Is the Federal government wants to truly go mobile, recommend eliminating all landline phones and replacing them with either employee-owned or government smartphones. This will not only save money, but make life easier for all Feds.
Also, let's implement secure wireless systems to replace the old ethernet wired systems. This will allow more employees to work in less space, promote office-sharing, and provide true mobility for employees. This will also promote continuity of operations if Feds can securely access systems using any wifi hotspot.
