When purchasing a cellular phone there is always the question of analog or digital. In analog cellular service the voice is transmitted over a specific radio frequency, usually 800 MHz. digital cellular service on the other hand breaks the voice down into a binary format where the voice is represented by a series of 1’s and O’s. These simple definitions will help to familiarize yourself with the two systems, but to truly determine which phone is right for you there are four issues that should be addressed, cost, sound quality, coverage, and features.
Cost is an issue that is important to everyone so it must be considered when purchasing a cellular phone. Analog is the original cellular phone type, since the technology has been around for over 20 years these phones are considerably less expensive than digital phones. The cost of digital phones is higher because the technology is relatively new, and the phones tend to come with more features. Although, the minute rates tend to be higher for analog phones than that of digital. When comparing cost you must look at both the cost of the cellular phone and the cost of the cellular package.
sound quality is a crucial point to consider when purchasing a phone especially if it is going to be used for business purposes. Analog phones do not offer the best sound quality available in the cellular phone market today. One of the biggest advantages of digital phones is the sound quality. The binary code utilized by digital enables it to know exactly what it should be when it reaches the end of the transmission. That way, it can correct any errors that may have occurred in the data transfer. This means clarity, digital phone users receive the benefit of distortion free conversations.

The issue of coverage also needs to be discussed when purchasing a cellular phone. Due to the fact that analog phones have been around for over 20 years they basically cover most rural areas. On the other hand, most digital networks are concentrated in urban areas. Digital equipped antennae are not yet covering the country the way that analog is, but they will be soon. Although overall coverage is better with analog, digital cellular allows more people to use their phones within a single coverage area. More data can be sent and received simultaneously by each phone user.
When looking at features the user needs to determine what they will be using the phone for. Analog phones have very minimal features; they usually just have basic functions. If you need a more complex phone you should go for digital. Digital phones allow you to get text messages, wireless web, voicemail, caller ID information, and also provide more security than analog phones. Digital is also responsible for the new all in one devices such as the palm pilot, which can also be used as a phone and pager. The nature of digital technology allows it to fit many 1’s and O’s together into the same space an analog signal uses.
Ultimately the phone you choose will depend on where you will be using it and what you will be using it for. Whether you go analog or digital depends on a number of things, it also might just be personal preference. Some people do not use their phone enough to care which type of signal it uses. The people that are going to be faced with the analog versus digital dilemma are the heavy cellular phone users. Although some people feel the question is a no brainer the analog system for the time being still offers some useful benefits.
