Consequences of 3G

Consequences of 3G

Since 3G is a very new technology, it is easy to expect that there are some drawbacks as well. More and more developments are being conducted by various manufacturers worldwide, to better cater to the needs of consumers. You can take advantage by getting to know your gadgets and tools from the inside out.

Here are some details on the possible consequences and if you should consider getting your own 3G mobile unit.

Some Backfires

Some devices, particularly the iPhone 3G, has no instant messaging options or MMS. You then take out the advantage of sending and receiving photos via MMS. There is inadequate or missing expandable memory too. A number of devices may appear in a couple of variants, namely the 8 and 16 GB built-in memory.

The non-detachable battery also is a disadvantage, since you have to put two and two together to get the needed energy. There are also limited service provider selections, so you do not get to pick your personal ISP.

Instead it is taken and sold via a certain MSP Mobile Service Provider. The price of some 3G tools also may be very expensive for a number of individuals. You should learn how to compare your options on the internet and through local dealers.

From GPRS to UMTS

Several network elements can be used again, starting from GPRS network. The included ones are HLR or home location register, VLR or visitor location register, EIR or equipment identity register, MSC or mobile switching center which is vendor dependent, AUC or authentication center, GGSN or gateway GPRS support node and SGSN which is vendor dependent or serving GPRS support node.

If you are starting from GSM or global service for mobile communication radio network, you cannot use some elements again, such as BSC or base station controller and BTS or base transceiver station. These can stay inside the network and be used in two network operations wherein 2G and 3G networks exist together. At this occasion the network migration and recent 3G terminals are also present for use within the network.

Some Functionalities

The UMTS network shows and introduces some recent network elements that work as specified by 3GPP, namely MGW or media gateway, base station or node B or RNC or radio network controller. The functions of SGSN and MSC will vary when going toward UMTS.

In a GSM system, the MSG controls all the circuit switched operations such as linking A and B subscriber through the network. In UMTS, the MGW or media gateway is responsible for all types of data transferred in both the pack switched networks and the circuits. MSC and SGSN manage operations of MGW. The nodes will be named again to GSN and MSC servers.

Discussing Security

Compared to its 2G predecessors, 3G networks are a lot more secure. It allows the UE to authenticate the network it is attaching to, allowing the user to be certain that the network is the right one and not just a mere impersonator. 3G networks usually make use of the KASUMI block crypto, compared to the old A5/1 stream cipher. Several major weaknesses in the cipher have been discovered, however.

There is also end to end security provided when application frameworks like IMS are accessed.

3G Compatibility

3G Compatibility

3G technology is the most recent released for mobile phones. More and more individuals all over the globe are converting to the new platforms because of faster connectivity, easier accessibility and better performance overall. You can enjoy faster downloads and viewing for music and videos, play 3D games and do video conferences with others.

Here are more details about the compatibility among networks and how well you can get ahead.

Compatibility with Other Networks

UMTS networks can be managed and operated using GPRS or GSM networks. The systems will apply a number of frequency bands, so that mobiles and BTSs will not interfere with one another.

Some vendors will claim their core network as UMTS compatible, such as RNC, BSC, MSC, SGSN and HLR, although several operators will choose to create an entirely independent and unique UMTS network. A number of the most recent GSM BTSs can also have parts of the UMTS radio and share a single rack.

The UMTS specifications are created, leaving maximum compatibility between UMTS and GSM systems. During the late 2002, there are also multi and dual band phones that can be applied in UMTS and GSM networks. Over time, the phones will have the capacity to do handovers from one network to another.

The Transition

There may not be a transition time from UMTS up to the current system, since the systems of GSM will continue to function constantly in the next 10 years. A number of 1G networks are actually still functional and running until this time in some areas of the world. The only limitations for operators are the terms of the GSM license and the personal preferences of clients. The networks of UMTS will be given as an addition to the mobile platform.

Licensing and Status

Most GSM operators failed or missed to obtain a UMTS license, such as Denmark, France and the United Kingdom. These are not totally counted out. Current operators have big assets, a huge customer base, retail network, BTS site locations, image, transmission systems and several others. These give them the advantage of making deals with license holders of 3G technology. Some of the best examples are Telia with Tele2 in Sweden and Hutchison 3G in the UK.

In the United States, a number of operators have chosen CDMAOne, CDMA2000 1x EV-DO, CDMA2000 and CDMA2000 3X. Others have even chosen GSM1900, EDGE or D-AMPD-EDGE. There are new cellular frequencies allocations that may have been delayed or postponed, leading operators to use the current frequencies that naturally stop the available capacity at a certain point.

Other Details

The TD-SCDMA 3G system has been constantly tested in China. There is license allocation and the possibility to adapt to other 3G technologies. When 3G licenses are given out or issued, the Beauty Contest term may be used. This means that the government will require every applicant to give a plan on how they intend to build a network and manage other business regarding 3G.

There are several aspects to consider when planning, such as asking how many jobs can be made, how many domestic products are consumed, what kind of plan in terms of financing will lead to success, what type of services can be availed of and how other less fortunate areas can also take advantage of 3G technology.
