We had a customer request that we create a solution to provide wireless network coverage in a remote greenhouse. Inside the greenhouse, the temperature and humidity could exceed the specifications for the indoor MR access points. The greenhouse was approximately 30 feet by 30 feet, so one AP should cover it with no problems. We settled on using an MR70 AP. It is outdoor rated and WiFi5 was more than sufficient for the wireless clients that will be used in the greenhouse. The greenhouse is a little bit lower than the surrounding terrain, and even though the cellular coverage was not stellar, it was present. So we chose the MG41 because of it's outdoor rating and the fact that it can aggregate multiple LTE frequencies together. Since the cell signal was sufficient inside the greenhouse, we chose to mount the network equipment inside it, even though most of it is outdoor rated. We first chose to use two PoE injectors back to back to power the AP and the cellular gateway, but decided later that they might not be able to survive the environmental conditions inside the greenhouse for an extended period of time. We chose to replace them with an 8 port, unmanaged PoE+ industrial switch. The switch should be able to tolerate the environmental conditions for an extended period of time and it also provides more wired ethernet connections in case the customer wants to hardwire any network devices. The MG41 is bonding two and sometimes three LTE frequencies together, and even though the cellular signal strength oscillates between poor, Ok and Good, the network speed tests show speeds of around 20 megabits up and down consistently. This is more than adequate for the needs of the customer. We also installed a cheap APC UPS to protect the network equipment. It may not be able to survive the environmental conditions for an extended period of time, but it was only $65 and can easily be replaced. The customer plans to use wireless sensors to monitor the soil moisture and temperature for the plants in the greenhouse and they also need to monitor the water level and temperature of an aquaculture tank with about 75 crawdads and muscles in it. Once again, Meraki equipment makes this solution viable, simple and resilient.   Greenhouse exterior view Greenhouse   Plants in the Greenhouse plants   MG41 and MR70 MG41 and MR70   Side view of the MG41 and MR70 side view of MG41 and MR70   Crawdads and Muscles in the aquaculture tank Crawdads and Muscles ...

I installed some of the new MV52 cameras over the last couple of days and they work great. They really do need more than 15.4 watts of PoE power. And it's not even cold enough yet to run their heaters. We may get to see that later this week here in Oklahoma.   Camera power draw ... View more

One of our customers has an MT10, along with an MT12 and MT20, monitoring their Data Center. The MT10 started alerting on December 7th that the temperature in the Data Center had reached 75F, when the normal average temperature should be around 70F. After alerting their building maintenance team, their technician found a blown fuse on the compressor for the system. The fuse was likely blown due to a brown out caused by a severe storm in the area on the night of December 6th. You can see when the HVAC system failed and when it was repaired on the picture below. Another MT10 just paid for itself very quickly.     MT10 ... View more
