“…Mtel's SkyTel 2-Way is one such example of a system based on Motorola's ReFlex technology. It uses two distinct nationwide networks, a high-powered outbound paging network and a lower powered inbound network both sharing a 50kHz channel on a time-division basis and are linked in to the Network Operations Center [8]. In addition to ReFlex, other systems may be based on Motorola's INFLEXION voice paging and high-speed data technology and possibly some variants of CDPD and Mobitex adapted for the narrower bandwidths.…”

This paper contrasts CellularfPCS mobile data and voice requirements with regards to network performance and architecture to suggest that wide area data and voice are convergent rather than divergent. The paper motivates a further integration of the existing Cellular Digital Packet Data (CDPD) and asynchronous data services with today's TDMAJCDMA air-interface standards and within the network and subscriber unit. The paper concludes by suggesting even more extensive voice and data integration based on the B-ISDN model for the future third generation wireless communications systems.

“…Another major advantage mobile data networks have over cellular is their store-and-forward capabilities. With cellular the wireless terminals have to be continuously attached and working to receive messages, 2 whereas with mobile data messages are stored even when the radio modem is switched off or out of radio coverage, so there is no always-in-contact requirement.…”

“…Continuing development has been done by Eritel AB under the guidance of the MOA and Ericsson Mobile Communications AB. Commercial operation was introduced in Sweden in 1986; since then, a number of networks have been constructed in Europe, the United States, and Australia [2,5]. Only the radio frequency differs, depending on the country: 900 MHz is used mainly in the United States and Canada; most other countries operate in the 450 MHz range.…”

espite the explosive evolution of the cellular 1 industry during the past decade, mobile data networks keep on spreading and providing data services to numerous subscribers all over the world. This is shown by the fact that the most important wireless packet data networks, namely, MOBITEX, ARDIS, and CDPD (cellular digital packet data), are facing increasing activity in many areas, including technical and business. ARDIS (Advanced Radio Data Information Service, a subsidiary of Motorola) is one of the biggest wireless data service providers in the United States. It employs RD-LAP technology and offers wireless packet data messaging service in over 400 metropolitan areas in the United States, Puerto Rico, and the Virgin Islands, and covers about 90 percent of the urban business population [1]. The network was initially created as a private network for IBM and was later made available for public use (as a 50/50 joint venture between Motorola and IBM [2]), offering 19.2 kb/s signaling in 25 kHz channels, wide roaming, robust link layer and coding schemes, and significant overall message throughput. IBM is still ARDIS' largest customer, with more than 12,000 field engineers using the ARDIS network. RD-LAP architecture has also spread to other countries, including Canada and Germany. CDPD [3] is a new technology that has begun to spread, although perhaps not as rapidly as expected [4]. In the first nine months of 1995, CDPD service availability climbed from 12 metropolitan statistical areas (MSAs) to 49, and at the end of the year it reached over 50. CDPD was introduced by IBM as a packetswitching overlay to the existing analog cellular voice network and frequencies. This technology uses idle voice channels to multiplex short data messages and to hop among the available frequencies to find those idle channels. The air interface oper-IEEE Personal Communications
