Term
ESN
Definition
Electronic Serial Number - A unique, unchangeable 32-bit binary number embedded by the manufacturer that identifies each wireless communications device. (Except those that use GSM technology, which use an IMEI instead.)
Term
IMEI
Definition
The International Mobile Equipment Identity (IMEI) is a number unique to every GSM and UMTS mobile phone. It is usually found printed on or underneath the phone's battery and can also be found by dialing the sequence *#06# into the phone.
Term
GSM
Definition
GSM -- Groupe Speciale Mobile
(Global System for Mobile Communications)
This set of standards is widely used in Europe for cellular communications. The audio encoding subset of the GSM standard is best known to computer users because its data compression and decompression techniques are also being used for Web-phone communication and encoding WAV and AIFF files.
Term
CDMA
Definition
Code Division Multiple Access. In a CDMA system, each voice circuit is labeled with a unique code and transmitted on a single channel simultaneously along with many other coded voice circuits. The receiver uses the same code to recover the signal from the noise. The only distinctions between the multiple voice circuits are the assigned codes. The channel is typically very wide with each voice circuit occupying the entire channel bandwidth. This system used 1.23 MHz wide channel sets. The full vocoder rate is 8.55 Kbits/sec, but voice activity detection and variable rate coding can cut the data rate to 1200 bits/sec. A very robust and secure channel can be established, even for an extremely low-power signal-theoretically, the signal can be weaker than the noise floor.
Term
EVDO
Definition
Evolution Data Only/Evolution Data Optimized (often abbreviated as EVDO, EV-DO, EvDO, 1xEV-DO or 1xEvDO) provides fast wireless broadband access (3G) internet service directly to your laptop/cellphone. It is an evolution of CDMA2000.
Term
HSDPA
Definition
High-Speed Downlink Packet Access is a new mobile telephony protocol and is sometimes referred to as a 3.5G (or "3½G") technology. In this respect it extends WCDMA in the same way that EV-DO extends CDMA2000. HSDPA provides a smooth evolutionary path for Universal Mobile Telecommunications System (UMTS) networks allowing for higher data capacity (up to 14.4 Mbit/s in the downlink). It is an evolution of the W-CDMA standard, designed to increase the available data rate by a factor of 5 or more. HSDPA defines a new W-CDMA channel, the high-speed downlink shared channel (HS-DSCH) that operates in a different way from existing W-CDMA channels, but is only used for downlink communication to the mobile.
Term
WIFI
Definition
Short for wireless fidelity and is meant to be used generically when referring of any type of 802.11 network
Term
AKU
Definition
Adaptation Kit Update

AKU 1.1 contains the Car Bluetooth additions so the device will transfer phonebook and other items to your in car Bluetooth kit.

AKU 2.0 updates include Microsoft’s Messaging and Security Feature Pack (MSFP) and an updated Comm Manager.

Microsoft Messaging and Security Feature Pack (MSFP): This enables business users to easily stay connected wile on the move, allowing Direct Push Email, Wireless Calendar, Contacts, Tasks, Global Address List (GAL) Lookup and Security Policies. This means that emails, calendar, contacts and tasks are automatically sent and received from mobile devices.
