  1. 1. Path to  The 4G battle is on and operators are racing to secure the largest 4G footprint in the fastest pos- DiaMonD SponSor: sible time frame. The highest profile 4G players are 4G most likely Clearwire (and its wholesale partners), which have deployed more than 100 mobile WiMAX markets and Verizon Wireless, which commercially launched 38 LTE markets as of year-end 2010. But the 4G race is just getting started and first-to- market doesn’t necessarily equate to 4G leadership. Tier 2 operator MetroPCS is carving out a 4G niche with a handful of LTE market deployments and an platinuM SponSorS: interesting business model. Tier 1 operator AT&T is aggressively moving ahead with HSPA+ and plan- ning for a mid-2011 LTE deployment. T-Mobile USA is painting its HSPA+ network as 4G because it offers 4G-like speeds. And finally, new entrant LightSquared is promising to stir up the pot with its wholesale LTE network, which it plans to start deploying in 2011. Thus, 4G is no longer a possibility but a reality. But it also is becoming a source of confusion for consum- ers as they try to figure out why they should purchase this new fangled service. Some experts say that the operators aren’t helping the consumer by using 4G to describe their networks Is It tIme for a when they should be spending their marketing dollars to differentiate their services from the competition. According to a Yankee Group study released late 4G reality last year, aggressive marketing for 4G services and devices has only served to confuse consumers. In fact, nearly three-fourths of users in Yankee Group’s 2010 Anywhere Consumer study said that they do check? not know or understand what 4G is. And even more surprising, after years of marketing efforts, more than 50 percent of consumers still don’t know what 3G is. So perhaps the real solution for operators is to stop using industry terms like 3G and 4G as marketing messages to consumers and instead come up with marketing messages that really resonate.
