Why do the different mobile phones not interfere with each other even they have same antennas ?

Question by Name N: Why do the different mobile phones not interfere with each other even they have same antennas ?
Could you please tell me if antenna is getting all the signals but the circuit decides the frequency(as u mentioned), then why there is no interference between the cellphones in the same cell, although they have the same circuits?
I mean me and my friend in the same room using the same phone and calling people. I know for each mobile different frequency allocated. But hoe the phone differ thet. Dont they have the same circuit all the time?
Regards,

Mobiles phones use “packet technology” to transmit data. Each “packet” of data contains an “address” of the phone it is being sent to. Your phone decodes ONLY those packets addressed to it.

The cell phone takes the sound waves of your voice and converts them to a digital signal. Those digital signals are then assembled into a “packet” of data. At the same time, the “packet” is given an address of the closest cell tower.

All the computers attached to the cell towers determine which phone the “packet” is going to, and the computers on the ground route the packet through the easiest network path to the cell tower closest to the phone being called. that cell tower then transmits the packet to the cell phone.

Since the “packet” has the “address” of only ONE specific phone, ONLY that phone can decode the packet. ALL of the other packets that may be floating around, even those on the same frequency, are ignored.

iOS 7 mobile substrate not functioning?

Question by Vassily: iOS 7 mobile substrate not functioning?
I jailbreaked my iphone 5 recently. Installed some tweaks that are working under ios7 (activator beta for ios7, swipeselection, and browserchooser). After a while, the tweaks stopped functioning (and they are not visible in the settings app). After some research, I realized that this malfunctioning was due to the “mobile substrate” that is not working.
What should I do? Wait for the update that evasion is working on? Or restore my iphone and rejailbreak it?

Both Saurik and the Evad3rs team announced that Mobile Substrate is not (currently) working on iOS 7. The Evad3rs team released the jailbreak without giving Saurik time to prepare either Mobile Substrate or Cydia.

Mobile Substrate is a development layer and safety net that is required to run tweaks on Jailbroken devices. Without Mobile Substrate, tweaks will not work – and if they do, they’re extremely UNSTABLE.

On December 24 at around 8:00 AM EST, Saurik released an update to Cydia for iOS 7. As of the 24th, Cydia 1.1.9 is the latest version of Cydia which is iOS 7 compatible. In the release notes, Saurik said that “he needed to get [Cydia] out so he could move onto Substrate development…” This release only happened a few days after the initial iOS 7 jailbreak was announced. Therefore, I would guess that mobile substrate won’t be too far behind. You can probably expect to see a mobile substrate update by January 1, 2014 (or earlier – maybe even a week).

What should you do? I think the best thing to do is to wait it out. A mobile substrate update is on its way and should be here soon. It’d just be more trouble to rejailbreak later. Besides, Cydia has more than just tweaks! Jailbreak apps, mobile terminal, SSH, and things like that all still work (if they’re updated for iOS 7). You can also search Google for a list of “iOS 7 compatible jailbreak tweaks /apps”

Mobile technology is any device that runs on battery power and contains electronic components.

Examples of Mobile Technology: laptops, cell phones, PDA’s, GPS units, MP3 players.

It has increased our ability to communicate, to navigate, to do business at a faster pace. It allows me to talk to my mom in a different city while I’m taking the bus home from University.

In countries where it’s hard to put in telephone poles, mobile technology has allowed communities to get on the internet and get in touch with the rest of the world.

It allows mothers with small children peace of mind when leaving their babies at daycare, knowing that they can be reached if there’s an emergency.

GPS allows people to navigate through unfamiliar locations with ease.
