Microwave, WiMAX or Fiber IP?
The potential savings are substantial if a TV Station can eliminate (or greatly reduce)
the use of ENG Vans with link-to-studio microwave, perhaps replacing the majority
of ENG Vans with mini-vans or even station wagons.
Fig. 15. In less than 5 years, HD ENG backhaul may be accomplished
through a combination of WiMAX and Fiber IP within a metropolitan
area. Frequent ENG program origination points may have pre-wired
Fiber IP network connections while other points are in proximity to
WiMAX service. The traditional large ENG Van, with costly microwave
electronics, dish antennas and telescopic masts, may only be used for
rural reporting where WiMAX and Fiber IP are not available.
Change is inevitable – Keep your options open.
