There is a big difference over the edge pdf regrinding and reconditioning. Regrinding” is just sharpening a cutting edge.
We have and do what it takes – everyday! Try us and see for yourself. We’ll get you more out of the tools you use! Defense, Heavy Equipment, Tool Manufacturing, Medical and Energy Industries. EDGE sign shown in notification bar on an Android-based smartphone. GPRS networks, making it easier for existing GSM carriers to upgrade to it.
EDGE is a superset to GPRS and can function on any network with GPRS deployed on it, provided the carrier implements the necessary upgrade. EDGE requires no hardware or software changes to be made in GSM core networks. EDGE-compatible transceiver units must be installed and the base station subsystem needs to be upgraded to support EDGE. If the operator already has this in place, which is often the case today, the network can be upgraded to EDGE by activating an optional software feature. EDGE produces a 3-bit word for every change in carrier phase. This effectively triples the gross data rate offered by GSM.
This increases the probability of correct decoding. This means it can handle four times as much traffic as standard GPRS. In GPRS, the Coding Schemes CS-1 to CS-4 specify the number of parity bits generated by the cyclic code and the puncturing rate of the convolutional code. In GPRS Coding Scheme CS-4, no convolutional coding is applied. Coding Schemes MCS-1 to MCS-9 take the place of the Coding Schemes of GPRS, and additionally specify which modulation scheme is used, GMSK or 8PSK. GPRS, while MCS-5 through MCS-9 use 8PSK. 3 is used, and puncturing is used to achieve the desired code rate.
The headers are coded more robustly than the data. As shown in TS 44. MAC header, RLC header, RLC data unit and spare bits. The RLC data unit represents the payload, the rest is overhead.
The radio block is coded by the convolutional code specified for a particular Coding Scheme, which yields the same PHY layer data rate for all Coding Schemes. Cited in various sources, e. EDGE in a number of ways. Further the signal quality is improved using dual antennas improving average bit-rates and spectrum efficiency.
The main intention of increasing the existing EDGE throughput is that many operators would like to upgrade their existing infrastructure rather than invest on new network infrastructure. Mobile operators have invested billions in GSM networks, many of which are already capable of supporting EDGE data speeds up to 236. Considerable research and development happened throughout the world for this new technology. A successful trial by Nokia Siemens and “one of China’s leading operators” has been achieved in a live environment. Evolved EDGE will ever see any deployment on live networks. With Evolved EDGE come three major features designed to reduce latency over the air interface. On average, this requires 20 ms for one way transmission.
