About Packet/Sakis.

 
Hello All. This is my first Blog. The idea of writing this blog is what I thing of a personal notepad or log of what’s next or what’s going on in Telecom field. Telecom, driven by packets, managed by packets and served by packets.

I am the CEO of Dialect Technologies, Inc., a leading VoIP Provider focused on businesses, in the tri-state area of NY, NJ and CT. Dialect also provides fixed wireless solutions, voice and data, to enterprises and small cities.

See you around.

______________________________________________________________________________________________________

a packet is a formatted block of data carried by a packet mode computer network. Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a series of bytes, characters, or bits alone. When data is formatted into packets, the bitrate of the communication medium can better be shared among users than if the network would have been circuit switched. By using packet switched networking it is also harder to guarantee a lowest possible bitrate.

Packet

Packet switching is a communications paradigm in which packets (discrete blocks of data) are routed between nodes over data links shared with other traffic. In each network node, packets are queued or buffered, resulting in variable delay. This contrasts with the other principal paradigm, circuit switching, which sets up a limited number of constant bit rate and constant delay connections between nodes for their exclusive use for the duration of the communication.

Cellular Digital Packet Data (CDPD) uses unused bandwidth normally used by AMPS mobile phonesbetween 800 and 900 MHz to transfer data. Speeds up to 19.2 kbit/s are possible.

Developed in the early 1990s, CDPD was large on the horizon as a future technology. However, it had difficulty competing against existing slower but less expensive Mobitex and DataTac systems, and never quite gained widespread acceptance before newer, faster standards such as GPRS became dominant.

3GPP LTE (Long Term Evolution) is the name given to a project within the Third Generation Partnership Project to improve the UMTS mobile phone standard to cope with future technology evolutions. Goals include improving spectral efficiency, lowering costs, improving services, making use of new spectrum and refarmed spectrum opportunities, and better integration with other open standards. The LTE project is not a standard, but it will result in the new evolved release 8 of the UMTS standard, including mostly or wholly extensions and modifications of the UMTS system. The architecture that will result from this work is called EPS (Evolved Packet System) and comprises E-UTRAN (Evolved UTRAN) on the access side and EPC (Evolved Packet Core) on the core side. – Wikipedia.
