CDMA Mobiles creating revolution in mobile technology

CDMA technology is lesser used technology amongst the two i.e. GSM and CDMA. There have been two major network-providers Tata and Reliance. Recently, MTS has also joined hands with them and has come out of lucrative schemes to create a revolution in competition.

CDMA or Code Division Multiple Access is as smart a technology as GSM mobile networking. Originally known as IS-95, it was developed by Qualcomm and enhanced by Ericsson. It is characterized by small radius but high capacity. CDMA is a form of spread-spectrum signaling and its modulated coded signal has much higher bandwidth than communicated data.

CDMA technology is lesser used technology amongst the two i.e. GSM and CDMA. There have been two major network-providers Tata and Reliance. Recently, MTS has also joined hands with them and has come out of lucrative schemes to create a revolution in competition.

Companies like Samsung, Motorola, LG, etc have been targeting their customers with attractive prices and schemes. An average CDMA handset is very cheap and usually come with cheap connection prices. Initially they could not create their market-hold, due to their lesser subscribers. But now, they are as popular as GSM mobiles.

This technology is more popular in suburbs and villages, where the cost of operating a CDMA handset is quite low. In one such scheme, talking from mobile to mobile with same service provider was almost negligible and hence quite affordable. On the other hand, users have to invest in mobile and connection both for utilizing this service.

Mobile services have improved upon their network and this is the treason that almost every second person utilizes the services with quite an ease.

Mobile Forensic Extraction Tools

Cell Forensics Aquisition Tools

A list of cell forensics tools for extracting information from mobile telephones held by law enforcement. Free tools are the Blackberry Device Manager and BitPim. Hardware for purchase are the Cellebrite UFED, Secure View, and Susteen / Datapilot XRY.

Last week, we looked at cell forensic extraction tools and why they are even important for local law enforement.. A serious opportunity to finalize cases is available if you are collecting mobile forensics from your targets.

Cell forensic extraction devices have made made what was at one time a exceptionally painful process much simpler because they automate the process In this article, we will summarize a few of these mobile forensic extraction tools; in some investigations, they are free of charge, but in others, they cost a little money.

If you desire to do something that is wearisome and time consuming, try the physical extraction approach to mobile forensics information. Teaching on the subject is difficult to come by. In addition, the amount of customized hardware and tools required present challenges for even the most seasoned professional analysts.

Over in the UK, detectives are disassembling the telephones and extracting data directly off of the information boards themselves; so, we know the manual approach can work. However, given the rapid evolutions we see in the mobile phone forensics extraction tools market, I would suggest that the manual approach is no longer the optimal choice.

Tools for Aquisition that are Free of Charge

Quite a few sites host free tools for analysts to use to accomplish mobile device forensics. Often times, the tools only work with a limited number of mobile telephones; but they can still be helpful. A tool that we recommend is Bitpim. By permitting you to view and extract information for analysis on many CDMA phones from Samsung, LG, Sanyo, and others, Bitpim accomplishes the rudimentary cell forensics aquisition undertaking quite well.

An additional free tool focused on Blackberry smartphones can be located BlackBerry.com.Analysts be able to download the Blackberry Device Manager, back up the device, and move forward with viewing the information. The IPD file format downloads some handy cell forensic data like SMS, call records, emails, email content, and calendar events on the device. However, the IPD format alone is not viewable. To really use the information, you must have another tool that costs $19.95 called the ABC Amber Blackberry Converter.

Extraction Tools that Are Automated and Cost Money

– One of the most commonly used tools is the Cellebrite UFED (Universal Forensic Aquisition Device). The UFED automatically parses and extracts information from over 2,000 different cell telephones. , including CDMA telephones (like the ones that run on Verizon and Sprint) and GSM telephones (AT&T & most international carriers). In truth, that is 95% of the cell phones out there. Their new UFED Physical Pro model also permits detectives to access deleted content.

– The XRY or XACT tool by Micro Systemation is another tool of not that is widely used around the world. Touting support for almost 1000 phones as well as the new Android, this cell forensic tool is becoming a must for crime analysts.

– Finally, the Secure View by Susteen / Data Pilot is another viable optoin. It is a small computer that permits the analyst to extract mobile forensics and execute basic analysis on the go.

Many circuits inside the phone will remain accurate provided they are not attached to a power source when wet.

4. If your mobile set is a GSM carrier, then please withdraw your SIM card. By doing this you can save your significant data as well as your contact list. To some people contact list could be more worth saving than the phone itself. You dont need to heat up your sim card. Just keep it dry and leave it aside until you need to link your phone to your cellular network. This important step of removing sim is not applied to CDMA carrier phones.

5. Next step is to dry your phone. Try to remove as much of the water as early as possible, so you can save it from getting into the phone. Vigorously shake your mobile but dont throwover it on floor while shaking it, then use a towel or paper towel to slowly remove as much of the remaining water as possible. Dry the excess moisture by hand.

6. Remove any covers and external connectors to open up as many grooves, crevices, gaps in the phone as possible. Idea is to remove water from every part of your mobile set.

7. You may use vacuum cleaner to remove excess water and dry your set. Try to avoid hair dryer for this purpose, as this may allow moisture further into the small components, deep inside the phone. If moisture is driven deeper inside, deep parts and circuits may show corrosion and oxidation as minerals from liquids are deposited on the circuitry. If you are using a hairdryer it may temporary carrythrough your problem, but this will eventually allow component failure inside the phone. In each accessible area use vacuum cleaner for at least 15 minutes and remove all residual moisture. By adopting this method your mobile can get into working condition within just 30 minutes. Dont keep the vacuum too close to the phone, as a vacuum can create static electricity, which can creat further damage.

8. If you still feel that there is some water inside, then you may go for a substance which has a high osmolality for water to help draw out moisture, i.e this substance can absorb water more quickly. You may use uncooked rice overnight. The rice would absorb any remaining moisture. Instead you may use desiccant. Desiccant can remove moisture better than rice.

9. Now keep the mobile set on absorbent towels, napkin, or other paper for atleast one day. Idea is the same, remove excess water and humidity from cell phone. Check absorbent towels, napkin, or other paper every hour for 4 to 6 hours. If you note any moisture again, just go for vacuuming step and desiccant steps.

10. Now you have reached the final step.Test your phone. After twenty four hours, first check it with battery and see if it works. If your phone does not work, check it without battery by plugging it into charger, if this works, you need a new battery. If not, take your mobile to an authorized dealer. Sometimes they can remove the problem. Please tell them what actually has happened with your mobile.

Analysis of three kinds of packet loss in wireless network environment

The TCP congestion control mechanism Cisco 1941-SEC Cisco 1941-SEC is the only cause of congestion for data loss, due tothe characteristics of wireless channel, the wireless network environment of large amounts of data due to switching, channel fading, interference and discarded, in this case if the TCPcongestion control, will reduce the data transmission rate is not necessary, cause bandwidth utilization rate is not high, the system delay increases, throughput decreases. 1 random packet loss (Random Loss) The traditional TCP congestion control mechanism is designed for wired networks. Almost negligible caused by bit errors and link error data loss. But in a wireless network, data loss is caused by fading. The IS-95 service based on CDMA data, 1% ~ 2% is the random packet loss. The 2 burst loss (Burst Loss) Burst loss in a very short time, result in the loss of many consecutive data. It is caused by thesignal fading. Wireless LAN as an example, on a mobile host, all traffic it (inflow and outflow) is through which is connected with the base station route. When a mobile host from coverage of a base station is removed, it needs another base in the exercise of its information to register. After all communication is accomplished through the new base station. However, when the switch, a series of data through the primordium station submitted to the mobile host packets will be lost.Therefore, you can switch to lead to the occurrence of burst loss events. 3 packet reordering (Packet Reordering) When the receiving end receives the order and the sending end to send the order of the packets are not at the same time, to packet reordering. The same is the wireless LAN as an example, reorder packets associated with switching. When a mobile host from a base station is switched to another base station, sent to the mobile host or is sent from the mobile host packets through the base station route of new information. Because the data packet transmission will experience a different RTT on different paths, resulting in packet cannot order delivery at. Cisco 2901 Cisco 2901
