根据向该机构提交的文件，许多墨西哥边境附近运行800MHz LMR系统的美国许可证持有人正寻求延长FCC提出的30个月时间表，该计划要求2015年年中完成大规模的再贷款项目. 据舒尔曼罗杰斯律师事务所合伙人艾伦蒂尔斯表示，由于技术和政治原因，南部边境地区的再担保预计要比北部边境地区的难度大得多，这就是持牌人要求延期的原因. 只有美国与加拿大和墨西哥达成条约协议后，边境地区的再通货才可能开始。

据舒尔曼?罗杰斯律师事务所合伙人艾伦?蒂尔斯（Alan Tilles）表示，由于技术和政治原因，南部边境地区的再担保预计要比北部边境地区的难度大得多，这就是持牌人要求延期的原因
蒂尔斯接受《紧急通讯》采访时说：“这与（为美加边境的持牌人制定的）相同。”我们已经看到加拿大边境地区没有足够的时间，这里情况会更糟，因为回扣会更困难。……比加拿大复杂得多
“很明显，这是不现实的，为什么我们要这份文件中规定无法达到的期限？”
代表客户向联邦通信委员会提交的一份文件中，蒂尔斯要求欧盟委员会总共延长10个月——他说，考虑到目前的情况，延期应该被理解为“最低限度”
与此同时，圣地亚哥县也文件中称FCC时间表“乐观”，指出它与联邦国防用户共享站点，通常需要两年时间才能批准此类频谱更改，然后才能进行任何重新绑定工作。该县还表示，Sprint计划于明年关闭其iDEN网络，可能会对整个系统性能产生负面影响
“治安官指出，斯普林特宣布于2013年6月30日关闭其800兆赫iDEN语音和数据网络的时间，有可能对公共场所内800兆赫公共安全无线电系统的覆盖范围产生不利影响，并公共安全用户和斯普林特之间造成敌对局面，并建议联邦通信委员会（FCC）采取措施减轻这种可能性
2004年，联邦通信委员会（FCC）接到报告称，商用蜂窝信号（主要来自Sprint收购的Nextel）干扰公共安全LMR通信，批准了一项重新配置800兆赫频段的命令。再融资本应于2005年开始，2008年结束，但过去的8年里，由于种种原因，该项目一直被推迟
只有美国与加拿大和墨西哥达成条约协议后，边境地区的再通货才可能开始。与墨西哥的协议是今年夏天签署的
Numerous U.S. licensees operating 800 MHz LMR systems near the Mexican border are seeking extensions to the 30-month timeline proposed by the FCC that calls for the completion of the massive rebanding project in mid-2015, according to filings with the agency.
For technical and political reasons, rebanding along the southern border is expected to be much more difficult than it was along the northern border, which is why licensees are asking for extensions, according to Alan Tilles, who represents many affected licensees as a partner inthe law firm of Shulman Rogers.
"It's the same proposal [that was established for licensees on the U.S.-Canada border]," Tilles said during an interview with Urgent Communications. "We already saw that there wasn't enough time in the Canadian-border area, and it's going to be worse down here, because it's going to be a harder reband. … It's multitudes more complicated than Canada.
"It's very clear that it's unrealistic, so why are we putting unreachable deadlines in this document?"
In a filing with the FCC on behalf of clients, Tilles asked the commission for a total of 10 months in extensions — extensions that he said should be construed as a "minimum," given the circumstances.
Meanwhile, San Diego County also called the FCC timeline "optimistic" in its filing, noting that it shares sites with federal defense users, which typically take two years to approve such spectrum changes before any rebanding work can be done. The county also suggested that Sprint's shutdown of its iDEN networks — scheduled for next year — could have a negative impact on overall system performance.
"The sheriff notes that the timing of Sprint's announced shutdown of their 800 MHz iDEN voice and data network on June 30, 2013, has the potential to adversely impact the coverage of 800 MHz public safety radio systems inside public venues and create an adversarial situation between public safety users and Sprint, and recommends that the [FCC] take steps to mitigate this potential," the filing states.
In 2004, the FCC approved an order to reconfigure the 800 MHz band after receiving reports that commercial cellular signals — primarily from Nextel, which was bought by Sprint — were interfering with public-safety LMR communications. Rebanding was supposed to begin in 2005 and conclude in 2008, but the project has been delayed for numerous reasons during the past eight years.
Rebanding in border areas only could begin after the U.S. reached treaty agreements with Canada and Mexico. The deal with Mexico was signed this summer. |
