| | CELLULAR DIGITAL PACKET DATA(CDPD): WHAT MAKES IT RELIABLE? |
 | | CDPD, at 19.2 kbps is not only the fastest available technology, but also the most secure due to its built in RC4 encryption algorithm. | | | It is crucial to develop a secure personal mobile communication environment as secure information flow and privacy are amongst users' top priorities today. | | | In this so-called Age of Information, no one need be reminded of the importance not only of speed but also of accuracy in the storage, retrieval and transmission of data. |

| | Since it is IP-based, it is easy to develop for and easy to integrate into existing applications. | | | Since CDPD in its current state relies on the existing cellular infrastructure and customer bases and is so closely tied to the Internet, it is in a position to see continued expansion among carriers. | | | This is not expensive for average emails and small data transfer applications but for transferring graphics such as those found in a Web page, CDPD costs could skyrocket. |

| | CDPD Manufacturer Identifier Tutorial |
| | The IEEE Registration Authority assigned 'company_id' is the 24 bit high order value of the CDPD Equipment Identifier (EUI-48) defined in the Cellular Digital Packet Data System Specification. | | | The high order 24 bits take the value of the company_id (assigned by the IEEE/RAC) and the following 24 bits are administered by the manufacturing identifier assignee in accordance with policies and procedures set forth by the CDPD Network Information Center. | | | The company_id referenced in your IEEE Registration Authority letter is an integral part of the 48 bit CDPD Equipment Identifier (EUI-48). |

| | Old-time wireless network takes a blow Tech News on ZDNet |
| | AT&T Wireless is also using speedier networks to entice users to switch over. | | | The carrier is just the latest Web or cell phone provider to announce plans to move customers away from CDPD, which was first developed by IBM. | | | Verizon Wireless, the other main CDPD network supplier, is also looking at its network's future, but has yet to make any final pronouncements, according to a representative. |

| | Internetwork Mobility The CDPD Approach Mark S. Taylor William Waung Mohsen Banan |
| | However, no system or technology lasts forever; one of our design goal was that CDPD be readily amenable to evolution. | | | Because we are not radio engineers, we focus on the system and networking aspects of CDPD rather than the radio technologies, which are better described elsewhere. | | | CDPD is a data network which happens to have an RF-based data link resembling Ethernet (but at a lower speed). |

| | On two occasions I have been involved in an evaluation of CDPD technology. | | | First, the suggestion that CDPD works on channels that the voice system is not using. | | | While CDPD is available and being employed by some wireless users, many of the nation's largest wireless users have shied away from it. |

| | A Quick Guide to CDPD |
| | Each channel on a CDPD network can be accessed by up to 30 CDPD users at a time. | | | In the most simple terms, CDPD consists of a laptop computer with a cellular modem transmitting data over the existing cellular telephone network, commonly referred to as AMPS (Advanced Mobile Phone System). | | | The users then move, or "hop" to another available channel and continue their sessions. |

| | Because they often use specialized devices such as dispatching computers with integrated CDPD modems, it may take time for these customers to change over to GPRS. | | | Some time next year, AT&T will begin rolling out EDGE, which should deliver about 118K bps on a handheld device, Pemble said. | | | Both types of services are on all the time and are charged for by number of packets exchanged rather than time spent on the network. |
