The proposer will determine if Wi-Fi or cellular network is the best network for the study area. IPS complies. IPS provides meters that utilize digital cellular technology, and can provide meters on either the GSM (T-Mobile) or CDMA (Verizon) network. IPS was the first single-space meter vendor to have meters certified on both networks. Our meters provide a pre-integrated and certified wireless service that has proven to be both extremely cost effective and exceptionally reliable (99%+ uptime). IPS integrates the wireless module directly into our meter. We do not use an air-card due to the fact that it is not application- specific and results in poor power performance and slower connectivity. Switching from one carrier to the other only requires a communications board replacement. Due to several negative factors, IPS does not currently provide a WiFi or mesh communication system, primarily due to the impact on meter performance, reliability and costs. While IPS is very familiar with this technology, we continually find that City coverage and reliability of WiFi networks are inconsistent and unable to achieve the 99%+ meter communications threshold that we are able to supply with our current cellular based meter. Additionally, private systems are very costly to operate and maintain. More information is provided below. h. MSMs and/or smart meters shall accept coins in the following denominations: One-dollar coin, Half- dollar, Quarters, Dimes and Nickels. The MSMs shall have ability to filter all coins and only allow official US currency. REV: 05-05-16 JS Page 26 of 177 ATTY/AGR.201 6.094/IPS Group
