3G Deployment in the Bay Area

2. Preface
On September 25th
2001,when asked if I would like to work on the San Francisco
Bay Area 3G project I eagerly accepted the challenge. I was asked to assist in
developing the policies and procedures to implement guidelines for the deployment of
this new emerging technology.
Since then I have come to identify problems beyond the scope of my initial
thoughts. These problems affect everyone involved, AT&T Wireless, Bechtel, and
Bechtel’s contractors. I was told that the objective of this project was to deploy a quality
product, safely, and on time. After working in the trenches since, I’ve watched this
project slowly move forward, identifying issues including material shortages, less than
desirable working conditions, and degradation to the existing network. As Bechtel
pushes to meet their August 1st
2002 deadline to have this new network up and on the
air, I continue to see setbacks that threaten the quality of our existing TDMA network,
and therefore the ability to maintain the level of service our customers expect. After 2
and a half months of work, there are roughly only 40 of 728 sites waiting only for
equipment that as of yet, is not here. While I do not doubt Bechtel’s resolve to meet
this deadline I wonder how we, as a team, can improve our productivity 5 times and still
achieve our goals while we continue to be plagued with delays.
The solution that I propose, in and of itself, may not improve our performance 5
fold, yet I feel it addresses many of the concerns of all parties involved. The procedure
I tested last night, January 21, 2002, at Site 710 in the Upper North Beach District of
San Francisco, while still in need of refinement, gives me the hope that together as a
team, we may, 1) Improve Safety, 2) Guarantee AT&T Wireless remains the industry
benchmark for personal communications, and 3) Increase contractor productivity and
performance.
Before last night’s test, the contractors, representatives from Bechtel and I
agreed that while my proposal is not without sacrifice for all parties involved, the
reward far outweighed the risk.
Upon that I proceeded to test, what I feel, will dramatically improve and
streamline the deployment of 3G in the San Francisco Bay Area.
3. The Problem:
Implement 3G in the Bay Area ensuring we make our deadlines in a safe manner
with minimal impact to our existing network.
Current situation:
After two months of implementation we are behind schedule having completed
the RF and Electrical portion of work at roughly 40 of 728 cell sites. With the August 1st
deadline to have the entire network operational, considering our present situation,
contractor productivity needs to increase 500%. In addition, continual setbacks
including the unplanned replacement of antenna feed lines, delays in material
shipments, lack of available spare parts and degradation of the existing network further
hamper our progress.
Up to this point, numerous process improvements have been implemented and
although they have helped, we continue to fall behind more and more with every
passing day.
The Challenge:
While I have been assured that the necessary manpower to meet these goals will
be sourced before the deadline, these additional work forces will be subjected to the
same conditions, cold weather, fatigue, and poor lighting. And while the familiarity of
the Bay Area’s unique cell site configurations continues to improve, we are running out
of time to get new contractors ahead of the learning curve.
The challenge for us as a team, AT&T Wireless, Bechtel, and its contractors is to
develop a plan to address these workplace concerns, increase productivity, maintain
quality and identify problems sooner, overcoming them with swift, resolute action so
“we can turn the tide”.
The Plan:
I propose we divide the contractor’s workforce into three separate teams. The
first will identify problems that may delay the cutover of 2G equipment or the
installation of 3G equipment. The second team will perform any and all work on the
existing 2G TDMA system. This 2G team will guarantee that when the final team
arrives, they can focus strictly on the installation of 3G equipment. Moreover, we must
be allowed to perform as much work as possible outside the 10pm-5am-maintenance
window. This will ensure better overall working conditions resulting in, improved safety
and increased productivity while maintaining network quality.
4. How the plan works:
The contractor segregates his workers into three specialized work groups. The
first group requires only two workers. This group will identify any problems with the 850
MHz Antenna System, and Antenna Feedline for 1900 MHz. This allows Bechtel to
order feedline (if necessary) before the installation of the 3G antenna system so it is on
hand when the antenna crews arrive at a later date.
In addition, any problems with the 850 system can be corrected before the site is
modified, ensuring the ongoing performance of the existing 2G network.
The second group performs all necessary work for the modification of the 2G
system. This includes the installation of duplexers, diplexers, and jumpers which are
cut into the receive antennas, one at a time, and tested to ensure they are performing
correctly. Once this group is ready, AT&T Wireless personnel will assist in the 2G
cutover.
This cutover will be performed during the day. Using BRIO and similar traffic
statistic analysis programs a daytime maintenance window will be identified. This
window will allow AT&T Wireless, in conjunction with the contractor to cut over the 2G
system, one sector at a time, to clear the primary transmit antenna feedline for 3G use.
Since the cutover disrupts only a portion of the site, communication between Bechtel,
Contractor and AT&T Wireless is maintained.
This cutover should not exceed 15 minutes per sector and preliminary testing of
this procedure resulted in typical cutover times of 4 minutes or less (see attached
document” 710 Cut” for printout details). Comparison of traffic stats for non-peak
daytime hours shows an overall improvement in billable airtime when compared with
current method of taking the entire site down for 5 hours or more at night.
Once the cutover has been performed, the contractor crew will verify the integrity
of the open antenna feedline, allowing for replacement cable to be ordered should a
problem exist, before the 3rd
and final contractor crew arrives.
After verification of the feedline system, the antenna crew now performs the
necessary work for 3G. Working in the Bechtel Approved RF Safety Zone, the unused
TDMA antenna is removed and replaced with the1900 MHz antenna. The main
antenna feedline connectors are upgraded to DIN type and all necessary sweep trace
test are completed. All of this work can now be performed outside the maintenance
window during daylight hours.
5. How the Plan is implemented:
The contractor segregates his workforce into 3 teams. The first team comprising
of 2 workers will be referred to as the Presweep Team, the second group, the 2G
Cutover Team, will clear all lines needed for 3G. Finally the 3G Antenna Team will
remove unused 850 MHz antennas, Install new 3G antennas, and where necessary
run new coax antenna feedline.
6. 1. The Presweep Team.
Their job is to meet at the site with the Bechtel Field Coordinator. The
contractors will review the RF Design form for the particular site with the Bechtel Field
Coordinator. Any discrepancies will be redlined on the RF Design sheet. These
changes should note any additional materials required to insure that contractors are
provided with the components necessary to perform the job while updating quantity
changes for proper tracking.
If the design requires duplexing of an 850MHz primary transmit line onto a
receive line, the contractor will identify the appropriate receive antenna and verify that
there is currently no duplexer attached. If there is a duplexer already existing the
Bechtel Field Coordinator will contact the AT&T OMC and request they temporarily
block down the appropriate connected devices (TX2 or CDPD As defined in attached
document “2G Presweep Procedures.vsd”). Upon confirmation that the devices have
been confirmed as blocked (visual as well as verbal from AT&T OMC technician) the
Bechtel Field Coordinator will indicate on checklist the appropriate sector and devices
blocked (this checklist not yet defined). At this point the contractor will remove the
receive jumper from the appropriate antenna feed line. (Since all Ericsson Macro RBS
equipment is equipped with antenna diversity, this is not service affecting). The
contractor will then perform a sweep of the existing 850MHz antenna system. This
sweep will be saved for submission with the Bechtel Contractor Site Submission
Packet. The contractor will record the highest return loss value and frequency for RX
BAND 824-849 MHz in appropriate fields of the Antenna Data Card (refer to attached
document “ADC Form.xls”) The contractor will then record the same measurements for
the TX BAND 869-894 MHz. If return loss in either band exceeds 18.00dB the
contractor notifies the Bechtel Field Coordinator and marks the ADC Form “Antenna
results” section FAIL (refer to attached document “2G Equipment Testing for 3G
Implementation” for parameter definitions). Also, Bechtel Field Coordinator records
“FAIL” with return loss measurements and feedline identity on his checklist and notifies
AT&T Wireless of problem with existing antenna system. Otherwise the contractor
records “PASS” in this section.
If the RF Design sheet requires this receive line be diplexed for 1900MHz use,
and access to antenna feedline at the antenna is available through reasonable means,
the second contractor will identify the appropriate antenna through color code
identification AND RF signal verification with Wiltron S331B (this procedure is already
defined in Bechtel documentation). Upon confirmation of correct antenna, contractor at
feedline will remove weatherproofing from connector and install a 50-ohm termination-
allowing contractor in the shelter to sweep feedline at 1900MHz. If the coax tests within
specifications (Bechtel documentation) The contractor records value and frequency of
the highest return loss for 1900 MHz band as well as “PASS” in the “Feedline Results”
section of ADC Form and records the sweep trace for later submission to Bechtel.
The contractor reconnects the upper antenna jumper to the antenna feedline as
verified in the shelter using the Wiltron and the connector is weather proofed. The ADC
7. Form (with first half completed) is attached to the main antenna feed line at the shelter
before the antenna jumper is reconnected to the RBS.
If the other feedline does not require testing or no duplexer is installed, the
Bechtel Field Coordinator reviews checklist for blocked equipment before proceeding
to next antenna. If equipment was blocked for that sector, The Bechtel Field
Coordinator contacts AT&T OMC to restore devices for that sector.
This procedure is repeated for all antennas requiring either a duplexer or diplexer
be installed.
*An ADC Form with the first half completed including Technician Name,
Employer, Date, Site, Sector, RX Antenna #, Sweep Analysis Results and
PASS/FAIL results to be attached to any antenna requiring Duplexer or
diplexer installation. All results must be PASS for “Antenna Results” and either
PASS or N/A for “1900MHz” before contractor 2G Daytime Cutover crew will
be allowed to proceed- This responsibility to lie with the Bechtel Field
Coordinator!
*PLEASE NOTE: During test implementation of this procedure at Site
710- Upper North Beach – two technicians working together performed this
process for all 824-894 MHz tests on 6 antennas in approximately 15 Minutes !
8. 2. The 2G Cutover Team
The 2G Cutover Team will prepare the site for 3G antenna installation. Their
responsibilities will include the installation and verification of all necessary duplexers,
diplexers and related antenna jumpers for 850MHz use. They will also ensure that all
necessary antenna lines needed for 3G antenna installation are tested once they've
been cleared of 850 MHz equipment, and diplexers (if used) are working properly at
both 850MHz and 1900MHz bands.
This 2G Cutover Team should consist of no less than two and no more than four
workers. Upon receipt of materials this contractor team will mount duplexers and
diplexers on the overhead ladder rack and prepare all necessary jumpers from the
duplexer to the main antenna feedline, as well as the transmit and receive jumpers
from the duplexer to the RBS equipment. Once these jumpers have been prepared, the
2G Cutover Team will disconnect the appropriate existing receive antenna jumper from
the main antenna feed line. Only one RX antenna is to be disconnected at any time
and the duplexer receive path must be reconnected to the RBS before disconnecting
another RX antenna (Since Ericsson RBS Equipment uses diversity receive, this is not
service affecting).
The antenna jumper from the duplexer to the main antenna feedline will then be
attached and using the guidelines outlined in the attached document (2G Equipment
Testing for 3G Implementation) the contractor will sweep the receive output of the
duplexer through the new antenna jumper. Once its performance has been verified as
better than -14 dB of return loss, the contractor will record the frequency and value of
the highest return loss reading on the second half of the ADC Form in the "Duplexed
RX 824-849 MHz" portion attached to the main antenna feedline. Once the receive
jumper passes, the contractor will connect the receive jumper to the RBS equipment,
restoring antenna diversity. The contractor will repeat the procedure for the transmit
jumper connected to the TX side of the duplexer, recording his readings in the
"Duplexed TX 869-894MHz" portion located on the right hand portion of the ADC Form.
Provided the transmit jumper tests better than -14 dB of return loss through the
duplexer, the sector is now ready for 2G Daytime Cutover by AT&T Wireless
Personnel.
AT&T Wireless Personnel will assist in the daytime cutover of the duplexer to
clear the primary transmit line for 3G use. From the analysis of traffic data (see
attached documentation 2G Daytime Maintenance Window Study) the 2G Cutover
should be performed between 1:00PM and 2:00PM. The 2G Cutover Team will be
required to contact the appropriate AT&T Wireless Manager for the particular region
prior to 10:00 a.m. Once an AT&T Wireless Field Technician arrives on site the
Technician will verify that the ADC Form has been filled out properly in all fields for all
duplexer outputs.
Once the AT&T Wireless Technician has confirmed the performance of the
transmit jumper through the duplexer (enforced through periodic spot checks and
verification of the ADC Form) the technician will notify the AT&T Wireless Network
Control Center of the sector maintenance to be performed. Then, using the Site Block
9. Tool developed by Network Support Systems (NSS) the tech will block the appropriate
sector for "2G Daytime Maintenance Window Cutover". Running the MTCCP
command in WINFIOL, the technician will verify that all traffic within that sector has
cleared. If traffic has not handed off to neighboring sectors after 4 minutes, the AT&T
Wireless Technician will disconnect the main receive lines to the RBS equipment
forcing traffic off of that sector. Once it has been verified that it is safe to proceed, the
existing transmit jumper will be removed, and replaced with the transmit jumper from
the duplexer. When the RBS equipment has been reconnected to the transmit side of
the duplexer the AT&T Wireless Technician will then deblock the sector using the Site
Block Tool. AT&T Wireless Personnel will then run an MTCCP printout to confirm all
devices within the sector have been restored, as well as an MBVTP printout to verify
VSWR readings for that sector. AT&T Wireless in conjunction with the contractor will
proceed to the next sector until all sectors within that site are completed.
This procedure should take no more than 15 minutes per sector and during trial
test, sector outage times were typically less than 4 minutes (please see attached
documentation "Results from Site 710 2G Daytime Cutover Procedure").
Once the primary transmit antenna feedline has been freed for 3G use, the 2G
Cutover Team will then confirm the location of the unused transmit antenna (using
Bechtel documented procedures and color code verification). Upon confirmation, of the
correct transmit antenna feed line, (provided that reasonable access is available) the
contractor will remove the weatherproofing and disconnect the unused transmit
antenna jumper. After installing a test load, the integrity of the antenna feed line will be
confirmed by sweep trace test at 1900 MHz. This sweep of the 3G antenna feed line
will then be stored for later submission to Bechtel in the contractor submission package
(this is already a Bechtel requirement). Additionally a completed ADC Form should be
attached to the antenna feedline indicating readings for 1900 MHz. If the coax feedline
tests within limits for 1900 MHz, the contractor should record "PASS" in the "1850-
1990MHz TERM" field on the ADC Form. Should a problem be indicated during the
1900 MHz sweep test the contractor will perform a Distance to Fault sweep of the
feedline. The ADC Form should also be updated with the frequency and value of the
highest indicated return loss as well as "FAIL" in the appropriate box on the ADC Form.
The contractor will then notify the Bechtel Field Coordinator that a problem with the
antenna feed line exists so appropriate action taken to order replacement coax before
the arrival of the 3G Antenna Installation team.
Should the sector require the installation of a diplexer, this procedure should be
repeated for the other receive line. Once diplexers have been installed on each end of
the main antenna feed line, performance of both the 850 MHz 1900 MHz outputs of the
diplexer located within the shelter should be verified. Using the Wiltron S331B, sweep
trace tests should be performed for both bands, and their results recorded in the
appropriate fields on the ADC Form.
Otherwise if all antenna feedlines have passed all sweep tests for the 1900 MHz
band, the site is now ready for the installation of 3G antennas.
10. 3. The 3G Antenna Team.
The 3G Antenna Team is responsible for installation of all remaining equipment
to implement 3G. This includes the removal of existing unused 850 MHz antennas, as
well as installation of new coax line, TMA's, and 1900 MHz antennas. The 3G Antenna
Team will also replace the existing N Type connectors with DIN type.
Since the majority of sites allow for this work to be performed in the Bechtel
approved RF Safety Zone, 3G antenna installation can now be carried out during
daylight hours, rather than the 10:00 p.m.- 5:00 a.m. Maintenance Window.
Once 3G antenna installation has been completed this final contractor crew will
prepare jumpers to connect to the BTS equipment, finish all necessary sweep trace
tests, and install ID tags on the antenna jumper lines. Upon their completion, the site
should be ready to go, waiting only for the installation of 3G BTS radios.

20. Results from Site 710 test of 2G Pre-Sweep Procedure &
2G Daytime Cutover Procedure
Per time stamp in switch at 9:31PM I ran a status report to see how many calls were active within the
sector. There were 3 calls up and running.
Per my watch I began blocking sector B using the automated site block tool at 9:31:30PM
I continued to run MTCCP until all calls were cleared at 9:33:30PM
As soon as sector was clear of traffic I requested the TX jumper be removed from the filter, and the
TX side of the Duplexer be attached in its place. Upon successful cutover I began to deblock sector
B.
By 9:34:15PM all devices in the sector were on the air.
Total sector outage time was 2 minutes 45 seconds.

Per my watch I began blocking sector C using the automated site block tool at 9:35:30PM
Once blocked, 9 calls remained. I continued to run MTCCP. After approximately 5 minutes, I request
the receive lines be disconnected to force the three remaining calls to another sector. Shortly
thereafter, I realized the one remain call was my conversation with the Bechtel Field Coordinator.
I ended the call and after his call cleared in C sector I called him back on his cell phone to reconnect
both receive lines, and have the TX line cut over. It was 9:42:30PM.
At 9:45:27PM upon successful cutover I began to deblock sector C.
By 9:45:50PM all devices in the sector were back on the air.
Total sector outage time was 10 minutes 20 seconds.
