Telecomm is recovering~ but not wireless

It seems like wireline market is much better than wireless because of new need on 10-, 40- and 100 Gbit/s Ethernet networks in many areas.

Also, Optical Transport Network(OTN) technology is pretty hot topic recently. It is very useful in communicatio networks for packets processing and optical transport.
"Starting in 2010, Verizon plans to deploy for its Fios network only OTN systems that support both optical transport and packet processing". And a lot of companies are working on the projects related to OTN, like HuaWei.

Does it mean we need to switch the research area to optical networks?
