Cellular service : Number portability, 3G, WAP

Number portability
In the 1990s, the FCC mandated that the wireless phone industry must implement a number portability system. Historically speaking, cellular phone numbers have not been portable. If a user changes from Bell Atlantic Mobile to Sprint PCS, she has to get a new phone number. The old number is recycled by Bell Atlantic Mobile and Sprint PCS assigns the user a new number.

This process is so frustrating that most customers simply stay with the current carrier, rather than experience the “pain of change” to a new carrier. Getting a new phone number may require a business user to print new business cards and new letterhead, and the user must inform his clients of the new number. Few people are willing to go through this headache just to save a few dollars each month.

Third-generation technology
Telecom suppliers worry about the capacity of their networks. If the network is maxed out, they cannot enroll new customers, and existing customers switch to different carriers. New technologies are implemented to increase network capacity and allow carriers to offer more sophisticated services to their customers. The next significant wireless telecommunications technology is referred to as “the third generation.”

Three 3G technologies have been developed, but none has yet been deployed. The three technologies are WCDMA, CDMA2000, and TD-SCDMA, developed by Americans, Europeans, and Chinese, respectively. Governments, telecom manufacturers, carriers, and other power brokers are still deciding which technology to deploy. 3G is often in the news because of the high-level negotiations deciding the future of the wireless industry, but until it is deployed, 3G is not very relevant for the end user.

WAP
WAP allows mobile telephone users to send and receive electronic data. WAP has been heavily marketed by carriers, but the service has had a rocky start. The service had many technical glitches, and the technology’s early adopters lost their enthusiasm. WAP’s biggest drawback is that it is not user friendly. Data input is inconvenient, and most customers cannot tolerate the tiny display screen.
