For the foreseeable future, society's intertwined relationship with mobile phone technology looks to continue growing unabated. As the way we use such devices expands, so to does the demand for higher speed communications, greater bandwidths, smaller more capable devices, longer battery lives, which in turn has increased the demand for further innovation and new ways of taking advantage of that ability. Mobile phones have changed how we interact as a species; how we story-tell, share information, and communicate in a modern age.

Cell Phones we shaped by society by society wanting and needing a technology that could enable them to be more easily connected to their home, work, families and friends. The evolution of the cell phones is changing constantly. Cell phones over time have come in many shapes and sizes. It started with the Brick phone, then the clamshell, candy bar, satellite phone to PDAs. In the 2000's more affordable and practicable cell phones were released like the Nokia, Razr and Blackberry. These devices were more for the everyday consumer, these were smaller, affordable and continued to change based on societies preferences. We would eventually see apps, cameras and internet connectivity. Society didn't was huge bulky brick phones or satellite phones anymore.

# data[].attributes.attachment_link.readable_text
In April 1973, Motorola engineer Marty Cooper made the first call from a "real handheld portable cell phone," a point he made very clear during that historic conversation with Joel Engel, the head of rival research firm Bell Labs. Fast forward to June 29, 2007, and the iPhone was born. Now in 2014, innovation is showing no sign of slowing down.

Since that fateful phone call four decades ago, mobile phones have evolved dramatically. Those magical portable technology boxes have become an essential part of interpersonal communication, and their significance will only increase with time. From the rise of SMS to anywhere, anytime Internet connectivity to mobile photography, cell phones have been the catalyst for cultural and technological changes over the past 41 years. Let's relive the defining moments and trends of the mobile era.

Radio Common Carrier (RCC)

This soldier was using a radio common carrier, which was introduced in the '60s as a precellular system. Like a radio, it could transmit voice communication through a push-to-talk system, but it used a public telephone network and had its own telephone number.

Brick Phone

Gordon Gekko may have been the star of Wall Street, but his Motorola DynaTAC played a major supporting role. The classic brick phone had an LED screen and boasted 30 minutes of talk time with eight hours of standby. The DynaTAC was priced at almost $4,000 in the early '80s - no wonder it made its first appearance in the hands of bankers on Wall Street!

It was this phone with which Motorola employee Marty Cooper made the first mobile phone call.

Brick Phone

Here's Marty showing off the cell phone he used to make that historic call.

The Clamshell

The first foray into truly portable devices was the clamshell form factor. Motorola was a pioneer in this front, with the MicroTAC, which looked much like the one Whoopi Goldberg was using in 1989.

The MicroTAC had a red LED display and a standard 12-button keypad, plus a menu of options including a calculator, hands-free operation, keypad tones, and much, much more. By the time that MicroTAC was announced, the phone still cost consumers upward of $2,500.

The Candybar

Nokia was at the forefront of this type of device. The candybar phone was named as such, because it was approximately the size and shape of, well, a bar of candy.

The Elites

The mid-'90s was a period of evolution for the mobile industry. The clamshell phone shed some heft and paved the way for the modern flip phone.

Satellite Phone

This Motorola hybrid satellite/GSM phone was one of the first of its kind. A satphone connects to orbiting satellites, rather than Earth-bound cellular towers, which means it can make a call from essentially anywhere in the world.

The PDA

The personal digital assistants of the '90s ushered in a wave of pocket computing and touchscreen devices. The industry game changer was popularized by Palm, which launched the Palm Pilot in 1997 for a retail price of about $200-$300. The virtual keyboard, handwriting recognition, and Internet connectivity were cutting-edge technologies during that time.

Nokia 6000 Series

Snake! Interchangeable face plates! You either knew someone who had a Nokia 6000 Series phone or owned one yourself. The popular cell phone of the early '00s made mobile communication affordable and widely available for the masses.

Creative Keyboards

Mobile-phone manufacturers looking to capitalize on the rise of SMS created a variety of wacky-looking phones that incorporated full-size QWERTY keyboards.

Razr

Ohhhh, the Razr. The slim, sleek, and superpocketable form factor made the Motorola flip phone, which launched in 2004, a surefire hit among the fashion-forward crowd.

BlackBerry

The BlackBerry email client and BlackBerry-to-BlackBerry instant messaging took the mobile world by storm when it made its debut in the early '00s. Thumbs were never the same again.

T-Mobile Sidekick

Originally named the "Hiptop," the T-Mobile Sidekick was an SMS-friendly phone for the next generation of texters. Like, for texting your BFF Jill.

The iPhone

The world wasn't quite ready for the iPhone when it was unveiled in 2007. Apple founder Steve Jobs launched the all-in-one digital music player, camera (2MP!), and Internet-enabled PDA device, and the rest is history.

Apps Take Over

App-enabled smartphones took over the market after the release of the iPhone. Google's open-sourced Android platform made it possible for manufacturers like Samsung, LG, HTC, and others to create devices based on the mobile operating system.

The Fire Phone

In June 2014, Amazon got in on the cell phone game with the Fire phone. It comes with pretty innovative features, including a better camera and free photo storage in the cloud, 3D features, and Firefly technology, which can recognized 100 million items in the real world.

The Future

The Future Touchscreen phones are getting lighter, wider, and more powerful-but what else can we expect for the future of mobile communication?

Devices will be more resistant to their environments and (hopefully) get much better battery life as technology advances. Sony launched the waterproof Xperia Z at 2013's CES, and Samsung followed suit in 2014 with the waterproof Galaxy S5.

Cells phones shaped society by keeping us all more closely interconnected. With the technology of a cell phone we are able to call and text and stay connected more easily and more frequently. 94% of all Americans have cell phones. Cell phones have become a staple in our everyday lives.

# data[].attributes.attachment_link.readable_text
Many companies are looking towards mobile resources to enhance their learning and development programs. However, some learning and development apps or programs are hard to access for those that don't have a smartphone. Text messaging (SMS) is a great way to help employees or customer retain information on any phone. We've put together a list of 8 statistics about how we use cell phones and especially text messaging.

1. (Almost) everybody's got one : 94% of all Americans have cell phones, which means that 9 out of 10 people have a cell phone on them, ready to connect and communicate, whether on a smartphone or not.

2. They're our best friends : We have them with us for roughly 16 hours a day. If there's a way to contact someone anytime, anywhere, cell phones are the way to go.

3. You probably look at it more than you think : On average, we check them 150 times per day. You only thought you didn't check social media that often!

4. They watch us while we dream : 68% of us have them next to us while we sleep. Does this mean we check notifications in our sleep, too?

5. A whole lotta mail : We send over 6 million text messages every day. That is the equivalent of over double the population of Los Angeles, California!

6. To be exact: That's 763 text messages per person per month. Just from this cell phone statistic alone, imagine all the different kinds of conversations and opportunities there are just in text-messaging conversations.

7. People want to hear what we say: 99% of text messages that we send are read. We can't stand those "unread message" symbols on our phones!

8. Our texts are read right away : 90% of texts are read within 3 minutes of receiving them. This is a significantly better statistic than unread or trashed emails in our inboxes.

These cell phone statistics show that we love our cell phones, and the most efficient way to reach anybody on mobile device is through text messaging. Feel free to share this information with your network!

WiMax and LTE network deployment begins across the US. WiMax, a competing standard would be short lived and is quickly surpassed by the adoption of Long-Term Evolution, which would eventually replace it entirely. 4G technology included the transition to Internet Protocol (IP) packet switched communication , which paired with more efficient spectrum usage, multiple streams, and higher bandwidths, enabled data connections up to a gigabit in speed. (It should also be noted that another big advancement was that all of it was using software defined radio, which every modern cell phone now contains in some form. This is one reason modern mobile phones are able to work with an array of underlying frequencies and mobile standards).
