Mission: To be a trusted and preferred provider of jamming solutions for the toughest of environments.
B4 Limits Sp. z o.o., (“B4L”) located in Bialystok, Poland, possess over 10 years of jamming experience in the field of radio frequency jamming culminating in the introduction of the fully Polish made and designed Defender line of Wideband jamming products in 2024. The experience gained in jammer development for our external partners through the years, starting in 2015, allowed our team of highly qualified, PhD level engineers access to various jamming systems and platforms used by NATO allies, as well as, other recognizable special forces and VIP’s. As a result of this experience and growing interest in UAV jamming the company made a decision in 2021 to begin development of its own products in the form of Defender line of products predominantly dedicated to UAV, prison and telecommunications jamming.
PhD Led Team
10 years of core group development in exclusively jamming related projects. Vast knowledge of different systems
Experience
10 years of experience leading to delivery of projects to NATO based clients and those around the world (as a prime contractor)
Honesty
We will not develop solutions, such as jamming guns, because we think that such solutions have a low probability of success. It needed to be said. :)
Our Story
B4L was established on June 12, 2019 in Bialystok. The team consists of over 30 engineers, 15 of whom actively contribute to the creation and development of Defender brand jammers. B4L foundation of jamming development is deeply grounded in countless hours of hands on field testing supplemented by extensive lab research and development. As a result and because of this experience B4L is also a preferred development partner in the RF jamming space to a number of well known external companies, located in the EU, Switzerland and Middle East. Years of experience and collaboration with renowned research institutions and the national industry have created the competencies necessary to transform the "Polish scientific thought" of the national engineering staff into a representative product called the “Defender Wideband Jammer WB6500”.
