them all. The important feature in ranking these data and other services is not their general QoS, not their bit error rate (BER), but specifically their delay. The other factors are taken into account in their E/No calculations in the air interface. When we are done, each MSC will have a packet pipe traffic engineered with enough capacity for all the levels of data service delay. 37.2.3 Private wireless networks We have discussed public wireless voice, data, and other services, but we expect third- generation (3G) systems to develop a growing market for private networks. Part of this demand is simply a result of the enormous number of subscribers we expect 3G CDMA to be serving, whereas part of this demand is a result of the flexibility of 3G CDMA, es- pecially in the data services area. Private network customers will arrange their own transport for voice or data. When customers decide to use a wireless telephone system for their own private voice networks, they will get mobile telephones for their users, and they typically will get their own transport from the MSC to their own telephone network. They may lease their facilities from the PSTN, but those facilities are not public telephone trunks. These services would generally be within a LATA and therefore would be available as metropolitan area network (MAN) services from the local access provider.

MSC Transport Planning MSC Transport Planning Private wireless voice networks have been around for a while, but private wireless data networks are as new as wireless data service. Private data network customers will equip their users with data terminals of whatever sort suits their needs. Perhaps their data terminals will be wireless laptops, but they may be devices designed by the cus- tomer, custom tailored to a specific task. The private data cu
