Smartphones – 3G, 4G, Data Plans, Wi-Fi And More…

Recently in our classes (back east) we’ve been discussing “Smartphones” and these are a few of the questions that were raised which might be of interest to you... 

What does the G mean in Cell phones – 3G, 4G etc?  That’s easy, the “G” stands for the “Generation” for cell phone technology…with new generations coming out about every ten (10) years – the technologies were introduced as follows but usually were marketed by cellphone companies a year or two after introduction…

·         1G was introduced in 1981 (analog)

·         2G was first transmitted in 1992 (digital)

·         3G which offers multi-media support came out in 200, but came to the US in 2003

·         4G introduced in 2010 but widely used by cell phone carriers now in 2012

If you live in an area that doesn't have 4G coverage, there's no advantage to a 4G phone. In fact, you'll have serious battery life problems if you buy an LTE phone and don't disable 4G LTE, as the radio's search for a non-existent signal will drain your battery quickly…  Before you buy any cellphone “smartphone or not” be sure to check the coverage offered by the different carriers…one of the most important considerations before you decide who to go with, so you know you’ll be able to send/receive calls where you normally live, work or visit..

What does all this “data” stuff mean on a cell phone?  Most activities on “smartphones” will consume data – the exceptions are making a phone call and sending a text messages.  Remember, voice and texts require a very small amount of bandwidth, as opposed to data, which requires carriers to continuously build up their networks to support exploding demand from smartphones and tablets..

That is why activities, such as browsing the web, reading and sending e-mails, browsing Facebook, Twitter, Pinterest, LinkedIn, or sharing photos, downloading applications, downloading music, listening to online radio and watching videos on YouTube, viewing maps, instant messaging applications such as Skype, BlackBerry Messenger, WhatsApp, Google Talk and Facebook Messenger – all of these activities use up data and quickly…

Many phones consume data in the background even when you’re not using it – maybe you have the weather widget on your homescreen, so periodically it’s downloading the latest forecast from the internet or your email app, might be checking for new messages..  it all adds up.

What if I use the Wi-Fi with my phone?  Good news-Any data transferred over a wi-fi network WILL NOT count towards your download limit.  Data transferred over a wi-fi network does not pass through your mobile operator and so it won’t be counted towards your monthly download limit. So it’s best to use a wi-fi network for all of your bandwidth-intensive activities such as listening to online radio, making calls over Skype and watching online video. But be sure you know if you have a separate download limit with your home broadband connection.  You can set your smartphone to find available Wi-Fi networks for you…

What about the data plans that say they are unlimited?  According to some experts, “Paying for an “unlimited data plan” (even if your carrier offers this, which many don’t anymore) doesn’t mean you get unlimited access to your carrier’s bandwidth. AT&T, T-Mobile and Verizon Wireless “slow down or what is called throttling” data users after they reach a predetermined limit. Sprint is the lone hold-out, but rumors point to the possibility that the carrier will begin to throttle data on its Virgin sub-carrier plans. The justification for this process involves regulate network traffic and minimize bandwidth congestion. And with the rise in 4G data usage, carriers claim their networks are jammed, so what this means to all of us – the consumers – is that we may not get to take advantage of all the speed promised by our new 4G smartphone” quoted from PC Net Magazine – Feb 2012

No doubt, all of this will continue to change – so keep your questions coming and we will help you find the answers – remember there are no foolish questions – all of the technology today is changing so rapidly that it’s a challenge for all of us to keep up with what’s happening, never mind understanding all the ins and outs entirely…  It’s simply a constant learning experience..

Router or Modem – What’s the difference?

Routers and modems are “hardware” – They are individual devices with very distinct and separate functions.

A ROUTER is not really essential for internet communication. It is still possible to connect to the internet without routers just like in the old days with internal PCI modems. But you should remember that the main job of the router is to protect you from possible threats and malware, and this shouldn’t be taken very lightly

A MODEM, is the device (or piece of hardware) that allows us to connect our computers – either wired or wirelessly – to the internet. Typically, the modem you use will be provided by your internet provider – you can purchase your own, but be sure that the model you choose will work with the connection from your internet provider (telecommunication company, cable company or satellite provider) before making the purchase. Without a modem, you cannot connect to the internet.

More and more often today, you can purchase combined router/modems so that you don’t have to have 2 separate devices in your work area, such as wi-fi modems that are equipped with routing capabilities which can be wireless or wired or both. There’s no question that in the future, there will be no practical need for cables anymore and all wi-fi modems will also have wi-fi router functions.

INCREASE YOUR LAPTOP BATTERY'S LIFE

Without fail, the battery on our laptops – notebooks or netbooks, always stop working and run our of juice at the most inconvenient time – in the middle of that rush report or when you are on a flight and watching a DVD movie

Laptop screens take up significant amount of power and we usually don’t require maximum brightness, so check your system and decrease the screen brightness it to a comfortable point.

Stop your wireless signal when you aren’t using it - After turning off your Laptop, right click on your WiFi control signal and be sure it is off to save a considerable quantity of battery power

Check your power plans - Windows XP has several predetermined power plans to control settings like how rapidly your laptop turns off and when your screen saver boots in. You can change your laptop power scheme by choosing Control Panel, then choose Power Options. For maximum battery life from the “Maximum Battery” option from the "Power scheme" and decline the list. Other good choices might be "Low Power Mode" and Portable /Laptop – they may not conserve as much power as Max Battery, but they still help. After choosing the power scheme, click Ok to finish the process.

Protect your mobile devices - cell phones, blackberry's etc.

We received these tips from State Farm Insurance and thought you would find them helpful…

Smartphones (iPhones, Droids, etc); Blackberry’s and other mobile devices are just “always-on computers” that can make phone calls." So how can you protect your phone and your identity from this new breed of mobile-minded criminal? Here are some tips:

Protect your phone
Use common sense in protecting your smartphone from hackers and identity thieves. Don't let strangers borrow your phone, protect access to e-mail and sensitive data with a PIN or password, don't use unofficial apps for online banking, and don't click on links from text messages. Basically, if you wouldn't do it on your home computer, don't do it on your smartphone. Be wary of free apps that aren't from established, trusted, familiar sources. Steer clear of pirated app repositories; stick to official versions for safe mobile surfing. And when you use public WiFi for Web access, don't visit sites that require you to share sensitive personal information such as account numbers or your social security number. Hackers may lurk on WiFi networks.

Watch bills vigilantly
Check your bill carefully each month. If you see downloads you didn't authorize or calls you didn't make, contact your wireless provider immediately. If you receive a confirmation e-mail when you download an app, take time to actually read through it so that you know exactly what you are putting on your phone—and where it's coming from.

Question quirks
If your home computer started doing bizarre things like shutting down without warning, sending unauthorized email messages or pulling up websites that don't match the address typed in, you might suspect a virus. But users don't necessarily make the same connection when bizarre quirks develop on smartphones. Mobile devices will usually issue similar weird warnings when they're infected with malware.

WHAT IS WI-FI??

WI-FI is a wireless network which uses radio waves, just like our cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication.

WI-FI networks can either be "OPEN OR UNSECURED", so that anyone can use them (most public libraries, book stores, BurgerKing, McDonalds and other such sites offer free services) OR "CLOSED OR SECURE", in which case a password is needed. An area blanketed in wireless access is often called a wireless hotspot. There are efforts underway to turn entire cities, such as San Francisco, Portland, and Philadelphia, into big wireless hotspots. Many of these plans will offer free, ad-supported service or ad-free service for a small fee. San Francisco recently chose Google to supply it with a wireless network...

To go wireless inside your home you need to have a high-speed connection, Cable or DSL, and of course as we said, you can use wireless internet access at various locations: McDonalds; Burger King; most public libraries throughout the US, most hotels, truck stops and almost all airports offer WiFi..

A Wi-Fi-FreeSpot is a location that offers Free Wi-Fi high speed wireless internet access to their customers and guests and/or the general public. For locations check out:
