Lattelekom has the biggest potential broadband customer base (a fair chunk of its 600 000 fixed network users) but is falling behind in the high-speed bells and whistles that some other providers can offer. Balticom, for instance, offers 10 Mbps in some Riga suburbs and a few downtown locations.
The biggest threat to Lattelekom is in the new/renovated housing market, where the inhabitants are likely to have the necessary discretionary income to buy high speed services and premium content (such as HDTV over the internet, when it become available). Here Latvenergo, the state owned energy utility and its subunit, Latvenergo Telecommunications, are putting in fiber to the home with speeds of up to 100 Mbps. While I am not sure just what you can do with 100 Mbps (show me the servers that can unload multiple streams of content at those speeds), Latvenergo has the advantage of putting in this service pretty much wherever new electricity connections are made. It has already run fiber to the residence in some multi-dwelling buildings and will soon be doing a single family home development of a number of homes.
My sources say Lattelekom has a plan to put up to 24 Mbps DSL in many Riga homes. In a major upgrade of its fiber optic network in most of Riga, the incumbent will install fiber to the curb units attached to mini-DSLAMs in local boxes that will deliver very fast DSL to an entire block of homes and businesses. This will involve replacing existing switchboxes with newer models that have back up and main power supplies, since the DSLAMs apparently need to be seperately powered. In other words, a bit of digging and installation.
Before that, you will probably see Lattelekom speeding up its existing DSL connections from the present 1 Mbps (pay LVL. 1.99 per month extra) to something like 10 Mbps just to keep up with the likes of Balticom and to at least match what Latvenergo will offer in its basic fiber to the home package.
