TECHNOXICATION

Network BUSY??????????????????????????

"The subcriber you have dailled cannot be reached at the moment.Please try again later."

Tired of hearing this?? but have you ever thought of what does "Netwrok Busy" exactly mean? Well if you are a networkin student, am sure you kno more than me. BUt for students like me who aren't pure technical students, this information can be helpful.

Making the whole idea concise, network busy actually means full utilisation of bandwidth. Now wondering what "Bandwidth" means. Bandwith is a measure of available or consumed data communication resources expressed in bit/s or multiples of it (kbit/s, Mbit/s etc). In that case, each of the area is allocated some bandwidth. For instance assume that the bandwidth allocated for Baneshwor is 3.5 Mbit/sec. If a whole lot of people starts makin call at the same time, the whole of this bandwidth is utilised by the user. At the same instance, if i try makin a call at the same area, the allocated bandwidth won't be able to respond my request because its already utilised. Its something like car that has the capacity of 5 people cant take in any more people after 5 people have taken their seats in the car. And thats how you recieve a message in your cell "Network Busy."

These days ,we've been hearing a lot about CDMA and GSM mobile. But do you know that these are the thrown away phones of developed nations like Japan,UK. But the technology used by these phones to utisilsing the allocated bandwith is awesome. These cell phones make efficient use of bandwidth. Consider that i am using a GSM phone, the bandwoidth allocated at my area (Baneshwor) is 3.5. I tried makin a call. At the same instance a girl from bhakta paur also tries to make a call. then the GSM technology enables the utilisation of same allocated bandwidth for two different areas. And thats how GSM mobiles make efficient use of the allocated bandwidth. In that sense, GSM mobiles have fewer network problems.

Now you must be wondering " In Nepal, GSM mobiles also faces much network problems. The reason is Nepal hasn't yet built minimum requirement of networking towers.

 

P:S : "DO YOU KNOW THAT THE BEST NETWORKIN TOWER OF NEPAL IS IN POKHARA AND TO YOUR SURPRISE, ITS NOT THE NTC TOWER, ITS THE TOWER OF MERO MOBILE????"

Correct me if I'm wrong, but I don't believe that the CDMA mobiles are thrown away phones of developed nations. GSM is 2G technology with GPRS approaching 2.5G and it's the branded term referring to TDMA (Time-Division Multiple Access) technology.

While, CDMA(Code Division Multiple Access)which left behind TDMA and FDMA years ago is much advanced, and the top scoring technology phones today in the world as time and frequency reuse is not a problem here.

Well,I liked the example of a car.

pratima,

Looking a good signal is not only the objective....we had to look the health hazard due the radiation of that signal also.....so while managing the singal strength of the station engineer also have to look all others consequences including the bio-hazard also...
