Traditionally, there have been two major cellular technologies in our world of communication, these being CDMA and GSM. Others do exist, but these are the primary players available. Up until this time, a variety of restrictions have been imposed or exist, as a result of diverging technologies and other issues. A truly global phone may be just around the corner, however.
It is difficult to know why the United States is behind the rest of the world when it comes to cutting edge cell phone service. In the USA, there are two primary cellular technologies and a somewhat awkward and fragmented relationship exists between them. While CDMA and GSM networks coexist here, the majority of the rest of the world values the flexibility given them by the GSM network.
Cellular service flexibility is not as obvious in North America, unlike the vast majority of consumers around the world. It is difficult to know why the US is not leading the cellular industry in innovation as it seems to be the leader in most fields within technology and science.
When the North American consumer is getting ready to take an annual vacation to somewhere like the Mediterranean, for example, a lot of confusion exists. For a start, will he or she get cell phone service at all and if so, what about those different cellular technologies?
A hybrid solution to the problem of phone interchangeability may be around the corner in the world of cellular technologies. Internet protocol and GSM network delivery may be soon adopted by new providers and services. A lot of the restrictions will disappear and you will not need to “roam” to access a list of services including e-mails, data and unlimited calling. In addition, international calls will no longer be prohibitively expensive.
By and large the consumer is usually oblivious to the global confusion within the cellular world, but anticipated innovations will nevertheless provide clear benefits including the elimination of lengthy contractual commitments and a reduction in monthly fees.
In Europe, consumers travel freely between member countries and only have to change out their SIM card within their primary GSM phone for complete flexibility of service.
North America differs to the rest of the world by relying on distinct frequencies to transmit cell phone services. Thus a consumer must be sure that he or she has the latest type of phone, working on a tri band or quad band basis to enable and pick up the foreign frequencies.
