LO1.3 – WHAT ARE THE ISSUES AND PROBLEMS WITH ACCESSING MM - NETWORKED Not just the internet could be on a local network. What is bandwidth ? What is bandwidth ? Limitations caused by bandwidth……. Limitations caused by bandwidth……. Limitations on connections…… Limitations on connections…… Limitations on data transfer speeds ……. Limitations on data transfer speeds …….

STAND ALONE VS INTERNET No more internet bills No more internet bills Fast access to hard drive content Fast access to hard drive content Data transfer locally is good Data transfer locally is good Expensive PC Expensive PC Content can go out of date Content can go out of date Updates can be difficult Updates can be difficult Data transfer outside is slow / poor Data transfer outside is slow / poor Cheaper PC Cheaper PC Updates centrally online (once) Updates centrally online (once) Data transfer is easy to distribute Data transfer is easy to distribute Only as fast as your internet speed Only as fast as your internet speed Constant internet costs Constant internet costs Need good bandwidth to cope with demands Need good bandwidth to cope with demands

CABLED VS WIFI Faster data transfer Faster data transfer More stable More stable Need long cable? Need long cable? Limited range? Limited range? Limited number of connections? Limited number of connections? Mobile devices can connect Mobile devices can connect Roaming Roaming Limited range? Limited range? Weak / lost signal Weak / lost signal Connection certificates Connection certificates Limited connections? Limited connections? Less secure Less secure

BANDWIDTH ISSUE More bandwidth = more speed or more connections possible More bandwidth = more speed or more connections possible Imagine a road, single carriageway, compare that to a three lane road. Now move 120 cars down that road. The bigger bandwidth will handle this traffic faster. Imagine a road, single carriageway, compare that to a three lane road. Now move 120 cars down that road. The bigger bandwidth will handle this traffic faster. Can effect both ends of data transfer (sender and receiver) Can effect both ends of data transfer (sender and receiver)

DATA TRANSFER ISSUES GOOD High resolution content High resolution content Connection doesn’t drop Connection doesn’t drop Not pixelated Not pixelated Smooth SmoothBAD Jumpy content Jumpy content Lag Lag Stalling / freezing Stalling / freezing Poor quality resolution / bit rates Poor quality resolution / bit rates Poor transfer speeds mean no transfer or slow transfer. Poor transfer speeds mean no transfer or slow transfer. Live streaming is effected dramatically Live streaming is effected dramatically Sharing content takes a lot longer Sharing content takes a lot longer

CONNECTIVITY ISSUES The more connections – the slower the speed The more connections – the slower the speed Theoretically 255 devices can connect to one wifi access point – In reality the system would slow to a stall / crash well before that number could connect. Theoretically 255 devices can connect to one wifi access point – In reality the system would slow to a stall / crash well before that number could connect. Distance / proximity to a connection can make a difference (go out of range) Distance / proximity to a connection can make a difference (go out of range) Every connection needs its own IP address. If devices share addresses neither will work. Every connection needs its own IP address. If devices share addresses neither will work.
