Detect Cell-ID's nearby create a fixed connection towards that cell-ID


#1

Hi Peplink,

Would it be possible to get a feature that will enable us to see nearby CELL-ID’s on LTE.
And then to be able to do a selection which LTE CELL-ID the LTE modem should use.

This would be a great feature for static locations like disaster area’s or festivals. We could then force the PEPWAVE to connect to different cellulair towers. This would allow us to turn away from crowded towers. Also this would give us a chance to bond while using the same provider. Without bandwidth getting cut into half.

This would be an awesome feature to have for sure but I’m almost positive its just not possible. This is because the decision on which tower to connect to is made by the embedded cellular module itself and we can’t control or configure this. The only thing we can extract is the current CELL-ID that its connected to.

You could try and play around with locking to specific bands though.

Thanks!

Hi Tim,

Thnx for you fast reply. locking in to specific bands will indeed work. problem only is this will not work when its a LTE-A signal.

Think best possible solution we then have is using directional antenna’s and targeting other cellulair towers.

Would it then be possible that the peplink will have a feature that will ignore LTE signals when the signal strenght is to low?
Like some fixed vallue we can set for DBI strenght ect. when it falls below that it will ignore that CELL-ID tower.

This is a function of the cel systems and in our experience works pretty well. One thing you can do, however, if to use a directional (e.g., yagi) antenna and point it at the cel site you prefer. If you do that the RSSI seen by that site will likely be sufficiently great that the system is unlikely to want to make a hand-off to an adjacent cell. Even if the site would “like” to move you to another side because of capacity issues, it may not do so if the RSSI seen by a neighboring site is sufficiently low. The system will do all it can to guard against throwing your connection into the “bit bucket” – so you “stay” on the site of your choice.
We’ve done this numerous times and found the fade margin increases greatly and the momentary “drops” during hand-offs occur much less frequently.
