Role purpose


Analyse detailed RF requirements across our radio network and propose detailed designs to support the rest of the VMO2 organisation. The role needs to interpret any new requirements driven by radio technology change and recommend changes that need to be implemented to enable the continued rollout of our future RF capability.


Key accountabilities/responsibilities 


• Drive clarity, provide technical leadership and guidance across the Telefonica estate in terms of RF best practise Radio Design.

• Single point of contact for all technical related Intermodulation issue escalations and resolution.

• To be creative and update, improve and facilitate national change on our current processes and aid the migration into our tooling for all RF related design changes.

• To host training workshops for internal / external bodies relating to best practise RF guidance and mandatory requirements.

• To work with all key stake holders to implement RF design into our tooling & wider teams/end users.


Essential Skills

•    A full in-depth knowledge and understanding of RF Design

•    Full 2G, 3G, 4G & 5G radio access design and implementation knowledge, particularly dependencies between Radio Access Technologies such as CAA, CSFB and Remote Anchorin
•    Previous experience working with radio & antenna vendors to drive through a common approach to site assessments and knowledge sharing.

•    Experience working to create succinct processes for multi-disciplined business areas driving harmonisation.

•    Previous experience providing RF health and safety training to all levels of engineering and management.

•    To support global antenna RFI’s and work closely with VMO2’s technical partners in Spain and Germany, along with Telefonica’s Global and purchasing partners (TGS) to collate all information and material for ongoing annual antenna RFI’s.  This includes but is not limited to – technical evaluation of antennas from suppliers and UK purchasing agreements with the intent to ensure a successful RFI outcome.
•    To support the UK RF component and ancillary RFI’s.  To provide a technical breakdown and evaluation of RF components including Combiners and MHA’s from suppliers, then to work closely with UK purchasing to ensure a successful RFI outcome.
•    To produce all technical documentation for approved antennas in terms of application and utilisation; including but not limited to – technical guidance, good practice guidance and fault rectification documentation for use by regional build teams, build contractors and designers.
•    To work closely with passive antenna and RF component suppliers on a continuous basis to ensure long term development and antenna improvements.
•    To test and evaluate products and new incentives. This currently involves working with Global companies such as Commscope, Huawei, Rosenberger, Ericsson, Nokia and Radio Design to establish best practice and application of supported products and new incentives.
•    To work closely with active antenna suppliers on a continuous basis to ensure long term development and antenna improvements and to test and evaluate new products and incentives. This involves working with Global companies such as Ericsson and Nokia on M-MiMo and Active / Passive antenna products.
•    To work and support internal teams within VMO2 by ensuring all new antenna’s have active and valid Quantum codes in place for inventory purposes.

This involves working with a detailed understanding what developments are required for future technology deployments and working with suppliers on suitable products to bring new solutions into the network for BAU deployment. 
•    To own end to end site interference and noise mitigation caused in the RAN by mixing multiband frequencies and technologies. Specifically looking at how sites can be designed and improved to ensure networks do not generate PIM. To ensure that the combining of utilised bands is done in such a way that PIM is in all instances designed out as much as practicable.   
•    A working knowledge of PIM, its generation and mitigation as well as understanding how PIM is generated and designed out is essential.  Understanding how to rectify sites that exhibit poor PIM performance as well as how site design can reduce IM in the network are fundamentally important to this role.
•    The role involves working closely with the National Design and Build teams on both BAU, and strategic planning of future design enquiries.  This includes responding to ad-hoc requests for bespoke / hidden solutions.
•    To be a single point of contact for the regional antenna delivery leads and to assist with all antenna enquires, future scoping and possible limitations moving forward.
