What is a Personal Communication Service?

Personal communication services (PCS) is the term for cellular phone technologies that enable mobile communications. Also known as digital cellular, PCS offers advanced wireless communication capabilities to boost the functionality of traditional cellular and fixed-line telephony networks.

Personal Communications supports a variety of SNA client application programming interfaces. These include high-performance routing (HPR) and dependent LU 6.2 requester support.

Voice

Voice communication is the ability to transmit sound via a spoken word or signal. This allows people to interact with technology simply by speaking, enabling hands-free requests and reminders. It also facilitates speech-to-text dictation programs and voice recognition devices such as Amazon’s Alexa or Apple’s Siri, which can take instructions and respond with text.

Broadband personal communications services, or PCS, is the radio telecommunications service utilizing the 1850-1990 MHz spectrum range for digital mobile phones and other services. This includes CDMA code division multiple access and Global System for Mobile (GSM) communications.

PCS can be incorporated into other programs as an embedded object, showing up as an icon or appearing as a window within the other program when actuated. It can also be activated through a script; Visual Basic or LotusScript are supported by Personal Communications, and any ActiveX/OLE automation scripting language can be used to produce compound documents with a PCS embedded object.

Data

PCS is a wireless service that offers voice, messaging and data transmission. It uses end-to-end digital technology and is more secure than analog cellular technologies. PCS systems also use a wide spectrum of frequencies to provide greater capacity and coverage than traditional cellular networks.

Sometimes referred to as digital cellular, personal communications service utilizes time division multiple access (TDMA), CDMA and GSM technology. It was designed to enable extensive mobility by offering users connectivity as they move between different cell-based networks in a geographic area.

PCS sessions can be embedded or linked into other programs as part of a compound document, with the appearance that they are one entity. This can be done through a script, such as Visual Basic or LotusScript, which is used with any ActiveX/OLE automation scripting language. In this way, Personal Communications can be activated when the container program is started, or it can appear to read host entry screens automatically, for example.

Messaging

In technology terms, messaging enables loosely coupled communication. It allows programs to send information to a service that handles it and then conveys it to other systems without the sending program knowing the destination system’s address or even its existence. This is similar to postal and shipping services, where letters or packages are handed off to a carrier, not to the recipient.

Personal Communications supports a number of client application programming interfaces (API) for host terminal emulation and client/server SNA applications. These include AnyNet SNA over TCP/IP, High Performance Routing (HPR), and Dependent LU Requester (DLUR).

PCS, sometimes called digital cellular, uses wireless technology to add voice, data and paging capabilities to existing AMPS cellular phone networks. It relies on a network of geographic areas divided by frequency bands to provide continuous phone coverage as the mobile user moves between different cells. PCS also provides high-speed data transmission on demand to supplement voice service. It is based on circuit-switched TDMA, CDMA and GSM technologies.

Location Services

Location services (also known as geospatial technologies) combine information and communication technologies to offer mobile users the right service at the right time. They use a device user’s geographical position to automatically or query-initiated provide information and/or services, such as maps, navigation software, and social networking services.

Apps that can access your location use GPS, Wi-Fi, Global Positioning System (GPS) networks, Bluetooth devices and cellular networks to determine your approximate position. They can share that information with other apps and websites, as long as you allow them to do so.

When Location Services is enabled, iOS will periodically send the locations of nearby Wi-Fi hotspots and cellular towers to Apple to help build crowd-sourced databases of those locations. These location data points aren’t associated with any personal identifying information. If you don’t want to continue to share this type of data, turn off Location Services when not in use. You can also change the level of detail an app has access to by tapping Settings and reviewing an app’s terms, privacy policies and practices.
