new mobile sit's qualification.At the mentioned project we had subcontractor to create new mobile sites in this process they executed civil part of site and then tower Erection after that equipment installation and then integration site .So at all of this processes

i was one of supervisors that must investigate them and issue & sign finally qualification documents.At this project we involved with Huawei & Nokia Equipment RF Engineer

Tarahane Ertebatate Namvar(TEN) co - Tehran, IR - June 2011 to August 2015 Tehran, Iran Jun 2011- Aug 2015

TEN is a multi task corporation with the various contracts that covers mobiles site network projects like as rollout, operation & maintenance, optimization . Mobile sites needed to operation & maintenance team that must cover all issued problems and returning site condition to the normally condition at the least time. I was first one of this team and after 3 years became team leader.We followed any issue like as power issue or transmission problem other RNC and RAN issued problems and resolved them to return site to normal condition.

Also as a RF engineer I had tasks including:

search area issuance,candidate assessment,redesign of mature network areas to maximize performance, performing Macro/Micro/in-Building cell design including antenna selection and placement, Improve network performance,utilizing knowledge of CDMA, LTE, microwave to contribute in network design. Also in a P25 Land Mobile Radio(LMR) project executing I had a essential role as a RF engineer P25 LMR Engineer

Tarahane Ertebatate Namvar(TEN) co - Tehran.Iran - June 2010 to August 2015 Public safety organizations and government agencies usually are the clients for LMR Service whose goal is to satisfy the complex and evolving mission-critical communication needs of users for interoperable, narrowband Land Mobile Radio (LMR) equipment and systems.

So with execution of Project 25 we could help our clients Technically,The P25 suite of standards has defined three types of systems – Phase 0, Phase 1 and Phase 2 systems

Phase 0 Systems – Phase 0 analog systems are used

by public safety entities (and others) in bandwidths ranging from 12.5 KHz to 30 KHz. The common

elements of these systems are FM analog modulation and analog-based signaling techniques such as

CTCSS and CDCSS

Phase 1 Systems – Phase 1 systems are defined by the TIA102 series of the P25 standard documents. The

earliest standard documents were related to the CAI

(Common Air Interface) using the following

technologies:

• Frequency Division Multiple Access (FDMA)

spectrum which is divided into channels, each

carrying one voice path

• 12.5 KHz channel spacing which generally uses 25 or 30 KHz and is twice as efficient as traditional analog channels.

Phase 2 Systems – Phase 2 systems represent the

next step in the migration process to achieve

improved spectrum efficiency, with a 4:1 voice path spectrum utilization improvement over the original 25 KHz FDMA technologies. Phase 2 Time Division

Multiple Access (TDMA) systems comply with the

FCC’s voice spectrum efficiency rule of one voice

path per 6.25 KHz equivalent bandwidth – providing two voice paths in a 12.5 KHz channel.

An open P25 interface connects one network component with another. The P25 standard defines the electrical characteristics the connection must have, the signals that will be sent between the components over the connection, and what each signal will mean. The P25 suite of standards specifies eight open interfaces between the various components of an LMR system. Data Center Technician

Kosar Bank - Iran - September 2013 to June 2014
