GLOSSARY

TERMS

DEFINITION

3G

Third generation. Applies to wideband mobile services and

 

applications. A standard with faster transmissions and the

 

ability to roam globally.

 

 

802.11A family of wireless specifications developed by a working group of The Institute of Electrical and Electronics Engineers. These specifications are used to manage packet traffic over a network and ensure that packets do not collide - which could result in loss of data - while traveling from their point of origin to their destination (that is, from device to device).

802.11b

Well-accepted standard for Wireless Local Area Networks

 

(WLANS). Optimized for the unlicensed 2.4Ghz band, with

 

speeds up to 11Mbps.

802.11g

Pending WLAN standard comparable to 802.11a (for

 

speeds up to 54Mbps) but operating in the 2.4Ghz

 

spectrum.

Access Fee

A monthly charge for the ability to connect to a wireless

 

network (see provider plans). This is assessed monthly

 

whether the mobile device is actually used or not.

Airtime

Total time that a wireless device is connected or in use for

 

data/voice.

Bandwidth

A measure of network resource used for transmitting and

 

receiving data. Measured in kbits/sec. Can be thought of as

 

the size of a data "pipe".

Bluetooth

A wireless PAN (personal area network) geared for home

 

and office that allows devices to connect over a short range

 

(10m) without a line of sight. Uses 2.4 GHz range at 720kps

 

within 30-foot range.

BPS

Bits per second. Measure of transmission speed or

 

bandwidth.

Cache

A cache is a place to store something temporarily.

 

Frequently used data/information can be stored without

 

being downloaded again from the original server.

CDMA

Code Division Multiple Access is a multiple access

 

technique, which uses code sequences as traffic channels

 

within common radio channels.

Cradle

Mobile devices (PDA, phone) are rested on a cradle to

 

perform synchronizations.

Downlink

Direction of data transfer from the network to the mobile

 

device.

Dual mode

A term that describes a wireless device or system that can

 

support two different protocols.

Encryption

Phantomfiber's Wireless Framework is the only true end-to-

 

end 128-bit encrypted wireless solution commercially

 

available. The solution is based on 128-bit Elliptic Curve

 

Cryptography provided by Certicom (the industry leader in

 

secure wireless information delivery) and provides a secure

 

delivery method that parallels the most secure internet

 

transaction servers in existence today. The WAP gateway is

 

removed from the underlying model that delivers Covers

 

Wireless to the end user.

OS Devices specifications

Palm OS devices, integral to the evolution of mobile computing, emerged in the late 1990s, characterized by their unique operating system and innovative features. The Palm OS, developed by Palm, Inc., was specifically designed for handheld devices and PDAs (Personal Digital Assistants), establishing a foundation that would influence many subsequent mobile operating systems.

One of the key features of Palm OS devices was their user-friendly interface. The system employed a simple, menu-driven navigation scheme that utilized a stylus for interaction on a touchscreen display. This touchscreen capability was pioneering at the time, allowing users to effortlessly navigate through applications and settings. The devices often featured a compact design, with physical buttons for shortcuts, enhancing usability.

Palm OS devices were renowned for their productivity applications. The Calendar, Contacts, and To-Do List applications helped users organize their tasks and schedules efficiently. Additionally, the inclusion of third-party applications through the Palm Software Development Kit (SDK) allowed for the expansion of functionality, giving rise to a diverse ecosystem of apps that catered to various user needs, from finance to entertainment.

Another notable characteristic of Palm OS was its synchronization capabilities. Users could connect their devices to desktop computers via USB or serial connections to sync data, ensuring that their information remained updated across devices. The introduction of the Palm HotSync technology simplified this process, allowing users to transfer contacts, emails, and documents with ease.

In terms of hardware, Palm OS devices typically boasted small screens, ranging from 160x160 pixels to larger 320x320 pixel displays in later models. Most devices were powered by ARM processors, known for their efficient performance and low power consumption, enabling longer battery life — a crucial factor for mobile users.

Connectivity options also advanced with Palm OS devices. While early models primarily relied on infrared communication, later iterations introduced features such as Bluetooth and Wi-Fi, facilitating easier data transfer and internet access. This evolution allowed users to stay connected and productive while on the go.

Overall, the legacy of Palm OS devices lies in their emphasis on usability, portability, and integration with personal productivity tools. Their influence can still be seen in modern smartphones and mobile applications, marking them as pivotal players in the development of portable technology.
