Tag Heuer Monaco V4 Watch

Ta-Heuer-Monaco-V4-Limited-Edition_3Tag Heuer Monaco V4 Watch – You’re looking at the world’s first watch with belt drives, linear mass and ball bearings.  We feel, however, that you could throw out those little stats and this watch would be just as sexy.  After it’s initial announcement in 2004, the Tag Heuer Monaco V4 Watch has officially been released to the public, with 150 units selling for just over $80,000 each. The hands inside the Monaco V4′s platinum case are driven by a set of five of the world’s smallest belt drives and ball bearings, an unique approach to driving such a calculated timepiece.  If you’re one of those lucky enough to afford this revolutionary piece of watch history, we’re jealous.

Motorola :: Backhaul or extend your network wirelessly.

High-performance, point-to-point radio solutions operate in many frequencies, providing reliable connectivity when and where you need it, even in the most challenging environments such as Motorola Bridges .

I think Motorola bridges are reliable after deploying one ,  result is awesome .

PTP 500 Series to deliver high-speed, robust wireless back haul. Connect buildings in a campus setting. Extend video surveillance beyond the wired infrastructure. Support bandwidth-intensive applications such as Voice-over-IP, tele medicine, IP gaming and multimedia. The PTP 500 bridges can deliver up to 99.999% availability in virtually any environment, including non-line-of-sight, long-distance line-of-sight, over water or open terrain, even through extreme weather conditions.

PTP 500 Series bridges come in Integrated and Connectorized models, both available in 5.4 and 5.8 GHz RF bands and operating at data rates up to 105 Mbps.

CellTrack software for Telecom engineers

CellTrack is a program to collect some phone information about the cell you are connected to - like the net monitor. For more information about GSM net search the web.

It helps me to find problem in telenor pakistan connection because my calls keep dropping , after complaining again and again and problem not resolved i take matters in my hands and try to find the problem .

Finally i find out that i am in dispute area and after specific signal strength my cell phone change cell while it changing cell my call drop ( Ping pong issue ).


Recommendation

It will be optimize that it should not switch cell until unless signal strength is less than 30 % or something .
 ( Not sure how they optimize , i don't think they know optimization at all , stupid telenor )

Kamailio top-notch SIP Server ( Former OpenSIR )

Combining its SIP core capabilities and extensible APIs, building VoIP and Unified Communication Platforms using Kamailio (K) is straightforward.



Some of the features that Kamailio offers:
  • Robust and Performant SIP (RFC3261) Server flavours
    • Registrar server
    • Location server
    • Proxy server
    • SIP Application server
    • Redirect server
  • Flexibility
    • small footprint – suitable for embedded devices – the binary file is small size, functionality can be stripped/added via modules
    • plug&play module interface – ability to add new extensions, without touching the core, therefore assuring a great stability of core components
    • modular architecture – core, internal libraries and module interface to extend the server’s functionality
    • impressive extension repository – overall 150 modules are included in the Kamailio source tree
  • SIP Routing Capabilities
    • stateless and transactional stateful SIP Proxy processing
    • serial and parallel forking
    • NAT traversal support for SIP and RTP traffic
    • load balancing with many distribution algorithms and failover support
    • flexible least cost routing
    • routing failover
    • replication for High Availability (HA)
  • Transport Layers
    • support for communication via UDP, TCP, TLS and SCTP
    • IPv4 and IPv6
    • transport layer gatewaying (IPv4 to IPv6, UDP to TLS, a.s.o.)
    • SCTP multi-homing and multi-streaming
  • Asynchronous Processing
