Published on Mar View Download In order to accommodate technological changes and enhance system performance in the State of Connecticut, T-Mobile plans to modify the equipment configurations at many of its existing cell sites. Please accept this letter and attachments as notification, pursuant to R. Section j, of construction which constitutes an exempt modification pursuant to R.
Section j b 2. In compliance with R. Section j, a copy of this letter and attachments is being sent to the chief elected official of the municipality in which the affected cell site is located. As part of T-Mobile’s L project, T-Mobile desires to upgrade their equipment to meet the new standards of 4G technology. The new equipment will allow customers to download files and browse the internet at a high rate of speed while also allowing their phones to be compatible with the latest 4G technology.
The changes to the facility do not constitute modifications as defined in Connecticut General Statutes significantly changed or altered. Rather, the planned changes to the facility fall squarely within those activities explicitly provided for in R.
The overall height of the structure will be unaffected. The proposed changes will not extend the site boundaries. There will be no effecton the site compound. The proposed changes will not increase the noise level at the existing facility bysix decibels or more.
The changes in radio frequency power density will not increase the calculated”worst case” power density for the combined operations at the site to a level at or above the applicable standard for uncontrolled environments as calculated for a mixed frequency site.
For the foregoing reasons, Northeast Site Solutions NSS on behalf of T-Mobile, respectfully submits that t gbx-6516ds-vtm proposed changes at the referenced site andreq exempt modifications under R. Please feel free to call me at Sincerely, Denise Sabo Mobile: Emily Hannon tower owner mailto: October 19, Max Usage: Number October 19, A. Number October 19, Page 1A.
The tower and foundation can support the equipment as described in this report. If you have any questions or require andew information, please contact American Tower via email at Engineering americantower. Please include the American Tower site name, site number, and engineering number in the subject line for any questions.

This information may consist of, but is not necessary limited, to: It is the responsibility of the client to ensure that the information provided to A. Engineering Service, PLLC and used in the performance of our engineering services is correct and complete.
In the absence of information to the contrary, we assume that hbx-6516ds-vym structures were constructed in accordance with the drawings and specifications and that their capacity has not significantly changed from the “as new” condition. Although every effort is taken to ensure that the loading considered is adequate to meet the requirements of all applicable regulatory entities, we can provide no assurance to meet any other local and state codes or requirements.
If wind and ice loads or other relevant parameters are to be different from the minimum values recommended by the codes, the client shall specify the exact requirement. All services are performed, results obtained, and recommendations made in accordance with generally accepted engineering principles and practices. Engineering Service, PLLC is not responsible for the conclusions, opinions and recommendations made by hbx-6516ds-vym based on the information we supply.

Wireless Carriers and Paging Services use different frequency bands each with different exposure limits, therefore it is necessary to report results and limits in terms of percent MPE rather than power density.

Therefore, members of the general public would always be considered under this category when exposure is not employment related, for example, in the case of a telecommunications tower that exposes persons in a nearby residential area.
Because each carrier will be using different frequency bands, and each frequency band has different exposure limits, it is necessary to report percent of MPE rather than power density. Since T-Mobile is proposing highly focused directional panel antennas, which project most of the emitted energy out toward the horizon, all calculations were performed assuming a lobe representing the maximum gain of the antenna per the antenna manufactures supplied specifications, minus 10 dB, was focused at the base of the tower.
For this report the sample point is the top of a 6 foot person standing at the base of the tower. For all calculations, all equipment was calculated using the following assumptions: These Channels have a transmit power of 30 Watts per Channel. These Channels have a transmit power of 60 Watts per Channel.
This channel has a transmit power of 30 Watts. For each RF path the following losses were calculated. This is rarely the case, and if so, is never continuous. The maximum gain of the antenna per the antenna manufactures supplied specifications minus 10 dB was used in this direction. This value is a very conservative estimate as gain reductions for these particular antennas are typically much higher in this direction.
This is based on feedback from the carrier with regards to anticipated antenna selection. The maximum gain of the antenna per the antenna manufactures supplied specifications, minus 10 dB, was used for all calculations.
Values in this database are provided by the individual carriers themselves. The anticipated maximum composite contributions from the T-Mobile facility as well as the site composite emissions value with regards to compliance with FCCs allowable limits for general public exposure to RF Emissions are shown here: This is based upon values listed in the Connecticut Siting Council database for existing carrier emissions.
