When we talk about antenna then we need to understand about antenna installation and specially about antenna downtilting.lets assume that antenna installed then how you can change its position. Its two type, left-right = its called azimuth change. up-down = its called tilt change. Lets understand from start. ANTENNA INSTALLATION Antenna installation configurations depend on … Read more
Isolated reuse technology refers to 1*3 or 1*1 reuse with short reuse distance and severe interferences, radio frequency hopping technology has to be adopted. The aggregate of hopping frequencies needs to be far more larger than the number of TRX (more than twice), MA, HSN and MAIO parameter are used to avoid frequency conflict. Let’s … Read more
Throughput or bandwidth that LTE was taken for the physical layer for the MCS under the pick or sustainable conditions. Throughput, individual users might be depends both on the MCS allocated (a function of characteristics and conditions of the user channel) and the requirements of other users sharing the channel resources (as arbitration Scheduler). Similarly, … Read more
Front to back ratio is an important characteristic of directional antenna antenna. Is the ratio of power radiated from a corner with maximum radiation radiation levels at 180 degrees (the back of) from that point. Front to back the ratio is usually expressed in terms of dB, i.e. the signal at the rear of the … Read more
LTE is designed to operate in environments where there are peripheral interventions. Link performance degrades as the C/I (i.e. Carrier interference ratio) is reduced, however, it may be acceptable in places with zero or negative C/i. every site and sector LTE systems operating on the same channel so that they can receive interference from all … Read more
Management of external interference from all other sites/sectors improves system performance and capacity. Intervention studies are used to examine areas that have significant peripheral interaction problems. Lighting and intervention studies are analysis to determine what sites/sectors of intervention problem (i.e. determining what sites/sectors may be providing too much interference in the field or sites/sectors that … Read more
