AOL said the acquisition, together with its AIM and ICQ
personal communications network, will give AOL a strong position in the online social media arena, with a network of around 80m unique users.
NTT has decided to liquidate its nine PHS companies, which form the NTT
Personal Communications Network of PHS services, and transfer their operations to NTT Mobile Communications Network Inc., known as NTT DoCoMo, by this year-end.
Although this design was completed for UHF, a variety of antennas for wireless communication have been developed to cover the other bands, including personal communications service (PCS);
personal communications network (PCN); low industrial, scientific and medical (ISM); and high ISM.
PCN:
Personal Communications Network. The digital network used by Mercury One 2 One and Orange.
MCI is involved with a different type of consortium, one that hopes to win a license to build a national
personal communications network. In its consortium, MCI would be a national manager in charge of network services, technical standards and national marketing.
With the introduction of new mobile phone networks such as the
personal communications network in Europe and personal communications service in North America, ways of reducing the size and numbers of the antennas needed for deployment have become important issues for manufacturers and operators in the industry.
Low loss, dielectric constant [[Epsilon].sub.r] stability over temperature and frequency makes the 25N materials suitable for circuits in many
personal communications network applications such as cellular telephones, downconverters, low noise amplifiers, antennas and others where the higher costs of PTFE materials are prohibitive, yet instability, electrical loss and other shortcomings of lower cost FR-4 materials are unacceptable.
According to the recently introduced Frost & Sullivan report, "The
Personal Communications Network Market," the demand for personal communications products and services derives from a growing need for personal mobility and accessibility.
Alto also presented Roland Soohoo's paper "Microwave and mm-wave Hardware for New Generation PCN Radio Links." The talk described hardware configurations for point-to-point
personal communications network (PCN) radio links that support high data rates and use sophisticated modulation schemes.
The
personal communications network is another piece of the unwiring of America.
This book describes the emerging
personal communications network (PCN) and personal communications services (PCS) and discusses the recent technological history leading np to this communications revolution.
These modulation schemes are available for a number of communication system formats, including PHS, personal digital cellular (PDC), PDC_H, NADC, terrestrial flight telephone system (TFTS), GSM,
personal communications network (PCN) DCS1800, cordless telephones - second generation (CT2) and digital European cordless telecommunications (DECT).
