Lattelecom launches WiMax trials

Lattelecom has launched trials of WiMax wireless internet in the Riga suburb of Marupe and at least one other place, this blog has learned.
This is intriguing for a number of reasons. First, it solves the problem of broadband access beyond the reach of Lattelecom's DSL network. Second, WiMax is a possible mobile solution for Lattelecom, though not earlier than 2008 or 2009, since mobile WiMax really doesn't work anywhere, yet, except some experiments in Korea, where it is called WiPro.
For fixed and nomadic clients, WiMax can, essentially, be a platform for all possible services -broadband, voice, VPNs, software as a service, etc., the way DSL is sort of becoming the universal platform on the wireline network.

Any idea how to participate in those trials? Do they have PCMCIA wimax cards for laptops?

Hi Solynshok,
Don't know. Been trying to get in touch with the main man on the project, but his phone is off the grid.

Interesting question. Many-many people are working on WiMAX downlink solution such as PC-cards and so on. Some are available and will already or very soon be comercial. The WiBro tests (= basically an early version of WiMAX 2005, even called IEEE 802-16e) earlier this year for selected people of the WiMAX forum showed a very clear shortcoming: battery times for WiMAX modems and cards litterarly sucked. What about surfing times of less than one hour with a pavement stone battery size? Or what about your laptop or I-book that normally runs about 3 hours on a full charge and now shuts down after less than 45 minutes of surfing the web or talking through Skype?
The modulation scheme choosen for WiMAX is similar for up- and downlink. This solution gives high transfer rates in return for loads of energy. I'll just say Long Term Evolution (3G LTE) and/or IEEE 802-16m. Keep an eye on this! As it appears WiBro also suffers of annoying latencies when the network load is high. This is technically understandable, but hardly acceptable for gamers and Skypers.
Once again: LTE.
