The 3rd Generation Partnership Project (3GPP) is a collaboration agreement that was established in December, 1998. It's a co-operation between ETSI (Europe), ARIB/TTC (Japan), CCSA (China), ATIS (North America) and TTA (South Korea). The scope of 3GPP was to make a globally applicable third generation (3G) mobile phone system specification within the scope of the ITU's IMT-2000 project. 3GPP specifications are based on the evolved GSM specifications, now generally known as the UMTS system.

The 3rd Generation Partnership Project 2 (3GPP2) is a collaboration agreement that was established in December, 1998. It's a co-operation between ARIB/TTC (Japan), CCSA (China), TIA (North America) and TTA (South Korea). The scope of 3GPP2 is to make a globally applicable third generation (3G) mobile phone system specification within the scope of the ITU's IMT-2000 project. In practice, 3GPP2 is the standardization group for CDMA2000, the set of 3G standards based on earlier 2G CDMA technology.

3GPP Long Term Evolution (3GPP LTE), also known as Evolved-UMTS Terrestrial Radio Access (E-UTRA or EUTRA) or UMTS Long Term Evolution, is specified in the 3GPP release 8. It is a key 3G technology to ensure the competitiveness of UMTS and provide a high-data-rate, low-latency and packet-optimized system. Besides peak data rates of 100 Mbps in downlink and 50 Mbps in uplink, a significant increase in spectrum efficiency and capacity as well as a significant latency reduction are planned. Commercial aspects like costs for installing and operating the network form also part of the requirements.

3GPS (3G Service Provider) is the mobile operator that has 3G license to provide 3G services to customers

Third generation GSM (3GSM) is the combination of the 3G nature of the technology and the GSM standard. The core technology that enables the 3GSM is called Universal Mobile Telecommunications System (UMTS).

3-Way Calling is a feature in voice communications which allows you to conduct a conference call among three parties.

4G is the name for the next generation of technology for high-speed wireless communications that is currently in research and development stage. 4G will be designed for new data services and interactive TV through mobile network.

6lowpan is the IETF working group to define the standards of IPv6 over Low power Wireless Personal Area Networks. 6lowpan is the paragon that is aimed at allowing IPv6 packets to be sent to and received from PANs, more specifically over IEEE802.15.4 (ZigBee) -standard based networks. Likewise, IEEE802.15.4/ZigBee devices provide sensing communication-ability in the wireless domain.

802.11 is a group of wireless specifications developed by the IEEE for wireless local area network (WLAN) communications. It details a wireless interface between devices to manage packet traffic to avoid collisions. Some common specifications include the following: 802.11a, 802.11b, 802.11g, 802.11n, etc.

8802.11a is an extension to IEEE 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band. 802.11a uses an orthogonal frequency division multiplexing (OFDM) encoding scheme rather than FHSS or DSSS. 802.11a, actually newer than 802.11b, offers significantly more radio channels than the 802.11b and has a shorter range than 802.11g. It isn't compatible with 802.11b.

Explanation : Baseband layer, also known as baseband packet, is a physical layer protocol in the Bluetooth protocol stack. The Baseband in the Bluetooth manages physical channels and links apart from other services like error correction, data whitening, hop selection and Bluetooth security. The Baseband layer lies on top of the Bluetooth radio layer in the bluetooth stack. The baseband protocol is implemented as a Link Controller, which works with the link manager for carrying out link level routines like link connection and power control. The baseband also manages asynchronous and synchronous links, handles packets and does paging and inquiry to access and inquire Bluetooth devices in the area.
