Position Title: Field Technician (RX-AIT)
Location: North and South Carolina
Duration:4-6+ Months
Rate: $450-500/Site
Description:
Install, test and integrate RX-AIT (Receiver Air Interface Tray)

transport.Complete NTP document and submit to NCS along with sweeps and
sweep data form
Method of Procedure
1. Log in to OSS bridge upon arrival, document name of analyst on bridge
2. Capture pre photos and document any defects on site prior to arrival
3. Assemble and install trapeze
Trapeze support is required within 18" of hardline termination and 3' span
max thereafter.
4. Replace blank panels on AUX2 cabinet with power entry panels.
Port panel with 1 nine port entry and 3 single will face the RRU pole. The
port entry panel with 4 nine port blocks will face the hardline/GSM route.
5. Install RX-AIT units in 19" rack if not pre-installed.
6. Install power lugs on RMC units and terminate to -48vdc buss on
designated location. Breakers are pre-labeled, lugs to be provided in
install kit.
7. Install RX-AIT internal RF cabling on front of RX-AIT equipment as per
RX-AIT drawing.

Failing sweeps on hardline will require putting a precision load at the end
of the jumper at the hardline and saving sweep. Civil vendor will perform
repair.

amplifiers are functioning normally.
GSM sites with no TMA and no RX-AIT will read app. -112 for main and -112
for diversity.
GSM sites with TMA and no RX-AIT will read app. -106 for main and -106 for
diversity.
GSM sites with TMA and RX-AIT will read app. -100 for main and -100 for
diversity.
These values are accurate for determining RX sensitivity within 3dbm.
