While no further CRJ100 or CRJ200 jet liners have been constructed since 2006, over the years since then, various technologies and innovations have been retrofitted onto examples of the type, which have largely remained in commercial service. Some of the operators of the larger versions, such as the CRJ700, have undertaken work to install Wi-Fi capabilities on board the type; however, to date, no airlines operating the CRJ200/100 had chosen to implement an onboard Wi-Fi compatibility.[39][page needed]
