provide sufficient flexibility and scalability to successfully manage projects of varying size and complexity, providing security features to ensure the rules of the collaboration are controlled updated and followed. Distributed infrastructure and application aid collaborations between organisations but bring with them the need to ensure sensitive information can only be accessed by those authorised.

Conclusion

The virtual organization supported by control and collaboration technologies is becoming an increasingly visible phenomenon. As hotter competition forces a higher competitive response on us all it is likely to grow in importance as the performance and cost advantages become increasingly apparent. With lower operational expenses and higher performance on offer few can choose not to consider the option. Management of the virtual organisation is more demanding; it requires effective and accessible support and control tools. ProWorkflow from ProActive Software can help make the virtual organisation a reality for your business.

Compare Mobile Phones: you Have Got the Right

Mobile phones are undoubtedly, one of the better inventions of 21st century with their inimitable technological prowess. Mobile phones have simplified our lives with their endless features. They have redefined communications, mobility and entertainment. They have brought into existence the concept of portable music players and TV’s. Apparently, mobile phones are a vital part of our lives now.

Gone are those days, when it used to be a daunting task to compare mobile phones in terms of looks and features. Now, internet will do this task for you. There are innumerable internet sites catering to this purpose. Mobile review sites and blogs examine each and every handset in terms of features and then give a ranking to handsets, also taking into consideration user’s opinions. Users can complain regarding cranky keypads, low battery lives and poor network services.

Nowadays, a plethora of online mobile shops have also sprung up. To buy a hot gizmo, all you need to do, is to log to any of these shops and you can get a handset at incredibly low rental rates and amazing tariff plans. All the handset makers, whether it’s Nokia, Samsung, Sony Ericsson, LG or Motorola have now made their products available online through different merchants and their affiliates.

Various mobile phone deals are available like contract mobile phone deals and pay-as-you-go deals. You can also get handsets sim-free i.e. without any connection. In contract mobile phone deals, after paying a minimal security deposit, you can enter into a contract with the service provider. Entering into a contract may not be desirable but there are tremendous advantages during the contract period. You can benefit from low network-to-network call rates, free roaming and low call rates. At the end of the contract period, one can comfortably switch to a higher plan. Undoubtedly, contract mobile phone deals are the most convenient way to avail a mobile phone now.

Online mobile sites also offer you the freedom of comparing different deals. You can compare mobile phone deals in terms of incentives offered and the costs. With so many deals, it gets quite confusing to pick the best. Due prudence and adequate knowledge of your own short-term and long-term needs is required for making the right choice.

Ok question about wireless internet, what services are best and how do I do it?

My school has free wireless hot spots and this is all nice but it isn’t very fast when I get on it through my laptop. I want something decently fast for when I’m on the go. I have qwest now through our phone services but it is my dad’s and he just shares it with me through his network. So when I leave my house I can’t use it, my question is…what do I do to get wireless internet outside of my house, what service should I purchase, what’s the cheapest and do I need a wireless card if I am sure I have the wireless card built into my computer already. Any help would be great.
I’ll be traveling all over the city with this computer pretty much and if I need to open it up outside of my son’s day care one day I want to be able to do that, so I will need a service with a great distance range.

Hmm go to local starbucks, get T-Mobile hotspot plan (but you don’t have to, you can also buy prepaid as well). Then register, log on and enjoy service
