Sebagai input, terdapat jaringan yang cukup besar berdasarkan solusi Cisco, yang telah beroperasi lebih dari 10 tahun dan terdiri dari:
1.348 bangunan dan bangunan;
10.030 jenis titik akses produksi yang berbeda, dimulai dengan sampah langsung AIR-LAP1131G, AIR-LAP1041N (sekitar 88% dari total), diakhiri dengan CAP1602I, CAP2602I, CAP1702I, AP1832I;
WISM1, WISM2, WLC 8540.
Selama lebih dari 10 tahun beroperasi, jalur kabel mulai menjadi tidak dapat digunakan sebagai akibat dari berbagai pembangunan kembali dan perbaikan. Sejumlah besar titik akses dan injektor daya mulai rusak, yang ditambah dengan tren peningkatan konsumsi lalu lintas, menyebabkan keluhan terus-menerus tentang kualitas layanan.
Dengan mempertimbangkan waktu dan kemungkinan anggaran, diputuskan bahwa pada tahap pertama modernisasi jaringan di 589 bangunan akan dikenakan, keputusan untuk modernisasi lebih lanjut akan dibuat setelah menganalisis konsekuensi dari modernisasi saat ini.
Tugas-tugas berikut dirumuskan:
penggantian jalur akses yang gagal dan usang dengan yang baru dan modern;
cakupan bangunan dan tempat tambahan;
penggantian sakelar akses dan injektor daya dengan sakelar PoE;

Dengan pengamatan eksperimental terhadap perilaku titik akses yang sudah terpasang, dan terdapat lebih dari 7500 titik akses pada saat penulisan ini, diasumsikan bahwa jalur komunikasi di mana titik akses memiliki parameter kecepatan eth0 rata-rata di bawah 970 memerlukan rekonstruksi. Mulai dari crimping ulang konektor RJ45 dan mengakhiri, jika perlu, memasang kembali kabel. Jumlah baris masalah tersebut pada saat penulisan ini lebih dari 10% dari jumlah titik akses yang dipantau.
Tugas pemasang sebelum tahun baru adalah memastikan pada 100% jalur kabel kecepatan rata-rata eth0 setidaknya 970.
