Schools Liaison Officers

Charles Hendry: To ask the Secretary of State for the Home Department which police authorities have appointed schools liaison officers. [153060]

Ms Blears: This information is not held centrally. The appointment of schools liaison officers is an operational matter, and is a decision for Chief Officers.

Tetra Masts

Mr. Gibb: To ask the Secretary of State for the Home Department whether any applications for planning permission for Tetra masts have described the modulation characteristics as pulsed. [153016]

Ms Blears [holding answer 5 February 2004]: The Home Office is not directly involved in the mast planning process. Planning applications for Tetra masts for the new police radio system, Airwave, are a matter for the network provider, Airwave mmO2.

The modulation scheme used by Tetra is known as Differential Quaternary Phase Shift Keying (DQPSK).
