WHAT is the difference between land phone and mobile phone?

Answer 1

mobile phone can go just about anywhere, land line is stuck in one spot

Well, I am no expert, but I can probably fill in a few details.

One of the basic things that differentiates GSM (based on TDMA) and CDMA is the way the carve up bandwidth.

Each bit of radio spectrum used by a handset has to be shared with other people in the area. It is more or less the same as multiplexing for normal data land lines.

The major difference between GSM/TDMA and CDMA is in the way they divide up those signals between multiple users.

GSM/TDMA uses a Time Division method. TDMA, in fact, stands for Time Division Multiple Access. Simply put, this means that each device on the local network is allocated a time slice where it "owns" the bandwidth, and it can send/receive its data.

So lets just pick a number and say there are 30 available time slices in a given cycle. Each phone would then get 1/30th of every cycle that it could send and receive data (aka, voice).

CDMA uses a different method, called Code Division Multiple Access. The specifics of how it breaks the cycle up are beyond me, but how it works out is that the phones only get a slice of the bandwidth cycle when they actually need one. So if you are not talking, and the other person is not talking, nothing is transmitted.

With GSM/TDMA, each phone is transmitting and receiving during its slices of the bandwidth cycle, whether it needs it or not.

Since most coversations are comprised largely of silence, the end result is that CDMA phones have to transmit less data. They don't have to send silence, like GSM/TDMA phones do.

This means a few things. More CDMA calls can be fit into a given amount of frequency spectrum (ie. it is more efficient for the network), less radiation is being created from the phone towards the user (you only get radiation when you are talking, basically), and battery power is conserved since the handset only transmits when it actually has something to send.

There are other differences, too, that I can't get into. For one, it is harder to implement a CDMA network. The tower placement is more difficult. Dealing with hills is more difficult than with GSM/TDMA. Things like that.

But in general, CDMA is vastly superior technology. Not surprising since Qualcomm's version of it (that which is used in CDMA and WCDMA phones) is newer technology, even if the basics were in use by the US military as far back as the 40s.

The important thing for me, though, is the SIM card. Had CDMA implemented the use of a SIM card (something it very easily could have done), then the North American market would be very different today, and there would be more CDMA networks in other countries. The SIM card allows people to easily switch phones, and that helps the market.

Anyway, I hope that gives you a basic overvies.simply to say is LAN phone is your phone that's hooked up at home. Mobile phone is also a cell phone that you can carry anywhere in the country with

Answer 4

The differnce is one the appearance. as you can see a land phone is either conected to a cord or from a charger area to the phone. Also the land phone is plugged into a phone jack in your house by a phone cord unlike a mobile phone.

Answer 5

A land line phone is like your home telephone that is hooked up to your homes phone wires. A mobile phone is a cellular phone you get through your wireless provider.

Answer 6

Land line is fixed line, it's the kind of phone that you have in your house...they are fixed line and you cant take it with you everywhere you go...there are some wireles fixed line, but you can't take it too far from the post, right?

Now mobile phone is working the same way, but more flexible when it comes to mobility, you can take it anywhere

Answer 7

A land phone is wired to a base station and trasnmits is data over for the most part fiber optic cables. It is tied to a specific location.

A mobile phone is wireless and transmits its data via microwaves (the energy, not the ovens, though they use it too) to towers arranged in cells (or if you are really lucky and wealthy, to a satellite). Thes phones can move and are only linked ot the networks off which they operate.

Answer 8

A land phone is a telephone you have in your house and it can only be used from the "land line" or phone line at your house.

A mobile phone is exactly that - a 'mobile' telephone, meaning you can take it anywhere and use it almost anywhere.

Answer 9

The "land line" is the one that's plugged into the wall. The "mobile fun" is the one that you stick in your pocket and take with you, also known as your cell phone.

Answer 10

A land line phone is the telephone that is your home; it can not go any where, just stay in your hom.

A mobile phone is your cellular phone that you take w/you when you go places.
