The overlapping zones (number of servers) criteria are used to establish the quality of the RF propagation environment from an interference point of view. The goal of the number of servers‘ criteria is to establish dominance and reduce the waste of network resources and degraded network performance that may occur when multiple servers exist in … Read more
Reference Signal Received Quality RSRQ identifies the quality of the Reference Signal. It is defined as the ratio N×RSRP/(E-UTRA carrier RSSI), where N is the number of RB”s of the E-UTRA carrier RSSI measurement bandwidth. The measurements in the numerator and denominator shall be made over the same set of resource blocks. E-UTRA Carrier Received … Read more
Reference signal received power (RSRP) identifies the signal level of the Reference Signal. It is defined as the linear average over the power contributions of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth. Design KPI for RSRP: 10MHz Channel Bandwidth (700MHz & AWS): -113dBm 5MHz Channel Bandwidth (700MHz & … Read more
What may be one of the biggest leaks phones in recent years, come from South Korean analyst, who published the alleged specs of both Samsung and Apple’s upcoming flagship smart phones. More troubling for Apple, including at least the hardware side, the device seems to more powerful handset Samsung handset. Is it enough to tempt … Read more
Sales of Apple’s iPhone 5c were so disappointing that the consumer technology giant will probably reduce the price soon device model or scrap altogether, according to analysts, Alistair Barr reports for USA Today. They just missed. The request was not good, said Gene Munster, an analyst at Piper Jaffray. They will discount and use it … Read more
Here I write about EVDO (HSD) reverse channel in short or summarize defination. The EVDO channels for the reverse connection have a similar structure as for CDMA2000. The reverse link for 1xEV-DO has a structure similar to that for CDMA2000. In EV-DO all signalling is performed on the data channel and this means that there … Read more
A number of channels are transmitted in the forward direction to enable signalling, data and other capabilities to be handled. These channels include the Traffic channel, MAC channel, Control channel and Pilot. These are time division multiplexed. Traffic Channel – This channels uses Quadrature Phase Shift Keying (QPSK) modulation for data rates up to 1.2288 … Read more
The forward link possesses many features that are specific to EV-DO, having been optimised for data transmission, particularly in the downlink direction. Average continuous rates of 600 kbps per sector are possible. This is a six fold increase over CDMA2000 1X and is provided largely by the ability of 1xEV-DO to negotiate increased data rates … Read more
Additional rumors are adding power to the expectations that Apple will finally break out of prison 4 – inch and deliver an iPhone with a resolution close to those offered by its rivals increasingly popular. Apple began with a display of 3.5 – inch, and seemingly reluctantly upgraded to a 4-inch model a couple of … Read more
