Wireless for Law Enforcement & Homeland Security Training

Introduction:

Wireless for Law Enforcement & Homeland Security Training Course Hands-on

In this four-to-five day Wireless for Law Enforcement & Homeland Security Training Course Hands-on course, you will undertake a non-technical yet fairly deep review of wireless technologies from the perspective of law enforcement. The optional fifth day adds a day-long case study of the particular technology of interest to the audience.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
