To efficiently reuse wireless spectrum, wireless network are divided into cells. In general a cell is a hexagon in shape. Based on the radius of the cells, there are three types of cellular networks, including (1) macrocells, (2) microcells, and (3) picocells.

Macrocellar wireless network

A macrocell can cover a large area with a radius ranging from 1 to 10 km. a distinction can be further made to for large macrocells and small macrocells. A large macrocell can cover a range with a radius of 5 to 10 km, which is mainly used for rural areas with little traffic. In contrast, a small macrocell generally covers a range with a radius between 1 and 5 km. This types of cells are used if traffic density is high. Macrocellar wireless networks transmit a very high radio power to cover a large cellar area. They have low spectrum efficiency due to its large cell coverage. The typical rms delay for a macrocell is at the range of 10us.

Microcellar wireless network

Microcellar networks are deployed in area with high density of traffic such as suburb. Each microcell generally covers a radius ranging from 200m to 1km. Microcellar networks can be deployed as a chain or in two dimensions. The chain-like deployment is often made along a highway with high traffic densities, while the two-dimension deployment is often made in the city streets. In this deployment, buildings help block signal from neighbouring cells, thereby decreasing co-channel interference. Comparatively, microcellar networks have better spectrum efficiency than that of macrocellar networks. Typical rms delay for microcell is around 2us due to its smaller coverage area.

Picocellar wireless network

Picocellar wireless network is a type of wireless network with the smallest radio coverage. Its radius ranges from 10 to 200m. Such a type of network is often deployed in a room. Thus, it is often called indoor wireless network. Picocellar wireless networks have the best spectrum efficiency among the three types of cellar networks. Also, due to its smallest coverage, it transmits the lowest radio power and has the smallest rms delay ranging from 50 to 300ns.

Summary

Three types of cellar wireless networks are introduced. They cover different cellar areas and are applicable to different wireless communication scenarios. In general, a macrocellar network covers the largest area, but requires the highest transmission power and shows the lowest spectrum efficiency. In contrast, a picocell network transmits the weakest radio signal to cover the smallest area like a conference room. It achieves the best spectrum efficiency.

Getting a prepaid cell phone will allow you a lot of advantages you may not be aware of. As a matter of fact prepaid service may actually be better for anyone who does not spend extremely long amount of time talking.

For business people and other professions that use their cell phones a lot, classic service is still probably better as minutes cost less. However if you are a regular person, who uses cell phone for a quick see you then and there calls prepaid service holds numerous benefits.

1) No contract needed. Maybe you have seen some of the cell phone contracts lately, there has been a trend by service providers to tie up the costumers for longer periods of time then before. More and more contracts are now for at least two years.

With cell phone market getting more competitive each day and new services and deals being offered on weekly basis, ting up yourself with one provider for a long period is just not smart. Besides your financial situation may change and maybe you are not going to be able to afford paying regular monthly bills for your cell phone. And you will get them, whether you use it or not.

2) Overage Fees Do Not Exist. Has it happened to you? You get your bill, open it and see that once again you have spend more then you can afford. No such thing with prepaid cell phone, you talk as many minutes as you have already paid for and if you can not pay for more minutes this month it is OK.

Other people can still reach you and you will buy new credits when you will have the money for it. Besides that, you can talk as much as you want, your rates remain flat.

3) You do not have to worry about fine print. You just buy airtime, you do not buy this amount of minutes per weekdays or that amount per weekends.

You pay just for the minutes you spend talking, when you are going to spend them is entirely up to you. The price stays the same. You also pay flat fee for any video or text message you send, no matter when you send them.

These three examples are just some of the benefits of prepaid cell phones. If you are in the process of shopping for a cell phone, keeping this in mind may help you choose the best service for you.

All of the most popular carriers offer a prepaid service now so you are not limited about who to choose. There are many options available to you, examine some of them and then decide what is best for you.

Almost everyone owns a cell phone these days. People are probably more likely to be homeless than to not have a cell phone. Some people, like me, have more than one cell phone, usually one cell phone is for personal use, and the other one is for business. Cell phones are getting smaller and smaller, but they are also gaining more and more features. There are many cell phones available that can take pictures, send and receive email, open up Microsoft Word documents, and download ringtones to your phone. These ringtones allow you to hear a very unique sound when your cell phone rings. Ringtones are now available in a variety of different types and styles.

Right now I have a ringtone on my personal cell phone that plays musical tones that sound like the Blue Oyster Cult song “Don’t Fear the Reaper”. I have never heard anyone else’s cell phone with this particular ringtone before, so I feel like my cell phone ringtone is one of a kind. This particular ringtone is not actually the words and instruments from this song, but it is comprised of digital tones that match the song very closely. This type of ringtone is one of the earlier versions that were available online. I downloaded this song from a web site that sells a six month subscription to their site for a fixed price, and they allow you to download as many ringtones as you want during the subscription period.

One of the biggest crazes today is to have ringtones with song playing on your cell phone. These types of ringtones sound very good, because they are just as clear as the real song. Many different web sites offer this type of ringtone, which you can buy as a single ringtone, or download as part of a subscription. You can find almost any new release available as a ringtone, but some of these web sites have actually journeyed back into the past and made many older songs available also. Whatever your personality is, you can now find a ringtone to suit it.

Prepaid cell phones are great in case that you have bad credit. Long time ago when prepaid service was first offered this used to be its main advantage for the user. It did not matter if your credit was lousy, you could still get a cell phone and use it just like if you had a perfect credit.

Cell phones are so common these days it is really difficult to find someone who does not have one. Even if you do, it is in most cases by personal choice (your author was one of these, for the longest time I refused to get it, butt becoming a father changed my mind).

All of us need to be able to communicate with a person we care for and that is the main benefit of cell phones. That is why prepaid service is great, you can get it any time you want and nobody will check your credit history for it.

So what are the main differences (concerning credit checks) between prepaid and non-prepaid service?

Prepaid

With prepaid service you simply buy a cell phone, number and minutes you intend to spend talking and there is no need to worry about how it will impact your credit score. Or for that mater, whether you are going to get a cell phone in the first place.

Prepaid service providers just do not care about your credit rating because in order to use the service it has to be paid for in advance. Because it is paid in advance you pose no risk for the company that provides the service. The good thing about it is that you are %100 in control of your budget and it will not show on your credit report no matter what you do.

But remember, prepaid service is not just for people with bad credit, it is far easier to control your spending this way and you do not lose any of the cell phone service benefits. It is especially suitable for people who do not use cell phones a lot. You do not have the pay monthly bills but are still connected if you need it.

Non-prepaid

Regular, non prepaid service will check your credit score before you are approved. Credit bureaus are constantly informed by creditors about your payment history, including the cell phones companies. So remember that an unpaid cell phone bill can result in you being turned down for some other more important credit demand like home or a new car.

With prepaid cell phone service it is never going to happen, because you are %100in control of your budget at any time. It will enable you to easily avoid any trap caused by over spending.
