1  VSAT technology and installation / iDirect Forum: hubs and terminals / C Band and 3G/4G/P2P Inteference
 on: Today at 1:06pm 
Started by Rav | Post by Rav  
Hi guys. I have few queries about the C Band operations at 6GHz and 4GHz - Up and Down. The queries is as follows and will really appreciate if I can be helped with the following.

1. Is the C Band at 6GHz and 4GHz totally immune to rain fade or there is chances that during rain we can get the CRC8 and CRC32 errors on the iMonitor.

2. We have 3G/4G at 1.8GHz, 1.9GHz and 2.1GHz transmission at about 5 Meters from the Hub Station. Can the CRC8 and CRC32 errors be caused by the 3G/4G at the satellite hub. Our assumption is that because the frequencies are far apart, it would not cause interference. We used the Spectrum Analyzer but could not get any other transmission in the 3GHz to the 7GHz range.

3. Can a P2P Microwave at 18GHz cause the interference on the C Band Tx at 6GHz and Rx at 4GHz. The P2P Microwave is again at about 5 Meters from the Satellite Hub.

Regards

Rav

Hello,

I am trying to find a Tooway reseller/dealer in Europe that can provide me with a system that I can use in France. I prefer not to deal with the big companies. Does anyone have a recommendation or can assist?

Thanks! Wink

Would a Netgear Orbi wifi system work with the Satellite connection.

A basic mobile phone or a smart phone normally does phone calls and text messaging via a signal from a mobile phone mast network.  It needs an account with a network provider, a mobile phone number and SIM card. Frequencies and technologies are called 2G, 3G and 4G.

A smart phone may connect to the internet (for web browsing and emails) via either mobile phone mast networks of via a WiFi access point.  WiFi connection will be less costly than the mobile phone mast networks and thus ideal for software updates, video downloads etc. It is also good for Skype and similar internet based services.

If a smart phone has no SIM, it will still work on the internet via WiFi (for web browsing and emails).

The good news is that some mobile networks, such as EE, offer, as an extra service, phone and text via WiFi, called "WiFi Calling". This may only work in the UK.  Ask your mobile network provider.

Search "WiFi Calling" on Google.

If anyone can correct or elaborate on this please add your comments below.

Best regards, Eric

I was finally able to complete and activate my Tooway system, the reason of my problems was a faulty modem and when I got the replacement I connected with no more problems. Now I find out it is not possible to send and receive calls and texts using my smart phone although I can connect computers wireless using a Linksey E1200 router. I thought I would check on this.
