The market for wireless devices is high, however profits are down because the per unit cost is falling. Manufacturers are scrambling to find ways to prop up sales of thier products. One way seems to be the ‘ala carte’ method of a modular wireless network where the customer only buys what they need and can expand, rather than scaring them away with high cost of entry. The usual manufacturer/standards squabling seems to also be affecting the market. Proprietay extensions and control locks in customers to specific vendors. Hopefully the realize that working together might make the market grow more than fighting against the customer demands.
