Same here- I don't know much about Telkodemonopolies' network topology, and I agree it could be a problem in cases where Vodacom & MTN share the same physical base-station site & mast as Telkodemonopolies likely forces them to share the same physical backhaul link.I agree they definitely need to own their own backhaul links, I'm just wondering how Telkom's network is set up, if it'd be possible to buy it piece by piece like that or if its too integrated and they'd have to rather run their own fibre to replace Telkom's network entirely. If there's one piece of fibre running from each tower to an exchange then as you said they'd just have to run their own fibre to each exchange and interconnect from there, but if these physical lines are effectively shared by one or more cell networks and various other companies I'm not sure how possible that'd be, but admittedly I know nothing about Telkom's network topology, I'm just speculating.
I just think that too many assumptions are being made about what MTN wants out of Telkodemonopolies - specifically that MTN wants more than bits & pieces of network infrastructure - IMO MTN is not interested in buying up most of Telkodemonopolies, instead I think that MTN has a list of things that it wants to buy from Telkodemonopolies to give MTN a competitive edge in the short-term & going forward. Also, the dividends associated with Telkodemonopolies' sale of its 50% of Vodacom are expected by shareholders - there will be hell to pay if Telkodemonopolies does not sell off at least part of its 50% of Vodacom - I'm sure Poison Ivy et al will insist that the full 50% gets sold ASAP.
