Huawei, the fast-growing Chinese network equipment maker, has developed software that lets operators screen out 75 percent of the digital pulses, or ''heartbeats,'' that are continually sent by smartphones to maintain a contact with a base station. The developers found that even when the frequency of the pulses was reduced, the phone would remain in meaningful contact with the network, while allowing operators to carry more calls and data.
