RE: If it didn't work for ensembleMaybe Ensemble didn't have all the pieces of the puzzle in the right place, Maybe their products were inferior compared to that of their competitors, maybe their sales department sucked, maybe management took a back seat thinking their financers would bail them out if they had financial difficulty, .... many many reasons it may not have worked for Ensemble but could work for Wilan.
Just because Ensemble had a component of broadband wireless products correct and at their finger tips, doesn't mean that they will be able to produce, market, and sell wireless products.
For example a company might invent the best drill motor ever seen to man... if they are in the business of selling drills but can't put together a descent drill then they will surely go out of business.
Also,
Heavyweight backing also does not always mean success... sons/daughters of a wealthy families do not always succeed.
