I have AT&T Uverse and I’m mostly happy with the service they provide. One of the issues that I’ve struggled with is their internet service. You are locked into using their router / gateway, as the one device provides the connections to TV, phone, and internet (both wired and wireless).
I have a desktop computer in one location that really doesn’t get the best wifi connection. I also don’t have a hardwired Cat-5 cable there either. The wireless generally works on that computer, but I noticed recently that the connection has been really slow. I started to wonder if it was my baby monitor video camera interfering.
Looking online, it seems like other people have reported the same problem. It is interesting that the video monitor uses the same 2.4ghz spectrum as most wifi internet, but it uses it in a different way. Wifi internet uses a specific channel within the 2.4 ghz spectrum and you can set the channel used on the router to try to reduce interference from other wireless internet routers. The Infant Optics video camera, though, uses a different technology called Frequency Hopping Spread Spectrum which constantly changes the channel being used by the camera. As a result, it basically interferes with all the channels, regardless of what you set your internet router to use.
It turns out there isn’t a whole lot you can do, other than trying to keep the video camera and the receiver as far from the wireless internet devices.
But there are two additional options. The newest wireless routers now are “dual band” meaning they can broadcast in both 2.4 Ghz and 5 Ghz. You also need to have a device that can accept the 5 Ghz signals, though. Most older wifi cards and laptops can not receive on the 5 Ghz band. However, it would be fairly easy to get a 5 Ghz card for my desktop computer. As I mentioned above, with Uverse, you are stuck with the router they give you. But, you can actually use a different wireless router behind the Uverse router with some setting changes. The other option is something called a powerline adapter. Powerline adapaters allow you to use your home’s electrical wiring to create a hard-wired connection between the router and the computer. There are pro’s and con’s to each of these options that I will probably write about soon, because these are the options I had to mull over.
Before I jumped to one of those options, which would involve shelling out additional money, and still may not work, I decided to email Infant Optics and see if they had any solutions. Here’s what they sent:
Thanks for your e-mail regarding to the WIFI problem with our DXR-5.
Our system operates with FHSS (Frequency-Hopping Spread Spectrum) technology. It is an industrial standard for radio-frequency (RF) devices. The idea of this standard is to avoid any RF device to occupy a fixed communication channel so other devices will not able to share the same frequency band (i.e. 2400MHz to 2483MHz). So, we are sorry that we cannot fix the communication channel at any specified frequency, as it is required by government regulations.
However, nowadays, all 2.4GHz router are still using an old and fixed communication channel to achieve a steady performance and huge transfer rate. The bandwidth, which they occupy, is also huge (15Mhz per channel for WIFI, and 3MHz for our devices). Considering that we are sharing the same 2.4GHz frequency with the WIFI device, it is difficult to totally eliminate the possible conflict between 2 devices.
Our first suggestion is trying to use the channel 1 or channel 15 (the last channel) of your router. The conflict between WIFI and our devices will be less at both ends. Also, it will have less overlapping of frequency from other WIFI device (says the WIFI router at your neighbor)
Our other suggestion is try to place your RF devices (including your router, PC/smart phones, our camera and monitor unit ) at proper location. Putting any 2 device too close together will definitely result in higher potential risk of conflict. Placing them further away from each other will help to decrease conflict.
I hope the above arrangement will help the situation. For any further questions, please feel free to contact us. Your satisfaction is our utmost priority and we will be happy to guide you through a product return if needed.
