If so, what effect does this consultation 12 have on THESL’s position in this matter? 13 14 RESPONSE: 15 THESL determined its position regarding whether and to what extent wireless 16 attachments should be accepted on its poles independently. THESL has had discussions 17 with various City staff who are aware of THESL’s position on this matter. THESL has 18 not received any substantive feedback or direction from the City of Toronto in this 19 regard. Toronto Hydro-Electric System Limited EB-2011-0120 Interrogatory Responses Tab 1 Schedule 6 Filed: 2011 Sep 22 Page 1 of 1 RESPONSES TO ONTARIO ENERGY BOARD STAFF INTERROGATORIES 1 INTERROGATORY 6: 2 Reference(s): Section 3 (a): “A preliminary consultation meeting between the 3 proponent and the District Planning Consultant and/or City 4 Planning Staff and Toronto Building Division staff is required 5 for all telecommunication tower and telecommunication 6 antenna proposals not exempted from consultation by Industry 7 Canada, before a Telecommunication Tower Review 8 Application and/or Building Permit application is submitted. 9 The purpose of this meeting is to: determine if a Building 10 Permit is required; determine emission levels in compliance 11 with Safety Code Six and if applicable, explore preferred site 12 locations and siting, design & co-location considerations in 13 accordance with this protocol. For telecommunication tower 14 and telecommunication antenna proposals exempted from 15 consultation by Industry Canada, the proponents are 16 requested to provide information to the City on: the nature of 17 the proposal; the location of the proposal; and the emission 18 levels of the proposal in compliance with Safety Code Six.” 19 20 To THESL’s knowledge, were these requirements met by CANDAS, in case of each 21 proposal involving attachment of CANDAS’ antennas to THESL poles? 22 23 RESPONSE: 24 Whether or not CANDAS met these requirements is not within THESL’s knowledge.

Toronto Hydro-Electric System Limited EB-2011-0120 Interrogatory Responses Tab 1 Schedule 14 Filed: 2011 Sep 22 Page 1 of 1 RESPONSES TO ONTARIO ENERGY BOARD STAFF INTERROGATORIES 1 INTERROGATORY 14: 2 Reference(s): Vol1/Exh 2: Affidavit of Adonis Yatchew 3 Section C.4., pages 18 and 19 4 5 Please clarify whether to your knowledge Crown Castle or American Tower, or any 6 company offering similar services with respect to wireless antenna siting services is 7 operating anywhere in Ontario. 8 9 RESPONSE: 10 Given the dominance of Crown Castle and American Tower in the market for wireless 11 antenna siting services in the U.S., there is no reason to believe that a similar market for 12 siting wireless antenna services could not develop in Ontario. Indeed, it is my 13 understanding that Antenna Management Corporation offers sites in Toronto (See: 14 http://www.antennamgt.com/potential-sites). SBA offers sites in Toronto and across 15 Ontario (http://map.sbasite.com/). Please see the Affidavit of Mr. Starkey, page 32, lines 16 1-3. 17 18 Toronto Hydro-Electric System Limited EB-2011-0120 Interrogatory Responses Tab 2 Schedule 1 Filed: 2011 Sep 22 Page 1 of 2 RESPONSES TO ELECTRICITY DISTRIBUTORS ASSOCATION INTERROGATORIES 1 INTERROGATORY 1: 2 Reference(s): Evidence of Michael Starkey, President QSI Consulting 3 4 At pages 26 to 32, Mr. Starkey refers to potential co-location sites in Toronto. Why are 5 these sites considered as potential co-locations sites? Are sites where there are already 6 attachments typically available for use by other attachers? Is there mandatory sharing 7 required for any of these sites? Are these sites, or some of them, controlled by resellers 8 whose business it is to allow multiple attachers? Does Mr. Starkey know if the 25 Public 9 Mobile locations are single or multiple user sites? 10 11 RESPONSE: 12 The evidence refers to thousands of antennas and, at a minimum, well over one thousand 13 potential co-location sites. Industry Canada specifically requires radio spectrum 14 licensees to facilitate sharing of antenna towers and sites, including rooftops, supporting 15 structures and access to ancillary equipment and services and to refrain from causing or 16 contributing to the exclusion of other radio communication carriers from gaining access 17 to sites. [see CPC-2-0-17] Industry Canada also requires anyone who is planning to 18 install or modify an antenna system, regardless of the type of installation or service 19 involved, to consider sharing existing antenna systems and infrastructure. [see, e.g., 20 Industry Canada Client Protocol Procedures CPC-2-0-03] Hence, all carriers are 21 compelled to share sites where possible. Furthermore, antenna site management is a 22 multi-billion dollar business with numerous management companies offering antenna site 23 location and management services throughout North America, including Canada. 24 Attachment MTS-03 identifies roughly 4,000 existing antenna arrays located within 25 25 KM of Toronto's city center. Toronto Hydro-Electric System Limited EB-2011-0120 Interrogatory Responses Tab 2 Schedule 1 Filed: 2011 Sep 22 Page 2 of 2 RESPONSES TO ELECTRICITY DISTRIBUTORS ASSOCATION INTERROGATORIES 1 2 At page 30, lines 10-11 of Mr. Starkey’s direct testimony, Mr. Starkey states that Industry 3 Canada’s ALS database shows Public Mobile has established antennas in 125 unique 4 locations within 25 kilometers of the center of Toronto.

  • SMS), As Defined Within the GSM Digital Mobile Phone Standard Has Several Unique Features
    The Short Message Service (SMS), as defined within the GSM digital mobile phone standard has several unique features: ● A single short message can be up to 160 characters of text in length. Those 160 characters can comprise of words or numbers or an alphanumeric combination. Non-text based short messages (for example, in binary format) are also supported. These are used for ringtones and logos services for instance. ● The Short Message Service is a store and forward service, in other words, short messages are not sent directly from sender to recipient, but always via an SMS Center instead. Each mobile telephone network that supports SMS has one or more messaging centers to handle and manage the short messages. ● The Short Message Service features confirmation of message delivery. This means that unlike paging, users do not simply send a short message and trust and hope that it gets delivered. Instead the sender of the short message can receive a return message back notifying them whether the short message has been delivered or not. ● Short messages can be sent and received simultaneously with GSM voice, Data and Fax calls. This is possible because whereas voice, Data and Fax calls take over a dedicated radio channel for the duration of the call, short messages travel over and above the radio channel using the signaling path. As such, users of SMS rarely if ever get a busy or engaged signal as they can do during peak network usage times. ● Ways of sending multiple short messages are available. SMS concatenation (stringing several short messages together) and SMS compression (getting more than 160 characters of information within a single short message) have been defined and incorporated in the GSM SMS standards.
