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.

A cell tower configured all mobile phones to switch to Band 3 when necessary. This part of Band 3 can be linked to a part of Tigo 2G that carried traffic (AirtelTigo relies on Airtel's Band 3 spectrum instead). It is small and doesn't do much by itself. Theoretical download speeds are up to 37Mbps or 50Mbps or 100Mbps, depending what the tower has and what the mobile phone has. Upload speeds are up to ~19Mbps or lower. If a tower is upgraded with Carrier Aggregation(CA_3A-7A-20A), 4x4 MIMO (2/3), and 256QAM (3/3), mobile phones that also have all of these will get download speeds of up to 650Mbps. However, the theoretical speed is only between a tower and a mobile phone, a speed cap such as 200Mbps may be used (but it's not necessarily enforced), or the backhaul may be insufficient. 1Mbps = 125 KB/s. Band 3 is sometimes called DCS, 1800, or L18 (if it's 4G). Here's the message that configures mobile phones to switch to Band 3 when necessary. These take effect after ...

SOLVED The phone chose another network that has signal. This other network informed the phone that all services are not allowed. After receiving this information, the phone will consider the 4G-capable SIM invalid until the 4G-capable SIM is removed or the phone is restarted somehow.  See subclause 5.5.1.2.5 of https://www.etsi.org/deliver/etsi_ts/124300_124399/124301/12.06.00_60/ts_124301v120600p.pdf . A SIM replacement is not required. Simply re-insert the SIM or restart the phone somehow. Colors in the image above were changed, because naming the network that sends "8" is not within the scope. You may be affected if you are located in or near Accra or Tema, and are using one of these networks: • MTN Ghana; • Vodafone Ghana; • Removed, because it was solved. AirtelTigo and Glo might not issue USIMs (4G-capable SIMs), subject to change. Until this issue is solved, you can prevent this issue from occuring by preventing the phone from using (removed, because it is solved) : • ...

(Video) A partial shutdown of 2G DCS/1800MHz/Band 3 begins at 0:05 (12 am). (Video) It is fully returned at 6:05 (6am). Comparing DCS to PGSM/900MHz/Band 8, •More of the signal strength is blocked when it passes through obstacles (including air). •It is better at fitting through gaps in obstacles, such as between trees. •The mobile's maximum transmit power is halved. •It is less likely to overlap and conflict with other towers or itself. •Additionally, the signal is 25%* less likely to overlap and conflict with another tower. •It is separate, calls made on DCS do not use resources of PGSM. At night, due to low usage, the PGSM should be adequate for calls(and low speed data, though 62.5%* of 2G PGSM might be used for 3G in some cases), and 3G/4G should be adequate for data; so DCS won't be of much benefit. What is this? The signal strength of nearby towers. What's an ARFCN? Similar to the MHz on a FM radio. The ones here carry phone settings to all ...
