To be successful, a business traveler must be able to maintain contact with the office, no matter what the time or place. Negotiations often involve decisions based on the latest figures; therefore, modern employers tend to look for those who are able to master state-of-the-art equipment. New telecommunications products and services now on the market make staying in touch easier than ever before.
The most widespread device is the cellular telephone, the price of which has dropped from several thousand dollars to a few hundred, including installation. Users of any budgets can afford one with all necessary functions to meet their need to communicate, to entertain or to study and work. There are over 2 million mobile cellular phones in use today, including both car phones and cordless transportable units. Car phones have proven indispensable for road emergencies as well as routine business transactions. Phone service is also available on airplanes and on the rails.
Recently introduced pocket-size organizers help business travelers with heavy schedules keep track of clients. These are tiny computers that can store all kinds of information that can satisfy any users in spite of any jobs they have. They can serve as phone and address directories, calendars, electronic memo pads, and calculators, among other uses. As a result, this device has become an indispensable assistant for many people.
Another invaluable telecommunications tool is smaller, lighter fax machines that plug into any standard electrical outlet and phone line. The devices allow instantaneous transmission of hard copy to any location having a compatible fax machine. It is expected that faxing will soon become the primary means of sending and receiving short documents requiring prompt attention. Fax machines have come in a wide range of models and greater offer of applications.
