Core Network of 3G

The Core Network of 3G is divided in circuit switched and packet switched domains. Some of the circuit switched elements are Mobile services Switching Centre (MSC), Visitor location register (VLR) and Gateway MSC. Packet switched elements are Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN). Some network elements, like EIR, HLR, VLR and AUC are shared by both domains.

The Asynchronous Transfer Mode (ATM) is defined for UMTS core transmission. ATM Adaptation Layer type 2 (AAL2) handles circuit switched connection and packet connection protocol AAL5 is designed for data delivery.

The architecture of the Core Network may change when new services and features are introduced. Number Portability DataBase (NPDB) will be used to enable user to change the network while keeping their old phone number. Gateway Location Register (GLR) may be used to optimise the subscriber handling between network boundaries. MSC, VLR and SGSN can merge to become a UMTS MSC.

Basic & Simple Definition to 3G

For common man 3G means

1. Video Call And
2. Fast Speed to download data.

a. The transfer rate for 3G networks is between 128 and 144 kbps (kilobits per second) for devices that are moving fast and 384 kbps for slow ones(like for pedestrians).

b. For fixed wireless LAN, the speed goes beyond 2 Mbps.

c. The first thing you require is a device (e.g. a mobile phone) that is 3G compatible. This is where the name 3G phone comes from - a phone that has 3G functionality; nothing to do with the number of cameras or the memory it has. An example is the iPhone 3G.

At Last 3G provides

• Several times higher data speed;
• Enhanced audio and video streaming;
• Video-conferencing support;
• Web and WAP browsing at higher speeds;
• IPTV (TV through the Internet) support.

Operators launching 3G by 2010 end :

1. Tata Teleservices Ltd.
2. Vodafone Essar Ltd.
3. Airtel

India's largest mobile service provider, Bharti Airtel has announced that it will Launch its 3G Services in 13 Circles across India by 2010 End. Airtel becoming the third private operator after Tata Teleservices Ltd. and Vodafone Essar Ltd. to announce 3G service plans in the world's fastest growing telecommunications market. In May 2010, Airtel succesfully won the bid for 13 telecom zones for INR122.95 billion ($2.77 billion).

Business Wireless Planning Strategy

Business Wireless Planning Strategy Business Planning New entrants to wireless have the daunting task of attracting marketshare in an increasingly competitive environment. Identifying the coverage footprint that will deliver the target ROI hinges on many variables, such as the underlying demographics, competitor footprint, technology capability and target service offering. Subscriber projections, churn, and average revenue per unit (ARPU) are tied closely to system performance and device capabilities. The Wireless Strategy team has built new markets from the ground up, and can turn the multivariate view of technical, marketing, and competitive data into a coherent financial and operational plan. We understand the business of wireless technology. Spectrum Valuation The value of spectrum depends on both business and technical factors. FCC regulations, interference concerns, and existing and future uses of the spectrum and adjacent blocks all affect its viability for various technologies. The technology's true performance will impact the services that can be offered, which will impact the revenue opportunity. Wireless Strategy understands both sides of the equation and can solve for the true value. Strategic Analysis The wireless sector offers unlimited investment opportunities. But which new wireless technologies will be adopted by operators, and which ones will be left by the wayside? Which new wireless entrants or traditional operators will be capable of growing to the next level of performance and deliver significant returns on investment? Wireless Strategy's partners have years of experience in analyzing new technologies and assessing their value to the wireless operator. Technology Briefings We have years of experience in briefing wireless executives on technical subjects, providing clear, concise summaries of the relevant information affecting their business. Investors benefit from our unbiased assessments of technologies and operator performance. Whether explaining the basics of wireless operations or identifying the impact of a new technology on a business, we are ready to brief executives and investors on the best path forward. Executive Services The wireless industry has seen numerous mergers and turbulence in recent years. Wireless Strategy can provide stability through management change by teaming with the business organizations and delivering continuity and focus on company performance. Our partners are well qualified to fill technology and operations executive positions on a temporary or longer term basis. Karl USA

Nokia Dual Sim Phones

Nokia Dual Sim Phones The new dual SIM phones, Nokia C1 (C1-00) and Nokia C2 (C2-00), were affordable entry level phones which will give maximum battery back up. Company claimed that these models, especially Nokia C1, will provide a standby battery time of up to six weeks, the longest ever for a Nokia phone. The Nokia C1 was a basic model without much multimedia features. The users can only use this type for voice and SMS. It has a FM radio, a flashlight and colour screen. The 'call divert' feature will help the users not to miss a call from either of the two SIMs. The users can switch between the two SIM cards by simply holding down a key. Users can buy Nokia C1 at just Rs 1999. Nokia C2 has features like Ovi Mail and Ovi Life Tools, which provides information on healthcare, agriculture, education and entertainment. The memory capacity can be expanded upto 32 GB using Micro SD cards. Users can buy this dual SIM phone at just Rs 2500. Puneet Tripathi

4G Technology : 4th Generation Technology

The fourth generation of mobile networks will truly turn the current mobile phone networks, in to end to end IP based networks, couple this with the arrival of IPv6, every device in the world will have a unique IP address, which will allow full IP based communications from a mobile device, right to the core of the internet, and back out again. If 4G is implemented correctly, it will truly harmonise global roaming, super high speed connectivity, and transparent end user performance on every mobile communications device in the world.

4G is set to deliver 100mbps to a roaming mobile device globally, and up to 1gbps to a stationary device. With this in mind, it allows for video conferencing, streaming picture perfect video and much more.

It wont be just the phone networks that need to evolve, the increased traffic load on the internet as a whole (imagine having 1 billion 100mb nodes attached to a network over night) will need to expand, with faster backbones and oceanic links requiring major upgrade.

4G wont happen over night, it is estimated that it will be implemented by 2010, and if done correctly, should take off rather quickly.

WiMAX Introduction

WiMax (Worldwide Interoperability for Microwave Access) is a wireless broadband technology, which supports point to multi-point (PMP) broadband wireless access.

WiMax is basically a new shorthand term for IEEE Standard 802.16, which was designed to support the European standards. 802.16's predecessors (like 802.11a) were not very acc ommodative of the European standards, per se.

The IEEE wireless standard has a range of up to 30 miles, and can deliver broadband at around 75 megabits per second. This is theoretically, 20 times faster than a commercially available wireless broadband.

The 802.16, WiMax standard was published in March 2002 and provided updated information on the Metropolitan Area Network (MAN) technology. The extension given in the March publication, extended the line-of-sight fixed wireless MAN standard, focused solely on a spectrum from 10 GHz to 60+ GHz.

This extension provides for non-line of sight access in low frequency bands like 2 - 11 GHz. These bands are sometimes unlicensed. This also boosts the maximum distance from 31 to 50 miles and supports PMP (point to multipoint) and mesh technologies.

The IEEE approved the 802.16 standards in June 2004, and three working groups were formed to evaluate and rate the standards.

WiMax can be used for wireless networking like the popular WiFi. WiMax, a second-generation protocol, allows higher data rates over longer distances, efficient use of bandwidth, and avoids interference almost to a minimum. WiMax can be termed partially a successor to the Wi-Fi protocol, which is measured in feet, and works, over shorter distances.
