Since, Alexander Graham Bell invented the phone; the way of two-way communication had been changed. Now, the people can communicate with anyone they want in just few seconds. By shrinking the distances, phones have made communication fast, easy, and cheap. When phones were invented, they have a bulky size and fixed line connection but continuous technological changes have brought revolutionary changes in the size and mode of the phones.
Now, phones are not that bulky as before. Moreover, cordless phones are also invented to let the people talk when they walk. Initially, they have the frequency of 49 MHZ due to which people could take them up to the distance of few meters from the base unit. But, the cordless phones that are available today have the frequency range of 900 Mhz to 2.4 Ghz, which means the large area can be covered without breaking of voice. With latest cordless phones, you can take it for a large distance from the base unit. You can go to basement, roof, ground floor, or garden to make use of it.
If you compare cordless phones with mobile phones then you will notice that these phones are giving strong competition to mobile phones at factors like appearance, color, functioning, voice quality, and signal frequency. You can now send msg and email with these phones, manage electronic phone book, etc. The only thing where cordless phones are behind from mobile phones is the range, as these phones do not have any base unit.
