How well do you function in today's wired world?Today's businesses Today's Business is a show on CNBC that aired in the early morning, 5 to 7AM ET timeslot, hosted by Liz Claman and Bob Sellers, and it was replaced by Wake Up Call on Feb 4, 2002. are measured by how well they function in the "wired" world. They need access to state-of-the-art communications services that will get them plugged into the e-conomy. Tenants know that building owners and managers determine the telecom services they can access, and want owners to make informed choices that will give them the broadband services See broadband and broadband service provider. they need. This column is part of a monthly question-and-answer series on telecommunication services designed to help real estate professionals compete for and retain tenants. What are the different wireless technologies and how are they each used? The many different wireless service devices and service packages are based on just three commonly used wireless technologies: * Cellular wireless is used primarily for mobile voice communications. Cellular systems use an analog signal An analog or analogue signal is any time continuous signal where some time varying feature of the signal is a representation of some other time varying quantity. It differs from a digital signal in that small fluctuations in the signal are meaningful. , which requires a separate modem to transmit data. Some cellular phones cannot access the Internet even with a modem. Cellular signals are transmitted within a defined area, or "cell," by arrays of large antennas, which often have fragile connections with their indoor electronics. * PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. , or personal communications systems In telecommunication, a communications system is a collection of individual communications networks, transmission systems, relay stations, tributary stations, and data terminal equipment (DTE) usually capable of interconnection and interoperation to form an integrated whole. , uses encrypted digital signals and can handle both mobile voice and data communications data communications, application of telecommunications technology to the problem of transmitting data, especially to, from, or between computers. In popular usage, it is said that data communications make it possible for one computer to "talk" with another. . Only one PCS format is currently used for data transmission; there are also voice-only formats. PCS systems can be designed to send and receive faxes and e-mail, transfer files, browse the Web, and transmit pager-type messages, eliminating the need for a separate paging device. Like cellular, PCS uses large antenna arrays that operate within a geographic cell. * Fixed wireless provides broadband service between buildings, rather than serving mobile users. Signal quality and reliability are equivalent to fiber-optic cable. A typical fixed wireless installation uses one or two small antennas set up for line of sight transmission to other antennas. The technology is inherently robust and resilient to flooding, winds, earthquakes and fiber cuts. Fixed wireless technology provides route diversity and back-up for critical telecom services. Term of the week: Virtual Private Network -- A network that lets mobile users connect with a corporate Intranet or LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. via PCS. Encryption secures the information, and the network can be structured to let users access e-mail, pull down information and transmit data files. * About the Author: Jack Robinson Jack Robinson may refer to:
