Due to a lack of financial resources, we unfortunately have to suspend the import of any new radio frequency and mobile phone-related articles as of now (November 27, 2017). We apologize for this inconvenience and will keep you informed.

Because we received a large number of inquiries, we set up a bank account to accept donations. With their aid, we hope to resume, at least partly, the import of newly published articles to the RF archive of the EMF-Portal. Any contribution is greatly appreciated. Thank you for your kind support!

cordless telephone

  • cordless phone
Communications engineering. A phone that does not have a cord between the handset and the base unit. Cordless phones allow users to roam a short distance (about 50 to 300 m) from the phone's base. Early cordless phones used analogue technology; however, many cordless phones manufactured today employ digital transmission technology (e.g., DECT).
