Vodafone Ghana 'Band 28'

If a phone supports Band 28 but doesn't support Band 20, Vodafone Ghana may still be detected. This is because the downlink (site to phone) frequencies for the center part of its Band 20 are a part of Band 28. There's a difference in the frequencies phones transmit around. On Band 20, phones transmit around 798.5 + 41 = 839.5 On Band 28, phones transmit around 798.5 - 55 = 743.5 Logs: ProtocolEvent.

MTN Ghana Band 3 4G activated

It may have a capacity of 75Mbps / 100Mbps / 200Mbps, because its bandwidth is 10MHz. The capacity depends on the technology available between phones and the tower. Normally, this frequency is used for MTN's 2G, not 4G. Yet, the frequency was used for 4G at least once and in at least one area. A partial refarm. It can be seen that Band 3 4G is in use with the *#0011# service menu on a Samsung phone. Band 3 can also be added for carrier aggregation. In the screenshot, Band 3 and Band 20 are used together. Unfortunately, other metrics in the screenshot don't look good, but please do not guess that it's a problem with how the network is set up. Other towers signal the availability of 4G Band 3. The phone's ability to reselect is available after 5 seconds of sending or receiving no data, handovers (network-assisted 'reselections') are performed otherwise.
