You can use your office PC even when you are not in the office. Now! you can travel, or work from home. Wireless communication allows you to connect with your office PC to check E-mail, add sales or other information to a database, or down load a file you forgot to take with you.

All this is possible by dialing into your office network and becoming a workstation on the network. All files and applications in the office are available out of the office. Information is sent through modems via telephone lines.

Wireless products use either infrared (IR) or radio frequency (RF) transmissions to communicate with one another or with a database. Most wireless devices use a radio frequency spectrum scheme called Frequency Hopping Spread Spectrum (FHSS). It transmits a short burst of one frequency and then hops to another frequency for each subsequent burst. FHHS technology offers your business greater network usage, more power, and better security.
