A mobile hotspot device may be used to interface one or more host computing devices with a wireless wide area network. The mobile hotspot device is powered by a high-capacity lithium ion (Li-Ion) cylindrical battery pack(s) and has a small, pen-like form factor. Use of the Li-Ion cylindrical battery pack(s) improves mobile hotspot device talk time over prismatic battery cell technology, as well as avoids premature device/modem shutdown experienced when a prismatic battery cell is proximate to a printed circuit assembly of the mobile hotspot device. Additionally still, Li-Ion cylindrical battery pack(s) avoid negatively impacting volume capacity of the mobile hotspot device. Further still, use of the Li-Ion cylindrical battery pack(s) allows for unique, interactive information display, as well as evolutionary mobile hotspot device design and form factors.

AIN services include multiple SCP pairs, which can be expanded to meet increased demand. The expansion can occur without cessation in services by migrating records between SCP pairs while maintaining redundancy between the pairs. A centralized GTT maintains the GTTs distributed between multiple subsystems in the AIN system. Synchronization between mate SCPs within a pair occurs at high speed as the subscriber database is split into multiple files, each file having a separate synchronization process.

Disclosed are embodiments of materials for microstrip and substrate integrated waveguide circulators/isolators which can be integrated with a substrate. This composite structure can serve as a platform for other components, allowing for improved miniaturization of components. In particular, a sintering aid can be used to improve the fit between a ferrite material and a dielectric material, improving performance.

Disclosed herein are embodiments of low temperature co-fireable dielectric materials which can be used in conjunction with high dielectric materials to form composite structures, in particular for isolators and circulators for radiofrequency components. Embodiments of the low temperature co-fireable dielectric materials can be scheelite or garnet structures, for example, bismuth vanadate. Adhesives and/or glue is not necessary for the formation of the isolators and circulators.

Disclosed herein are embodiments of low temperature co-fireable barium tungstate materials which can be used in combination with high dielectric materials, such as nickel zinc ferrite, to form composite structures, in particular for isolators and circulators for radiofrequency components. Embodiments of the material can include flux, such as bismuth vanadate, to reduce co-firing temperatures.
