The status of IPR was as follows: • Mixed Raster Content - Xerox may have IPR related to this work and has submitted an updated IPR statement (TR-29/96-11-55 offers this IPR at no charge). • JBIG2 - Xerox may have IPR related to this work with respect to the rendering of JBIG-2 images. LIAISONS ISO/IEC/SC29/WG1/JBIG (Joint Binary Image Group): There has been some progress made on the JBIG-2 working draft. The draft is to be put out shortly and will be made available on the web site to members. In addition, some IPR has surfaced, Xerox has applied for patent rights. The rights are not related to the compression method itself, but there are pending rights related to rendering of JBIG-2 images. There are also plans to make source code available to members and other interested parties. Currently, JBIG-2 is targeted for completion and approval by the year 2000. ISO/IEC/SC29/WG1/JPEG2000 (Joint Photographics Expert Group): TR-29 has decided that a wavelet method will be used for JPEG 2000, based on a coder from the University of Arizona. Work is now proceeding on the architecture which will surround the coder. There is also work ongoing in terms of treating regions of interest in a page in a particular way; the method being used is based on a tiling approach. Xerox and members of the JBIG committee have proposed that the JPEG 2000 committee consider using the Mixed Raster framework as a potential architecture framework. There are two competing architectures related to the architecture itself. There was an interim meeting scheduled in September for St. Petersburg reporting on the results of some experiments. The timetable for this standard is likely to be later than that of JBIG-2. TR-29.4 G. Constantinou (US Department of Defense) reported on results of the TR-29.4 meeting. TR-29.4 is working on extending MIL-STD-188-161-D to support 16 kbit/s operation. Ricoh has worked on the design. G. Constantinou is working on the form of the document. The group is also working on interworking with the new secure phone method (Secure Terminal Equipment [STE]). Interoperability testing regarding STE will take place at Fort Huachuca. The 188-161D changes were submitted to NATO (North Atlantic Treaty Organization) to update STANAG 5000 (NATO Standardization Agreement) over a year ago, but there has been an insufficient number of respondents so far to proceed with approval. COLOR FAX L. McIntyre (Xerox) reviewed results of the SG8 meeting as related to color fax. As noted in the last TR-29 meeting, there has been a change in marker segments (reducing three to one), which results in changes to the T.44 (Mixed Raster Content) document. Since the changes are substantial, it was decided that T.44 should be re- Determined and targeted for final approval in April 1998. The updated T.44 will also contain support for a multi- layer model. In addition, the relevant changes to T.4 and T.30 were also re-Determined. The already published T.4 and T.30 amendments regarding Mixed Raster Content will be declared invalid due to the various changes required. There will be an interim meeting of Question 5/8 in Japan on October 5-8. T.43 (Palletized color) has also undergone delays due to lack of assignment of marker segments by the AFNOR body (Association française de normalisation [French Standardization]). A new registration body was set up in July known as JURA (JPEG Utilities Registration Authority). It is anticipated that JPEG markers will now be assigned in a more timely manner. HF RADIO FAX, PN-4196 There have been some comments received on the re-balloting of PN-4196 (to become TIA-668-A when published). Only Yes votes have been received and the comments appear simple to resolve. 2 Vol. 9.7 Copyright © CSR 1998 October 1998 COMMUNICATIONS STANDARDS REVIEW – TELECOMMUNICATIONS TEST CHARTS AND TEST IMAGES A new T.24 CD (Compact Disk) will be prepared which will take up two CD-ROMs. There is also a table of the percentage of black and white for the images on the disk. V. Cancio (Xerox) expressed concern that some users may incorrectly use the tables to compute the amount of consumables required. Contributions are invited.

  • General Packet Radio Service Third-Generation Wireless Systems Have Yet to Be Deployed
    backed” onto existing GSM wireless networks. The fixed-band- width voice channels of the GSM network are then used for table look up (in the GSM’s Location Register data bases) to obtain a Packet Radio user profile. The signaling and the data traffic are then sent through a separate radio channel that provides 8 timeslots. These timeslots can be used together (to provide a wide-bandwidth channel for a single user) or they can be parceled out among multiple users (to pro- vide several narrow-bandwidth channels). By using multiple channel timeslots together, Packet Radio can provide mobile terminals with transmission speeds ranging from 14.4 Kbits/sec to 115 Kbits/sec. Because Packet Radio can pro- vide a wide range of bandwidths on demand, it can be configured to efficiently handle short “bursty” traffic (such as email and web browsing) as well as large volumes of data. In addition, different levels of service can be provided to different subscribers, billing them accordingly. By Robert Haim Once the user’s data has been sent over the radio channel times- lots, it is packetized for routing over an IP-based Public Land The volume of data traffic has been rapidly overtaking the Mobile Network. (Since these IP-based backbones are used to volume of voice traffic in fixed networks. Data traffic is expected interconnect wireless base stations within a local wireless system, to exceed voice traffic in fixed networks this year, and there is we will call them internal networks.) little doubt that wireless networks will follow soon after. However, second-generation wireless infrastructures were designed pri- Internal networks can be used to carry packets between mobile marily for voice communications, and will need to be replaced terminals within a local area.

    Volume 3, Issue 6, June 2013 ISSN: 2277 128X International Journal of Advanced Research in Computer Science and Software Engineering Research Paper Available online at: www.ijarcsse.com 3G Telecommunication Networks Kajali Bansal Assistant Professor Computer Science & Engineering Dept. Chandigarh University (Punjab) India Abstract: 3G is the third generation of wireless technologies. This comes with enhancements over previous wireless technologies, as high-speed transmission, advanced multimedia access and. 3G is mostly used with mobile phones and handsets as a means to connect the phone to the Internet or other IP networks in order to make voice and video calls, download and upload data and to surf the net. 3G is the successor of 2G and 1G standards. The 3G networks handle the majority of all data transfers for cellular service providers. Keywords: 3G, 4G, 5G, Radio Access Network, Telecommunication, Cellular Network. I. Introduction 3G wireless technology is the convergence of various 2G wireless telecommunications systems into a single global system which includes both terrestrial and satellite components. 3G wireless technology has ability to unify existing cellular standards with CDMA, GSM, and TDMA. 3G has the following enhancements over 2.5G and previous networks: Higher data speed, Video-conferencing support, Enhanced audio and video streaming, Web and WAP browsing at higher speeds, IPTV (TV through the Internet) support transfer rate for 3G networks is between 128 and 144 kbps for devices that are moving fast and 384 kbps for slow ones. For fixed wireless LANs, the speed goes beyond 2mbps. II. Back Ground The first mobile telephone systems (car phone) were introduced in the late 1940s in the United States and in 1950s in Europe.
