Most business broadband needs can be determined easily.  For VOIP, there is no need for more than 90 Kilobytes per second per user, however this value must be present at all times.  The consistency of the call is based on this data stream, and dropped calls and stuttered speech may occur if the business broadband service is not stable.  Depending on your firm’s policies regarding internet usage, additional bandwidth may be necessary to support this need and make absolutely certain that this does not influence your VOIP calls.  For those hosting information, it’s important to consider upload speeds as well as download speed.  The average user is an information taker, while most businesses are information providers.  It’s for these reasons among others that the level of service, as well as the reliability of the providing firm be considered before selecting a business broadband provider.
   
It’s important to note that “capacity” for business purposes is determined heavily upon upload rates in addition to download rates.  As service providers and givers, businesses need to be certain that their upload capacity is sufficient, whereas information takers, such as consumers and personal broadband buyers act as information takers, and value download rate instead.  It is for these reasons that these ideas, combined with reliability of firms should be considered first before any decisions are made.

Pros

The design of the Curve 8300 is even more attractive than some earlier BlackBerry mobile phones marketed to consumers.  It’s thin enough to fit comfortably in the hand, but spacious enough to support a full QWERTY keyboard.  The 64mm screen features 320×240 resolution and produces sharp, clean images.

Messaging remains strong as ever:  instant email access, SMS, MMS, and BlackBerry Messenger.  There’s support for attachments including Microsoft Office documents, PDFs, and media files.

For multi-media applications, the Curve 8300 performs admirably.  The media player handles a wide range of formats, and sound quality is very good.

Cons

There’s significant glare off the screen, and the surrounding chrome accents certainly don’t help matters.  The microSD slot is positioned inconveniently underneath the battery, and there’s no microSD card bundled with the phone.

Even the most consumer-centred new mobile phones are moving toward 3G data connection, but this is missing from the Curve 8830.  Downloads and web browsing are hampered by the slow connection.

The 2 megapixel camera is miserable, lacking more than the most basic features.  Images are grainy, poorly coloured, and dull.

Conclusion

Ease of use goes a long way to make up for the Curve 8830’s lack of features.  Users who compare mobile phones, however, are likely to find other products with more advanced multi-media offerings.

Lurking in the middle of the battery cover, the camera shoots video at 720p with motion that remains smooth and clear (videos at this resolution are often distinctly jerky) and there are two dedicated buttons – one for stills, the other for videos, which makes operation a breeze. The still shots are crisp and detailed, although they’re just a little muted in the colour department. You’ll probably be aware that HD footage guzzles a lot of storage space, but the Sony Ericsson Vivaz comes with a capacious 8 GB micro-SD card as standard. There’s an irritating design glitch here, though: to get at the card, you have to remove the battery. Hurrumph to that.

At 3.2 inches, the display is generous without being massive (the Sony Ericsson X10’s screen is a stunning 4 inches). For the size of screen, the 640×320 pixel resolution is more than adequate, making browsing the web a delight – videos, graphics and even text look fabulous.

The main downsides lie in the use of the cumbersome and sluggish Symbian S60 OS and the choice of a resistive rather than a capacitative touch screen. But there are plenty of preloaded apps (including a YouTube player), the GPS is excellent, and the phone’s HSDPA and Wi-Fi will permit fast data downloads wherever you are. And you’ll get at least 2 days out of a single charge of the battery. If you like contract mobile phones, you can pick this one up for a not too unreasonable £25-a-month over two years. SIM-free, it’ll set you back about £350.

Free laptops with mobile broadband contracts work in a similar way to free mobile phones given away with a new mobile contract. When you commit to a contract the mobile service provider knows exactly how much the minimum income is from your contract. It can then work out how much profit it will make from the contract and then out of that profit buy and deliver to you a mobile phone or indeed a laptop computer.

Remember however that you are effectively paying for the laptop by signing up for a mobile broadband contract with a fixed period at a monthly rate that is higher than if you were to sign up for a contract without a free laptop. In essence you are paying off the cost of the laptop over the life of your contract.

If you decide to take out a contract with a free laptop you need to check whether the premium you’re paying for the contract, multiplied by 12, 18 or 24, is more than you would have paid for if you purchased the laptop outright. Of course if you can’t afford to pay for a laptop out of your own pocket, getting a contract which includes a laptop is a reasonable option.

As with any service contract make sure to visit a mobile broadband comparison site to find the best deal. Check whether the included usage – e.g. 512MB, 1GB – is sufficient for your needs and whether the service provider offers mobile broadband coverage in your area.

It has a very small external screen which only displays the time and a 65k internal screen measuring 176 pixels by 220 pixels which is just about adequate for watching video clips and viewing photographs. The superb onboard camera has a 4x zoom and the video capture is excellent quality.

The Motorola E550 comes with a selection of J2ME™ games built ii, including ‘Wakeborder’, and ‘Photofun Editor’, and others can be downloaded if required. Bluetooth ability makes it possible for a call to be taken on a headset when the user is not close to the phone.

There are a mixture of polyphonic and mp3 ringtones for the Motorola E550 and these can be downloaded from the internet if the user fancies a change of ringtone. The Motomixer remixable ringer lets the user play with the ring tones, mix match, merge, etc and can be a lot of fun to play with.

Text messaging (also called SMS) and multimedia messaging (MMS) which sends sounds, pictures to other compatible mobile phone handsets is very easy and somewhat intuitive to use.

Samsung mobile phones have certainly made progress on their original AMOLED screens – although they were amazingly bright and crisp, their glossy finish made viewing difficult in daylight. The Super AMOLED is considerably less reflective, and all the better for it. And the Wave’s Super AMOLED also happens to be super-responsive, too, which makes navigation a pure delight. Like the Galaxy, this highly sensitive capacitative screen supports multi-touch – to zoom in on a text or image, you just pinch your fingers together and, hey presto, you’re closer. You’ll also find that the phone includes HSDPA for super-fast web browsing over 3G, as well as GPS and the very latest 802.11n standard of Wi-Fi. You can also expand the integral 2 GB memory to a jaw-dropping 32 GB with a micro-SD card – and that camera’s a dream: not only will it automatically compensate for dark areas with a quick touch of the screen, it also shoots superb 720p HD video.

The Samsung Wave uses the new ‘Bada’ OS rather than Google’s Android, and Samsung believes this will deliver more smartphone features to less expensive phones. We’ll have to wait and see, but in the meantime, the Wave is a truly smart-looking smartphone at a reasonable price.

What’s most noticeable about the LG GW520 is its full QWERTY keyboard.  This is an excellent keyboard, having keys which are nicely spread apart and large enough to eliminate mistyping errors. The keyboard also carries a set of arrow keys, perfect for scrolling up and down a webpage or conversation. This keyboard combines with LG’s LiveSquare software, to create an ideal instant messaging device, combining a wide variety of protocols and programs into one simple system. 

While the software may be adequate, and the GW520’s keyboard may be suitable, this phone suffers from several key hardware issues that simply make the phone inferior to other models. First and foremost, the provided touch screen is simply not sensitive enough. The arrow keys quickly turn into a necessity rather than a convenience factor, simply because the touch screen cannot be effectively scrolled through. In addition, the 2.8 inch screen, while a decent size, is simply not large enough for some social networking apps.  The face book application quickly begins to look cramped, and difficult to read.

The GW520 is an honest attempt, however due to the glaring faults of the product, it cannot be recommended.  Hopefully LG takes this device as a lesson, and improves future QWERTY keyboard, touch screen smart phones. Please check mobile phone reviews for other LG products, or compare mobile phones from other manufacturers.

Every activity you do on the internet involves the transfer of data, measured in megabytes (MB) or gigabytes (1 GB = 1024 MB). This transfer of data costs your service provider a fee which they need to pay to wholesale providers. To limit their costs your broadband provider puts a limit on how much data you can transfer or ‘use’, especially if you choose a cheap monthly package which does not deliver much in the way of profit to your service provider.

A usage limit of say 3GB may or may not be enough depending on what you do with your connection. Checking email and accessing online banking is unlikely to get you even close to 3GB’s of usage. However downloading an audio track uses around 4MB, so 750 audio tracks downloaded would approach 4Gb. Watching a video on BBC iPlayer uses about 250MB every hour – 3GB will give you up to 10 hours, but no more.

In other words if you watch a lot of BBC iPlayer videos and download plenty of music tracks you should probably be looking at a usage cap of about 20GB or unlimited usage. One word of caution here: unlimited usage almost always come with a ‘fair use policy’ which either dictates a usage limit beyond which your use would be considered as ‘unfair’ or a broad statement about how your connection might be suspended if your usage is deemed as ‘unfair’.

To get a grip on how much you usage you need you may want to visit a broadband comparison site which often has an interactive calculator that can work out how much bandwidth you need. You should then compare broadband deals to see which broadband UK providers offer the usage package you need.

Pros

Much like the Wii gaming system, the Yari features gesture-controlled gaming.  This is a unique innovation uncommon to most new mobile phones.  Some games require the user to move the entire handset, while others let users prop the phone and use their hands to move the characters.  The gesture controls are not always practical – try using this mode in a crowded pub while waiting for a friend, for instance – but they’re definitely good fun.

There’s a built-in GPS, a 5 megapixel camera with good picture quality, simple photo sharing capabilities, and a chic, stylish outer casing.

Cons

The Yari has a lot of buttons.  It’s very easy to fumble with the keys or accidentally press the wrong button.  There is a learning curve, as with most new mobile phones, but initially it feels very user unfriendly.

Music playback is underwhelming, though the music player itself is quick and easy to launch.  As with many Sony Ericsson mobile phones, there isn’t a 3.5 mm headphone jack.

Intensive apps like games load painfully slowly, and customisation is limited.  Web navigation is badly pixellated, making pages appear outdated despite the Yari’s 3G speed.  There is no Wi-Fi connectivity – a glaring omission.

Conclusion

The Yari is a pleasant mobile phone with great gaming capabilities.  The overly complex button layout and proprietary headphone jack do little to stand in the way of basic phone and messaging functions.

There are many toxic chemicals and elements used in the manufacture of a mobile phone including Arsenic, Beryllium, Cadmium, Mercury and Lead. With the sheer volume of mobile phones that are being discarded on an annual basis the amounts of these chemicals leeching into the environment from landfill sites is thought to be considerable. These chemicals can be reclaimed safely from mobile phones and re-used if they are handled properly or the phone itself can be re-used if it is still in working order.

In recent years various companies have appeared offering mobile phone recycling or re-use services. These companies offer a small cash sum for your old mobile phone, which varies depending on the model and whether the phone can be re-used or re-cycled. This prevents the phone from ending up in a landfill site and offers the consumer an incentive to recycle their phone. It is certainly something worth considering the next time you are offered an upgrade.
