A while ago, Excentis launched a standalone LTE Immunity certification test program. The objective of this program is to ensure that cable services are not disturbed by electromagnetic fields generated by wireless equipment (currently LTE devices) using the 790-862 MHz sub-band of the digital dividend frequencies.

Excentis now introduces a small but important change: a product (CM, EMTA or STB) can from now on be submitted for LTE Immunity certification against a specific level of E-field. By default this is 5 V/m, but a submitting vendor can alternatively request for the product to be tested with a different E-field. Allowed E-field values are 3, 4, 5, 6, 7, 8, 9 or 10 V/m.
This gives full flexibility to the vendor so that it can build its products against the specific immunity requirements of its customer(s).
The Certification letter and the listing of Certified products on the website will also mention the E-field for which the Certification applies.
