How Young Is Too Young For a Cell Phone?
Are We Taking Cell Phone Usage Too Far?
The other day at the playground, I watched as what looked like a 5-year-old girl answered a cell phone call from her grandmother. No, it wasn't her mom or dad's cell phone she was using -- it was her own. Which raised the question -- are kindergartners too young to have their own cell phones? The answer may surprise you.
Practicality Counts
Listen, anyone who knows me knows that I'm not one for the overindulgence of children. In fact, I think the excess of spoiling our children is the reason why we have so many disrespectful irresponsible young adults running around today. That being said, however, I do honestly think that giving a cell phone to children of all ages isn't really a bad idea.
A Changing World
We have to admit the fact that we live in a changing world and the cell phone is a big part of that world. Years ago when I was little, I remember getting lost at an amusement park. What seemed like hours later, I was reunited with my mom. What if my mom and I had both had cell phones that day?
Think about it. You're at the mall with your 7-year-old and suddenly he's not next to you anymore. Instead of the panic attack most parents experience at this point, you simply call your son's cell phone. He answers, you find out exactly where he is and you go get him. No harm, no foul.
Or what about this... Your 12-year-old is at soccer practice and you're going to be about five minutes late picking him up due to an accident that slowed traffic. You call your son on his cell phone and tell him you're running late and to wait for you. Now your son doesn't worry when you don't show up right on time and you don't worry about your son having to worry.
Let's face it -- we all have enough stress in our lives when we're parents. If a cell phone can reduce that stress, I'm all for it.
Not All Cell Phones Are Created Equal
It is important to realize that not all cell phones are created equal. I do not advocate getting a flip phone with a camera and a mp3 player for a 1st grader. In their case, a Firefly or Migo will do. There are a number of age-appropriate cell phone options on the market. If you have kids, I suggest looking into them and getting them a cell phone that suits their needs and their age.

Cell Phone Business Market - No Longer Luxury
How big is the cell phone wireless market?
The boom in mobile phone usage expands around the globe covering all income spectrums. A cell phone is no longer an expensive business luxury or status symbol but a vital necessity for many.
Companies from all industries and markets are vying for a share of a large and ever growing mobile pie including RIM, Apple, Microsoft and Google. With a flood of large competitors, is there room to start a mobile phone business?
Big business means big investments in technology and infrastructure to further build out the business. For the small player, the opportunity to start a cell phone business exists on the fringes or niche markets.
Mobile Phone Business Driven by Smartphones
Fueling the growth of the cell phone market is the evolution from standard cell phones to smartphones capable of more than a simple phone call.
Smartphones allow users to browser the Web, get GPS directions, listen to music, share photos and other forms of social networking, use email and run applications such as games and more.
Starting a mobile phone or cell phone business can be a profitable business opportunity in a growing market. At the Consumer Electronics Show, Dr. Eli Harary stated “the mobile phone market is the mother of all growth markets.”
Opening a retail cell phone store is one route to get into business. However, retail can be an expensive, competitive, low margin game. Alternative business opportunities exist for the mobile business.
5 Hot Mobile Phone Business Opportunities
The hottest opportunities to start a mobile phone business include:
Mobile Marketing: With billions of mobile phones around the world with greater penetration than the PC, the potential for advertising and market is huge. Although the current spend on mobile ads is a drop in the bucket of the $500 billion dollar ad market, the upside looks good.
Mobile Phone Apps: 3rd party applications ranging from business productivity to game downloads offer a viable business opportunity. Simple apps like Ocarina allowing iPhone users a way to turn their phone into a wind instrument is a top 99 cent download.
Apple, RIM and other companies provide a third party application developers fund to fuel investment in the app development market.
Mobile Web Design: It would seem most web sites are mobile ready but mobile readiness is far from business web development radar. The challenge of fitting web pages on tiny screens for multiple devices with easy navigation is a market need for a long time coming.
Location Based Services: Cameras in the phone were a killer application but now having GPS (Global Positioning Satellite) on the mobile phones provides a host of new business opportunities.
The combination of social networking and GPS provides exciting opportunities in allowing users to update friends on one’s location and tag favorite place.
Accessorize: From fashion conscious teens to savvy soccer moms, the need to customize, personalize and bling out your cell phone is a strong market. Smartphones Experts, a network of mobile phone e-commerce stores, grew from under $500,000 in revenue to over $16 million in 3 short years.
Starting a mobile phone business is a continued market opportunity and with more consumers looking to upgrade from a cell phone to a smartphone, the future looks bright for this business.

Cell-phone Channels
A single cell in an analog cell-phone system uses one-seventh of the available duplex voice channels. That is, each cell (of the seven on a hexagonal grid) is using one-seventh of the available channels so it has a unique set of frequencies and there are no collisions:
* A cell-phone carrier typically gets 832 radio frequencies to use in a city.
* Each cell phone uses two frequencies per call -- a duplex channel -- so there are typically 395 voice channels per carrier. (The other 42 frequencies are used for control channels -- more on this later.)
Therefore, each cell has about 56 voice channels available. In other words, in any cell, 56 people can be talking on their cell phone at one time. Analog cellular systems are considered first-generation mobile technology, or 1G. With digital transmission methods (2G), the number of available channels increases. For example, a TDMA-based digital system (more on TDMA later) can carry three times as many calls as an analog system, so each cell has about 168 channels available.
Cell phones have low-power transmitters in them. Many cell phones have two signal strengths: 0.6 watts and 3 watts (for comparison, most CB radios transmit at 4 watts). The base station is also transmitting at low power. Low-power transmitters have two advantages:
* The transmissions of a base station and the phones within its cell do not make it very far outside that cell. Therefore, in the figure above, both of the purple cells can reuse the same 56 frequencies. The same frequencies can be reused extensively across the city.
* The power consumption of the cell phone, which is normally battery-operated, is relatively low. Low power means small batteries, and this is what has made handheld cellular phones possible.
The cellular approach requires a large number of base stations in a city of any size. A typical large city can have hundreds of towers. But because so many people are using cell phones, costs remain low per user. Each carrier in each city also runs one central office called the Mobile Telephone Switching Office (MTSO). This office handles all of the phone connections to the normal land-based phone system, and controls all of the base stations in the region.
