Finally, the Defence opposes all five documents containing cell site information in Annex B (‘Part II. Documents containing cell site data’).20 The Prosecution has made no showing of reliability beyond a tendered (but not admitted) witness statement, i.e. that of P-2687.21 The witness does not validate the tendered cell site documents, nor explain the critical details needed to decipher the reliability of individual cell sites. This is necessary to test the Prosecution’s case that a phone’s location may be derived from cell site activations. First, the range of cell coverage (the predicted geographic area within which a phone is most likely to connect to a cell) has not been established with sufficient specificity, and is very much a live issue: contrary to the Prosecution’s position that “the cell radius of Orange cell sites in BANGUI was limited to 4 kilometers,” 22 ORANGE’s own data indicates that phones may activate sites 19 kilometers apart. 23 In addition, cell site activations are subject to a myriad of factors including the load capacity and switch rates of individual sites, if and how often a company tune cell radio frequencies, the topography and interference of other objects, if a company measures the site location, and what steps a company takes to ensure that damage does not impact propagation.
