There are simply too many generic Wi-Fi tips suggesting that if you are having trouble getting an acceptable Wi-Fi signal, you need to move closer to the access point. Of course, this is the most obvious and the most affordable solution. But, often you pretty much stuck on your location or you don’t want to look silly by moving randomly while pointing your notebook to all direction. The real answer is by improving the range of your notebook. 

Enhanced-capability notebook adapters will go a long way toward solving the dilemma of being too far away from a signal source. You can use these devices to improve your chance of connecting a hotspot with your notebook at a longer distance. Before rushing right out to buy all the parts and pieces necessary, give external Wi-Fi adapters a good and thorough test. If you are still facing problems obtaining a steady connection, then you should go back and try one of these ways to extend the Wi-Fi radio-transceiver range:

Improving antenna gain: If you have bought one of those Wi-Fi adapters that use a removable antenna, then you need to get a high-gain antenna. Most external Wi-Fi adapters come with an antenna that is rated at approximately 2 dB – but even those that already have high-gain antennas will do better when connected with a dedicated external high-gain antenna.

There are a couple of types of external high-gain antennas, directional and omnidirectional:

The difference between directional and omnidirectional antennas is just like comparing a lantern and a lantern (respectively).  A lantern casts its light in all directions; a flashlight concentrates its light as a single narrow beam. Many antennas are basically omnidirectional to maximize coverage and reach moving devices. The term antenna gain essentially refers to the signal focus. A high gain antenna emits a tightly focused field; while a low-gain antenna emits a widely focused field. A high-gain antenna, therefore, is not actually more powerful than a low-gain antenna. As a matter of fact, there is really no signal output increase in a high-gain antenna – it is just that the signal is more focused.

Output amplification: If you have found that a high-performance 200 mW notebook adapter does not quite cut the mustard (or if you are just plain power-hungry), there are a few wireless amplifiers that offer power output until up to 1000 mW (1 Watt).  Never try to amplify a high-output external adapter. You will only fry the amplifier. An amplifier is designed to support the input power of a typical wireless adapter -approximately between 32 mW to 63 mW.

Combining high-gain antenna and amplified output: By far the most effective configuration for extending the Wi-Fi range is by combining a high-gain antenna and high-output amplifier. You’ll be pleased to know that several manufacturers sell complete Wi-Fi extension kits that include the high-gain antenna, the amplifier, and an adapter.

All anti-spam solutions should give you a basic feature of blocking bad e-mails. However, increasingly better spam attack techniques force us to continuously improve the anti-spam solution capabilties. Here are 4 key features that should be used to counter future spam attacks.

1. Administration of underlying OS: Relevant only for software-based solutions. Whether when using Windows or UNIX, someone will need to spend some time updating the operating system: making configuration changes, installing patches from time to time, and tracking resource performance and consumption.
2. Enterprise policy administration: When using centralized spam blockers, whether it is a software-, appliance-, or ASP-based system, will require certain amount of organization-level administration, including quarantine management and white-list management for adjusting the degree of filtering, should too few or too many messages are tagged as spam.
3. Performance upgrades monitoring: As the company and/or the e-mail capacity grows, someone has to watch resource utilizations over time so that an upgrade to network capacity and server hardware can yield better results
4. Automatic algorithm and signature updates: In order to stay completely effective, an anti-spam solution must have the most recent rules (ways to determine whether an e-mail is spam or not) and signatures (characteristics of all known spam messages). Spam filters do this by periodically downloading and installing updates from the spam filter’s website. Someone must watch this diligently to make sure that the updates work properly.

Apple launched its disappointing and, arguably, flawed iPad and yet all of a sudden everyone is piling on the “anti netbook” bandwagon. The netbook’s days are numbered, claims an expert. The iPad is killing the netbook, says another.

It’s like a huge chunk of the IT industry decided to temporarily shelve their respective intellects and allow themselves to be swayed by Steve Jobs’ words. However, avid netbook users tend to think the iPad is less flexible and less functional than a netbook, and worse it comes with a long laundry list of missing features and compromises.

Multitasking: Of course, iPad can multi-task, a limited multi- tasking and reserved only for its native apps. It’s not a complete multi-tasking power for opening and switching between dozens of 3rd party applications. By multitasking, you can do a lot more in a single device. For example, with a typical $375 netbook (Intel Atom and WIndows XP Home), you can do your works with your word processing software while downloading a virus definition update and playing a song in the background. And after you finish your works, you can unwind by blasting some Nazis in the oldie-but-goodie Call of Duty 1. Throw in a 3rd-party video chat (oh no, the iPad doesn’t have a camera right?) while playing multiplayer games and we are already way beyond what even the most expensive iPad model can do.

Media support: After installing the necessary codecs, netbooks can support all media formats, from any conceivable sources. With a 10″ and 16:9 aspect ratio screen, you can enjoy HD-formatted videos in all its borderless glory. For those who hunger for more, they can bring new media contents into the netbook via a wide range of well-supported conduits: USB, gigabit Ethernet, Wi-Fi, media card reader, and so forth. With iPad, you have iTunes and well, that’s about it.

Connectivity: A typical netbook comes with bristles of connectivity options, USB, Ethernet, Bluetooth, Wi-Fi and many more. In addition, even a cheap netbook is equipped with an ExpressCard slot and 8-in-1 media card reader. You can also get HSDPA connectivity easily by buying a 3G adapter. By contrast, Jobs’ new tablet is just a wireless-only device, and the absence of a built-in USB port or media card reader really hamstrings its users.

Mobility: Thanks to their compact size and weight, people can set netbooks down on nearly any surfaces, including their laps, and type away comfortably. You never need to worry about stabilizing it or propping it up while you are on a moving train, taxi, or bus. It is about as close to mobility flawlessness as you can experience. With iPad you are wasting one hand only for holding it. A few newer netbook models are now using  touch-screen display, which improve its versatility (Windows-based netbook/tablet convertible Asus Eee PC T91 with touchscreen display is only $445 on Amazon).

In the long run, it’s doubtful that most netbook users will ditch their netbooks in favor of an iPad. For netbook fanatics, the new tablet is missing a lot of useful features and just a jumble of ill-conceived ergonomics design while offering netbook owners nothing in the way of versatility and real innovation; instead, it forces consumers to discard functionality and features in order to squeeze the whole thing into very restrictive confines.

It is actually possible that introduction of the iPad could boost netbook sales as consumers revisit the market for “more flexible” solutions and find that an ideal gadget had sit there all along between the traditional notebook and the smartphone.

Yes, it’s a netbook and Apple doesn’t have it.

Sony, the pioneer of innovative ideas, has always been a boon to the world of music and its fans all over the nations. The concept of enjoying music, sitting in one place, by listening to the music that came from big transistors and radios was revolutionized for the first time when Sony brought to the limelight their walkmans. The walkmans enhanced music with moves!

Sony has till now released a series of walkmans, which the global population has always very well followed. The good news, which has turned to be the talk of the town, is that Sony has made a very recent launch of a walkman- Sony Walkman A845, the new born boon to the world of symphony. Sony Walkman A845 is indeed one of the most exciting launches that Sony has ever made. It is acknowledged to be the slimmest walkman produced ever in the history of walkmans.

Sony A845 Walkman has several cool features to boast of, in its list. The main feature of the walkman is its audio that is delivered in a manner that is unmatched for definite. The player employs the S – Master Digital Amplifier, which account much for the great quality that the audio delivered has to speak of. A combination of both the S – Master Digital Amplifier and the Digital clear audio technology makes the audio all the more attractive. This particular combination has several resulting benefits like the production of audio that is highly rich and ultra – low distortion, which is very negligibly low. Noise cancellation technology is also employed, which thereby reduces a large portion, approximately 98%, of the noise that is produced outside. The headphones are also enabled with the noise cancellation technology, which totally cancels out the outside noise for making your better enjoyment. The chord, which is of a diameter of 13.5 mm, ensures a greater flexibility. The AV adapter that is supplied along with A845 walkman offers better convenience with regards to the connection to planes AV system, which makes your moves more and more melodious.

The display of the Sony A845 walkman is indeed of a highly commendable nature. It has a 2.8 inch wide OLED display, which helps the walkman to deliver output with awesome colours and high contrast ratios. Browsing is made easier with its screen scroll view. In this screen view, the users are shown a series of thumbnails which are scrolled for easier search. The faster response time of the walkman is particularly noteworthy. The wide-viewing angle makes it suitable for internet applications like online video streaming, sharing and downloading. The battery powers up to 29 hours continuously and enables a nonstop video playback for about 9 hours. The storage capacity of this cool walkman is 16 GB. One among the most attractive features of the walkman is that it supports a wide range of multimedia file formats. This exciting launch of Sony is anticipated to be in the markets from February 2010.
