"Mobile operators are currently deploying fifth-generation networks (5G) which will underpin the ultra-connected world and Internet of Things."
Joint Operators Technical Specifications
The JOTS forum publishes technical specifications to enable mobile operators and their partners to deploy high-quality shared wireless solutions for the benefit of their customers.
Joint Operators Technical Specification Forum
The aim of the JOTS forum is to specify the performance, coverage and reliability of wireless systems that are shared by mobile operators. The JOTS forum specifications should be referenced by equipment providers and installers when they deploy shared radio solutions for the benefit of mobile operators and their customers.
The UK JOTS forum was founded in 1999. Out of the close co-operation between the mobile network operators (then known as Cellnet, one2one, Orange and Vodafone), the first GSM joint technical requirement document for third-party indoor coverage solutions was issued on 5th May 1999.
Over the past 20+ years, this original JOTS document has evolved to include GSM, UMTS, LTE and NR and stands as a reference and a framework covering the design and test requirements (non commercial) of indoor Distributed Antenna Systems (DAS).
JOTS Distributed Antenna System specification
The JOTS Distributed Antenna System (DAS) specification sets out all of the technical requirements for all types of third-party in-building solutions based on Distributed Antenna System solutions.
JOTS Neutral Host In-Building specification
The JOTS Neutral Host In-Building (NHIB) specification sets out all of the technical requirements for shared in-building solutions using small-cell base stations.
