The Future Landline Phones

Early Innovations on Landline Phones were Answering Machine, Music-on-Hold and Fax Machines. Later landmines were used for BBS and then DUN (Dial up Networking) Internet. Then came the Big Freeze.

My first data experience before the internet was Delrina WinFax. It helped one of my friends get a job in Europe too. A fax machine was expensive, a Gateway 2000 modem was not. (this modem took me first online at home)

The Future Landline Phones

Cable Internet, Broadband Internet and 3G etc. have pushed the Landline phone in a corner.

I am using Internet on my Landline and it is pretty good. This may not be affordable by all, as a PC or Laptop is needed and the extra Broadband charges. This is just using the same line. My LandLine phone still is UnEvolved.

What i am trying to say is .....Add SMS at least for all Landlines with no extra monthly cost other than the SMS cost. If Possible add a means of slow File Transfer like FAX. A USB port on this device below will do.

This will help many use Data on the Telephone lines without buying a PC or Fax machine. The SMS will be a Super Hit. Voice Mail can alo be done. No Internet required.

The most financially stressed families in the most remote locations can SMS and if possible send their JPG photo or resume over the Normal Phone Connection at only the extra cost of data transfer.

I got my a Landline a few days back, The phone was one with a LCD, It is a very nice phone with a large LCD, but i had trouble using the phone book, as i kept forgetting the sequence.

These Landline phones occupy a prominent position on the desktops of all offices. The CEO, Marketing Manager and Purchasing Officer; or even at the Canteen, we see these phones. The potential for marketing and advertising is good in these, as they are still popular in the office environment. A firm can show its flash presentation or a product catalog, when a customer waits for the despatch details of a product he ordered.

A Landline Phone also may be interesting with a touch screen and built in web browser. This phone can also have the option of WiMax, in areas where it is available.

The Spice in Analog Design

Analog Designers created Spice, Analog Design Professionals are adding their experience in many commercial and free spice EDA tools. When you are creating a new demanding design, a working solution is achieved by combining workbench and simulation work.

The Spice in Analog Design

Lab Test Bench and Breadboard testing needs to be done along with analog simulation. Power and mixed signal design too, needs to be verified on board. This is more true for a new design lab or new engineers. Experienced designers will not make many mistakes as design blocks would be in their collections or in their knowledge base. It is this knowledge that can build the simulator itself, this makes the simulator as skilled as the designer but also limited to his or that firm's experience. In a full digital design, simulation does a more complete Virtual Test bench role.

A simulation tool can help you test the blocks and helps catch some design and concept errors. When you build a live breadboard prototype, some real issues facing your design can emerge.

Spice is a analog design aid and helps mixed design circuit simulation, See the Spice homepage.

SPICE (Simulation Program with Integrated Circuit Emphasis) is a general purpose analog electronic circuit simulator. It is a powerful program that is used in IC and board-level design to check the integrity of circuit designs and to predict circuit behavior. - Wikipedia
