iPod Battery Replacement: The "Ins" and "Outs"

After the iPod hit the market, it seemed as if Apple could do no wrong. Now everyone, regardless of their software camp, could enjoy one of Apple's classically cool and beautiful toys. It wasn't until about 12 months after the launch, when it came time to replace the first set of batteries, that Apple hit a bump in their groove.

The iPod isn't built for easy battery replacement like a cell phone. In order to replace the battery, the casing must be completely removed, exposing all of the internal components and introducing risk of damage.

Apple initially offered a battery replacement service for $249. They later offered a one year extended warranty for $60 that covers the battery. However, it's important to note that when Apple sends the replacement, it will be in a refurbished model iPod, not your original. Today you can find qualified repair shops to replace the battery for as little as $59 or do-it-yourself kits between $19 and $39 depending on the model.

The caution with the do-it-yourself (DIY) kits however, is that the iPod wasn't designed for the average user to change the battery. Plenty of people have been able to change their batteries without problem while countless online forums divulge a long list of complications faced as a result of users trying to change the battery.

Many specialty repair shops will do the replacement for little more than the cost of the battery itself. Some offer additional incentives such as iPod Mod's consumer-friendly lifetime battery replacement program. Under the program, the company will replace the battery once a year for life. Even better, your iPod is back in your hands within 48 hours with 30% more power than Apple's original battery.

Should you choose to replace the battery yourself, there are a few tips you'll want to keep in mind:

-Some models like the Nano require soldering directly onto the board. Be sure to check the details of the battery replacement before sending off for a DIY kit.

-Have a small thin tool on hand to pry apart the casing. Once the screws that hold the case together are removed, you still need to apply some force to open it and reveal the circuitry. Many have damaged their cases by trying to pry their iPods apart without the proper tools. Many replacement batteries come with special tools to help pry the case open.

-When disconnecting the battery, don't remove the rubber pad located on the hard drive.

Regardless of the battery complications, people still love the fun and freedom that the iPod offers. Do a little research before deciding how to handle your battery replacement as it's a routine that you'll need to repeat about once every year. Even if you're not thrilled about the fact that your unit will need to go through major surgery every year, there are customer-friendly iPod specialty companies available to make the process smooth and simple.

Wireless Network

Wireless network pass on to any kind of computer network that is cable less and generally linked with a telecommunications and based on IEEE 802.11. Wireless Network can implement between nodes without any wire and remote information transmission system uses the radio waves, at the physical level of the network. There are several benefits of Wireless Network such as file sharing, Internet connection sharing, multi-player games, Internet telephone service, Computer mobility, and No unsightly wires. 802.11 support networking bandwidth and have an array of choices such as 802.11b, 802.11a,802.11g, 802.11n also known as Wi-Fi technologies and designed for precise networking programs. The hardware requirements of a Wireless network are Network adapter, Repeater, Network hub, and Modem.

There are different types of Wireless Networks such as LAN in which radio signals are used instead of wires and transmit data from one Pc to other Pc in the same network as it is Wi-Fi is a wireless network that enables connection to internet with WiFi functionality. it produced radio waves that can be picked up by WiFi receiver and fixed wireless data is also type of LAN that can be connect more then one building with the mean of sharing .The MAN have ability to connect several local area networks and a term WiMax used to represent wireless metropolitan area networks and Mobile devices networks contains Global System for Mobile Communications which is called GSM network and mainly used for cellular phones, Personal Communications Service is a radio band used to set up PCS and D-AMPS is an upgrade version of AMPS.

A Wireless network containing basic setup and to use a wireless network you have to need a networking card and Kernel config require IEEE 802.11 wireless network driver, Hardware Access Layer and ample Rate control algorithm. Wireless to crypto support modules .There are different kind of protocol used in a Wireless network, it has routing protocol such as DSDV, AODV, B.A.T.M.A.N, PWRP, DSR, OLSR, OORP, TORA,HSLS and The Ad-Hoc Configuration Protocol and Proactive Auto configuration.

Wireless network faces much security threat due to some reason as Spread spectrum used in LAN not very protected because the spreading codes openly therefore companies can intend the 802.11 mechanism and a hacker can easily demolish the security as it is a hacker can still snuffle the SSID. The use of DHCP in wireless network is also helpful for hacker to spoil your files because it automatically assigns IP addresses to users as they become active and hang the system. Generally networking security attack divided into two types which are passive and active .Passive including Eavesdropping, and Traffic analysis and active including Masquerading, Replay, Message modification, Denial-of-service. Loss if integrity and confident also cause of lack of security so it is necessary for all organizations that they make their system more secure even than before as no one can interrupt in it.

Mobile Ringtone Market is Booming

Aside from the obvious telecommunication market and usability of mobile phones another sub-market has developed from the mobile industry boom. This sub-market is the mobile phone ringtone market. The growth of this submarket came as an unexpected, pleasant surprise as nobody would have thought that mobile ringtone downloads could surpass the download rate of Apple’s iTunes, but it did. Individuals caught in the wireless lifestyle trend want to put a sense of their personality and individuality in their mobile handsets, so they personalize their phones through their ringtones.

The mobile phone ringtone market is definitely on a major growth spurt. Generic ringtones that are installed by default on the mobile phones are now passé, people like to have specific tones set to sound their phones whenever someone calls or messages them. Mobile phone ringtones usually cater to the youth market as they constantly update their mobile ringtones based on the current hit-song in the market which, as we all know, is ever changing.

The ARC Group of consultants have reported that the mobile ringtones revenue of 2007 amounted to US$ 3.5 billion worldwide. ARC Group noted that the profit made by mobile ringtone sales in 2007 increased by 40% since 2002.

Mobile ringtones are typified into 4 different categories. The most basic and the predecessor of all the modern-sounding ringtones is the Monophonic Ringtone. Monophonic Ringtones are tones that have no note harmonies. These tones are capable of playing only one note at a time. The sound produced by monophonic ringtones is usually based on the main melody. If you play the piano, and you play your right hand’s notes without the left hand accompaniment—this is how a monophonic ringtone will most likely sound like.

The second category of ringtones is the more advanced Polyphonic Ringtone. A Polyphonic Ringtone is basically a music file that is capable of storing more than 2 notes. These tones can play note harmonies and they add depth and tonality to the quality of sound of the ringtone. A polyphonic ringtone usually sounds like an instrumental song.

True Tones or Real Life Ringtones make the third category of ringtones. They are an upgraded version of polyphonic ringtones. Real Life Ringtones are capable of storing note harmonies with voices and other patterns of sound.

The fourth and most recent category of ringtones is the Master Ringtones. Master Ringtones are basically compressed clips of sound files. Most master ringtones are saved in either the mp3 or mp4 format.

The market leaders for mobile ringtone downloads based on geography and region are Europe and Asia. Sales of mobile ringtones in these areas reach around US$ 4 per download. It has been said that more money has even been made with ringtone sales as compared to music CD singles. It’s not much of a wonder that recording companies have such as EMI and BMG in the United States have tied up with mobile telecommunication companies like
Verizon. Universal Records and Sony Records in Europe have plans to team up
with T-Mobile as well.
