Selela
In Selela 2G networks from various operators are present, though none of them has a 3G coverage at the market place, the dispensary or the school. The main reason is that the 3G towers are too far away, in the case of Tigo the distance is more than 20 km from Selela to the Tigo tower on the hill-side close to Mbo wa Mtu.
As shown in Figure 1, the tower is on a mountain ridge north of Mbo wa Mtu. We have performed network measures, with good reach up to 7-9 km, indicated by the two green dots in the right area of Figure 1. Our mobile network measures, performed both at Selela and Mbaash, showed a received signal level of -106 dBm, which is below the lxxxxxmore than 20 km away,
Current installation
Currently the market place is connected, based on a 3 m pole connected to an existing pole on the roof, reaching up to about 6 m over ground. The mobile network connects to the 3G Tigo tower through directive antenna more than 20 km away. The connectivity is UMTS 900 MHz connection.
- Equipment includes:
- (1) Internet Link
- (1) LNCC
- (1) Raspberry Pi
See list of equipment at Selela_Market_(TZ)
Future extension
The potential extensions include a link to the school, and the link to the dispensary. However, we first need to clarify on how to attach the pole to the buildings.
